A transparency report for pet parents
Pet Supplement Brand Transparency Report
How much can a buyer actually verify before trusting the product?
Most pet supplement brands ask pet parents to trust polished packaging, science-sounding language, or badges that do not show the underlying proof. This report looks only at what each brand makes public: doses, ingredient rationale, named experts, testing, manufacturing, evidence, and claim discipline. La Petite Labs publishes the report and is scored separately as a Publisher Benchmark, not included in the rankings.

2026 Executive Summary
Trust language is everywhere in pet supplements. Verifiable evidence is rare.
- Across the 20 ranked brands, the median public-transparency score was 64.8/100 — the field runs from 87 at the top to 42.5 at the bottom.
- Only four of 20 ranked brands let a buyer trace a specific lot number to its own lab report before purchase.
- Only two of 20 disclose the manufacturing facility behind their products at the named-facility level.
- Three of 20 have published a peer-reviewed clinical trial on a finished formula — the rest rely on ingredient-level research.
- Eight of 20 use veterinary-credibility language without naming a single veterinarian anywhere a buyer can check.
- No ranked brand earned the Public Evidence System award in this review cycle.
- If you only do one thing: pick the product you're considering and try to find its per-active doses and its lab report. That two-minute test reproduces most of the spread in this ranking.
- How to read our placement: La Petite Labs publishes this report, so it is graded under the same rubric but shown separately as a Publisher Benchmark — never ranked, never eligible for awards.
What stood out
- 01Doses matter. Brands that hide actives behind proprietary blends make it harder for buyers to compare formulas or to give pets an informed amount.
- 02Testing is not the whole story. A clean COA shows what is or is not in a bottle, but it does not explain why the formula exists.
- 03Named experts matter. "Vet-formulated" means less when no veterinarian is named with credentials and scope of involvement.
- 04Borrowed science is common. Many brands cite ingredient research as if it proves the finished product. Real finished-formula trials are rare.
- 05La Petite Labs does not rank itself. We publish the report, so our score is shown separately as a Publisher Benchmark instead of being mixed into the competitive ranking.
View La Petite Labs roadmap to the 90+ band ↓
Our Publisher Benchmark score is 83.5. The Industry Transparency Standard band begins at 90. The five public-surface commitments below would move La Petite Labs into that band — graded under the same rubric every other brand is held to.
- Ship full-line COA-lookup coverage with a published panel scope. Every currently sold SKU resolves to a public, lot-linked COA; pesticide, mycotoxin, allergen, microbial, heavy-metal, and active-potency testing itemized within the published panel.
- Surface per-active dose disclosure directly on the bundle PDP. Both component supplement facts panels visible side-by-side at the same page depth as the bundle add-to-cart.
- Publish a named per-formula scientific owner for each finished product. Each PDP lists its named scientific owner with credentials, scope (formulated / reviewed / safety-audited), and bio URL.
- Consolidate the trust surface into a single Evidence & Trust hub. One landing page consolidates the four evidence pillars (science, testing, named experts, manufacturing) plus the published rubrics.
- Publish finished-formula clinical evidence on at least one product in the line. Named institution, named principal investigator, registered trial identifier, pre-registered outcomes, results published regardless of direction.
Progress is reviewed at each annual major-update cycle.
Symbol key How to read the badges and watchouts Brand signals · watchouts
Each ranking row earns badges for what the brand publishes well, and may carry up to three Worth Noting watchouts for limitations buyers should be aware of. The same rules apply to every brand on this page, including La Petite Labs.
Public Evidence System
The brand publishes buyer-verifiable evidence across the main pillars — label disclosure, ingredient rationale, clinical evidence, named experts — at a level a buyer can independently check before purchase.
Named Vet Reviewer
The brand surfaces at least one named veterinarian, nutritionist, or scientific advisor with credentials and disclosed scope of involvement (formulator, reviewer, advisor, commentator).
Ingredient Rationale
The brand publishes ingredient-by-ingredient rationale explaining why each meaningful active is in the formula and what biological role it plays.
Disease-Claim-Free
The brand avoids disease-treatment claims, lifespan guarantees, "clinically proven" language without citation, and other consumer-protective language failures across its marketing surface.
Public COA Lookup
The brand publishes a public lookup for Certificates of Analysis (lab reports) so buyers can see test results for actives, contaminants, and microbial purity.
Per-Lot Traceability
Buyers can match a specific bottle or pouch (by lot number) to its own lab report — not just a generic sample COA.
NASC Member
The brand is a current member of the National Animal Supplement Council with active Quality Seal participation.
Finished-Formula Trial
The brand has published a clinical study of the finished formula (not borrowed from an individual ingredient). Distinct from "clinically tested" marketing language.
Named Mfg Facility
The brand discloses its manufacturing facility at the named-facility level (facility name, city, state) with at least one quality-system certification visible.
Worth Noting · watchouts
Watchouts surface honest limitations in a brand's public evidence. Tap any watchout for the institutional meaning.
Closed Science
The brand publishes strong testing or COA evidence but does not surface ingredient rationale, named experts, or finished-formula evidence. Testing alone is not enough to make the science verifiable.
Borrowed Evidence
The brand uses "clinically tested," "clinically proven," "study-backed," or trial-adjacent language without surfacing finished-formula or properly qualified ingredient-level evidence.
Unnamed Experts
The brand uses "veterinarian formulated," "expert designed," or similar language without any publicly named individual, credentials, or role.
Active Identity Withheld
The brand uses proprietary blends, grouped amounts, or other label conventions that prevent a buyer from reading the per-active dose on at least one product in the line. Distinct from Line Inconsistency — captures the case where actives are hidden, not where products differ.
Line Inconsistency
Disclosure varies materially across the brand line — one product is well-disclosed, others are not. Buyers may not know which product they are comparing.
Evidence Buried
The brand technically publishes meaningful science, evidence, testing, or expert disclosure, but buyers cannot reach it without dedicated effort. Evidence that exists but is hard to find counts less.
Higher scores reward
Breadth, disclosure, and substantiation.
- Brands score high when buyers can independently verify the formula, science, named experts, testing, and claims — without emailing support or trusting marketing language.
- Per-active milligram amounts disclosed on the public label.
- Named third-party lab, published Certificate of Analysis, lot-level traceability.
- Public substantiation for marketing claims — citations, not adjectives.
Lower scores may mean
Narrower scope, or less of the work published.
- Brands score lower when evidence is missing, hidden behind support contact, or substituted with vague language ("clinically tested," "veterinarian-formulated," "third-party verified") that cannot be checked.
- Actives are listed without per-serving amounts (proprietary blends).
- Testing language is vague — no named lab, no public COA, no lot linkage.
- Claims outrun the public evidence record at time of review.
A lower score does not automatically mean a product is unsuitable. It may simply be narrower in scope, less transparent, or supported by fewer public quality signals than this rubric rewards.

La Petite Labs, LLC
Publisher of this reportPublisher Brand83.5/100as of 2026-05-23StrongPublisher of this report and excluded from the ranking and from awards. Graded as a Publisher Benchmark under the same rubric and the same standards as every brand surveyed. Strong on label disclosure (per-active mg across the line), scientific rationale (Science Journal indexing proprietary editorial frameworks), evidence and clinical citation (A-D grading + PK tagging + PubMed citations at ingredient level), named veterinary network (six DVMs with framework authorship and review scope), claim discipline, and overall buyer-accessibility (six trust pages within one click of home). Remaining gaps disclosed in the brief: no published finished-formula clinical trial yet on any LPL product, no named per-formula scientific owner tied to Hollywood Elixir, Pet Gala, or the Pampered System, partial COA-lookup rollout across the line, manufacturing identity disclosed at country level only, no above-the-fold 'not a substitute for veterinary care' qualifier on bundle framing, and no consolidated 'Evidence & Trust' hub landing page.
Public Evidence System Named Vet ReviewerIngredient RationaleDisease-Claim-FreePublic COA LookupPer-Lot TraceabilityNASC Member Finished-Formula Trial Named Mfg FacilityWhat's in it
- Per-active mg disclosure across every product in the line, with no proprietary blends.
- Consolidated Science Journal in primary navigation indexing proprietary editorial frameworks authored by named DVMs (Dr. Pendergrass on the 12 Hallmarks of Aging in Dogs; Dr. Calvin on the Pet Integumentary System; plus Cross-Species Formulation, Single-Nutrient vs Systems, Why Many Pet Supplements Fall Short).
- Per-product Research pages cite 8 PubMed-linked peer-reviewed studies with explicit A-D evidence grading and PK1-PK3 pharmacokinetic confidence tagging, separating direct ingredient-level evidence from extrapolated evidence and disclosing that no finished-formula clinical trial has yet been published.
What's not in it
- No named in-house lead formulator publicly tied to the specific Hollywood Elixir, Pet Gala, or Pampered System finished formulas — the veterinary network is framed as scientific review, safety auditing, and framework authorship rather than as named product formulators.
- Manufacturing location disclosed at country level (NASC-audited, FDA-registered, cGMP) rather than at named facility / city / state.
- COA lookup tool exists and is surfaced in primary navigation, but rollout coverage across the product line is still partial — full per-SKU lot-lookup coverage has not yet shipped.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsBoth flagship products (Hollywood Elixir, Pet Gala) and the Pampered System bundle disclose every meaningful active by mg/IU/mcg on the public PDP, with no proprietary blends and clearly defined serving sizes. Hollywood Elixir surfaces NR 60 mg, glutathione 50 mg, CoQ10 40 mg, astaxanthin 2 mg, quercetin 25 mg, beta-glucans 50 mg, reishi 25 mg, plus B-complex and taurine. Pet Gala surfaces 13 actives at full mg disclosure. The bundle PDP requires one click into a component PDP to see the full dose panel side-by-side, which is the only structural gap.Held below 10 because the Pampered System bundle PDP does not yet surface both component dose panels side-by-side on the bundle page itself. Buyers must click into Hollywood Elixir and Pet Gala PDPs individually to compare. A consolidated dose-panel display on the bundle PDP would lift this to 10.Marine Collagen Peptides 500 mg · Hydrolyzed Whey Protein 250 mg · Beef Gelatin 200 mg · Omega 3-6-9 150 mg · MSM 100 mg · Bone Broth 100 mg · Hyaluronic Acid 50 mg · Omega-7 50 mg · L-Carnitine 20 mg · Silica 10 mg · Ceramides 8 mg · Zinc 1.5 mg · Biotin 50 mcgThe brand publishes a consolidated Science Journal in primary navigation that indexes multiple proprietary editorial science frameworks authored by named DVMs: The 12 Hallmarks of Aging in Dogs (Dr. JoAnna Pendergrass, DVM), The Pet Integumentary System (Dr. Sarah Calvin, DVM), The Science of Cross-Species Formulation, Why Single-Nutrient Thinking Often Falls Short, Why Many Pet Supplements Fall Short, Nutrition and Drug Approaches in Pet Health, and Skin and Coat Clues to Systemic Disease. Per-product Research pages articulate ingredient selection, biological role, and mechanism at the active level. The Hollywood Elixir Research page surfaces the LPL-01 design framework, Biological Defense Coverage, the trademarked Canine and Feline Gerosciences framework, and an NAD+ Pharmacology Appendix. Mechanism content is real and substantive, not benefit assertion. Held below 10 only because the brand does not yet publish a single 'How LPL Formulas Work' landing page that consolidates every mechanism page in one anchor.No single consolidated 'How LPL Formulas Work' landing page yet — mechanism content is distributed across the Science Journal index, per-product Research pages, and individual framework pages. Consolidating into one landing page (while preserving the deep pages) would lift to 10.Rather than stacking ingredients, we construct formulas around mechanism, interaction, and long-term biological effect.Pilot-evaluator confirmed directly on the Hollywood Elixir Research page: 8 peer-reviewed studies are surfaced with PubMed links and full publication context (Watowich 2024 Scientific Reports; Schmid 2024 GeroScience; Druzhaeva 2021 AJVR; Abreu 2015 IJP; Reinboth 2010 JAFC; Park 2019 Vet. Med.; Kayser 2024 J. Anim. Sci.; Creevy 2022 Nature). The page applies explicit A-D evidence grading and PK1-PK3 pharmacokinetic confidence tagging to distinguish stronger direct evidence from weaker extrapolated evidence. It separates ingredient-level research from finished-formula research. The brand does not borrow unrelated trials and does not use 'clinically tested' or 'clinically proven' language without underlying support. Held at 8 rather than 9 because the A-D + PK grading framework is applied to ingredient-level evidence only, and no published finished-formula clinical trial yet exists on any LPL product. Ingredient-level evidence with grading discipline is not equivalent to finished-formula evidence; the rubric does not award the 9-10 tier without finished-formula RCT or substantively comparable direct evidence.No published finished-formula clinical trial on any LPL product (disclosed). The A-D + PK1-PK3 grading framework improves evidence legibility by separating direct evidence from extrapolated evidence, but is currently most prominently surfaced on the Hollywood Elixir Research page; extending the same grading discipline visibly to the Pet Gala Research page closes one part of the gap. The 9-10 tier requires a finished-formula RCT or equivalent direct evidence.It applies explicit evidence grading (A–D) and pharmacokinetic confidence tagging (PK1–PK3) to distinguish what is proven in dogs from what is inferred or theoretical.The brand identifies six named veterinary contributors, with scopes ranging from framework authorship to expert commentary and review. Surfaced from primary navigation. Dr. Sarah Wooten (DVM, CVJ — UC Davis): veterinary contributor and pet health journalist. Dr. JoAnna Pendergrass (DVM — Virginia-Maryland CVM, Emory postdoc): publicly named author of LPL's 12 Hallmarks of Aging in Dogs framework. Dr. Sarah Calvin (DVM — Washington State): publicly named author of LPL's Pet Integumentary System framework. Dr. Joseph Menicucci, DVM: dedicated public dossier page. Two additional credentialed contributors named: Dr. Joanna Woodnutt (BVM, BVS, MRCVS) and Dr. Crisanto Villarey (DVM). A dedicated Veterinary Professionals hub provides a separate practitioner-facing surface. Scored 8 under the standardized expert ladder: multiple named DVM advisors with framework-level scope, but no named lead formulator or scientific advisor tied specifically to the finished Hollywood Elixir, Pet Gala, or Pampered System formulas. The 9-10 tier requires explicit per-formula scope of ownership (formulated / reviewed / safety-audited / medically reviewed) attached to specific finished products.No named in-house lead formulator or scientific advisor publicly tied to the specific Hollywood Elixir, Pet Gala, or Pampered System finished formulas. The veterinary network is well-disclosed at the framework-authorship level; the 9-10 tier requires explicit per-formula formulation ownership or safety-review scope attached to specific finished products.La Petite Labs collaborates with veterinarians and scientists who provide scientific review, safety auditing, and expert commentary on our proprietary frameworksPilot-evaluator confirmed directly on the Quality & Testing Standards page: NSF and Eurofins are both named as third-party laboratory partners. The page describes per-batch testing covering heavy metals, microbial contamination, and active-ingredient potency. A dedicated Verify Your COA portal is surfaced from primary navigation with a working lot-number lookup field. NASC Quality Seal participation and FDA registration are disclosed. Held at 8 (not 9) because the brand discloses on its own COA page that lot-lookup rollout is still in progress — Hollywood Elixir lot-lookup goes live June 2026, Pet Gala completes by end-of-year, Pampered System not yet covered. The COA page itself states 'Some older or transitional batches may not yet be available in the lookup system' — disclosed rollout state rather than over-promise. Score will lift to 9 the moment lot-lookup is live for every currently sold SKU, and to 10 when surfaced directly on each PDP and when the panel scope (pesticides, mycotoxins, allergens) is explicitly itemized.Coverage across line is currently 'partial' rather than full. Score is held at 8 until lot-lookup is live for every currently sold SKU. The lot-lookup tool is also best surfaced on individual product PDPs (not only on the Quality & Testing Standards page and the dedicated COA portal). Additionally, the Quality & Testing page does not yet explicitly itemize pesticide, mycotoxin, and allergen testing within the third-party panel.This service is available for Hollywood Elixir® starting June 2026. Pet Gala™ will complete its lookup service roll-out by end-of-year.The brand publicly discloses U.S. manufacturing location at the country level, NASC-audited facility status, FDA-registered facility status, and cGMP language. NASC member directory listing is publicly verifiable. Sourcing logic is described in editorial copy. The structural gap is that the specific facility name, city, and state are not currently surfaced publicly — manufacturing location is disclosed at the country level rather than the named-facility level the rubric rewards at the 10/10 tier. Quality system is fully disclosed (NASC + FDA + cGMP); facility identity is not.Named facility (name, city, state) is not surfaced publicly. NASC membership is verifiable in the NASC directory but is not directly linked from the Quality & Testing page. HACCP, SQF, and ISO certifications are not disclosed (these are not required but would tighten the score). Both facility naming and a direct NASC-directory link would lift toward 10.Every batch is tested under a NASC-compliant quality system, with independent third-party verificationBrand marketing across home page, PDPs, What-Is pages, and Research pages avoids disease-treatment claims, exaggerated lifespan claims, 'clinically proven' language without citation, and unsupported before/after implications. The brand explicitly discloses that no finished-formula clinical trial currently exists on its products, rather than using clinical-style language to imply otherwise. The 'Why Many Pet Supplements Fall Short' framework and the public Editorial Guidelines page articulate the brand's claim-discipline thesis. Scored at 8 (not 9) because above-the-fold framing on the home page and the bundle PDP uses 'complete daily wellness system' language that, while explained in supporting copy, is not qualified above-the-fold with an inline limit such as 'not a substitute for veterinary care or complete nutrition.' Score lifts to 9 the moment above-the-fold qualifiers are added.Above-the-fold 'complete' framing on the bundle PDP and home page carries no inline qualifier. Adding 'not a substitute for veterinary care or complete nutrition' (or equivalent) above-the-fold would lift this to 9. Tightening every broad 'wellness system' phrase across major surfaces is the gate to 10.the finished formula does not yet have a published clinical trialPrimary navigation surfaces six trust pages within one click of the home page: LPL-01 Standard, Science Journal, Veterinary Experts, Quality & Testing Standards, Flavor & Palatability, and Verify Your COA. Each product line additionally exposes dedicated What Is, Research, Quality & Testing, Ingredients, and Benefits pages from its own sub-navigation. The four evidence pillars (science, testing, named experts, manufacturing) are each addressable in one click. Held below 10 only because the brand does not yet consolidate these into a single 'Evidence & Trust' hub landing page — buyers reach evidence quickly, but via multiple top-level links rather than one anchor.Six trust pages exist in primary nav but are not consolidated into a single Evidence & Trust hub. Building one anchor page that links to Science Journal, Quality & Testing, Verify Your COA, Veterinary Experts, LPL-01 Standard, and the published rubrics would lift this to 10.evidence-aware pet wellness resources grounded in formulation transparency, species-appropriate safety logic, and the LPL-01 StandardReviewed May 23, 2026Sources: 23 sources reviewedExplore La Petite Labs →0LPLLa Petite LabsPublisherLa Petite Labs, LLC · Core Publisher of this reportPublisher of this report and excluded from the ranking and from awards.

ElleVet Sciences
ElleVet Sciences
South Portland, Maine, United States87/100as of 2026-06-13StrongElleVet Sciences sits well above the category median on research and expert disclosure: it cites peer-reviewed finished-formula trials with authors and journals, names a credentialed CMO and Advisory Board from primary navigation, and runs a public lot-linked COA lookup with a named lab. The gaps are in label granularity (cannabinoids grouped as a proprietary CBD + CBDA total), COA panel scope (potency-only on the surfaced certificate), and facility-level manufacturing identity, which stays at region and corporate-HQ level.
Public Evidence System Named Vet ReviewerIngredient RationaleDisease-Claim-FreePublic COA LookupPer-Lot TraceabilityNASC Member Finished-Formula Trial Named Mfg FacilityWhat's in it
- Publishes roughly 18 studies with author, institution, journal, and direct links, the majority peer-reviewed finished-formula trials on ElleVet's own CBD + CBDA blend rather than borrowed ingredient research.
- Surfaces a fully named Chief Medical Officer (Dr. Joseph Wakshlag, DVM, PhD, DACVIM, DACVSMR) and a deep Advisory Board of board-certified diplomates with detailed bios, reachable from primary navigation.
- Operates a public, self-serve, lot-linked COA lookup with the third-party lab (ProVerde) named, and publishes detailed receptor-level ingredient mechanism content on its Science page.
What's not in it
- Cannabinoid actives are disclosed as a combined CBD + CBDA total under a proprietary complete-spectrum label across the line, with minor cannabinoids and terpenes unquantified per serving.
- The publicly pullable COA shows cannabinoid potency only; the heavy-metal, pesticide, and microbial panels described in the FAQ are not surfaced on the lot certificate.
- No dedicated manufacturing, quality, or sourcing page exists; the manufacturing/extraction facility is not named at facility/city/state level and no cGMP, FDA-registered, HACCP, SQF, or ISO certification is disclosed beyond the NASC seal.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsEvery reviewed PDP publishes a per-serving active panel with defined serving sizes and a full alphabetical inactive-ingredient list. The Soft Chews disclose Glucosamine (Shellfish) 340mg / 510mg and Chondroitin (Bovine) 140mg / 210mg per small and large chew respectively, and all cannabinoid SKUs state a combined CBD + CBDA milligram figure: oil at 70mg/mL, soft gels at 3.8mg / 11.3mg / 28mg / 37.5mg per size, and Calm & Comfort at 46mg per 6g chew. The limiting pattern is line-wide rather than SKU-specific: the cannabinoid actives are presented as a proprietary complete-spectrum total ('ElleVet Complete Spectrum Proprietary Hemp Oil 20mg (contains 12.8mg of CBD + CBDA and other minor cannabinoids)') rather than itemizing CBD and CBDA separately, and the minor cannabinoids and terpenes are never quantified per serving on the label. The example COA for lot R9005-14 does break the blend into CBD 34.565 and CBDA 33.033 mg/mL, so the split is verifiable at the batch level even though it is grouped on the panel. Disclosure is therefore strong and consistent on the primary actives but relies on a grouped, proprietary-blend figure for the cannabinoid component across the whole line.The score is held below 8 because the cannabinoid actives are disclosed as a combined CBD + CBDA total under a proprietary complete-spectrum label across every SKU, and the minor cannabinoids and terpenes are unquantified per serving. Itemizing CBD and CBDA separately on the panel and publishing per-serving amounts for the minor cannabinoids and terpenes (rather than 'and other minor cannabinoids') would lift it toward 9-10.Soft Chews contain our proprietary oil formulation, as well as glucosamine and chondroitin.The /cbd-science/ page is an unusually deep ingredient-rationale resource for the category. It explains the endocannabinoid system and then names the specific receptor systems ElleVet attributes the response to, walking through TRP channels, GPR55, PPAR-g, the 5HT1A and 5HT3A serotonin receptors, the glycine receptor, and adenosine transport, and explicitly argues the CB1/CB2 receptors are not the operative mechanism at achievable serum concentrations. It separates the biological roles of CBDA versus CBD (CBDA absorption and serotonin/anti-inflammatory effect), describes FAAH enzyme inhibition, and gives terpene-by-terpene rationale (myrcene, limonene, alpha-pinene, beta-caryophyllene, humulene, linalool) plus the entourage effect. The glucosamine and chondroitin in the chews appear as named label actives without a comparable mechanism or benefit explanation on the reviewed pages. Because the cannabinoid blend is the core active across the entire line and its mechanism is documented exhaustively with supporting research cited on the same page, rationale coverage is near-complete.The score sits at 9 rather than 10 because the secondary joint actives (glucosamine, chondroitin) are surfaced as label ingredients without a mechanism explanation, and mechanism content is concentrated on the central Science page rather than restated per product. Adding ingredient-level mechanism and citations for glucosamine and chondroitin would complete the criterion.ElleVet’s research has shown that it is far more complex and that the receptors involved include the TRP, GPR, PPAR-g GPR55, 5HT, glycine, and adenosine uptake receptors.ElleVet's research disclosure is the strongest element of its surface. The Science page lists roughly 18 studies, each with a title, date, study design, quantified result, named lead researcher (Wakshlag, Deabold, Court), institution (Cornell, University of Florida, Washington State, Utrecht), journal or publisher, and a direct link to the publication in Frontiers, MDPI, Wiley, Dovepress, SAGE, or AVMA journals. Crucially, the trials are run on ElleVet's own finished CBD + CBDA blend rather than borrowed ingredient research: the oil is described as 'the exact blend that is used in our clinical trials', and there are published finished-formula studies on mobility (Cornell), sensitive skin (a randomized, double-blinded, placebo-controlled trial, n = 17 treated), neurological events, feline mobility, and safety/drug-interaction work. The For Veterinarians page states the brand has 'completed and published more than 20 peer-reviewed studies' as of January 2026. The brand distinguishes its finished-product evidence clearly and does not present unrelated ingredient trials as finished-formula proof.The criterion's 10 anchor is met. The only residual nuance is that several of the more recent reports (Calm & Comfort, dental stick, equine pellets, feline urinary) are white papers hosted on the ElleVet domain rather than peer-reviewed journal articles; labeling each report's peer-review status inline would remove any ambiguity between published trials and self-hosted white papers.Dogs were randomly assigned to receive either 2 mg/kg of an equal mix of CBD/CBDA rich hemp from ElleVet Sciences (n = 17) or placebo for four weeks.Named expert disclosure is comprehensive and reachable from primary navigation (About > Meet the Team). Dr. Joseph Wakshlag is surfaced as Chief Medical Officer and Chair of the Advisory Board with full credentials (DVM, PhD, DACVIM Nutrition, DACVSMR, Professor at Cornell) and a documented role and scope: he conducted the first ElleVet clinical trial and the first pharmacokinetic and safety studies. Beyond him, a full Advisory Board of board-certified diplomates is listed with detailed bios, including specialists across surgery and sports medicine (Adair, Kaneps), behavior (Albright), dermatology (Santoro, whose specialty maps to the published skin trial), internal medicine and cardiology (Ettinger, Kornreich), orthopedics and osteoarthritis (Kirkby Shaw), neurology (Wininger), pharmacovigilance (Elam, also ElleVet's Director of Pharmacovigilance), and regulatory science (McChesney, a former FDA CVM compliance director). Two staff veterinarians, Dr. Robert Menardi (Senior Director of Veterinary Education) and Dr. David Tittle (International Scientific Advisory Board), have dedicated bio pages with credentials and scope.The 10 anchor is met. A minor refinement would be to name a single lead formulator for the finished products; the formulation is attributed to the founders working with biochemists and to Dr. Wakshlag's research rather than to one named formulator, though the CMO and advisory disclosure more than satisfy the criterion.Dr. Wakshlag conducted the first ever clinical trial on dogs using ElleVet CBD + CBDA and continues to lead the way in hemp research.ElleVet operates a genuine public, self-serve, lot-linked COA program. The COA library explains where the batch number is printed on each SKU and provides a search field ('enter batch number here') that returns the matching certificate, and a live example for lot R9005-14 confirms lot-level traceability with a full cannabinoid potency panel (CBD 34.565, CBDA 33.033, D9-THC 1.837 mg/mL, total cannabinoids 75.367). The third-party laboratory is named: ProVerde. The FAQ additionally describes a multi-stage third-party testing program in which the extract is tested for contaminants and final batches are tested for potency. The limiter is panel scope on the surfaced certificate: the COA a buyer can actually pull is potency/cannabinoid-only and does not display the heavy-metal, pesticide, microbial, or residual-solvent results that the FAQ says are tested upstream.The score is held at 9 because the publicly accessible COA surfaces cannabinoid potency only; the contaminant and microbial panels are described in FAQ prose but their results are not shown on the lot certificate. Publishing the heavy-metal, pesticide, microbial, and residual-solvent results on each lot's COA would complete the 10 anchor.Proverde, the 3rd party lab that tests our products, does not test for CBCa, which accounts for 2-3% of our profile.ElleVet discloses a recognized quality-system seal and a clear sourcing narrative, but holds facility identity above the facility level. The FAQ states NASC membership ('We are proud to display the NASC Quality Seal', with the NASC seal image also rendering on the home page) and provides sourcing logic: the brand says it controls 'our products entire cycle - from the farm to the end-user', that it does 'not buy from a bulk manufacturer', that the hemp is a proprietary cultivar grown under 'strictly controlled growing in Colorado', and (on the Hemp page) describes cold hydrocarbon extraction as its preferred method. What is not disclosed is the manufacturing or extraction facility at name/city/state level: probes of /manufacturing/, /quality/, /sourcing/, /gmp/, and /certifications/ all return 404, and the only street address published is the corporate HQ at 200 John Roberts Rd., South Portland, Maine. No cGMP, FDA-registered-facility, HACCP, SQF, or ISO certification is named.The score is held at 8 because the quality system surfaced is NASC plus sourcing logic, while facility identity stays at region (Colorado growing) and corporate-HQ level rather than naming the manufacturing/extraction facility. Naming the facility (name, city, state) and disclosing a facility certification such as cGMP or FDA registration would lift it toward 9-10.At ElleVet, we control our products’ entire cycle - from the farm to the end-user. We do not buy from a bulk manufacturer.ElleVet's claims are unusually well supported relative to the category, yet the framing runs confident. The home hero carries an unqualified 'Scientifically Proven' badge and product pages use 'proven' language ('Our proprietary CBD + CBDA has been proven to help decrease joint discomfort'), while the broader marketing leans on superlatives such as being 'the only product proven effective in multiple clinical trials.' These claims do trace to real published finished-formula trials, the site consistently carries the FDA structure/function disclaimer ('not intended to diagnose, treat, cure or prevent any disease'), review modules state results 'are not guaranteed, are not medically substantiated', and the home page qualifies its vet-endorsement claim with a footnote naming the Cornell double-blind study. The brand avoids overt disease-cure language. The remaining tension is that the strong 'proven' framing appears above the fold with the supporting citation living a click away on the Science page rather than inline; the per-benefit support claims are more cautiously worded (the home page frames the neurological benefit as 'CBD + CBDA can support healthy brain function'), so the headline 'Scientifically Proven' badge and the comparative 'only product proven' superlatives carry the confident framing without an inline citation.The score is held at 8 because confident 'proven'/'Scientifically Proven' framing appears above the fold without an inline citation or qualifier, and the comparative 'only product proven' superlatives sit a click away from their supporting studies rather than beside the claim. Moving the specific study citation inline beside each 'proven' claim and superlative would lift it toward 9-10.Our proprietary CBD + CBDA has been proven to help decrease joint discomfort and improve overall mobility, allowing your dog to get back to doing what they love.Three of the four evidence pillars are reachable with little effort. The Science (mechanism and study list) lives on a top-level 'Science' nav item, and named experts are one level down under About > Meet the Team, both in the primary header. Testing is reachable through the footer 'Certificate of Analysis' link, which opens a working self-serve batch lookup. The weaker pillar is manufacturing and sourcing: there is no dedicated manufacturing, quality, or sourcing page (those URLs 404), so a buyer must dig into the FAQ to find the Colorado-growing and farm-to-end-user disclosures. Evidence is also split between header and footer rather than gathered into a single consolidated trust hub, and the research list and COA library are footer-only.The score is held at 8 because the COA library and research list are footer-only, manufacturing/sourcing detail is buried inside the FAQ with no dedicated page, and there is no single consolidated 'Evidence & Trust' hub.

United States75/100as of 2026-05-23Solid With GapsFera Pets presents above the DTC median on named-expert disclosure and operates a real lot-linked COA lookup. The brand publishes mechanism content with ingredient-level citations and avoids disease-treatment claim language. Substance gaps cluster on the legacy product line — flagship chewables disclose every active dose while powders and toppers fall back to total-blend amounts — and on facility-level manufacturing identity, which is held at country and certification-body level only.

Disclosure varies materially across the brand line — one product is well-disclosed, others are not. Buyers may not know which product they are comparing.
What's in it
- Fully named five-member Vet Advisory Board with two ACVIM/ACVD board-certified diplomates and disclosed credentials — one of the stronger named-expert disclosures in the DTC pet supplement universe.
- Functional lot-linked COA lookup tool accepting LOT numbers or product names — real buyer-usable testing transparency rather than a placeholder badge.
- Brand-level Ingredients encyclopedia publishes per-ingredient mechanism content with linked peer-reviewed studies for most meaningful actives, including ashwagandha, milk thistle, glucosamine, and probiotic strains.
What's not in it
- Label transparency varies materially across the line: chewable SKUs disclose every active in mg / IU / CFU while legacy powders (Probiotic Supplement, Mushroom Blend, Whole Food Multivitamin Topper) use total-blend amounts or generic descriptors.
- Manufacturing facility is not named at facility / city / state level — only 'manufactured in the USA in an FDA-registered GMP facility, NASC certified' country-level disclosure.
- COA panel scope (which contaminants, microbials, potency assays) is not surfaced on the public Sustainability hub; third-party lab (Eurofins) is named only on the Fish Oil PDP rather than consistently across the line.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsDisclosure tier varies materially across the line. The chewable and liquid SKUs reviewed (Hip + Joint Support, Multivitamin Soft Chews, Wellness Blend for Cats, Fish Oil for Dogs) publish full per-active mg/IU/CFU panels with inactives, serving sizes, and (in Wellness Blend and Multivitamin Chews) strain-level probiotic identifiers. The legacy powder SKUs are weaker: USDA Organic Probiotic Supplement names 12 species at genus/species level only with a total CFU rather than per-strain CFU; USDA Organic Mushroom Blend discloses a 500 mg total blend across ten mushroom species without per-species mg amounts; Whole Food Multivitamin Topper lists key ingredients with mechanism descriptors but no per-active doses. Brand uses 'proprietary blend' marketing language on Hip + Joint despite the active panel being fully numerically disclosed — verbal friction without actual obfuscation. Modal-product score reflects the dispersion: the flagship chewables clear an 8, but powders and toppers do not.Legacy powder SKUs (Probiotic Supplement, Mushroom Blend, Whole Food Multivitamin Topper) do not publish per-active amounts at the disclosure tier the chewable SKUs achieve. Strain-level CFU is named on Wellness Blend and Multivitamin Chews but not on the flagship Probiotic Supplement.Our Mushroom Blend has anywhere between >16-50% Beta Glucans. It changes between batches due to variations in mushrooms.The brand-level Ingredients encyclopedia publishes per-ingredient mechanism content — biological role, plausible action, and selection rationale — for the majority of meaningful actives in the line. PDPs reinforce mechanism framing at the product level (turmeric, glucosamine, MSM, postbiotic action, lysine/taurine roles). The Ingredients page filters by both product and benefit category, which is a buyer-usable structure rather than a marketing-copy dump. Where it falls short of a 9 is uniformity: legacy SKUs (Mushroom Blend) describe ingredients in benefit terms more than mechanism terms, and the Whole Food Multivitamin Topper's mechanism content is single-sentence per ingredient. The brand does not publish a unifying scientific framework or finished-formula design rationale separate from per-ingredient logic.No brand-level scientific framework explaining finished-formula design (versus per-ingredient mechanism). Mechanism content is uneven across the line — strong on flagship chewables, thinner on legacy powders.Silymarin is a powerful antioxidant that supports normal inflammatory response.Citation discipline is present and uneven. Hip + Joint cites four studies including a peer-reviewed glucosamine/chondroitin review; Multivitamin Soft Chews link a randomized double-blind glucosamine/chondroitin trial AND a Bacillus subtilis DE-CA9 study; Wellness Blend for Cats links three peer-reviewed papers (green-lipped mussel, cranberry, taurine); the Ingredients hub links additional studies (ashwagandha, milk thistle, etc.). All cited research is ingredient-level rather than finished-formula. The brand uses 'clinically studied probiotic' for the named strain (DE-CA9) — which is defensible because the strain itself has a published trial — but does not separately publish a finished-formula clinical study. The brand also avoids 'clinically proven' language at the product level, which is the right call given the actual evidence inventory. The flagship USDA Organic Probiotic Supplement is the weak point: 12 species listed without strain identifiers means the linked prebiotic studies do not function as evidence for the probiotic claim.No finished-formula clinical trial published or referenced. Citation depth varies — flagship chewables carry multiple studies; the legacy probiotic SKU carries only prebiotic-component studies without strain-level probiotic evidence.Bacillus subtilis DE-CA9 effect on fecal scores and serum oxidative markers in healthy dogs.Five named veterinarians are surfaced with credentials, photographs, and biographical detail on a dedicated Vet Advisory Board page reachable from the footer and the mega-menu. Two of the five hold ACVIM or ACVD board specialty diplomate status — a substantive tier above the generic 'our vet team' framing that defines most DTC competitors. The founder Dr. Michelle Dulake (DVM, acupuncturist) is named and credentialed as formulator; her education, internship, and certifications are all disclosed. Where the disclosure falls short of a 10 is scope-of-involvement specificity: the brand describes the board as 'advisory' without explicitly disclosing per-product review responsibility, formulation veto power, or named ownership of specific SKUs. Buyers can verify WHO the experts are; they cannot fully verify WHAT each expert did on which product. Still, this is one of the stronger named-expert disclosures in the DTC pet supplement universe.Scope of involvement is described in general advisory terms without explicit per-product review attribution or formulation authorship beyond the founder.Dr. Amy Schnedeker, DVM, MS, DACVD - Board Certified Veterinary DermatologistFera operates a real, functional, lot-linked COA lookup tool accessible from the Sustainability page. The tool accepts LOT numbers OR product names — a genuine buyer-usable interface rather than a placeholder. NASC Seal of Quality membership is held, and FDA-registered GMP manufacturing is asserted at the brand level. The substance gap is in the panel scope: the Sustainability hub does not publicly disclose what each COA actually tests for (heavy metals, microbials, potency, pesticides, identity), nor does it name the lab consistently. The third-party lab is named — Eurofins — only on the Fish Oil PDP; the umbrella Sustainability + COA lookup interface uses generic 'certified 3rd party labs' language. Coverage is described as per-batch but not enumerated by SKU. The result is mid-tier: real testing infrastructure, real lot-linkage, but the buyer cannot independently see what was tested against which spec without opening individual COA records.Test panel scope (which contaminants / microbials / potency assays) is not surfaced on the public Sustainability hub. Lab identity (Eurofins) is named only on Fish Oil PDP, not consistently across the line.Every Fera Pets batch is tested by certified 3rd party labs.Quality-system language is present: 'manufactured in the USA in an FDA-registered GMP facility, and NASC certified.' Three structural signals (US country, FDA registration, NASC seal) are disclosed at the brand level. The disclosure ceiling is set by the absence of facility identity — Fera does not name the manufacturing facility, city, or state. Sourcing logic is partially disclosed (fish oil geographic sourcing — Iceland, Peru, Argentina — appears on the Fish Oil PDP) but not systematically across the line. NASC explainer page describes the audit framework generically without disclosing Fera's specific audit findings or date.Manufacturing facility is not named at the facility / city / state level. Sourcing logic is sporadic (named for fish oil; absent for most other actives). NASC audit findings and dates not publicly disclosed.All our supplements are manufactured in the USA with domestic and imported ingredients in an FDA-registered GMP facility, and NASC certified.Brand marketing stays inside supportable claim language. Product benefits are framed as 'supports,' 'helps,' 'eases occasional stiffness,' 'maintains healthy cartilage' — not disease-treatment or cure language. The home page hero does not assert 'clinically proven' or 'veterinarian-approved' claims; promotional copy emphasizes discounts and category positioning rather than clinical certainty. Where the brand uses 'clinically studied,' it points specifically to the named strain (DE-CA9) that does have a published trial — defensible. Fera does NOT publish disease-state claim language on the surveyed surface. The score holds below 9 because (a) the home page does not carry above-the-fold qualifying language ('not intended to diagnose...') visible to a casual buyer, (b) some product copy uses 'proprietary blend' marketing language even when the active panel is fully numerically disclosed, and (c) the brand's 'Vet Created' phrasing is broader than the actual scope of the Vet Advisory Board's per-product role.No above-the-fold safety qualifier. 'Vet Created' framing implies a tighter formulation tie than the advisory board's disclosed scope. 'Proprietary blend' marketing on dose-disclosed panels creates avoidable verbal friction.Helps Relieve Occasional Joint StiffnessEvidence pages are reachable within three clicks from the home page. Header navigation surfaces About and a quiz; the mega-menu and footer carry direct links to About Us, Vet Advisory Board, Sustainability (which hosts the COA lookup tool), FAQ, Ingredients, Store Locator, and Blog. The four pillars all have findable surfaces: science (Ingredients), evidence (PDP citations), experts (Vet Advisory Board), testing (Sustainability + COA Lookup). The accessibility ceiling is set by the absence of a single consolidated 'trust hub' — pillars are distributed across separate pages, so buyers must navigate to multiple destinations rather than landing in one evidence index.

New York, NY74/100as of 2026-06-13Solid With GapsPetLab Co presents well above the DTC median on named-expert disclosure and claim qualification: a seven-member named advisory board with per-member scope of involvement, formulation-scope credits, and footnoted clinical claims with study durations and endpoints. Label panels are structured line-wide, with proprietary-blend totals on probiotic SKUs. Its Probiotic Chew finished-formula study is published in a peer-reviewed journal and identifiable by named author, but the brand does not link it on-site, the ProBright Advanced studies are not published or identified, no laboratory is named, and no COA or lot lookup exists — so most testing and clinical claims still cannot be inspected before purchase.

Disclosure varies materially across the brand line — one product is well-disclosed, others are not. Buyers may not know which product they are comparing.
What's in it
- Named-expert disclosure is among the deepest in the DTC set: a seven-member Scientific Advisory Board in primary navigation, each member carrying a credentialed bio plus an 'At PetLabCo.®' statement of their specific role, formulation-scope credits for Dr. Greg Sunvold, Ph.D. and Dr. Jan Bellows (American Veterinary Dental College), and a named reviewing veterinarian (Dr. Sarah Cortright, DVM) behind the sitewide 'Vet Reviewed' badge.
- Claim qualification is systematic: clinical-style statements carry inline daggers resolving to on-page footnotes with study durations, endpoints, and control-group context; marketing statistics are explicitly labeled as internal subscriber surveys with dates and sample sizes; and the Probiotic Chew finished-formula study is published in a peer-reviewed journal (Zilinger et al., 2026, Pets) and credited on-site by named author.
- Label panels are complete and structured on every product reviewed — named actives with per-serving amounts, serving sizes, inactive ingredients, and cautions — reaching per-active mg disclosure with EPA/DHA splits and supplier trademark attribution on the non-probiotic chews.
What's not in it
- Of the three cited finished-formula clinical studies, only the Probiotic Chew study is published (peer-reviewed, identifiable by named author); the 28-day and 90-day ProBright Advanced studies are not published or identified by author, journal, or registry, and the brand does not link the published study on its own pages.
- Testing claims stop above the artifact layer: no third-party laboratory is named, no certificate of analysis is published, and no lot-level lookup exists anywhere on the brand surface, with common testing/COA URL patterns returning 404.
- Probiotic SKUs — including the flagship Probiotic Chews — label actives as proprietary blends with total CFU only, and manufacturing identity is held at 'Manufactured in the USA' country level with no facility name, city, or state.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsEvery PDP reviewed publishes a structured Product Facts panel with named actives, per-serving amounts, serving size, inactive ingredients, and cautions — including multi-size SKUs that tabulate doses per chew or scoop size. Joint Care Chews disclose every active in mg per 4 g chew (Glucosamine 450 mg, Green Lipped Mussel 150 mg, Total Omega-3 48 mg with EPA 24 mg / DHA 15 mg splits, Calcium Fructoborate 35 mg, Turmeric 25 mg); Itch Relief Chew Pro and the Multivitamin reach the same tier, down to supplier trademark attributions for AstaReal L10 and Enzalox and a full guaranteed-analysis vitamin panel. The probiotic side of the line holds back: Probiotic Chews label 'A Proprietary Blend of Probiotics (Bacillus coagulans, B. clausii, B. subtilis)' at a total 3 Billion CFU with no per-species counts, and the same blend-total pattern covers Allergy & Immune Chews (1–3 Billion CFU across three sizes), Probiotics for Cats (six species, 2.1 Billion CFU), Anal Gland Support (750 Million CFU), and ProBright Advanced's patent-pending two-species blend. Mobility Pro Oil is the thinnest panel: 'A Proprietary Blend of Curcumin & Zinc Chloride 425 mcg' with no split between the two actives. Modal disclosure is per-active amounts inside a consistent panel template, with a recurring blend-total exception wherever probiotics or blended oils appear — including on the brand's self-described best-selling probiotic flagship.Proprietary-blend labeling on the probiotic SKUs — including the flagship Probiotic Chews — and the grouped curcumin/zinc figure on Mobility Pro Oil keep the line below the 8 tier. Publishing per-species CFU counts (or strain identifiers with per-strain amounts) and splitting the Mobility Pro Oil blend would lift the score.A Proprietary Blend of Probiotics (Bacillus coagulans, B. clausii, B. subtilis)Ingredient rationale is template-consistent across the line rather than flagship-only. Every PDP reviewed carries a 'Research-Backed Active Ingredients' module with a card per active stating its class and physiological role — Glucosamine HCl as 'This amino sugar helps maintain joint lubrication and supports healthy cartilage,' FOS as 'a versatile prebiotic fiber that feeds beneficial bacteria' — and a brand-level Ingredients glossary ('50+ Premium Pet Supplement Ingredients,' reachable from the About menu) repeats per-ingredient purpose blurbs filterable by health area. The About page adds selection logic for hero inputs: non-heat-treated whole Green-Lipped Mussel chosen for 'the highest levels of lipids and omega-3 fatty acids,' and colostrum selected for immunoglobulin and lactoferrin content. Depth, however, stays at one-to-two-sentence role language: meaningful actives are described in benefit-and-role terms rather than worked mechanism explanations, and no ingredient card or glossary entry links to the 'robust scientific research' the brand says stands behind its key ingredients.Rationale never connects to citable research — no PubMed, journal, or author references appear on any PDP or on the Ingredients glossary. Per-ingredient citations and fuller mechanism write-ups for the major actives would move the score toward 9–10.every ingredient is carefully selected with a purpose - to target common health issuesPetLab Co's clinical-evidence story is unusually specific for the DTC tier and explicitly scoped to the brand's own finished-formula studies, not borrowed ingredient research. The Ingredients page states 'ProBright® Advanced and Probiotic Chew formulas are backed by clinical studies to demonstrate effectiveness,' limiting finished-formula study claims to two named products, and the claims carry on-page footnotes with design detail: a 28-day hydrogen-sulfide reduction study, 'In a 90-day clinical study, dogs taking ProBright® Advanced daily had a plaque index score that was 25% lower than the control group,' and 'A 29-day clinical study showed using Probiotic Chew daily enhances beneficial gut bacteria.' For the Probiotic Chew, the brand goes further than a footnote: a learn-section article (in the crawl inventory) describes the finished-formula study in full — 'PetLabCo. funded a randomized, placebo-controlled clinical study,' 24 healthy adult Beagles for 31 days, Day 0/14/31 sampling, a reduction in fecal calprotectin, and all three Bacillus species increasing — and attributes it inline to a named first author and year, '(Zilinger et al., 2026).' That study is genuinely published and identifiable: Zilinger et al. (2026), 'Effect of a Supplement Containing Probiotics, Prebiotics, and Yeast Extract on Gut Inflammation, Microbiota, and Cytokines in Healthy Dogs,' Pets (MDPI), DOI 10.3390/pets3010001 — a peer-reviewed, open-access paper whose composition matches the Probiotic ChOne finished-formula study (Probiotic Chew) is published and identifiable by named author, but the brand does not hyperlink it from the PDP or the learn article, and the ProBright Advanced 28-day and 90-day studies carry no author, journal, registry entry, or link. Directly linking the published Probiotic Chew paper and publishing or identifying the two dental studies (author, venue, or registry) would lift the score toward 8; peer-reviewed publication of all three with on-page citations would support 9–10.In a 90-day clinical study, dogs taking ProBright® Advanced daily had a plaque index score that was 25% lower than the control group.The Experts entry in the primary About menu opens 'PetLabCo.®'s Scientific Advisory Board,' naming seven individuals with photos, titles, and capsule credentials: Gregory D. Sunvold, Ph.D. (Chief Scientist), Dr. Jan Bellows (Board Certified Veterinary Dentist, American Veterinary Dental College, practicing since 1977), Dr. Gavin Casper (Fear-Free certified veterinarian), Jessica Bagel (Clinical Trial Manager, DVM graduate from NCSU with 13+ years at UPenn), Dr. Margie Scherk (feline specialist, board-certified since 1995), Dr. Stephanie McGrath (Associate Professor of neurology at Colorado State University), and Dr. Matt Kaeberlein (Co-Director of the Dog Aging Project). Beyond credentials and a full external-career biography, each member's on-page 'Meet Dr. [name]' profile carries an 'At PetLabCo.®' block stating that member's specific scope of involvement: Sunvold 'leads product formulation science' and co-authors clinical trial protocols and reports; Bellows serves as Chief Dental Specialist 'helping with product formulation and testing, clinical trial protocol design and report authoring'; Bagel runs clinical-trial protocol design and execution; Casper reviews ingredients for joint-health effectiveness; Scherk 'helped in the development of our first Cat Product – Cat Probiotic'; McGrath leads protocol design of the senior-dog/Longevity trial with Colorado State University as the executing CRO; and Kaeberlein collaborated on the Longevity supplement and its trial protocol.Disclosure meets the 10 anchor: seven named advisors reachable from primary navigation, each with credentials, a full biography, and an 'At PetLabCo.®' scope-of-involvement statement. Two minor refinements remain — the per-member PetLab scope sits one click into each card's profile panel rather than in the always-visible capsule, and the formula-reviewing veterinarian named in the home FAQ (Dr. Cortright) is surfaced on the home page but not added to the Experts roster itself.Every formula is thoroughly reviewed by Dr. Sarah Cortright, DVM, our trusted Veterinary Consultant at PetLabCo.®Testing disclosure is assertion-level. The About page commits to batch testing in named categories — 'Every batch is rigorously tested for harmful contaminants, heavy metals, allergens, and toxins' — and to third-party verification: 'Every formula undergoes independent third-party testing to confirm purity, potency, and label accuracy.' Every PDP reviewed repeats a 'Third-Party Tested' trust block ('Rigorously tested for quality and potency'). But no testing laboratory is named anywhere on the reviewed surface, no certificate of analysis is published or retrievable, and no lot or batch mechanism connects the claims to a specific tub. Probes of the common URL patterns (/pages/coa, /pages/lab-results, /pages/testing, /pages/quality, and equivalents) all return 404; the crawler's site-search queries for 'COA,' 'testing,' and 'lab' surfaced no additional pages; and the help center's four categories contain no testing or quality articles. The NASC certification statement is the one externally auditable quality signal, and it attaches to the company's quality system rather than to retrievable product test results.The program stops one layer above buyer verification: no named laboratory, no published COA, no lot-level lookup anywhere on the brand surface. Naming the third-party labs and posting even representative batch COAs would lift the score to the 5–8 band; a lot-linked lookup would be required for 9–10.Every formula undergoes independent third-party testing to confirm purity, potency, and label accuracy, ensuring the highest quality in every batch.The quality system is named; the facilities are not. The About page states 'PetLabCo.® is NASC Certified, the gold standard in independent quality and safety certifications' and that products 'are manufactured in facilities that follow NASC, FDA, and cGMP guidelines, meeting the highest U.S. pet supplement standards.' A sitewide banner on every product page reads 'Manufactured In The USA from domestic & globally sourced ingredients,' and the About page locates formulation in the USA. Sourcing logic is partially disclosed: ingredients are 'vetted for potency and bioavailability, which means we analyze how and where ingredients are sourced and processed'; Green-Lipped Mussel is identified as New Zealand-sourced and non-heat-treated; and branded inputs carry supplier attribution on the label panels (AstaReal — Fuji Chemical Industries; Enzalox — Lallemand). Facility identity stays at country level: no facility name, city, or state appears anywhere in the reviewed surface, FDA status is framed as guideline adherence rather than explicit facility registration, and HACCP, SQF, and ISO are not referenced.Disclosure matches the 8 anchor exactly: quality system named (NASC, cGMP, FDA guidelines) with facility identity held at country level. Naming co-manufacturing facilities at city/state level and stating FDA registration status explicitly would justify 9–10.As an NASC-certified company, we ensure our products are manufactured in facilities that follow NASC, FDA, and cGMP guidelines, meeting the highest U.S. pet supplement standards.The claim apparatus is dense and mostly disciplined. The home hero qualifies its lead claim inline — 'Our Advanced Dental Powder is clinically studied to reduce a bad breath-causing compound†' — with the dagger resolving on-page to the 28-day study description. Superlatives are footnoted to their actual basis ('America's #1 selling probiotic chew' resolves to 'YTD 2024 (as of Oct 31, 2024): PetLabCo.® PBC is #1 dog digestive remedy on Amazon'); results statistics are labeled as internal subscriber surveys with dates and sample sizes; product copy stays in structure-function register ('supports,' 'helps maintain,' 'occasional joint stiffness,' 'seasonal allergies') above a sitewide FDA disclaimer; and awards are footnoted to the granting body. Overshoot sits at the edges: the trademarked superlative 'Your Most Trusted Pet Health Optimization Partner™,' the unfalsifiable 'Just the science. No hyperbole. No unsupported health claims,' 'world's first clinically studied probiotic soft chews,' and learn-section article titles such as '7 simple hacks to end dog joint pain fast' and '8 natural ingredients proven to reduce joint pain' that run ahead of the structure-function discipline of the store pages. The post-purchase Getting Results page also repeats the 90-day study claim in prose without the PDP's footnote apparatus.Learn-section headlines with treatment-strength phrasing, unfalsifiable trust superlatives, and footnote-free claim repetition on post-purchase pages sit alongside otherwise well-qualified commerce surfaces. Bringing editorial titles and secondary marketing pages into the same qualified register as the PDPs would support a 9.Our Advanced Dental Powder is clinically studied to reduce a bad breath-causing compoundThe About item in primary navigation expands to clearly titled destinations — Our Story (quality and testing commitments), Experts (the named advisory board), and Ingredients (the glossary) — putting three of the four evidence pillars within two clicks of the home page. PDPs carry anchor menus ('Vet Reviewed | Key Ingredients | Directions for Use | Product Benefits') that put dose panels, expert attribution, and footnoted claims one click deep from any product tile, and the home-page FAQ surfaces expert names and clinical-study scoping without any navigation at all. The Probiotic Chew finished-formula study does have a destination — a learn-section article documenting the study and its named author — but that article sits in the learn library rather than being linked from the Probiotic Chew PDP or primary navigation. What primary navigation still cannot reach is the testing artifact layer: there is no testing or COA page at any probed URL, the help center's four categories are commerce-only (subscriptions, shipping, returns, product usage), and manufacturing and testing evidence exist only as sections within the Our Story page rather than as dedicated linkable surfaces.The testing pillar has no destination page, and the one published clinical study is reachable only deep in the learn library rather than linked from the product page or primary navigation. A consolidated trust hub linking study documents, laboratory identity, and COAs from primary navigation would push toward 9–10.We believe informed pet parents make the best decisions.

The brand uses "clinically tested," "clinically proven," "study-backed," or trial-adjacent language without surfacing finished-formula or properly qualified ingredient-level evidence.
What's in it
- Full per-active milligram disclosure with no proprietary blends across both current SKUs — The One names all twelve actives with amounts and inactives, and Soothe names all five.
- Public ingredient-evidence catalog citing studies with author lists, journals, years, study-design flags, and working links, each labelled as a dog, human, or review study.
- One fully credentialed named expert, Dr. Jamie Peyton (DVM, DACVECC, CVA, CVC, CCRT), surfaced as Chief Science Officer with a dedicated bio page and verifiable qualifications.
What's not in it
- No finished-product testing transparency: no named laboratory, no certificate of analysis, and no lot- or batch-level lookup — only an unquantified 'under the microscope eight separate times' claim.
- Manufacturing is disclosed only as 'Made in the USA'; the facility is not named at facility/city/state level and no facility certification (NASC, cGMP, HACCP, FDA registration, SQF, ISO) is published.

Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsDisclosure is near-complete and consistent across the current supplement line, which comprises two SKUs. The One publishes a 'Typical values per scoop' panel naming all twelve actives with per-active milligram amounts (krill 575mg, SunFiber guar gum 525mg, glucosamine 250mg, chondroitin 100mg, OptiMSM 100mg, taurine 100mg, curcumin phytosome 60mg, L-carnitine 50mg, BPL1 postbiotic 25mg, green tea extract 40mg, Sensoril ashwagandha 30mg, Suntheanine L-theanine 25mg), with serving size (~2g/scoop), a weight-based serving guide, a macronutrient table, and a named inactive-ingredients line. Soothe similarly discloses all five actives with per-active mg (MEG-3 fish oil 580mg, TruMune 250mg, Epicor 100mg, BiovaPlex egg membrane 50mg, Floradapt L. sakei 20mg). There are no proprietary blends and no grouped amounts anywhere in the line, and branded raw-material identifiers are named for nearly every active.Two details hold this just below a clean 10: amounts are presented as 'typical values per scoop' rather than guaranteed label minimums with %DV in a formal Supplement Facts format, and Soothe's panel does not surface a separate inactive-ingredients line the way The One does. Publishing guaranteed minimums and a parallel inactives line on Soothe would close the gap.Certified organic brown kelp (Ascophyllum nodosum), sea buckthorn (Hippophae rhamnoides [fruit]), silicon dioxide mineral source [stabilizer/carrier for L-carnitine].The brand publishes ingredient rationale for both products and an explicit five-pillar selection framework on the Ingredients page (Clinically Proven, Pharma Purity, Canine-Centric, Consistency, Human-Grade), and groups actives by the body system they target (Active Body, Healthy Gut, Balanced Mind). Each active carries a short mechanism or role statement — for example, curcumin is described as operating 'as an antioxidant, defending against cellular damage and blocking the enzymes that cause inflammation', L-theanine as triggering serotonin and dopamine while 'stimulating calming alpha waves in the brain', and SunFiber as fermenting 'into short-chain fatty acids that help to cultivate good bacteria in the gut'. Most meaningful actives therefore have a stated biological role, and the Ingredients hub adds supplier-grade and absorption rationale per ingredient. Mechanism depth is uneven, however: several blurbs (ashwagandha, taurine) read closer to benefit lists than to mechanism, and each role statement is a single sentence.The rationale is broad rather than deep — one sentence per active, with some actives described in benefit language rather than mechanism, and no criterion-by-criterion mechanism write-up tied inline to the cited study for every ingredient. Expanding each active to a fuller mechanism paragraph and linking it directly to its citation would lift this toward 9-10.Curcumin operates as an antioxidant, defending against cellular damage and blocking the enzymes that cause inflammation in the body.Citation infrastructure is a genuine strength. The /ingredients/evidence catalog presents 11 representative studies, each with title, full author list, journal, year, participant count, study-design flags (randomised / placebo-controlled / double-blind), and a working external link to PubMed, PMC, ScienceDirect, BioMed Central, ResearchGate, or CiteSeerX. Crucially, every study is labelled 'Dog', 'Human', or 'Review', so a buyer can immediately see that, for example, the L-carnitine and krill findings come from canine studies (56 Labradors; Iditarod sled dogs) while the chondroitin, MSM, and ashwagandha findings come from human trials. The limitation is the ingredient-versus-formula distinction: all cited studies are ingredient-level, none is on the finished 'The One' or 'Soothe' formula, and the page does not state that no finished-formula trial exists. The marketing surface then carries that ingredient evidence into formula-level claims — the home hero says ingredients are 'clinically proven to elevate your dog's whole-body health' and the PDP advertises '12 advanced ingredients with proven benefits in 400+ studies' under a 'Clinical Proof' header — without an inline qualifier that the proof is ingredient-level.What holds this below 9-10 is that ingredient-level studies are presented in a finished-formula context on the home and product pages without explicit qualification, and the brand does not state openly that no study exists on the finished formula. Adding an above-the-fold qualifier that 'clinically proven' refers to ingredients, and a plain note that finished-formula trials have not been conducted, would move this up.Our experts have assembled a catalog of 466 research publications verifying the health claims of our ingredientsThe brand surfaces one fully credentialed named expert: Dr. Jamie Peyton, DVM, DACVECC, CVA, CVC, CCRT, identified as 'Chief Science Officer & Science Advisory Board Chair'. She is named with full post-nominals and a quote on the home page and the Ingredients page, and has a dedicated bio page listing her UC Davis emergency/critical-care residency, her ACVECC mentorship at Four Seasons Animal Hospital, and her 2019 UC Davis Chancellor's Innovation Award. This is substantive, verifiable veterinary disclosure rather than a placeholder. Two factors temper it: the expert is not reachable from primary navigation (there is no Experts or Team link; the dedicated page is found via a /experts redirect), and the About page — the natural team destination — describes only 'A team of vets, biochemists and dog lovers' without naming anyone. The 'Science Advisory Board' that Dr. Peyton chairs lists no other members anywhere on the site.The score is held below 9-10 because the named expert is not surfaced from primary navigation and the About page anonymizes the team, and because the referenced advisory board has no other named members or roster. Linking the expert from the main nav, naming the rest of the board with credentials, and articulating each person's specific role would raise this.Chief Science Officer & Science Advisory Board ChairFinished-product testing is asserted but not substantiated for buyers. The strongest statement is on the /info product pages: 'By putting all of our ingredients under the microscope not once, not twice, but eight separate times…' — an unquantified quality-control claim. No third-party laboratory is named anywhere on the site, no certificate of analysis or potency report is published, and there is no lot- or batch-level lookup tied to a specific bottle. Probing returned 404 for /testing, /quality, /lab-results, /third-party-testing, /coa, and /certificate-of-analysis, and a cross-page scan found no contaminant or microbial panel and no facility testing detail; the only GMP reference on the site belongs to the OptiMSM raw-material supplier, not to FOTP's finished products. The home-page badges ('Pesticide-free', 'Non-GMO') are unsourced brand statements rather than published test results.The brand asserts testing but names no laboratory, surfaces no COA, and connects no testing to specific batches, which caps it at this tier. Publishing finished-product COAs with a named lab, a contaminant/microbial/potency panel, and a lot-linked lookup would move this up several tiers.By putting all of our ingredients under the microscope not once, not twice, but eight separate times, we're hoping to raise the standards of quality control on the pet supplement industry. Once and for all.Manufacturing disclosure is limited to a single element — a 'Made in the USA' badge in the home-page strip — with no facility named at facility/city/state level and no facility-level certification body cited (no NASC seal, cGMP, HACCP, FDA-registration, SQF, or ISO statement appears anywhere on the site). The brand does disclose meaningful ingredient sourcing on the Ingredients page: per-ingredient country of origin (krill from Norway, glucosamine and chondroitin from Spain, curcumin from Italy, several actives from India and Japan) plus supplier-grade rationale such as krill being 'The only MSC (Marine Stewardship Council) certified krill in the world, guaranteeing sustainable harvesting and traceability from the exact catch location'. The Sustainability page, which might host quality-system detail, is packaging-only. So sourcing logic is real at the ingredient level while the assembly facility and its quality system remain undisclosed.The facility is not identified and no facility-level quality system (NASC, cGMP, HACCP, FDA registration, SQF, ISO) is disclosed, which holds the score at the single-element tier despite strong ingredient-sourcing detail. Naming the manufacturing facility and its certifications would lift this to 8 and above.The only MSC (Marine Stewardship Council) certified krill in the world, guaranteeing sustainable harvesting and traceability from the exact catch locationThe brand avoids disease-treatment and cure language, and its clinical-style claims are backed by a real, publicly linked ingredient-evidence catalog rather than resting on unsupported assertion — meaningful discipline that keeps it well clear of the lower tiers. The mix is uneven, though, on formula-level certainty. The home hero states ingredients are 'clinically proven to elevate your dog's whole-body health', the PDP advertises '12 advanced ingredients with proven benefits in 400+ studies' under a 'Clinical Proof' header, and the site promises 'Real Results: Visible improvements within 6 weeks, or it's on us'. Because the underlying evidence is ingredient-level and no finished-formula trial is disclosed, this formula-level 'clinically proven / Clinical Proof' framing recurs across the home and product surfaces without an inline qualifier. The hero's specific wording — 'ingredients clinically proven' — is a partial qualifier, but the broader pattern asserts whole-product proof the brand's evidence supports only at the ingredient level.Recurring formula-level 'clinically proven' / 'Clinical Proof' language and a results guarantee outrun an ingredient-level evidence base, which holds the score at the mixed tier. Qualifying clinical claims as ingredient-level above the fold, and softening whole-product certainty where no finished-formula trial exists, would raise it.Try The One (and only) supplement with ingredients clinically proven to elevate your dog's whole-body health.Of the four trust pillars, the science pillar is the most navigable: 'Ingredients' sits in the primary navigation, and the full evidence catalog with authors, journals, and study links is one step further at /ingredients/evidence — genuinely strong, inspectable, pre-purchase evidence. The other pillars are harder to reach or thin. The named expert, Dr. Jamie Peyton, is quoted on the home and Ingredients pages but her credentialed bio page is not linked from primary navigation and the About page anonymizes the team. Testing has no destination page (only the unquantified 'eight separate times' line buried on the /info product pages), and manufacturing is a single home-page badge — so two pillars cannot be inspected in three clicks. There is no consolidated trust hub tying science, testing, experts, and manufacturing together.Science is easy to reach, but the expert page is outside primary navigation, the About page is anonymous, and testing and manufacturing lack any findable destination, so a buyer cannot inspect all four pillars in three clicks. A consolidated trust hub plus nav links to the expert and a testing page would raise this.Most dog supplements rely on generic ingredients and anecdotal claims. We're taking the opposite approach, to guarantee that all of our ingredients are backed by verifiable research publications.Reviewed Jun 13, 2026Sources: 12 sources reviewed4FOTFront of the PackDJP Ventures LLC (operating as Front of the Pack)Front of the Pack pairs full per-active mg labeling on both supplements with an unusually well-cited ingredient-evidence catalog and a named, credentialed Chief Science Officer....Borrowed Evidence72.5/100Solid With Gaps - 5RankVS

Williston, VT72.5/100as of 2026-06-13Solid With GapsVetriScience presents above the category median on label disclosure and manufacturing identity: full Product Facts images on every PDP reviewed, an owned SQF-certified FDA-registered Vermont operation, and founding NASC membership. Its clinical posture is distinctive — four finished-product studies described in methodological detail — but the storefront does not link them; the full write-ups (named investigators, and a companion analysis published in the Journal of Medical Science, 2008) live in a separate brand library that is not linked from the consumer surface and currently behind an expired certificate. The remaining gaps are artifact-level: no named testing laboratory, no public COA or lot lookup, and no named formulator behind the line's vet-formulated identity.
Public Evidence System Named Vet ReviewerIngredient RationaleDisease-Claim-FreeNASC Member Finished-Formula Trial Named Mfg FacilityWhat's in it
- Complete back-of-pack Product Facts panels are published as gallery images on every PDP reviewed, quantifying every active in mg/IU/CFU — including strain-level probiotic identification (Bacillus coagulans GBI-30, 6086) and a 28-line senior multivitamin panel.
- Finished-product clinical work is described with real methodological detail — a randomized double-blind crossover study at Washington State University, two CanCog Technologies calming studies, and a 20-dog VOHC-scored dental trial — rather than borrowed ingredient research.
- Manufacturing disclosure pairs facility ownership with named regimes: products are made in the brand's own SQF-certified, FDA-registered Vermont facilities under cGMP, with founding membership in NASC documented on a dedicated page.
What's not in it
- The four clinical studies are described on the storefront with no inline citation or link; the full write-ups — with named investigators, and a companion analysis published in the Journal of Medical Science (2008) — sit in a separate info.vetriscience.com white-paper library that is not linked from the consumer surface and currently behind an expired security certificate, so a buyer cannot reach a citable study from the site.
- No certificate-of-analysis access exists at any depth — no named third-party laboratory, no lot-level lookup, and no disclosed contaminant or microbial panel scope, with eleven probed COA-style URLs returning 404.
- 'Vet Formulated. Pet Approved.' appears on every label, but no formulator is named; the credentialed veterinarians on the VetriExperts page are surfaced as consultants and ambassadors, not as the people who designed the formulas.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsEvery PDP reviewed publishes the complete back-of-pack Product Facts panel as a full-resolution gallery image, and the disclosure standard holds from flagship chews to legacy capsules. Calm & Confident discloses Thiamine 134 mg, Colostrum Calming Complex Biopeptide Blend 22 mg, and L-Theanine 21 mg per chew with a complete inactive list; Extra Strength Healthy Hip & Joint quantifies all ten actives per 2 chews down to Selenium 0.002 mg; Senior 27+ Active Health quantifies roughly 28 actives line-by-line; and Gut Health names its probiotic at strain level (Bacillus coagulans GBI-30, 6086) with 1,000,000,000 CFU per chew. PDP body text, however, repeats only headline doses (the joint line's '1000 mg of glucosamine, 1000 mg of MSM, and 600 mg of green-lipped mussel per 2 chews') or none at all, so per-active amounts on most SKUs live solely in the label photograph rather than machine-readable page text. Two blend-level items hold the line below full disclosure: the flagship calming active is a patented branded blend disclosed at 22 mg total without protein-fraction breakdown, and the legacy Healthy Gut & Digestion capsule carries a 'Proprietary blend 13 mg' covering Lactobacillus acidophilus (no CFU), bromelain, and papain. Serving sizes and weight-banded dosing tables are defined on every label reviewed.One reviewed legacy SKU uses an unquantified proprietary blend (13 mg across three components, probiotic without CFU), and per-active panels exist only as label images rather than structured on-page text. Publishing the full panel as page text on every PDP and breaking out (or CFU-quantifying) the remaining blend components would support a 9-10.is formulated with 1000 mg of glucosamine, 1000 mg of MSM, and 600 mg of green-lipped mussel per 2 chewsEach PDP reviewed carries an 'Ingredient Highlights' section that explains actives in mechanism language rather than benefit assertion alone, and the pattern holds across flagship and secondary SKUs. Calm & Confident explains that L-theanine 'supports calm behavior and relaxation through the production of serotonin and dopamine' and that thiamine supports nervous-system function; the joint line explains MSM as a sulfur compound supporting 'collagen synthesis,' manganese as supporting collagen formation, and green-lipped mussel as a whole-food source of glucosamine, hyaluronic acid, and omega-3s; Lysine Immunity Health explains lysine's role in antibody production and DMG's role in oxygen utilization and lymphocyte production. Selection logic occasionally goes a level deeper — the joint PDP explains the brand 'uses only the highest quality forms of glucosamine from sources like shrimp & crab' versus synthetic alternatives. The rationale is uncited: phrases like 'heavily researched' and 'Research suggests' appear with no ingredient-level study links anywhere on the surface (no PubMed citations were detected site-wide), and educational hub pages (Why Supplements?, Understanding Pet Stress) list ingredient categories without mechanism content. Some entries also stay at benefit level, such as grape seed extract as 'another powerful antioxidant.'Mechanism content is consistent but never cited — 'heavily researched' and 'Research suggests' assertions carry no ingredient-level references a buyer can open. Adding citations to the existing Ingredient Highlights, and extending mechanism content to the educational hub pages, would support a 9-10.Colostrum Calming Complex® is a patented biopeptide blend of colostrum proteins. These proteins are heavily researched and have been found to have a calming effect on animals, reduce stress, and support cognitive function.VetriScience's clinical evidence is unusually finished-formula for the category: the Backed by Science page describes four studies on the products themselves rather than borrowed ingredient research — a 'randomized, double-blind, cross over design dog study at Washington State University' on Healthy Hip & Joint using an osteoarthritis model with peak-vertical-force and synovial PGE2 endpoints, two blind repeated-measures CanCog Technologies studies on Calm & Confident (onset within 30 minutes) and Long Lasting Calm & Confident (effects at 8 hours), and a double-blinded 20-Greyhound dental trial scored to VOHC criteria reporting 'reduction in overall plaque by 20% and calculus by 18%.' The summaries name institutions and quantify outcomes, and the About Us page states the brand 'continue[s] to underwrite university studies.' On the consumer storefront, none of these summaries links to a citation or full-text document — the /research page and the product pages making the claims carry no authors, journals, DOIs, or study links inline. The brand does, however, publish full study write-ups in a separate library at info.vetriscience.com (e.g., the Glyco FLEX 3 / Healthy Hip & Joint white papers, which name the Washington State University investigators — Martinez, McCormick, Powers, Davies, Yanez, Hughes, Lincoln — and note a companion canine-chondrocyte analysis 'published in Journal of Medical Science, 2008'); that library is not linked from the storefront or primary navigation, aThe brand's storefront does not surface the studies it actually has: full write-ups — with named investigators, and a companion canine-chondrocyte analysis published in the Journal of Medical Science (2008) — exist in a separate info.vetriscience.com white-paper library that is not linked from the research page or product claims and currently sits behind an expired security certificate, while on-surface coverage is limited to three product families. Linking the existing study white papers from the research page and the claims that depend on them, restoring a valid certificate on the library host, citing author/journal detail inline, and stating which products carry no finished-formula study would lift this to 8+.Healthy Hip & Joint was used in a randomized, double-blind, cross over design dog study at Washington State University.The VetriExperts page sits in primary navigation and names six people, four of them veterinarians with stated credentials: Dr. Elizabeth DeLomba (DVM Michigan State, MBA Villanova, 16 years clinical practice, 14 years veterinary pharmacy) is identified as the brand's Senior Veterinary Services Consultant and anchors a 'Veterinarian Approved' section on the research page; Drs. Dela Cruz (Purdue), Sheehan (Ohio State 2004, owner of four integrative hospitals), and Tarantino (senior-pet practice) are profiled with schools, practice histories, and locations. The disclosure gap is scope: the page frames these experts as customer-facing voices who 'help VetriScience by giving perspective to our customers from their point of view,' while the brand's central claims — 'Vet Formulated. Pet Approved.' on every label and 'Formulated by vets' on the Pet's Sake Promise page — are never connected to a named individual. The Quality page attributes formulation to anonymous 'Scientists and veterinarians [who] work together,' and the corporate site references unnamed 'Scientific Review Boards.' A buyer can verify who consults and endorses, but not who formulates.Named, credentialed veterinarians are surfaced from primary navigation, but none is identified as a formulator, and the 'Vet Formulated' label claim remains anonymous. Naming the formulating veterinarian(s) or scientific review board members with role descriptions would support a 9-10.Our VetriExperts are trusted specialists in their fields. They help VetriScience by giving perspective to our customers from their point of view!Testing is asserted at several specific points on the surface: the Quality page states 'Each ingredient undergoes third-party testing for purity and composition' and that 'best-in-class label testing means that what's listed on the label is what's in every bag or bottle' (a potency/label-claim verification statement); the FAQ repeats that 'All of our ingredients are third-party tested'; and the NASC Quality Seal page documents enrollment in a program requiring members to 'Submit to random product testing by an independent lab to ensure ingredients meet label claim' plus adverse-event reporting and audited SOPs. These are line-wide program claims with an externally checkable anchor (NASC founding membership, seal printed on every reviewed label). What is not published: no testing laboratory is named anywhere, no certificate of analysis is viewable or requestable through any surfaced channel, no lot-level lookup exists (eleven probed URL patterns return 404 and site search returns no results), and no contaminant or microbial panel scope is described. The buyer can verify that a testing program is claimed and NASC-anchored, but cannot inspect a single result.No named laboratory, no public COA, no lot-level traceability, and no disclosed panel scope — testing claims stop at program description. Naming the third-party labs and publishing even representative COAs would reach 7-8; a lot-linked lookup across the line would be required for 9-10.Each ingredient undergoes third-party testing for purity and composition to ensure it meets our strict standards for quality. Our best-in-class label testing means that what’s listed on the label is what’s in every bag or bottle.The quality system is one of the better-documented in the vet-channel cohort: the home page states 'We manufacture our products in our own Safe Quality Food (SQF) Certified and FDA-registered facility' — facility ownership plus two named certification regimes — and the Quality page adds cGMP adherence, routine audits, and AAFCO/NASC formulation standards. The FAQ consolidates it: 'Our manufacturing facilities are SQF-certified and strictly adhere to NASC guidelines and Current Good Manufacturing Practices (cGMP) as defined by the Food and Drug Administration.' Facility identity is held at state level — 'VetriScience® has developed and manufactured pet health supplements from our facilities in Vermont' — while the Williston, VT address appears on labels only as the distributor line, so no page explicitly names the manufacturing plant at facility/city level. Sourcing logic is partially disclosed: ingredients are 'sourced globally, with many coming from the U.S.,' suppliers 'must undergo a rigorous application process,' and marquee ingredients carry origin detail (GlycOmega green-lipped mussel from New Zealand; glucosamine from shrimp and crab). HACCP, ISO, and SQF certificate numbers or audit summaries are not published.Facility identity stops at 'our facilities in Vermont' — the manufacturing plant is not explicitly named at facility/city/state level, and certification artifacts (SQF certificate, audit grade) are not published. Explicitly identifying the Williston facility as the manufacturing site and surfacing certificate-level detail would support a 9-10.We manufacture our products in our own Safe Quality Food (SQF) Certified and FDA-registered facility.The brand's clinical-style claims are quantified, product-scoped, and traceable to described studies: 'Clinically tested to increase hind leg strength by 41% in just four weeks,' 'Clinically shown to work within 30 minutes,' and 'Clinically tested to reduce plaque and tartar within 28 days' each map to a specific study summary on the research page, and that page uses appropriately hedged language ('results of the study suggest that Healthy Hip & Joint may help normalize joint function'). No disease-treatment language was observed across the reviewed surface; structure/function phrasing ('supports,' 'promotes') dominates, and labels carry NASC-required cautions. Discipline loosens at the edges: hero and PDP framing presents study findings as unqualified outcomes ('Increase hind leg strength in just four weeks.') with no inline qualifier or citation link; the home page makes a market-superiority claim ('some of the only clinically tested pet supplements on the market' — softened by 'some of' but not sourced); and the Why Supplements? page asserts a longevity-and-cost benefit no cited evidence supports. The pattern is disciplined at the core with isolated overshoots on educational and hero surfaces.Above-the-fold claims run unqualified ('Works in just 30 minutes') without inline citations, and the Why Supplements? longevity/cost-avoidance framing exceeds any evidence the brand publishes. Inline qualifiers linking hero claims to the study summaries, and removing or evidencing the longevity language, would support a 9-10.Not only will they keep your pet by your side longer, but they will keep your pet healthy so that you can avoid expensive veterinary care visits.The 'Why VetriScience' primary-nav menu functions as a near-consolidated trust hub: About Us, Pet's Sake Promise, NASC Quality Seal, 100% Guarantee, Quality Story, VetriExperts, and Backed by Science (with four product-research anchors) are each one click from any page, with plainly descriptive titles, and a 'Healthy Pets' menu carries the educational pages and FAQ. Science summaries, named experts, and manufacturing/quality disclosures are therefore all reachable in two clicks from home. Two frictions hold the surface back from the top tier. First, per-active dose panels are published only as back-of-pack photographs inside PDP image galleries — a buyer must open a product page and flip through eight to ten gallery images to find the 'Product facts' photo, and on-page text rarely repeats the amounts. Second, testing claims never resolve to an inspectable artifact at any click depth: there is no COA, lab name, or lot-lookup destination anywhere on the site, confirmed by URL probing and site search. There is no single trust-hub landing page; the evidence is distributed across roughly seven nav destinations.Dose panels require flipping through PDP gallery photos rather than reading page text, and the testing pillar has no artifact destination at any depth. A consolidated trust hub linking research, label panels, and testing documentation would support a 9-10.Clinical studies exemplify what veterinarians have said about VetriScience® since we began making supplements.Reviewed Jun 13, 2026Sources: 20 sources reviewed5VSVetriScience LaboratoriesFoodScience, LLCVetriScience presents above the category median on label disclosure and manufacturing identity: full Product Facts images on every PDP reviewed, an owned SQF-certified FDA-regis...72.5/100Solid With Gaps - 6RankPH

The gaps cluster on verification artifacts — no COA access or named laboratory, citations confined to joint ingredients on an unlinked Sources page, an empty Our Research page, and a comparative 'Real Results' campaign that outruns the published evidence base.

- Six named experts with disclosed credentials — including a DACVIM board-certified internist and an in-house PhD Chief Scientific Officer whose formulator role is corroborated on three separate pages — reachable from primary navigation.
- Standardized numeric Guaranteed Analysis / Active Ingredients panels with per-active mg, IU, and CFU amounts on every reviewed product across chews, powders, oils, and the cat line.
- Quality-system disclosure names five distinct elements in one FAQ answer — U.S.A. manufacture, GMP certification, FDA registration, SQF, APHIS — plus the NASC quality seal.
What's not in it
- No public COA library, lot lookup, or named third-party laboratory exists anywhere on the site; testing language stays at 'rigorously tested' with one unattributed '3rd party tested' card on the fish oil page.
- Published citations cover only joint/mobility ingredients, the Sources and References page is not linked from any navigation surface, and the page titled 'Our Research' carries no content at review time.
- Manufacturing facility identity is held at country level ('made in the U.S.A.') with no facility name, city, or state, and Allergy Support's seven-mushroom proprietary blend discloses a 100 mg total without per-species amounts.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsNumeric disclosure is standardized across the line: all eight PDPs reviewed (Multivitamin 10-in-1, Hemp Calming, Allergy Support, Hip + Joint Health, Probiotics Powder, Dental Powder, Omega-3 Fish Oil, Cat Dual Texture Multivitamin) publish a 'Clean Ingredients' gallery image carrying a Guaranteed Analysis or Active Ingredients panel with per-active amounts and a defined serving basis — per 2 chews (6 g), per scoop (2.5 g), per teaspoon (5 mL), or per 10 cat chews (3 g). Hip + Joint discloses every active individually (Glucosamine HCl 625 mg, Turmeric 500 mg, MSM 325 mg, Chondroitin 180 mg); Hemp Calming lists ten actives from Valerian Root 200 mg down to Magnesium Citrate 5 mg; the fish oil quantifies EPA 480 mg and DHA 300 mg per teaspoon; inactive lists are published as companion images. The exceptions are class-level groupings: Allergy Support carries the line's one literally-labeled 'Proprietary Mushroom Blend 100 mg' spanning seven named mushrooms without per-species amounts, Dental Powder groups a two-ingredient 'Fresh Breath Blend' at 100 mg, probiotics are disclosed as total CFU with species named but not per-strain counts, and Probiotics Powder groups 'Total Enzymes 80 mg' across seven enzymes. A buyer should also note the numeric panels live in PDP image carousels — the on-page text accordions repeat ingredient names without amounts.The Allergy Support mushroom blend (100 mg across seven mushrooms) and the grouped probiotic CFU and enzyme totals hold the line below tier 9, which requires blend ambiguity confined to secondary ingredients on at most one or two products. Publishing per-species mushroom amounts, per-strain CFU, and mirroring the numeric panels in on-page text rather than gallery images only would lift the score.These soft chew supplement treats contain the proper (and research-backed) amounts of:Mechanism content is real but unevenly distributed. The FAQ's 'How do the ingredients in your mobility products work?' module explains eight joint actives role-by-role — chondroitin as 'a component of connective tissues found in cartilage and bone', vitamin C as stimulating 'the production of collagen and glycosaminoglycans', glucosamine HCl as a 30% more concentrated form absorbed to support cushioning, and green-lipped mussels as a source of EPA, DHA, and ETA. PDP 'How It Works' sections carry partial mechanism for other lines: the Multivitamin page connects probiotics and pumpkin to gut flora and notes 'about 70% of immune response lies in the digestive system', and Allergy Support explains colostrum as 'a natural pre-milk protein-rich compound which contains antibodies and white blood cells' tied to histamine response. The Pure Vitality Blend page assigns roles to each base ingredient (oats for fiber, protein, and B-vitamins; brewer's yeast for prebiotics). Hemp Calming, by contrast, stays in benefit language — actives 'work together to curb your dog's anxious behavior by creating a calming effect' — and no central ingredient encyclopedia connects every active across the line to a stated role.Mechanism depth is concentrated on the mobility line; calming and several other categories rely on benefit assertions, and rationale is split across the FAQ, PDP accordions, and two standalone pages rather than a per-ingredient reference a buyer can consult. A line-wide ingredient glossary with stated biological roles would lift this to an 8.Chondroitin is a component of connective tissues found in cartilage and bone.Citation work exists and is honestly framed where it appears, but it is narrow and poorly surfaced. The FAQ lists five author-and-journal citations for joint ingredients (Neil/Caron/Orth in JAVMA 2005, McCarthy et al. in The Veterinary Journal 2007, Kim et al. 2006 on MSM, Funk et al. on turmeric, Teare et al. 1979 on ascorbic acid) under wording that correctly attributes the evidence to ingredients rather than the finished formula: 'The efficacy of the ingredients in these products is also supported by clinical research and studies'. A standalone Sources and References page publishes ten numbered citations with live NCBI/PubMed links — all ingredient-level and all joint-focused — but is not linked from navigation, the footer, the FAQ, or any reviewed PDP. No 'clinically proven' or 'clinically tested' phrasing was found anywhere on the reviewed surface. Finished-product evidence is limited to a brand-run 2022 in-home study cited by footnote ('84% of pet parents noticed a difference...*Based on in home study conducted by Pet Honesty in 2022') with no published methodology, and the page titled 'Our Research' resolves with no content at review time.Citations cover only the joint/mobility ingredient set, the Sources page is unreachable from any navigation surface, the 2022 in-home study has no published methodology, and the brand does not state explicitly that no finished-formula clinical study exists. Linking the Sources page from PDPs, extending citations beyond the joint line, and publishing the in-home study design would lift the score toward 8.The efficacy of the ingredients in these products is also supported by clinical research and studies:PetHonesty publishes one of the stronger named-expert surfaces in the DTC pet supplement set. The Science & Health Advisory Council page (reachable from the Learn dropdown as 'Science & Health Advisory Council' / 'Our Scientific Advisors') names six experts with credentials and biographies: Dr. Adam Rudinsky, DVM, DACVIM (tenured Associate Professor, Ohio State University Veterinary Medical Center); Dr. Donald Ingram, PhD (former Chief of the Nutritional Neuroscience and Aging Laboratory at Pennington, 500+ publications); Dr. Geri Katz, VMD; Dr. Kevin Ragland, PhD (Associate Professor of Animal Science, MTSU); Dr. Vickie Carmella, DVM, FFCP; and Dr. Greg Reinhart, PhD, the in-house Chief Scientific Officer with 250+ papers and 14 U.S. patents. Reinhart's formulator role is corroborated on two other pages — 'Dr. Greg, the brains behind our award-winning supplements' (Ingredients & Safety) and 'handpicked by our in-house nutritionist, Dr. Greg' (Pure Vitality Blend) — making at least one expert fully surfaced with credentials, role, and scope. The five council members carry full credentials but only a collective scope statement: the council exists to 'help guide & strengthen Pet Honesty's science-first approach', without per-member descriptions of what each contributes to the products.Council members' individual scope of involvement is not itemized — bios describe careers, not duties for the brand — and the page sits behind a hover dropdown rather than a standing top-level link. Per-member role descriptions (who reviews what, for which product families) would complete the tier-10 requirement.our Science & Health Advisory Council brings together PhD scientists, leading researchers, & animal nutrition experts to help guide & strengthen Pet Honesty’s science-first approachTesting is asserted in several places but never documented. The FAQ states products are 'rigorously tested to ensure our products meet the highest quality standards' without naming a laboratory, a panel, or a document; the Omega-3 Fish Oil PDP carries a gallery card reading '3rd party tested for purity & transparency' — the only third-party-testing assertion found — again with no laboratory named and nothing linked. The NASC statement on Ingredients & Safety references 'testing' within the seal's scope ('labeling, testing, quality control, and production'), which is a program-level signal rather than product-level results. Lot numbers exist physically — the FAQ notes each jar carries a stamped Lot # and Best By date — but no public lot lookup, COA library, contaminant panel, microbial panel, or potency verification is published anywhere on the site: twelve probed URL patterns return 404, /pages/testing redirects to a testimonials page, and storefront search for 'certificate', 'lab', and 'third party tested' returns nothing.No named laboratory, no COA access, and no batch linkage holds this at tier 4.

The FAQ discloses five distinct elements in one answer: U.S.A. manufacture, GMP-certified facility, FDA registration, SQF (Safe Quality Food) certification, APHIS, and company-level NASC membership; Ingredients & Safety adds the NASC quality seal statement and 'Made in the USA with U.S. & Global Ingredients... USA-based, FDA- regulated facilities that go through multiple high quality checks'; the Hemp Calming PDP repeats 'Made in an American GMP-Certified facility'. Sourcing is disclosed in fragments rather than as a policy: the fish oil announces a transition to 'Marine Stewardship Council-certified Alaskan fisheries', the FAQ places green-lipped mussel sourcing 'from the waters near New Zealand', and a PDP accordion states 'We partner with trusted suppliers that meet FDA Regulations'. No facility name, city, or state is published anywhere on the reviewed surface, and no systematic ingredient-traceability documentation exists.Facility identity is held at country level — no facility name, city, or state — which is precisely what separates tier 8 from tier 9-10. Naming the manufacturing facility (or co-manufacturer) and consolidating the scattered sourcing statements into a documented sourcing policy would lift the score.All of our products are manufactured in the U.S.A. in a GMP (Good Manufacturing Processes) certified facility that is FDA registered. Our facilities have additional quality certifications like SQF (Safe Quality Food), NASC, and APHIS.The discipline baseline is genuinely solid: no 'clinically proven' or 'clinically tested' phrasing appears anywhere on the reviewed surface, product copy runs on structure/function verbs ('supports', 'helps maintain', 'promotes'), survey-based percentages carry inline footnotes ('*Based on in home study conducted by Pet Honesty in 2022', 'Based on a survey of Multivitamin subscribers'), and PDPs publish unusually detailed caution blocks (Hemp Calming warns against use with CNS depressants, MAO inhibitors, and before anesthesia). The overshoot is a recurring comparative campaign rather than an isolated page: 'Us vs Them' cards on PDPs award PetHonesty 'Real Results' while assigning unnamed competitors 'No Proven Results', and the home page repeats 'No signs of proven results' — a proven/not-proven distinction the published evidence base (brand-run in-home surveys without methodology) cannot fully carry. Adjacent flourishes include sitewide 'vet-approved' and 'vet-recommended' badging without inline attribution, the FAQ's 'About 80%-90% of our customers DO see positive results', and the MicroSilver grooming claim 'stopping itching, hot spots, & more in their tracks'.The comparative 'Real Results' / 'No Proven Results' framing recurs across PDPs and the home page without a cited basis, holding the brand below tier 8's 'isolated' threshold. Retiring or substantiating the comparative cards and anchoring 'vet-approved' to the named council inline would lift the score.84% of pet parents noticed a difference in their dog’s mobility after 4 weeks of taking Hip + Joint Health Max Strength.What the brand publishes is mostly reachable, but the four evidence pillars are split across surfaces of very different visibility. Named experts and the ingredient/quality story are the easy finds: the Learn dropdown in primary navigation carries 'Science & Health Advisory Council' and 'Our Ingredients', each one hover and one click from home. Manufacturing certifications and the ingredient-level citations live inside FAQ answers reached via the footer's 'Need Help?' link, requiring a buyer to open the right accordion questions. The dedicated Sources and References page — the brand's best citation asset — is linked from nothing and discoverable only by direct URL, and the page titled 'Our Research' loads without content. Per-active dose panels are published as PDP gallery images, so a buyer must flip through the product carousel rather than read them in page text. There is no consolidated trust hub, and the testing pillar has no destination at all: COA and laboratory probes return 404 and storefront search surfaces nothing.Citations sit on an orphaned page, manufacturing detail is footer-FAQ-only, and the testing pillar has no destination, leaving the buyer to assemble the picture from four differently-buried surfaces.

YuMOVE
Lintbells Ltd
United Kingdom68.5/100as of 2026-06-13Disclosure GapsYuMOVE discloses every active by dose across its joint line and footnotes its claims to named studies and surveys, including a finished-formula Royal Veterinary College trial that is summarized as data-on-file rather than a published, linked study. A named, credentialed veterinary and R&D team is published on the US surface, but only on a deep page that primary navigation does not link to. Remaining gaps cluster on testing and manufacturing identity: there is no named laboratory, no public COA or lot lookup, and manufacturing is disclosed only as 'made in the USA' without a facility name or quality-system certification.
Public Evidence System Named Vet ReviewerIngredient RationaleDisease-Claim-FreeNASC Member Finished-Formula Trial Named Mfg FacilityWorth NotingEvidence Buried
The brand technically publishes meaningful science, evidence, testing, or expert disclosure, but buyers cannot reach it without dedicated effort. Evidence that exists but is hard to find counts less.
What's in it
- The modal joint line publishes full per-active mg panels with no proprietary blend, from Glucosamine HCl 500mg and Green Lipped Mussel Powder 300mg on the Soft Chews to an eight-active panel on the PLUS tablets.
- A dedicated Research & Studies page distinguishes a finished-formula Royal Veterinary College RCT (40 dogs, double-blind, placebo-controlled crossover) from ingredient-level evidence and provides downloadable peer-reviewed papers for Green Lipped Mussel, N-acetyl-D-glucosamine, and Hyaluronic Acid.
- Marketing claims are consistently footnoted to named, dated sources and a non-disease disclaimer, with an Our Claims page mapping each headline statement to its survey or study.
What's not in it
- No public finished-product testing program: no named third-party laboratory, no contaminant, microbial, or potency panel for the finished product, and no certificate-of-analysis or lot-number lookup (probed COA and testing URLs return 404).
- The primary 'Our Story' page names only co-founder Dr. John Howie with no stated credentials; the named, credentialed veterinary and R&D roster (four of five holding MRCVS) appears only on The Lintbells Story page, which primary navigation and the footer do not link to, so a buyer reaches it only via on-site search or direct URL.
- Manufacturing is held at country level ('now manufactured in the USA using globally sourced ingredients') with no facility name, city, or state and no quality-system certification (NASC, cGMP, FDA-registration, HACCP, SQF, or ISO).
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsThe modal joint line discloses every active by name and amount with no proprietary blend. The Soft Chews PDP publishes 'Glucosamine HCI (from Corn Extract) 500mg, Green Lipped Mussel Powder (containing Chondroitin) 300mg, Vitamin C (Ascorbic Acid) 25mg, Manganese Sulfate Monohydrate 6mg, Hyaluronic Acid 3mg, Vitamin E (D-Alpha Tocopheryl Succinate) 1mg', with a scaled large/extra-large version. The PLUS / Advanced Vet Strength tablet panel is equally explicit per 0.96g tablet, adding N-Acetyl-D-Glucosamine 20mg and Omega-3 (Fish Powder) 1mg. Serving sizes are defined by dog weight in feeding tables. The one consistent ambiguity is that chondroitin and the GLM omega-3 are quantified only as components inside the 300mg / 180mg 'Green Lipped Mussel Powder (containing Chondroitin)' line rather than as standalone mg, so a buyer cannot read the exact chondroitin or omega-3 dose. The score reflects the joint line as the modal product; calming and dental SKUs were not panel-verified at the same tier.Two key bioactives — chondroitin and the GLM omega-3 fraction — are disclosed only as contents of the Green Lipped Mussel Powder line rather than as standalone per-active amounts, so the exact dose of each is not readable. Full active-by-active mg across every SKU including the calming and dental lines, with chondroitin and omega-3 broken out individually, would lift the score toward 9-10.Glucosamine HCI (from Corn Extract) 500mg, Green Lipped Mussel Powder (containing Chondroitin) 300mg, Vitamin C (Ascorbic Acid) 25mg, Manganese Sulfate Monohydrate 6mg, Hyaluronic Acid 3mg, Vitamin E (D-Alpha Tocopheryl Succinate) 1mg.For the joint flagship line the brand publishes a clear biological role for each active rather than benefit assertions alone. The Ingredients page is organized by function — Shock Absorption, Soft Tissue Support, Structural Support, Mobility Support — and states that 'Glucosamine provides basic building components of cartilage helping to maintain joint structure', that Hyaluronic Acid 'is a core component of joint fluid which helps to lubricate and cushion the joint', that Manganese 'supports collagen formation in the cartilage, tendon and ligaments', and that Vitamins C and E 'neutralize free radicals to help support joint mobility'. The ActivEase page adds a mechanism for Green Lipped Mussel, attributing its effect to Omega-3s 'supporting the normal inflammatory response', and the Research page provides ingredient-level studies for GLM, N-acetyl-D-glucosamine, and Hyaluronic Acid. The rationale is concise and role-based rather than a citation-per-active treatment, and it is concentrated on the joint line; calming and dental products were not given the same mechanism depth on the surface reviewed.Mechanism content is strong for the joint line but is concise role-language rather than a criterion-by-criterion explanation with an ingredient-level citation tied to each active, and it does not visibly extend to the calming and dental lines. Per-active mechanism plus a linked study for every meaningful ingredient across the full line would move the score toward 9-10.Glucosamine provides basic building components of cartilage helping to maintain joint structureYuMOVE does the structurally important work of separating finished-formula evidence from ingredient-level evidence. The Research & Studies page lists a 'complete joint supplement' study — a Royal Veterinary College UK randomized, double-blind, placebo-controlled crossover trial of 40 dogs — distinct from ingredient studies on Green Lipped Mussel, N-acetyl-D-glucosamine, and Hyaluronic Acid, and provides downloadable PDFs for all five. The ingredient PDFs are genuine peer-reviewed papers (Bierer & Bui, J Nutr 2002; Jerosch, Int J Rheumatology 2011; Eason et al, Vet Sci 2018). The page disclaims that conclusions are 'the observations of independent researchers and not as a claim made by YuMOVE or Vetnique'. The limiter is that the finished-formula RVC trial is presented as a one-page brand-authored summary marked '(Data on file)' rather than a linked published RCT, and the pervasive 'clinically proven to work in just 6 weeks' claim on PDPs points to 'the Royal Veterinary College' by name without a hyperlink to a readable study, so a buyer must locate the Research page to connect the claim to its source.The headline finished-formula proof rests on a 'Data on file' summary of the RVC trial rather than a publicly readable, peer-reviewed publication, and PDP claim footnotes name the study but do not link it. A published, accessible finished-formula RCT citation surfaced at the point of each 'clinically proven' claim would lift the score toward 9-10.We do not purport to cure, mitigate, treat, or prevent any disease. The conclusions reached in these studies are the observations of independent researchers and not as a claim made by YuMOVE or Vetnique.Named, credentialed experts are disclosed on the US surface, but only on a deep page rather than from primary navigation. The 'Our Story' page reached from the main nav names just co-founder Dr. John Howie — 'a dedicated nutritional scientist' — with no degree, institution, or veterinary qualification stated. A separate page on the same domain, The Lintbells Story, publishes the full Research & Development roster of YuMOVE's originator and manufacturer with credentials and roles: 'James Howie BVetMed MRCVS (Veterinary Director), Rachel Hylton BVetMed MRCVS (Veterinary Technical Manager), Siobhan Griffin RVN (Learning & Development Executive), Dr Ann Haigh MVB MSC MRCVS (Product Development Manager), Andrew Little VetMeD, MRCVS, MBA (Innovation Manager)'. Four of the five carry MRCVS (UK veterinary) credentials and two hold explicitly veterinary titles, so named veterinarians with credentials and roles are in fact present. What keeps the score at this tier rather than higher: the roster page is not linked from the primary navigation or footer of the home, About, or product pages reviewed (it surfaces via on-site search and direct URL), it documents titles rather than per-person scope or biography, and it is framed as the Lintbells R&D team rather than as the present-day US formulation staff, while the homepage still attributes the line to an anonymous 'team of veterinary experts and scientists'.The credentialed veterinary and R&D roster is published only on a deep page (The Lintbells Story) that is not reachable from primary navigation or the footer, gives titles rather than per-person scope or biography, and is framed as the originator's R&D team rather than current US formulation staff, while the primary 'Our Story' page names only the uncredentialed co-founder. Surfacing this named team with credentials, roles, and scope from primary navigation would move the score toward 9-10.James Howie BVetMed MRCVS (Veterinary Director) Rachel Hylton BVetMed MRCVS (Veterinary Technical Manager) Siobhan Griffin RVN (Learning & Development Executive) Dr Ann Haigh MVB MSC MRCVS (Product Development Manager) Andrew Little VetMeD, MRCVS, MBA (Innovation Manager)The brand publishes one specific testing-adjacent practice, but it operates at the ingredient level, not the finished product. The ActivEase page states 'we sample every batch of our GLM up to eight times in a day to ensure sufficient levels of over 40 different fatty acids' — a Green Lipped Mussel potency check, named to no laboratory. There is no finished-product third-party testing disclosure, no named lab, and no contaminant, microbial, or potency panel for the bottle a buyer would purchase. No certificate-of-analysis or lot-number lookup tool exists: probed URLs (/pages/testing, /pages/quality, /pages/coa, /pages/certificate-of-analysis, /pages/lab-results, /pages/third-party-testing) all return 404, the FAQ contains no testing question, and the crawler reports has_testing_page and has_coa_lookup both false. Lot-level traceability to a public lab report is not offered anywhere on the US surface.The only testing signal is ingredient-level GLM potency QC with no named lab; the finished product has no public contaminant, microbial, or potency panel, and no COA or lot-lookup exists (probed URLs 404). A named third-party lab plus a lot-linked finished-product COA covering the line would move the score from the lower band toward 7-10.we sample every batch of our GLM up to eight times in a day to ensure sufficient levels of over 40 different fatty acidsManufacturing disclosure consists of a single location element plus genuine ingredient-sourcing logic. The PLUS / Advanced Vet Strength PDP states the brand is 'now manufactured in the USA using globally sourced ingredients' — a country-level statement with no facility name, city, or state. Sourcing logic is disclosed for the signature ingredient: the ActivEase page describes Green Lipped Mussel from select New Zealand bays delivered to drying facilities within hours, a proprietary 30-second drying process, and direct relationships with mussel farmers (echoed in the FAQ). What is absent is any quality-system certification — there is no NASC Quality Seal or membership statement, and no cGMP, FDA-registration, HACCP, SQF, or ISO claim on any page reviewed, and the Vetnique corporate page names no facility. The score reflects one disclosed manufacturing element (Made in USA) plus sourcing detail, without facility identity or a certification body.Manufacturing is held at country level ('manufactured in the USA') with no facility name, city, or state, and no quality-system certification (NASC, cGMP, FDA-registration, HACCP, SQF, ISO) is disclosed on any reviewed page. Naming the facility and surfacing a recognized certification would lift the score toward 8-10.now manufactured in the USA using globally sourced ingredientsClaim discipline is a relative strength. The brand attaches a visible footnote to its high-confidence language: 'clinically proven to work in just 6 weeks' consistently resolves to 'Canine study conducted by the Royal Veterinary College. Excludes YuMOVE Joint Care for Young Dogs', and a dedicated Our Claims page maps marketing statements to named, dated surveys with sample sizes (CM Research n=101 for '8 out of 10 vets', Kynetec VetTrak for 'no.1 vet-recommended', YouGov and customer surveys for usage stats). Comparative claims such as '50% stronger' / '50% more power' are footnoted to 'In vitro analysis ... Data on file', and the Research page carries an explicit non-disease disclaimer, 'We do not purport to cure, mitigate, treat, or prevent any disease.' The restraint that holds the score short of 9 is that 'clinically proven' and 'scientifically proven' run pervasively above the fold while the underlying finished-formula trial is data-on-file rather than a publicly readable study, so the certainty of the wording slightly outpaces what a buyer can independently verify.High-confidence wording ('clinically proven', 'scientifically proven') is used pervasively above the fold while the finished-formula trial behind it remains 'data on file', and comparative '50% stronger' claims rest on in-vitro data on file. Anchoring these certainty claims to publicly readable studies, or qualifying them inline at the point of use, would move the score toward 9-10.Canine study conducted by the Royal Veterinary College. Excludes YuMOVE Joint Care for Young DogsOf the four evidence pillars, three are findable only with effort and one is not published at all. Science and ingredient rationale are reachable, but through a Blog / Health Guides submenu ('The Science', 'Ingredients', 'Why Green Lipped Mussels') rather than a primary 'Science' nav item, and claim substantiation sits behind a footer link, '*Additional Information / Read more about our claims', leading to the Our Claims page. There is no consolidated trust hub tying science, testing, experts, and manufacturing together. The primary 'Our Story' page resolves only to a founder narrative; the named, credentialed R&D and veterinary roster is published on The Lintbells Story page, which is not linked from primary navigation or the footer and is reachable only via on-site search or direct URL. The testing pillar has no dedicated page — probed testing/COA URLs return 404 and the crawler reports those signals false — and manufacturing is held to a single country-level line on a PDP. The Research page itself states it is 'for informational purposes only'. A buyer can locate science and claims with dedicated effort, but cannot assemble named experts, finished-product testing, and facility-level manufacturing within three clicks from a single trust anchor.The published evidence is fragmented with no single trust hub: science and ingredients sit in a Blog submenu, claims behind a footer link, and the named credentialed R&D/veterinary roster on a Lintbells Story page that primary navigation does not link to, while finished-product testing has no page at all and manufacturing is a single country-level PDP line. A consolidated 'Evidence & Trust' hub in primary navigation linking the team, science, testing, and manufacturing would move the score toward 8-10.The information provided in these studies is for informational purposes only and is not intended to be a substitute for visits to your veterinarian or as an endorsement for any product.Reviewed Jun 13, 2026Sources: 13 sources reviewed7YMYuMOVELintbells LtdYuMOVE discloses every active by dose across its joint line and footnotes its claims to named studies and surveys, including a finished-formula Royal Veterinary College trial th...Evidence Buried68.5/100Disclosure Gaps - 8RankHP
Honest Paws
Honest Paws, LLC
League City, Texas, United States68/100as of 2026-06-13Disclosure GapsHonest Paws operates one of the few buyer-usable batch-linked COA lookups in the DTC pet CBD segment, with full contaminant panels from a named ISO 17025-accredited laboratory, and publishes exact CBD doses across its hemp line. Disclosure weakens off that flagship line: non-CBD products sit outside the COA tool and several omit per-active amounts, veterinary claims are not tied to named experts, and manufacturing identity stays at country level.

The brand uses "veterinarian formulated," "expert designed," or similar language without any publicly named individual, credentials, or role.
What's in it
- Batch-linked Certificates of Analysis lookup covering 26 CBD product types and 154 batches, serving full-panel PDFs — cannabinoid potency, pesticides, mycotoxins, residual solvents, heavy metals, and microbiology — from SC Laboratories, an ISO 17025-accredited laboratory named on every report.
- CBD-line label disclosure is consistent and exact: every bite, soft chew, and tincture strength publishes hemp-oil mg with naturally occurring CBD mg per serving, plus itemized inactives and weight-banded feeding charts.
- NASC Quality Seal disclosure goes beyond the badge — a dedicated page documents biennial third-party audits, adverse event reporting, a Quality Control Manual, and GMP adherence, and PDPs identify the brand as an audited NASC Primary Supplier Member.
What's not in it
- Veterinary involvement is asserted sitewide ('Vet Recommended', 'Veterinarian-reviewed') but never connected to a named individual; the DVM bios that exist are unlinked team pages that state no formulation, review, or advisory role.
- The non-CBD line discloses materially less than the CBD line: no non-CBD product appears in the COA lookup, the Multivitamin and Omega-3 Fish Oil publish no per-active amounts, and Probiotics and Turkey Tail hold part of their panels at blend-level totals.
- Manufacturing identity is held at country level — 'USA made' with GMP and NASC language but no facility name, city, or state, and no FDA facility-registration disclosure.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsDisclosure splits cleanly along the brand's two lines. The CBD flagships publish exact per-serving numbers at every size: Calm and Mobility Bites disclose 7 mg organic full-spectrum hemp oil containing 5 mg naturally occurring CBD (2 mg/1.6 mg for Minis), and the Calm tincture publishes per-serving hemp-oil and CBD mg plus chamomile extract in mcg for each of four strengths, all with itemized inactives and weight-banded feeding charts. The non-CBD line is mixed: Green Lipped Mussel Joint Powder reaches full per-active disclosure (nine actives from Glucosamine HCl 600 mg down to Hyaluronic Acid 0.5 mg), but Pre+ Probiotics names six strains while reporting only a total-blend '5 Bill CFU (50 mg)' rather than per-strain counts, and its pumpkin flavor adds a 100 mg 'Honest Paws Proprietary Superfood Blend'. Turkey Tail powder doses each mushroom but holds an 'Honest Paws Proprietary Antioxidant Complex' at 40 mg without component amounts. The Daily Multivitamin itemizes roughly 39 actives with no amounts at all, and Omega-3 Fish Oil names salmon and pollock oil without EPA or DHA mg. Disclosure is strong on the flagship CBD line and inconsistent across the broader catalog, with multiple products using proprietary blends, grouped amounts, or no amounts.The Multivitamin and Omega-3 Fish Oil publish no per-active amounts, Probiotics reports blend-level rather than per-strain CFU, and Turkey Tail withholds amounts inside its antioxidant complex. Publishing per-active amounts on those four SKUs — at the standard the CBD line and the Green Lipped Mussel powder already meet — would lift the score toward 8-9.Active Ingredients: Turkey Tail Mushroom 500 mg, Maitake Mushroom 100 mg, Reishi Mushroom 100 mg, Shiitake Mushroom 100 mg, Nutritional Yeast 80 mg, Honest Paws Proprietary Antioxidant Complex (Vitamin C, Vitamin E, Vitamin A, Selenium) 40 mg.The brand maintains a sixteen-entry Ingredients glossary that assigns each ingredient a role, but the register is benefit-level rather than mechanism-level: 'organic barley can help your pet with digestion', L-theanine 'has been known to provide a calming effect', and chondroitin is introduced with 'Sounds very sciencey, doesn't it?'. No entry explains biological mechanism, and no entry carries a citation. PDP 'Key Ingredients' blocks follow the same pattern — inulin is 'a natural prebiotic fiber that supports healthy digestion' and Solarplast is 'a powerhouse antioxidant' — naming roles without explaining selection logic. Mechanism-adjacent content exists in the blog (probiotic articles quote immune-marker findings from named journals), but it is category-level education that is not connected back to why specific strains or doses were chosen for the formulas. There is no dedicated science or research page (/pages/science and /pages/research return 404), so a buyer cannot reconstruct ingredient-selection reasoning from the product surfaces.The glossary names roles but not mechanisms, and nothing on the product surfaces explains why specific actives, strains, or doses were selected. A mechanism-level ingredients page with citations — or formula-rationale sections on PDPs — would move this to the 6-7 band; the raw material already exists in the brand's blog citations.As an amino acid found in green tea, L-Theanine has been known to provide a calming effect in dogs and cats.Real, verifiable citation work exists but is scattered and uneven. The Mobility Bites FAQ is the strongest surface: it describes the NASC tolerability study with dose and duration (5 mg/kg daily for 90 days), links out to nasc.cc, and references a 2024 PubMed Central study — ingredient-level (CBD-level) safety research presented as safety research, which is the correct framing. The probiotics blog article names six studies with journal and year, including a 2024 randomized controlled trial, though without hyperlinks. Against that, the homepage asserts 'Formulas backed by peer-reviewed scientific studies' and a 'Clinically-Researched Ingredients' banner with no citation visible from either statement, PDPs across the line carry 'Backed by peer-reviewed scientific studies' image captions without named studies, and the probiotics PDP describes DE111 as supporting gut health without citing the strain research. The brand-overview page labels customer survey percentages 'customer efficacy studies'. No finished-formula trial is claimed, and none was found; the buyer must work out for themselves that the cited research is ingredient-level.Citation-bearing claims ('Formulas backed by peer-reviewed scientific studies', 'Clinically-Researched Ingredients', the DE111 gut-health description) do not link to the underlying studies where they appear, and the brand does not state explicitly that its evidence base is ingredient-level rather than finished-formula. Inline citations at point of claim, plus an explicit ingredient-vs-formula distinction, would lift this to 7-8.The National Animal Supplement Council (NASC) conducted a study showing that broad-spectrum cannabidiol (CBD), CBD with cannabigerol (CBG), and CBD with cannabidiolic acid (CBDA) were well-tolerated in healthy dogs when administered daily at 5 mg/kg body weight for 90 days.Veterinary involvement is asserted broadly — 'Vet Recommended Products' on the home page, 'Veterinarian-reviewed' on PDPs, a probiotics product titled 'Vet Recommended Probiotics For Dogs and Cats + Prebiotics', and an About Us mission of 'collaborating with experts to develop evidence-based products' — but none of those statements names the veterinarian behind them. Named DVMs do exist on the site: the crawl surfaced 15 bio pages under /pages/team/, including ten doctoral names, and the two reviewed in depth (Dr. Jamie Freyer, DVM, Oregon State; Dr. Ivana Crnec, DVM, Bitola) publish substantive credentials. However, neither bio states a role with Honest Paws — no formulator, advisor, or reviewer designation — and the only role stated in the directory belongs to content manager Chelsea Rivera, who 'manages written content'. The bios are unlinked orphan pages: /pages/team has no index and no team link exists in home navigation or footer. The founder surfaced by name is Erik Rivera, 'CEO & Founder' and Navy veteran, who is not presented as a clinician or formulator. Names exist somewhere on the site, but role and scope remain undisclosed.No named veterinarian is connected to formulation, product review, or the 'Vet Recommended' claims, and the existing DVM bios state no role with the brand. Publishing role and scope for the team's DVMs — and linking them from the surfaces that say 'Veterinarian-reviewed' — would move this to 8-9.We dove deep into the science and worked with veterinarians to make the best.The CBD line has genuinely strong, buyer-usable testing transparency: the Certificates of Analysis page offers product-type and batch-number dropdowns resolving to 154 batch-specific PDF reports across 26 CBD product types, and packaging carries QR codes to the same lookup. The COA inspected (Calm Bites batch 26119, issued 05/12/2026) is a five-page finished-product report naming the laboratory in full — SC Laboratories California LLC, Santa Cruz, CA, ISO/IES 17025:2017 accredited (PJLA #87168) — with quantified cannabinoid potency (Total CBD 204.450 mg/unit), pesticides, mycotoxins, residual solvents, heavy metals, microbiology by PCR and plating, foreign material, and water activity. The limits of the program are equally visible: not one non-CBD product (Probiotics, Multivitamin, Omega-3 Fish Oil, Green Lipped Mussel, Turkey Tail) appears in the lookup, even though those PDPs state 'All Honest Paws products undergo rigorous third-party testing' and reference ISO 17025 and COAs. On brand HTML pages the lab is described only as 'an ISO 17025 Accredited Lab'; its name is disclosed within the COA documents themselves.Lot-linked COA access covers the CBD line only — the non-CBD supplements assert third-party testing but publish no COAs in the lookup tool. Extending batch-level COA publication to the non-CBD line, and naming the laboratory on the testing page rather than only inside the PDFs, would lift this to 9-10.We make it easy to view any Certificate of Analysis for your product of choiceThe quality system is disclosed with above-average specificity: a dedicated NASC Quality Seal page describes a comprehensive third-party audit of manufacturing processes, GMP adherence, biennial re-audits, participation in adverse event reporting, and a Quality Control Manual with standardized operating procedures, and the Mobility PDP identifies the brand as 'an audited NASC Primary Supplier Member'. Sourcing logic is partially documented: hemp is 'USDA-certified organic' and 'Grown and raised under the open Colorado skies' from 'traceable family farms', and the Ingredients glossary states origins for eggs, peanuts, barley, and coconut oil. Facility identity, by contrast, is held at country level — 'USA made', 'state-of-the-art facilities' — with no facility name, city, or state, no FDA facility-registration statement, and no HACCP, SQF, or ISO facility certification disclosed (the ISO 17025 reference is the testing laboratory's accreditation). There is no manufacturing page; /pages/manufacturing returns 404 and quality content lives on the NASC page and PDP boilerplate.Manufacturing facility identity is not surfaced at facility/city/state level, and no FDA registration or additional facility certifications are disclosed. Naming the manufacturing partner or facility location and its certifications would lift this to 9-10; the quality-system half of the criterion is already well documented.Honest Paws undergoes regular audits every two years, maintains compliance with NASC’s stringent standards, and participates in adverse event reporting to continuously improve our products.Product pages are largely disciplined: claims stay in structure/function language ('helps maintain', 'promotes relaxation', 'supports joint health'), every PDP reviewed carries the FDA disclaimer, percentage claims are attributed to customers ('90% of customers say…', '99% of pet parents say…'), and dosing guidance repeatedly directs buyers to consult their veterinarian. Discipline is less even off the PDPs. The FAQ states the products 'do not contain THC' and that 'It is not possible for your pet to “overdose” using our CBD products', while the brand's own batch COAs quantify trace THC on the full-spectrum line (Total THC 6.450 mg/unit on Calm Bites batch 26119) — two public surfaces a buyer must reconcile. The homepage asserts 'Formulas backed by peer-reviewed scientific studies' without citation, the brand-overview page upgrades customer survey percentages to 'customer efficacy studies' without methodology, and the About mission uses 'scientifically-proven natural ingredients'. No disease-treatment claims were observed on the surfaces reviewed; the pattern is qualified product copy with looser certainty language on FAQ and brand-level pages.Claim discipline is uneven across surfaces: the FAQ's absolute THC and overdose phrasing is not reconciled with the brand's own COA data, and 'backed by peer-reviewed studies' / 'customer efficacy studies' language is not qualified at point of claim. Aligning FAQ copy with the published COAs and adding inline qualifiers or citations would lift this to 7-8.CBD is the non psychoactive party of Cannabis. These products do not contain THC- cannabis’ primary psychoactive component. Our products are 100% natural and non-toxic. It is not possible for your pet to “overdose” using our CBD products.The testing pillar is the most reachable: 'Certificates of Analysis' and 'NASC Quality Seal' are one click from the home page in the footer Learn column, and the COA lookup resolves to batch PDFs in two further selections — genuinely inspectable before purchase for the CBD line. The other pillars take progressively more effort. Manufacturing and quality-system content lives on the NASC page (footer-only) and in PDP boilerplate; there is no manufacturing page. Science content is split between an Ingredients glossary that is not linked from the home page and blog articles findable only by browsing or search. The experts pillar is effectively unreachable: the DVM bios under /pages/team/ have no index page (/pages/team returns 404), no navigation or footer link points to them, and the surfaces that say 'Veterinarian-reviewed' do not link to any named person. There is no consolidated trust hub; evidence is distributed between footer links, an unlinked glossary, orphan bio pages, and PDF documents.Two of the four pillars (science rationale, named experts) are not reachable from primary navigation at all, and testing/quality links are footer-only.

Bernie's Perfect Poop
Bernie's Best, Inc.
Austin, Texas, United States65/100as of 2026-06-13Disclosure GapsBernie's Perfect Poop discloses per-active doses across its core supplements and backs ingredients with a genuine 23-study research library and mechanism content — stronger evidence work than most Amazon-native challengers. The gaps are structural rather than in product copy: no named veterinarian, no inspectable certificate of analysis or named testing lab, and manufacturing certified (cGMP, SQF) but never named at facility level. Evidence is also split across three brand domains with no single trust hub.

The brand technically publishes meaningful science, evidence, testing, or expert disclosure, but buyers cannot reach it without dedicated effort. Evidence that exists but is hard to find counts less.
What's in it
- Per-active dose disclosure across the core supplement line — Perfect Poop lists each fiber, prebiotic and probiotic amount, and Marvelous Mobility and Healthy Hips itemize all 16 actives in mg/mcg with no proprietary blend.
- An unusually deep ingredient-research presence for the category: a 'University' library of 23 studies cited with authors, journals and links, paired with mechanism-level rationale on the Perfect Poop ingredients page.
- Disciplined claim language — PDPs avoid 'clinically proven', carry the standard non-disease disclaimer, and qualify the headline '5X DHA+EPA' claim with a stated label-comparison methodology.
What's not in it
- No veterinarian is named anywhere; the products' veterinary and formulation expertise is described as an unnamed 'Ph.D. veterinary science researchers' partnership, with only educational/R&D staff (Emily Halaszynski, Vince) surfaced by name.
- Testing is asserted as a badge ('External third-party lab testing') but is not verifiable: no laboratory is named, no certificate of analysis is published, and probed COA-lookup URLs all return 404.
- Manufacturing identity is held at country level only — cGMP and SQF certifications are named, but no facility name, city, or state and no ingredient-sourcing detail are disclosed.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsThe supplement line discloses actives at the per-ingredient level on the products a buyer would compare. Perfect Poop lists Miscanthus Grass 2,000mg, Dried Pumpkin 600mg, Flaxseed 400mg, Inulin 20mg and Xylooligosaccharides 35mg individually; Marvelous Mobility and Healthy Hips each itemize 16 actives with exact mg/mcg amounts (Turmeric Extract std. to 95% curcumin 25 mg, Boswellia 25 mg, Astaxanthin 150 mcg, Undenatured Type-II Collagen 60 mcg, Boron 750 mcg, Vitamin K2 25 mcg) and explicitly avoid a proprietary blend; OMG Omegas Chews adds a guaranteed analysis (EPA 140 mg min., DHA 125 mg min.). Dispersion holds the score below the top tier: Perfect Poop's probiotics are stated as a 1 Billion CFU total across two named Bacillus strains rather than per-strain, and its enzymes are a grouped '100 mg blend' across seven enzymes; Healthy Hips/Marvelous Mobility list 'Kelp Powder Vitamin C' without an amount; and the Charming Chompers dental chew gives a guaranteed analysis and full ingredient list but no per-active mg, consistent with treat-format labeling. The brand uses no proprietary-blend masking on the core supplements. Scored against the modal supplement SKU, the line clears an 8.A 9-10 would require complete per-active disclosure across every SKU: per-strain CFU instead of a single 1 Billion CFU total on Perfect Poop, per-enzyme amounts rather than a grouped 100 mg enzyme blend, a stated amount for 'Kelp Powder Vitamin C' on the joint products, and per-active amounts on the Charming Chompers chew. Resolving the grouped probiotic/enzyme amounts and the unquantified kelp/vitamin-C line would lift the flagship and joint products toward the top tier.Miscanthus Grass 2,000mg Dried Pumpkin 600mg Flaxseed 400mgRationale is genuinely strong on the flagship and thinner elsewhere. The Perfect Poop ingredients page explains each component in mechanism terms: Bacillus spores are 'Hardy spore-forming probiotics' that 'withstand harsh stomach acids to reach your dogs intestines', XOS 'effectively stimulate the growth of good probiotics', soluble pumpkin fiber ferments into fatty acids that fuel cells, and flaxseed contributes omega-3s and lignans. The brand-level 'University' extends this with a nutrient hierarchy and 23 research-paper summaries that describe biological roles for actives such as beta-glucans, omega-3s, boron, vitamin K2, and B. subtilis. The line-wide picture is less even: the Marvelous Mobility and Healthy Hips PDPs assert that the 16 actives are 'each backed by science' but present them as benefit bullets, with the per-ingredient mechanism content living in the separate University rather than inline on the product page. A buyer must move between the PDP and the knowledge base to connect a given active to its role, which is why the score sits at the 'inconsistent across the line' tier rather than higher.An 8-10 would require mechanism-level rationale surfaced consistently on every product page (not only the flagship), so the buyer does not have to reconstruct the logic from the University. Bringing the per-ingredient roles for the joint, omega, and dental products inline — at the depth the Perfect Poop ingredients page already achieves — would move this toward the top tier.Hardy spore-forming probiotics withstand harsh stomach acids to reach your dogs intestinesCitation behavior is unusually developed for an Amazon-native challenger and is handled with restraint. The University research library publishes 23 studies with full titles, authors, years, and links to the original sources — for example 'Evaluation of Miscanthus grass as a fiber source in pet foods' (Donadelli, 2019) links to the Kansas State full text, and the ingredients page cites PubMed/PMC, Cambridge, and PLOS ONE entries for the actives. Crucially, this is ingredient-level research presented in an ingredient-research context, and the brand does not dress it up as finished-formula proof: no PDP uses 'clinically proven' or 'clinically tested', and the OMG Omegas '5X' headline is qualified by an explicit label-comparison methodology rather than a borrowed trial. What holds the score below the top tier is that the brand does not explicitly state the ingredient-versus-finished-formula distinction or disclose that no finished-product clinical trial exists; the research-paper pages note no specific Bernie's product is linked, leaving the buyer to infer which study supports which claim.A 9-10 would require the brand to state plainly that its cited studies are ingredient-level rather than finished-formula evidence, to disclose whether any Perfect Poop or other finished-product trial exists, and to map specific studies to the product claims they support. Adding that explicit framing — and connecting library entries to the products that rely on them — would close the remaining distance.Evaluation of Miscanthus grass as a fiber source in pet foodsNo veterinarian is named anywhere on the brand's surfaces. The home page states the brand bases its product formulas on 'the latest veterinary research and innovative ingredients', and the Our Story page says the founders 'partnered with Ph.D. veterinary science researchers, formulation experts, and ingredient specialists' — but none of those researchers or formulators is identified. The named individuals the brand does surface are its educational/R&D staff: Emily Halaszynski (B.S. Animal Sciences, Auburn) and Vince (B.S. analytical chemistry, University of Illinois; 27+ years R&D; 40+ patents), both presented as the leads of the University knowledge base. Vince is described as the 'R&D expert who ensures science guides every formula', which is the closest the site comes to a named formulator, yet he is a chemist identified by first name only and his per-product role is not itemized. Because the actual veterinary and formulation expertise behind the products is asserted but unnamed, a buyer cannot verify it from the named-people signals that do exist, which places the criterion at the mid tier.Moving up requires naming the veterinarian(s) or formulator(s) behind the products with their credentials, role, and scope of involvement — and surfacing them from primary navigation rather than only describing an unnamed 'Ph.D. veterinary science researchers' partnership. Even one fully credentialed, named veterinary formulator-of-record tied to the line would lift this several tiers.partnered with Ph.D. veterinary science researchers, formulation experts, and ingredient specialistsTesting is asserted consistently but is not verifiable by a buyer. Every product page and the brand home carry badge-level language — 'External third-party lab testing' on the PDPs and 'Independent Lab Quality Testing' on the home page — yet no testing laboratory is named anywhere on the brand's surfaces. No certificate of analysis is published on any PDP, and there is no COA lookup tool: seven common COA/testing URL patterns were probed and all returned 404, with no COA link present in store or brand-site navigation or footer. There is no lot-level traceability, and the contaminant, microbial, and potency panel scopes are not disclosed; the only processing-level detail is the OMG Omegas note 'Molecularly Distilled Fish Oil', which is a processing claim rather than a test report. The brand therefore asserts third-party testing without naming a lab, surfacing a COA, or connecting testing to specific batches, which matches the tier-4 anchor.Reaching tiers 7-10 requires naming the third-party laboratory, publishing certificates of analysis, and ideally a lot-linked COA lookup with disclosed contaminant, microbial, and potency panels across the line. Even a single named lab plus a downloadable batch COA on the flagship would move the score off the floor.External third-party lab testingThe brand discloses a named quality system but not facility identity. The home trust strip and product pages consistently state 'GMP Compliant Facility', 'SQF Certified Facility', and 'Made in USA', and the Perfect Poop PDP reads 'Made in the USA in GMP- and SQF-certified facilities' — so both cGMP and the stronger, named SQF scheme are surfaced across multiple SKUs. What holds the score at the tier where the quality system is disclosed but facility identity is held at country level is that no facility is named: there is no manufacturer name, city, or state anywhere on the brand's surfaces. No NASC seal or membership statement appears, no FDA-registration claim is made, and no HACCP or ISO certification is cited. Sourcing logic is generic — the Our Story page references unnamed 'accredited suppliers' without ingredient origins or traceability detail. This is a clean match to the 'quality system disclosed, facility identity at country level' tier.A 9-10 requires naming the contract manufacturer at facility, city, and state level, pairing it with the already-disclosed cGMP/SQF certifications, and documenting sourcing logic and traceability from primary navigation. Surfacing the facility identity is the single largest lever, since the quality-system disclosure is already in place.Made in the USA in GMP- and SQF-certified facilitiesMarketing language is generally disciplined with isolated overreach. The product pages avoid 'clinically proven', 'cures', and 'guaranteed results'; benefit language stays measured ('Helps maintain a normal inflammatory response', 'Supports heart, brain, and joint health'); and the philosophy page carries the regulatory disclaimer that products are 'not intended to diagnose, treat, cure, or prevent any disease.' The headline comparative claim on OMG Omegas, 'Up to 5X more DHA+EPA omega-3s per chew', is qualified above the fold by a stated methodology defining the comparison and date, which is good practice. The one instance that overshoots the visible evidence base is the Healthy Hips PDP statement that competitor ingredients 'have been proven less effective', a comparative efficacy claim presented without an inline citation. Because the pattern is otherwise restrained and the most aggressive numeric claim is explicitly qualified, the score sits at the 'generally disciplined, isolated overshoot' tier rather than lower.A 9-10 would require every comparative or efficacy-tier claim to carry an inline source — in particular the Healthy Hips 'proven less effective' comparison would need a visible citation — and consistently qualified language across all pages. Citing the evidence behind that single comparative claim would remove the lone overshoot.Others use glucosamine, chondroitin, and MSM because they sell well (even though they’ve been proven less effective). Not us…Of the four evidence pillars, only the science pillar is genuinely easy to reach. The University knowledge base and the Perfect Poop ingredients page are reachable from the main 'Learn' navigation, and the knowledge base is presented as 'free of sales-driven language.' Manufacturing certifications (GMP, SQF, Made in USA) are visible as home-page badges. The other two pillars are not buyer-inspectable: there is no COA or testing-report page (probed patterns return 404 and no lab is named), and the named experts surface only deep inside the University rather than from primary navigation. The evidence is also split across three brand domains — the flagship marketing site (berniesperfectpoop.com) funnels to Amazon with almost no evidence, the store carries the panels, and the University carries the science — with no single consolidated trust hub. A buyer cannot reach all four pillars within a few clicks from one home page, which places the criterion at the mid tier.An 8-10 would require all four pillars — science, testing, named experts, and manufacturing — reachable within three clicks, ideally from a single consolidated 'Evidence & Trust' hub rather than scattered across three domains. Adding an inspectable testing/COA page and surfacing the experts from primary navigation are the two changes that would most improve discoverability.free of sales-driven languageReviewed Jun 13, 2026Sources: 15 sources reviewed9BPPBernie's Perfect PoopBernie's Best, Inc.Bernie's Perfect Poop discloses per-active doses across its core supplements and backs ingredients with a genuine 23-study research library and mechanism content — stronger evid...Evidence Buried65/100Disclosure Gaps - 10RankNL

The brand technically publishes meaningful science, evidence, testing, or expert disclosure, but buyers cannot reach it without dedicated effort. Evidence that exists but is hard to find counts less.
What's in it
- Per-active dose disclosure is complete on the flagship joint and liver lines, down to branded-ingredient identity (FCHG49 glucosamine, TRH122 chondroitin) and delivered silybin (24 mg Silybin A+B), with strain-level NCIMB identifiers on the probiotic.
- Vertically integrated manufacturing is disclosed past the category norm: Nutramax-owned facilities in Lancaster, South Carolina, with a published eight-step quality process, in-house Chemistry and Microbiology labs, and a label-claim guarantee.
- Claim qualification is unusually consistent — every '#1 Veterinarian Recommended' superlative across all reviewed domains carries a survey-source footnote, and product copy stays inside structure/function language.
What's not in it
- No public COA, lot lookup, or named third-party laboratory exists anywhere on the surface — the detailed testing program is entirely self-attested and in-house, with contaminant panels never itemized.
- Clinical-style claims outrun their public citations: Proviable's '6 published studies in dogs and cats' and 'Clinically Researched' badge carry no reference list, and Dasuquin's comparative research claim discloses its cell-culture basis only in fine print.
- No formulating veterinarian, scientist, or advisory board is named at product level; the only named DVM is the President & CEO, visible solely in media-center press releases, while the research library is login-gated to professionals.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsThe three largest lines publish complete per-active panels on their PDPs. Cosequin Chewable Tablets with MSM discloses Glucosamine HCl (FCHG49) 600 mg, Sodium Chondroitin Sulfate (TRH122) 300 mg, MSM 250 mg, and Manganese 3 mg per tablet; Dasuquin With MSM Soft Chews publishes both strengths active-by-active (600/400/250/60/50/45/20/16 mg small-dog; 900/800/350/90/75/90/40/32 mg large-dog) plus a full inactive list; Denamarin discloses SAMe 225 mg and Silybin-phosphatidylcholine complex 82 mg 'providing 24 mg of Silybin A+B' per tablet. There are no proprietary blends anywhere in the reviewed line — the branded actives (FCHG49, TRH122, NMX1000 ASU) are identified with specific amounts. Dispersion appears at the secondary-amount level: Proviable-DC names all seven strains with NCIMB culture-collection identifiers but guarantees only the 5 billion total CFU, not per-strain counts, and Welactin's Guaranteed Analysis groups EPA+DHA at 1330 mg within 1610 mg total omega-3s without an individual EPA/DHA split or named fish species. Panels live on PDPs only; brand homepages and category pages do not surface them.Per-strain CFU amounts on the Proviable probiotic line and an individual EPA/DHA breakout (plus fish-species identity) on Welactin are the two disclosures holding the line below near-complete. Publishing those secondary amounts at the tier the joint and liver lines already achieve would support a 9.S-Adenosylmethionine 225 mg and Silybin-phosphatidylcholine complex (SPC) 82 mg, providing 24 mg of Silybin A+BRationale is present in places but inconsistent across the line. Denamarin's About page is the strongest surface: SAMe is explained as shown to 'markedly increase liver levels of glutathione' and 'help protect liver cells from cell death,' silybin as supporting 'a healthy oxidative balance,' with six references beneath. The Dasuquin PDP fine print explains the formula's logic in mechanism language — 'cell culture research has shown that Dasuquin's specific glucosamine and low molecular weight chondroitin sulfate synergistically stimulate cartilage matrix production' — and the About Dasuquin page assigns roles ingredient-by-ingredient (Boswellia 'to help inhibit various inflammatory mediators'; green tea 'to help provide antioxidant benefits and help protect cartilage'). Proviable publishes a genuine why-multi-strain rationale, including probiotic/prebiotic/synbiotic education and a strain-detection comparison. Cosequin and Welactin, by contrast, rely on benefit assertions ('helps support your dog's cartilage'; supports 'skin and coat health, plus overall wellness') without mechanism content, and no ingredient-level encyclopedia exists at brand level.Mechanism content is product-siloed: Denamarin and Dasuquin explain ingredient logic while Cosequin and Welactin describe benefits only. A brand-level ingredient rationale hub — or extending the Denamarin-tier explanation to the flagship Cosequin line — would lift this toward 8-9.Dasuquin is a multi-synergistic formula: cell culture research has shown that Dasuquin’s specific glucosamine and low molecular weight chondroitin sulfate synergistically stimulate cartilage matrix production, while ASU also acts synergistically with glucosamine and with chondroitin sulfate.Citation discipline varies sharply by product domain. Denamarin's About page publishes a numbered six-reference block with authors and journals ('Center SA, Warner KL, McCabe J, et al. Am J Vet Res 2005;66:330-341'), all veterinary-species work, with most references hyperlinked to PubMed or NIH (PMC) records — the real citation standard the rest of the line does not meet. Proviable leads with 'clinically researched' and '6 published studies in dogs and cats,' and its PDP bullets 'Clinically Researched - Backed by multiple published studies,' yet no citation, author, or journal appears anywhere on the domain, including the FAQ; the homepage describes a specific result (seven-strain detection in '91% of dogs') without identifying the study. The About Dasuquin page states the 'combination of Glucosamine, Chondroitin Sulfate, and ASU works better than Glucosamine and Chondroitin Sulfate alone' without a reference, while the soft-chew PDP discloses the basis only as in-vitro fine print ('cell culture research has shown'). The media center announces studies (a December 2022 Cobalequin clinical study in dogs; a 2015 glucosamine/chondroitin trial) without linked citations, and the centralized research library sits behind the login-gated Vet & Medical Portal, out of buyer reach.The brand demonstrably runs and publishes research but does not surface citations where the claims are made: Proviable's six claimed studies and Dasuquin's comparative research claim carry no public reference list, and no page distinguishes finished-formula trials from ingredient or in-vitro work. Replicating the Denamarin reference block across the line, with finished-product labeling, would support an 8.Proviable is a clinically researched multi-strain probiotic supplement for dogs and cats containing billions of CFUs of beneficial bacteria that help support a healthy intestinal balance.The company's identity is veterinary — the legal entity is Nutramax Laboratories Veterinary Sciences, Inc. and the product domains carry survey-qualified '#1 Veterinarian Recommended' superlatives (category-specific: '#1 Veterinarian Recommended Retail Joint Health Supplement Brand' on Cosequin, '#1 Veterinarian Recommended Omega-3 Supplement Brand' on Welactin, '#1 Veterinarian Recommended Supplement Company' on Proviable) — but expert disclosure at product level is anonymous. The public surface names exactly two credentialed-adjacent individuals, both in executive context: 'Todd Henderson, DVM, President and CEO of Nutramax Laboratories' (media-center press release; also named on the Our Passion brand page as 'Our CEO, Dr. Todd Henderson') and founder 'Dr. Robert "Dr. Bob" Henderson' (February 2026 award release, credentials not stated on brand pages). No formulator, staff veterinarian, nutritionist, or scientific advisor is named anywhere a buyer would look: probes of /team, /leadership, /experts, and /advisory-board redirect to the site's error template, the crawler's named-expert detection found zero candidates, and PDPs attribute work to unnamed teams ('our quality control team,' 'our chemists'). A buyer can verify that a DVM leads the company but cannot connect any named person to the formulation or scientific oversight of the products.No named individual is publicly connected to product formulation, research leadership, or scientific review — the named DVM's disclosed role is executive, surfaced in press releases and a philanthropy page rather than a product or R&D context. A team or R&D page naming the veterinarians and scientists behind the Translational Research Laboratory, with roles and credentials, would move this to 7-8.Todd Henderson, DVM, President and CEO of Nutramax Laboratories, has been named a recipient of the Christian Employers Alliance (CEA) 2025 Kingdom Impact Award.Nutramax publishes an unusually detailed in-house testing narrative: 'Every Nutramax supplement is tested for contaminants, backed by more than 80 quality checks, and guaranteed to meet label claims,' supported by an eight-step Our Quality walkthrough covering raw-material analytical chemistry ('identity, purity, and other specifications') and microbiology testing, an internal raw-material Certificate of Analysis gating production, in-process checks every thirty minutes, finished-product testing in 'our own Chemistry and Microbiology labs,' and stability testing. What the narrative does not include is any externally verifiable artifact: no third-party laboratory is named anywhere on the surface (testing is explicitly in-house), no COA is published or retrievable (probes of /coa, /certificate-of-analysis, /lab-results, and /quality-results all return the error template), no lot-lookup exists, and the contaminant panel is never itemized — a buyer cannot see which contaminants, what limits, or any batch result. The label-claim guarantee functions as a potency commitment, but it is self-attested rather than documented.The program description is line-wide and specific, but nothing is independently inspectable: no named third-party lab, no published COA or lot lookup, no itemized contaminant panel. Naming an external laboratory or publishing batch COAs for even the flagship lines would lift this to 6-8.Every Nutramax supplement is tested for contaminants, backed by more than 80 quality checks, and guaranteed to meet label claims, so you can purchase with confidence.Nutramax is vertically integrated and says so: products are made in 'our own world-class manufacturing facilities in the U.S.A.,' and facility identity is disclosed well past country level — Our Story states 'Located in Lancaster, South Carolina, Nutramax researches, develops, and manufactures high quality products,' every footer carries the 946 Quality Drive, Lancaster, SC 29720 campus address, and the media center documents a '200,000 square foot expansion' as 'Lancaster County's Largest Manufacturing Employer.' The quality system is disclosed as cGMP ('current Good Manufacturing Practices') with SOPs and an eight-step process including supplier qualification ('well-vetted and approved suppliers'), incoming-material inspection, and stability chambers. The certification scope stops there: no NASC Quality Seal or membership statement appears on any reviewed page, and no FDA facility registration, ISO, SQF, or HACCP disclosure exists. Sourcing is held at the 'globally sourced ingredients' level on PDPs without ingredient origins.Facility identity is disclosed (own campus, city, state, street address) but the quality system rests on self-attested cGMP with no certification body, audit program, NASC membership, or FDA registration statement named, and sourcing logic stays at 'globally sourced.' Naming the certifying or auditing bodies and publishing ingredient-origin detail would support a 9.Located in Lancaster, South Carolina, Nutramax researches, develops, and manufactures high quality products to support human health and animal health.Qualification discipline on the brand's signature superlative is conspicuously consistent: every '#1 Veterinarian Recommended' instance across cosequin.com, denamarin.com, welactin.com, and proviable.com carries a survey-source footnote, with Cosequin adding the precise scope qualifier 'Among retail brands. Survey conducted among small animal veterinarians who recommended oral joint health supplements' — and the Cosequin hero version is footnoted above the fold ('Source: Survey conducted among veterinarians who recommend animal supplements'). Product copy stays inside structure/function lanes ('helps support joint comfort,' 'help support a healthy intestinal balance'), and the Proviable FAQ even volunteers cautionary guidance about which pets probiotics are not recommended for. The overshoots are research-certainty phrasings without a reference at the claim site: the About Dasuquin page states the 'combination of Glucosamine, Chondroitin Sulfate, and ASU works better than Glucosamine and Chondroitin Sulfate alone' while the soft-chew PDP discloses the cell-culture basis only in fine print, and Proviable's 'Clinically Researched' badge surfaces no citation. No disease-treatment, cure, or lifespan claims were observed anywhere in the reviewed line.Comparative and clinical-style phrasings on Dasuquin and Proviable run ahead of what is cited where the claim appears — the in-vitro basis for 'works better than' sits in fine print, and 'Clinically Researched' links to nothing. Inline citations or explicit study-type qualifiers at the claim site would support a 9.Among retail brands. Survey conducted among small animal veterinarians who recommended oral joint health supplements.Two of the four evidence pillars are one click from the corporate home page: Our Quality (the full eight-step testing and manufacturing narrative) and Our Story (facility location) sit in primary navigation. The rest of the evidence is fragmented across a multi-domain architecture spanning the corporate site and five flagship product domains — supplement-facts panels live on the per-product domains (cosequin.com, dasuquin.com, denamarin.com, proviable.com, welactin.com) that a buyer must first discover from the corporate product directory, and the only public study citations sit on one product's About page (denamarin.com), where they are at least hyperlinked to PubMed. Named credentialed individuals are findable only by reading media-center press releases or a philanthropy page, and the consolidated research library is behind the login-gated Vet & Medical Portal ('Exclusive Content' in product-domain footers). There is no trust hub, no COA surface, and the corporate site's probed evidence-page patterns (/research, /coa, /team) all redirect to the error template.Quality narrative is highly navigable but the science, citation, and expert pillars require dedicated effort across multiple domains or are gated to professionals.

Leap Years
Animal Biosciences, Inc.
United States64.5/100as of 2026-05-23Disclosure GapsStrong on clinical evidence and named veterinary involvement, weak on label disclosure and testing. The brand publishes one of the most credible pieces of evidence in the pet-supplement category — a peer-reviewed finished-formula RCT at NC State CVM — and surfaces a real veterinary team. But buyers cannot identify the specific NAD precursor or senolytic compound in the product, cannot retrieve a lot-specific COA, and cannot find the manufacturing facility by name, city, and state. The result is an unusually clinical-evidence-forward brand sitting on top of a conventional pet-supplement label / testing / facility disclosure layer.
Public Evidence System Named Vet ReviewerIngredient RationaleDisease-Claim-FreeNASC Member Finished-Formula Trial Named Mfg FacilityWorth NotingActive Identity Withheld
The brand uses proprietary blends, grouped amounts, or other label conventions that prevent a buyer from reading the per-active dose on at least one product in the line. Distinct from Line Inconsistency — captures the case where actives are hidden, not where products differ.
What's in it
- Published finished-formula RCT of the Leap Years product itself — double-blind, placebo-controlled, conducted at North Carolina State University College of Veterinary Medicine, peer-reviewed in Scientific Reports (Nature Portfolio, May 2024) with Dr. Natasha Olby (DACVIM Neurology) as principal investigator.
- Multiple DVMs publicly named with full credentials and state of practice, including internal scientific leadership (Dr. Ginny Rentko, VMD, DACVIM, Chief Veterinary Medical Officer) and the trial PI (Dr. Olby) plus seven independent practitioner commentators — well above the pet-supplement floor of 'our veterinary team.'
- Disease-treatment claims are avoided; clinical-style language ('Clinically tested,' 'Studied in Dogs') is anchored to a real trial that buyers can read at nature.com, not to a phantom study.
What's not in it
- Active ingredients are not named at the chemical level — the brand discloses 'NAD Booster' (200mg / 600mg) and 'senolytic' as functional categories, confirms the product does not contain NMN, but never tells the buyer which precursor (NR, NAR, NA) or which senolytic compound (fisetin, quercetin, etc.) is in the formula.
- Testing disclosure is generic: no named third-party laboratory, no public COA lookup, no per-lot traceability, no itemized contaminant / microbial / pesticide / potency panel.
- Manufacturing facility is not named at the facility-name / city / state level; sourcing is described as 'globally sourced ingredients' with no named suppliers or countries of origin.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsLeap Years is a single-SKU product (one product, sized by dog weight). The brand discloses chew-level functional totals — 'LY-D2 (brown) is 200mg of an NAD Booster. LY-D6 (golden) is 600 mg of a combination of NAD Booster and senolytic' — and confirms the product 'does not contain NMN.' But it does not name the specific NAD precursor by chemical identity (NR, NAR, NA), does not name the specific senolytic compound (fisetin, quercetin, etc.), does not split the 600mg LY-D6 into NAD-portion vs senolytic-portion mg, and shows no Supplement Facts panel on the PDP. The mg disclosure that exists lives on the FAQ page, not on the PDP — buyer must hunt for it. Active-by-active disclosure is absent. The 600mg combination chew is effectively a functional proprietary blend at the actives level. The score sits in the 'some dose-related signals exist on the public surface, but the buyer cannot verify enough to distinguish substantive disclosure from marketing language' tier — chew totals are real, but the actives behind them are not.Buyer cannot identify which NAD precursor or which senolytic compound is in the product, and cannot determine the active-by-active mg split inside the 600mg combination chew. No Supplement Facts panel surfaced on PDP.LY-D2 (brown) is 200mg of an NAD Booster. LY-D6 (golden) is 600 mg of a combination of NAD Booster and senolytic.Brand publishes a meaningful, accessible explanation of WHY NAD+ boosting plus senolytic clearance is a defensible pairing for aging dogs — 'Senescent cells consume increased amounts of NAD+, depleting cellular reserves' is a real mechanism argument, not pure benefit assertion. The rationale is structured around the hallmarks-of-aging framework and explicitly cites the Sinclair lab as scientific lineage. Aging Research / Scientific Literature page cites six external research items with DOI links including Lopez-Otin 'Hallmarks of Aging' (Cell 2023), Rajman/Sinclair NAD+ Boosting (Cell Metabolism 2018), Wiley & Campisi Metabolic Roots of Senescence (Nature Metabolism 2021), and Urfer/Kaeberlein companion-dog lifespan (Canine Medicine and Genetics 2020) — these connect mechanism claims to real published science. Two structural caps hold the score below 8: (a) the rationale stops at the category level (NAD booster, senolytic) and never connects to specific actives — buyer cannot read 'this product uses NR at X mg because NR is the most-validated precursor in dogs'; (b) the science pages do not visibly grade ingredient-level evidence vs finished-formula evidence inside an evidence taxonomy. Ingredient-selection logic is opaque because the ingredients themselves are not named at the chemical level.Mechanism explained at category level (NAD+ pathway, senescence), not at chemical-active level. No ingredient-selection rationale tied to specific compounds because specific compounds are not named.Senescent cells consume increased amounts of NAD+, depleting cellular reserves.Leap Years is one of very few pet supplement brands surveyed that publishes a real, peer-reviewed, finished-formula clinical trial of its own product. The trial is double-blind, placebo-controlled, conducted at North Carolina State University College of Veterinary Medicine, led by Dr. Natasha Olby (DACVIM Neurology) and colleagues, and published in Scientific Reports (Nature Portfolio, open-access, peer-reviewed) in May 2024 — DOI 10.1038/s41598-024-63031-w. Brand pages link out directly to the publication so buyers can read the underlying paper. Primary endpoints (cognition, frailty, activity, owner-assessed quality of life) are reported with at least one explicit statistical claim ('statistically significant difference compared with placebo'). The trial is NOT borrowed ingredient research; it tests the finished LY-D6 + LY-D2 chew system in aged dogs. Two structural shortfalls hold the score below 10: (1) brand pages occasionally refer to the journal as 'Nature' rather than as Scientific Reports — buyers may infer a higher-tier journal than the one that actually published the trial; (2) the brand's broader Aging Research / Scientific Literature page does not visibly distinguish ingredient-level / mechanism-level research (Lopez-Otin, Rajman, Wiley & Campisi) from the finished-formula trial — they are presented under the same 'Scientific Literature' heading with no evidence grade applied.Journal attribution is sometimes loose ('Nature' vs Scientific Reports). Aging Research page does not separate ingredient-level / mechanism research from finished-formula evidence with an explicit grading system.A double blind, placebo controlled clinical trial with Leap Years was conducted at North Carolina State University College of Veterinary Medicine.Multiple DVMs are publicly named: Dr. Ginny Rentko (VMD, DACVIM, Chief Veterinary Medical Officer — internal scientific leadership), Dr. Natasha Olby (Vet MB, PhD, DACVIM Neurology, NC State CVM — external trial PI), and at least seven independent practicing DVMs quoted by full name, credentials, and state on the 'Why Veterinarians Are Excited' editorial. This is materially stronger than the typical pet-supplement 'our veterinary team' anonymous framing. The 7 (rather than 8 or 9) reflects three real structural gaps: (a) Dr. Ginny Rentko does NOT have a consolidated bio page on Leap Years' own site — her formal title and CEO role are surfaced primarily through the 'As Seen In' Dogster article rather than through a dedicated team / leadership page; (b) the Our Story page surfaces no named individuals at all and signs off as 'The Leap Years Team'; (c) the seven quoted DVMs are commentators / partners, not formal scientific advisors, and their scope of involvement (formulation, review, advisory) is not disclosed.Brand's internal scientific leadership (Rentko) lacks a consolidated bio page on the brand's own site. Quoted DVMs are testimonial commentators, not formal advisory board members with disclosed scope.Dr. Natasha Olby, Vet MB, PhD, DACVIM (Neuro)Brand asserts third-party testing ('The soft chews are tested in a registered laboratory') but does not name the laboratory (no Eurofins, NSF, ConsumerLab, or equivalent third-party identity). No specific contaminant, microbial, pesticide, identity, or potency panel is itemized. No public COA lookup is available — buyers cannot retrieve a lot-specific Certificate of Analysis for the bottle they are about to buy. No per-lot traceability surface. This is generic testing language without verifiable substance, despite the brand's otherwise strong evidence profile on the clinical-trial axis. The mismatch between the trial-grade discipline and the testing-disclosure discipline is one of the brand's largest substance-vs-facade gaps.No named third-party laboratory, no per-lot COA lookup, no itemized contaminant / microbial / pesticide / potency panel. Buyer cannot independently verify the testing program at the bottle level.The soft chews are tested in a registered laboratory with methods to ensure that Leap Years meets our label claims, and the product is free of any impurities.Quality system disclosure is moderate: cGMP claimed, NASC registered, FDA-registered facilities asserted. These are real, named certification bodies (cGMP + NASC + FDA registration) and place the brand above the floor of 'Made in USA, that's it.' However, the facility itself is not named at the facility-name / city / state level. Sourcing is described as 'globally sourced ingredients' without named suppliers or countries of origin per ingredient. No HACCP, SQF, or ISO certifications surfaced. Quality system disclosed; facility identity not surfaced.Facility not named at facility-name / city / state level. Sourcing disclosure is generic ('globally sourced') with no named ingredient suppliers or countries of origin.manufactured, packaged, and tested in FDA registered facilities under strict quality policiesOn the substantive axis the brand earns real credit: it avoids explicit disease-treatment claims ('treats arthritis,' 'cures dementia'), uses 'supports' / 'addresses' / 'limits' qualifier verbs rather than 'cures' / 'guarantees,' and the 'Clinically tested' badge is anchored to an actually-published trial rather than to a phantom study. However, several discipline gaps hold the score below 8/10: (a) the 'Clinically tested' / 'Studied in Dogs' badges on the home page hero do not carry inline effect-size or n qualifiers above the fold — the buyer must click into the trial results page to discover the n, duration, and effect sizes; (b) the PDP hero uses 'Addresses the root causes of aging at the cellular level' — a phrasing the cognition / frailty / activity / happiness endpoints of the trial cannot directly substantiate, because those endpoints measure outward behavior rather than cellular biomarkers; (c) Aging Expectations carries 'Limits cognitive decline,' 'enhance movement and restore vigor,' and 'Improves overall healthspan' with no qualifier that not all dogs respond equally or that results vary; (d) marketing materials refer to the trial's journal as 'Nature' rather than the more accurate Scientific Reports, which is a minor but real journal-tier optical inflation; (e) the comparative claim 'Up to 3X NAD+ boosting power compared to other brands' is not substantiated with named competitors or measured methodology. Net: the brand is disciplined on the LARGE claim axis (noAbove-the-fold clinical badges lack inline qualifiers (n, duration, effect size). 'Cellular-level' framing on PDP overshoots the behavioral endpoints of the actual trial. Some pages refer to the journal as 'Nature' rather than Scientific Reports.Addresses the root causes of aging at the cellular levelHeader navigation surfaces 'THE SCIENCE' (dropdown to Aging Science, Aging Research, Our Quality, Clinical Trial Results), 'FOR VETS' (Veterinarian Partners, Case Reports), 'REVIEWS,' 'MEDIA,' and 'FAQs.' Most evidence pillars are reachable within two clicks. The clinical trial (the brand's strongest evidence) is reachable from the home page in one or two clicks and links out to nature.com. Buyer Access is held below 8 by three structural factors: (a) there is no single consolidated 'Evidence' or 'Trust Center' hub — evidence is distributed across THE SCIENCE, FOR VETS, MEDIA, and individual blog posts; (b) testing / COA evidence is on a separate page (Our Quality) that does not link to either a COA lookup or named lab disclosure; (c) the brand's leadership / scientific team is not surfaced on a single team page — Dr. Ginny Rentko's role is reconstructed across multiple surfaces (Aging Science page + Dogster byline + 'Why Vets Are Excited' references).

Finn Wellness, LLC
New York, NY64/100as of 2026-06-13Disclosure GapsFinn presents above the DTC median on label transparency: all six core soft-chew supplements publish per-active doses with no proprietary blends beyond grouped probiotic CFU totals. Manufacturing is disclosed at quality-system level (cGMP, SQF, NASC) and batch microbial testing is described organism-by-organism. The gaps cluster on verifiability — no named laboratory, no public COA, no cited studies behind 'clinically proven' language, and no named formulator — with most quality content held in the brand's help center rather than primary navigation.
Public Evidence System Named Vet ReviewerIngredient RationaleDisease-Claim-FreePublic COA LookupPer-Lot TraceabilityNASC Member Finished-Formula Trial Named Mfg FacilityWorth NotingBorrowed Evidence
The brand uses "clinically tested," "clinically proven," "study-backed," or trial-adjacent language without surfacing finished-formula or properly qualified ingredient-level evidence.
What's in it
- Complete per-active dose disclosure across all six core soft-chew supplements — from Organic Passion Flower 125 mg on Calming Aid to Glucosamine HCL 500 mg on Hip & Joint — with defined per-chew serving sizes, weight-based dosing charts, and on-page inactive ingredient lists.
- Quality-system disclosure names three frameworks (cGMP compliance, SQF certification, NASC Quality Seal via third-party audit) and the batch testing description names its microbial panel organism-by-organism (Salmonella, Listeria, Enterobacteriaceae) with lot-code traceability.
- Three veterinarians are named with credentials directly on the home page (Dr. Laura Robinson, DVM; Dr. Kerri Nelson, DVM, PGRS-C; Dr. Farren Billand, DVM), and core PDP claim language stays consistently qualified ('helps occasional stiffness,' 'supports calm').
What's not in it
- No third-party laboratory is named and no COA or lot-lookup is published — every-batch testing and traceability codes are described in help-center text, but no testing document is buyer-accessible.
- 'Clinically proven' and 'selected based on clinical research' statements carry no citation anywhere on the reviewed surface — no study, author, or journal is identified, and no science or research page exists on the site.
- Manufacturing, testing, and sourcing detail lives only in the footer-linked Gorgias help center rather than the primary site; the facility is identified at country level only, and the named DVMs' published role is limited to endorsement quotes with no disclosed formulator.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsAll six core soft-chew supplements publish complete per-active panels with serving sizes defined per chew and weight-based dosing charts. Calming Aid discloses all seven actives in mg per 2.5 g chew (Organic Passion Flower 125 mg down to Melatonin 1 mg); Hip & Joint discloses nine actives per 3.5 g chew (Glucosamine HCL 500 mg, MSM 200 mg, Organic Turmeric 150 mg, Chondroitin Sulfate 100 mg, Green Lipped Mussel 75 mg, plus vitamins, Yucca, and BioPerine 5 mg); Allergy & Itch discloses Colostrum 150 mg through Bromelain 10 GDU; Skin & Coat discloses EPA 95 mg and DHA 68 mg; Multivitamin's guaranteed analysis runs from Glucosamine 250 mg to Riboflavin 1.25 mg. Two qualifications hold the line below near-complete. First, probiotic actives are grouped: Digestive Probiotics discloses 'Total Microorganism 3 Billion CFU' across six named species and the Multivitamin label reads 'Probiotic Blend 500M CFU' — species are named but per-strain CFU and strain identifiers are not. Second, the topper line steps down a tier: the Pumpkin Plus PDP publishes proximates only (Crude Fiber 18%, Moisture 9%), with per-active answers such as beta-carotene per tablespoon held in help-center articles. Panels also render as label images and screenshots rather than HTML text, so the disclosure is visible but not text-searchable.Per-strain CFU and strain identifiers on the two probiotic-bearing SKUs, and per-active amounts on topper PDPs rather than in help-center answers, are what separate the line from the 9-10 tier. Publishing the panels as machine-readable text in addition to label images would remove the remaining verification friction.Table showing active ingredients per 3.5g soft chew supplement, listing 8 ingredients with dosages from 5mg to 500mgIngredient-role content exists for most of the line, but it is distributed across PDP infographics and the external help center rather than a consolidated science surface, and it stays at benefit-role depth. Each supplement PDP carries a 'What's Inside' infographic with one-line callouts (turmeric, glucosamine, mussel on Hip & Joint; bee propolis, quercetin, salmon oil, colostrum, probiotics on Allergy & Itch). The Calming Aid product FAQ assigns roles to three of seven actives ('Organic Ginger Root for digestion, Organic Passion Flower for discomfort, Organic Chamomile for a healthy inflammatory response'). Help-center explainers carry the deepest mechanism content — the EPA/DHA article notes dogs cannot synthesize these fatty acids, and the Pumpkin Plus 'What's inside' article explains fiber and pectin roles for all five ingredients — while the selection-process article asserts formulation 'based on clinical research' from 'primary university research to published clinical trials.' No ingredient encyclopedia exists, no citation accompanies any mechanism statement, and some surface copy is benefit framing rather than biology (the Calming Aid PDP leads with 'Supports Calm & Relaxation' and 'Helps Reduce Stress' rather than explaining how its actives work).A consolidated, citation-bearing ingredient page on the primary domain — explaining each active's biological role at the depth the EPA/DHA article already achieves — would lift this to the 7-8 tier. What holds it at 6 is that the buyer must assemble rationale from PDP image callouts and scattered help-center articles, and meaningful actives (melatonin, L-tryptophan, quercetin, CoQ10) carry no published role explanation at all.The active ingredients in our supplements have been selected based on clinical research. We refer to a wide range of studies in formulation, from primary university research to published clinical trials from industry and academic sources, to identify natural ingredients with proven efficacy in dogs.No study citation of any kind is published on the reviewed surface — no author, journal, title, or link — and the sitemap walk plus URL probes confirm there is no science, research, or studies page to hold one. Clinical-style language nonetheless appears at the brand level: the help center states Finn formulates 'with only the best ingredients that are clinically proven to support your dog's health and overall well-being' and describes drawing on 'published clinical trials from industry and academic sources' with 'proven efficacy in dogs'; the home page promises 'rock-solid science' and 'premium, proven ingredients'; the Plaque Patrol FAQ calls the chews 'the ultimate science-backed defense.' To the brand's credit, the claims are consistently ingredient-level — no finished-formula trial is asserted, so no unrelated research is presented in finished-product framing — and the six supplement PDPs themselves avoid 'clinically proven' wording. But a buyer who wants to read the research behind any of these statements has no path to it from any page reviewed.Publishing the actual studies behind the 'selected based on clinical research' and 'clinically proven' statements — even a simple reference list per product — is the single change that would move this score toward the 6 tier. Holding the score at 4 is the complete absence of any readable citation paired with recurring clinical-certainty phrasing.That’s why we formulated our supplements with only the best ingredients that are clinically proven to support your dog’s health and overall well-being.Three veterinarians are named with credential letters and quotes directly on the home page, About page, and PDPs: Dr. Laura Robinson, DVM; Dr. Kerri Nelson, DVM, PGRS-C; and Dr. Farren Billand, DVM — Dr. Nelson with a photograph beside her PDP quote. Visibility is therefore strong: a buyer meets named DVMs without any navigation effort. What remains undisclosed is role and scope. All three appear under 'Loved by Pets, Endorsed by Vets' as endorsement-quote providers, with no biographies, institutions, or descriptions of involvement in formulation or review. Meanwhile the brand separately uses formulation-credit language that is attributed to no one: a 'Vet Formulated' badge appears in an Allergy & Itch gallery image, the wellness blog hero markets 'Vet-Formulated Dental Chews,' and the help center says Finn 'consult[s] with scientists, veterinarians, and industry experts' and describes 'a small team of dogs, dog lovers, vets, and animal nutritionists' — none of them named. The buyer can verify that named vets endorse the products but cannot verify who formulated them.Disclosing the actual formulator or scientific advisors by name — with credentials, role, and scope, and connecting the 'Vet Formulated' badge to a person — would lift this to 8-9. The score sits at 7 because the named DVMs' published role is limited to endorsement quotes, leaving credentials thin and formulation involvement unverifiable.Getting dogs to take pills can be difficult. We love Finn soft chews because they are easy to administer and expertly formulated. Dogs think they're delicious.Finn's testing disclosure is unusually specific in its description and entirely undocumented in its evidence. The food-safety help article states 'Every batch of our soft chews is lab-tested for Salmonella, Listeria, and Enterobacteriaceae before leaving the facility, and has a unique code that tracks ingredient supplier, manufacturing shift, testing, and processing' — naming a three-organism microbial panel, asserting every-batch cadence, and describing lot-code traceability across supplier, shift, testing, and processing. The 'How is Finn different?' article repeats the every-batch claim under 'Tested & Approved.' However, no laboratory is named anywhere on the reviewed surface, no COA is published, and no lot-lookup exists: probes of /pages/lab-results, /pages/coa, /pages/certificate-of-analysis, and /pages/batch-testing all return 404, storefront search for 'COA' returns 0 results, and the help center's 209-article sitemap contains no lab-report article. Contaminant (heavy-metal) and potency testing are not mentioned at all, so the published scope is microbial-only and the testing claims, while concrete, cannot be verified against any document by a buyer.Naming the testing laboratory and publishing even sample COAs would lift this to the 7-8 tier; a lot-linked lookup tied to the batch codes the brand already describes would reach higher. The score holds at 5 because the described program — every-batch microbial testing with traceability codes — produces no buyer-accessible artifact, and contaminant and potency panels are undisclosed.Every batch of our soft chews is lab-tested for Salmonella, Listeria, and Enterobacteriaceae before leaving the facility, and has a unique code that tracks ingredient supplier, manufacturing shift, testing, and processing.The quality system is disclosed with three named frameworks: manufacturing occurs 'in a US-based, current Good Manufacturing Practice (cGMP) compliant facility that is Safe Quality Foods (SQF) certified and certified by the National Animal Supplements Council (NASC).' The NASC credential is substantiated as 'earned … through a comprehensive 3rd party audit and ongoing compliance,' and the seal appears on supplement PDP galleries. Process detail goes further than most DTC peers: cold-press extrusion is described ('using very low temperatures to preserve maximum nutrient potency'), and batch codes tracking 'ingredient supplier, manufacturing shift, testing, and processing' are disclosed. Facility identity, however, is held at country level — no facility name, city, or state — and sourcing logic is generic: 'made in the USA from globally sourced ingredients. The source of the ingredients varies between products,' with only ad hoc exceptions (Wild-Caught Alaskan Salmon oil as the EPA/DHA source). All of this lives in the footer-linked help center rather than on a manufacturing page on the primary domain.Naming the manufacturing facility at city-and-state level and publishing ingredient-level sourcing logic are what separate this from the 9-10 tier. Surfacing the existing cGMP/SQF/NASC disclosure on a primary-domain manufacturing page rather than help-center articles would also strengthen buyer reachability.We manufacture our soft chews in a US-based, current Good Manufacturing Practice (cGMP) compliant facility that is Safe Quality Foods (SQF) certified and certified by the National Animal Supplements Council (NASC).Core PDP claim hygiene is genuinely disciplined: supplement headlines use qualified structure-function language — 'Help ease occasional joint stiffness caused by daily exercise,' 'Helps Occasional Stiffness & Soreness,' 'Supports Calm & Relaxation,' 'Helps Reduce Stress' — and label images disclose cautions including interaction warnings on Calming Aid. No lifespan or longevity claims appear, and the hero above the fold ('Hi! We love your dog.') carries no claim at all. The overshoots form a recurring pattern of science-confidence phrasing that the published evidence base (zero citations) cannot support: 'clinically proven' ingredients in the help center, 'rock-solid science' and 'proven ingredients' on the home page, 'scientifically-balanced formula' in the Multivitamin benefits article, and 'the ultimate science-backed defense' plus 'Targets Plaque & Gingivitis' and 'Kills Odor-Causing Bacteria' on the Plaque Patrol page. PDP 'What To Expect' timelines also assert week-by-week outcomes ('Week 2 … More spring in your dog's step,' 'Month 3 … Healthier hip, joint, and connective tissues'), and curated testimonials carry condition narratives the brand could not claim directly.Citing or qualifying the 'clinically proven' and 'science-backed' phrases, and softening outcome-certain 'What To Expect' timelines, would lift this to 8. The score holds at 7 because the unsupported science-confidence language recurs across the help center, home page, and dental line rather than appearing in one isolated campaign.Help ease occasional joint stiffness caused by daily exercise, promote cartilage development, and enhance joint mobility with Glucosamine, Chondroitin, and Turmeric.Reachability splits cleanly by pillar. Label evidence is excellent: actives are named in product blurbs on the home page itself ('The ultimate trio for joint support and tissue repair — Glucosamine, Chondroitin & MSM') and full dose panels sit one click away on every supplement PDP. Named-vet visibility is immediate — three DVMs with quotes appear on the home page without any clicks. Manufacturing, testing, and ingredient-selection evidence, by contrast, is reachable only through the footer 'FAQs' / 'Help Center' links, which leave the primary domain for the Gorgias-hosted help center (finn-support.gorgias.help) where the relevant articles sit under an 'About Finn' category — about three clicks, but on a support subdomain a buyer would not naturally browse for evidence. There is no trust hub, and primary navigation is commerce-only with no science, testing, or quality entry. Two frictions compound this: dose panels render as images whose alt text only summarizes the table, and the wellness blog is empty, so no editorial surface backfills the missing science pillar.A consolidated quality-and-science page on petfinn.com — surfacing the cGMP/SQF/NASC disclosure, batch-testing description, and ingredient rationale that already exist in the help center — would lift this to 8-9. The score holds at 7 because two of the four evidence pillars are footer-only and off-domain, and one (citable science) has no destination at all.The ultimate trio for joint support and tissue repair — Glucosamine, Chondroitin & MSM.Reviewed Jun 13, 2026Sources: 19 sources reviewed12FFinnFinn Wellness, LLCFinn presents above the DTC median on label transparency: all six core soft-chew supplements publish per-active doses with no proprietary blends beyond grouped probiotic CFU tot...Borrowed Evidence64/100Disclosure Gaps - 13RankNV

Garmon Corp. (operating as NaturVet); subsidiary of Swedencare AB
Temecula, California56.5/100as of 2026-05-23Disclosure GapsNaturVet is a 30+ year mass-market brand whose substance evidence is unusually disciplined at the label panel (per-active mg disclosure across the line is real) and at the manufacturing identity layer (Temecula, CA facility, FDA / UL / NASC stack). The brand falls into 'Disclosure Gaps' band because it offers no named veterinary expert, no science / mechanism content, and no per-lot COA lookup despite extensive 'veterinarian formulated' marketing. The 70-dog joint-care trial citation is a substantive bright spot but is isolated from any broader citation discipline.
Public Evidence System Named Vet ReviewerIngredient RationaleDisease-Claim-FreeNASC Member Finished-Formula Trial Named Mfg FacilityWorth NotingUnnamed Experts
The brand uses "veterinarian formulated," "expert designed," or similar language without any publicly named individual, credentials, or role.
What's in it
- Per-active dose disclosure (mg / IU / mcg / CFU) is consistent across nine sampled PDPs spanning All-In-One, Senior, Calming, Urinary, Hip/Joint, Allergy, Digestion, and Breed-Specific categories — only one proprietary-blend instance found (ArthriSoothe-GOLD's 130 mg enzyme blend with named components).
- Manufacturing identity disclosed at city / state level (Temecula, California, in-house facility) with FDA registration, UL third-party facility audit, NASC founding-preferred-supplier seal verified on the NASC registry, and cGMP compliance — facility-level transparency above mass-market median.
- Advanced Joint Care PDP cites a real finished-formula 70-dog placebo-controlled trial with a quantified effect size (2.6 greater odds of activity increase at 25 days vs. placebo) and a 'Results may vary' qualifier — substantive citation discipline rare among mass-market competitors, though no publication link is provided.
What's not in it
- Zero named veterinarians, formulators, or scientific advisors on the brand surface. The 'veterinarian formulated' framing appears on every PDP, the home page strip, and the A Step Ahead landing page without a single verifiable named individual; on-site search for 'Nardi' (the advisor identified in NaturVet's May 2026 press release) returns no results, and no team / experts / advisory-board page exists.
- No Science, Research, Studies, or How-It-Works page exists (probed URLs return 404 or 403). PDP-level ingredient rationale is single-sentence role assertion ('Milk Thistle to help maintain liver health') without mechanism explanation, dose-response discussion, or per-ingredient citation. No PubMed links anywhere in the blog or PDP surfaces.
- No public per-lot COA lookup. UL audits the facility but the lab performing per-batch contaminant / microbial / potency assays is not named, and contaminant analytes are not enumerated. NASC's required random product testing is described in plain English but results are not surfaced.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsAcross nine sampled PDPs spanning All-In-One, Senior, Calming, Urinary, Hip/Joint, Allergy, Digestion, and Breed-Specific categories, NaturVet publishes per-active mg / IU / mcg / CFU disclosure on every product reviewed. Multi-ingredient formulas (Senior 5-in-1, Aller-911, Cranberry Relief, Incontinence) all disclose component amounts down to single-digit milligrams. Probiotic and enzyme SKUs include activity-unit definitions (SKBU, LU, CMCU, PU) — substantive transparency that lets buyers cross-compare assays. Drug-interaction warnings are disclosed where relevant (MAO inhibitors for Quiet Moments, blood thinners for Senior 5-in-1, CYP enzyme interactions for Cranberry Relief). The single proprietary-blend instance is the 130 mg 'Proprietary Enzyme Blend' on ArthriSoothe-GOLD (Advanced Joint Care) — components are named (alpha-Amylase, Lipase, Cellulase, Protease, Bacillus coagulans, Fructooligosaccharides) but per-component amounts are obscured at a total weight. This is unusually disciplined disclosure for a brand of NaturVet's product-line breadth and mass-market positioning. Score holds below 9 because of the one proprietary-blend instance on a premium SKU; the modal product disclosure is closer to 9.ArthriSoothe-GOLD uses a 130 mg total 'Proprietary Enzyme Blend' rather than per-component amounts (components are named). Without this single instance the brand would clear 9.Proprietary Enzyme Blend (alpha-Amylase, Lipase, Cellulase, Protease, Bacillus coagulans, Fructooligosaccharides) 130 mgNaturVet does not publish a Science, Research, or How-It-Works page anywhere on the brand site (probed URLs /pages/science-library, /pages/research-library, /pages/how-it-works, /pages/mechanism-of-action all return 404 or 403). The brand has no ingredient encyclopedia, no per-active mechanism content, and no editorial framework explaining why specific actives were selected. PDP-level rationale exists in single-sentence form — for example, Senior 5-in-1 says 'Turkey Tail Mushroom to support immunity, Ginkgo biloba to promote cognitive function, Milk Thistle to help maintain liver health, Coenzyme Q10 to help support heart health and Lutein to help maintain eye health.' These are role assertions, not mechanism explanations. Aller-911 says 'Essential Fatty Acids... to help maintain proper skin moisture, respiratory health, and normal histamine levels' — again role-level, not mechanism-level. No explanation of WHY these ingredients act, no discussion of dose-response, no comparison to dietary baseline. The blog (/blogs/tips-and-tricks/) is consumer-facing wellness content (heat stroke, dental care, vitamins overview) rather than ingredient-specific mechanism documentation. The brand earns credit for naming ingredient roles consistently across the line, but the disclosure tier is benefit/role assertion rather than mechanism reasoning.No Science / Research / How-It-Works page. No per-ingredient mechanism content. No ingredient encyclopedia. PDP rationale is single-sentence role assertion, not biological mechanism.Contains Turkey Tail Mushroom to support immunity, Ginkgo biloba to promote cognitive function, Milk Thistle to help maintain liver health, Coenzyme Q10 to help support heart health and Lutein to help maintain eye health.NaturVet's Advanced Joint Care (formerly ArthriSoothe-GOLD) PDP cites a real finished-formula clinical study: 'In a 70 dog study, dogs on Advanced Joint Care had 2.6 greater odds of showing an increase in activity after 25 days (relative to baseline activity), compared to dogs on a placebo. Results may vary.' The trial description is properly asterisked, qualified with 'Results may vary,' and explicitly placebo-controlled — this is a substantive disclosure that distinguishes NaturVet from brands that cite only ingredient-level research. However, no journal, author, publication date, sample-size detail beyond n=70, peer-review status, or DOI link is surfaced. Buyers cannot read the underlying study. The ArthriSoothe-GOLD SEO meta description and JSON-LD use 'clinically tested and designed to promote healthy pet joints' language; body content is more qualified than the meta copy. Across the rest of the line, NO PDP cites any other clinical or ingredient-level study. The blog content does not link PubMed citations. Cranberry Relief's PDP claims urinary support without citing the well-established cranberry / urinary literature. Senior 5-in-1 names ingredients with established mechanisms (Milk Thistle for liver, CoQ10 for heart) without citing any of the available research. Result: one finished-formula trial referenced (substance), but no citation discipline as a brand-wide pattern.Finished-formula trial cited on a single product without publication / journal / author / link. No ingredient-level study citations elsewhere on the line. SEO meta description uses 'clinically tested' more broadly than the body content supports.*In a 70 dog study, dogs on Advanced Joint Care had 2.6 greater odds of showing an increase in activity after 25 days (relative to baseline activity), compared to dogs on a placebo. Results may vary.Substance-vs-facade fails decisively on this criterion. NaturVet uses 'Veterinarian formulated' framing on every PDP, the home page strip ('Formulated by vets, adored by pets!'), and the A Step Ahead campaign landing page. The Our Story page invokes a 'holistic vet' in the founding anecdote ('with help from their holistic vet') without naming that person. No team page, no experts page, no advisory-board page exists in primary navigation or footer. The on-site search for 'Nardi' (the veterinary advisor identified externally in a May 2026 PR Newswire announcement) returns zero results. The Our Story page does not name the founders (Scott Garmon historically; Geoff Granger current CEO per press release), the original formulator, or any current veterinarian. The 'holistic vet' from the founding story is uncredentialed and unnamed. The celebrity endorsement (Mario & Courtney Lopez) is framed as 'wellness ambassadors' — they are explicitly not veterinarians or experts. Per rubric principle that only buyer-verifiable evidence counts, expert claims that require browsing PR Newswire to discover named individuals fail. The brand is a textbook 'Unnamed Experts' watchout: extensive 'veterinarian formulated' framing without a single named veterinarian visible on the brand surface.Zero named veterinarians, formulators, nutritionists, or scientific advisors on the brand surface. Dr. Nina Nardi DVM exists per external press release but is not surfaced anywhere on naturvet.com. No team / experts / advisory-board page exists. 'Veterinarian formulated' is asserted across the line without any verifiable named individual.We care so much, we make it ourselves. Formulated by vets, adored by pets!The Quality page describes a substantive testing program in plain English: ingredient quarantine and identity testing, three independent-laboratory verifications for new ingredients, annual re-checks, microbial testing for Salmonella and E. coli, finished-product safety testing, and batch tracking. The brand asserts in-house traceability ('Each batch is tracked and recorded, so we can trace every product from start to finish'). NASC Quality Seal membership is verified externally on the NASC primary-supplier registry. UL is named as the facility auditor on multiple surfaces. However, several substance gaps prevent a higher score: (1) NO public per-lot COA lookup tool exists — buyers cannot search a bottle's LOT number; (2) the lab performing the actual contaminant / microbial / potency assays is not named (UL audits the FACILITY, not the per-batch testing); (3) the contaminant panel is not analyte-specific (no heavy metals, pesticides, or solvent analytes disclosed); (4) NASC's required random product testing is not surfaced with results; (5) the home page mentions Infrared Spectroscopy for identity confirmation, which is a real method, but no buyer-facing report exists. The testing program described is more substantive than mass-market median, yet falls short of mid-tier DTC brands operating a real lot-linked COA portal.No public per-lot COA lookup. Lab performing per-batch testing not named (UL audits the facility, not individual batches). Contaminant panel not analyte-specific. NASC random-product-testing results not published.All new ingredients are tested three times by an independent laboratory. Annual re-checks make sure ingredient quality stays consistent. Microbial testing checks for harmful bacteria like Salmonella, E. coli and other microbes.Manufacturing disclosure is one of NaturVet's strongest pillars. The Our Story page identifies the facility location at city / state level: 'All of our supplements are meticulously studied, formulated and crafted with care in Temecula, California.' Quality system disclosure stacks four certifications: FDA-registered and inspected, third-party audited by UL (Underwriters Laboratories), founding preferred supplier of NASC with Quality Seal, and cGMP-compliant. NASC membership is independently verifiable on the NASC primary-supplier registry. NaturVet manufactures its own products in-house at the Temecula facility — buyers are not navigating contract-manufacturer layers. Sourcing logic is partially disclosed at the country level ('trusted partners in places like Norway, Iceland, Germany, and Canada') without naming specific ingredient suppliers. Parent ownership is disclosed (Swedencare AB subsidiary on NASDAQ First North, Stockholm) — a Swedish public-market parent provides a structural accountability anchor most DTC competitors lack. Score holds below 9 because: facility identity is given at city/state level but the specific facility name and street address are not published; supplier identities are held at country level only; NASC audit date and findings are not surfaced.Facility name and street address not published (city / state level only). Supplier identities held at country level. NASC audit date and findings not disclosed.

With solutions for hips, joints, coats, calming and beyond, we embrace every pet, dogs and cats alike and every opportunity to make a pawsitive impact on our pets' lives.Claim language is generally restrained at the body-content level. PDPs consistently use 'helps,' 'supports,' 'helps maintain' framing rather than 'cures,' 'guaranteed,' or disease-treatment language. Cautions are disclosed inline on PDPs (drug interactions for blood thinners, MAO inhibitors, CYP enzymes; hypoglycemic effects; GI irritant warnings). The 70-dog Advanced Joint Care study is properly qualified with 'Results may vary' and asterisked. NASC Quality Seal compliance enforces FDA-recommended caution statements which appear on PDPs. The home page does not assert 'clinically proven,' 'cures,' or absolute outcomes; promotional copy focuses on the 'A Step Ahead' proactive-wellness positioning. Two friction points hold the score below 9: (1) the ArthriSoothe-GOLD SEO meta description and JSON-LD use 'clinically tested and designed to promote healthy pet joints' — broader than the body content's qualified single-study disclosure, and surfaced in Google SERP results where buyers first encounter the brand; (2) 'Veterinarian formulated' is broader than the disclosed scope, since no veterinarian is named on the brand surface — buyers reading 'Veterinarian formulated for use in dogs and cats over the age of 12 weeks' on every PDP cannot identify the formulating veterinarian. No above-the-fold home-page qualifier ('not a substitute for veterinary care') visible to a casual buyer.ArthriSoothe SEO meta uses 'clinically tested' broader than body-content qualification supports.

PDPs are reachable by category from the mega-menu.

Dover, Delaware (registered address; manufacturing facility not disclosed)55/100as of 2026-05-23Disclosure GapsVitaDog has a real editorial-policy spine, a substantive peer-reviewed sources page, and named third-party testing — but the hero trust stack (Vet Reviewed, Clinically Dosed, Public Eurofins COAs) overpromises against the underlying surface. The testing panel is microbiology-only on one SKU, the 'vet-led advisory board' has no named members, no finished-formula trial exists, and no manufacturing facility is disclosed. Stronger than the median DTC peer on editorial-policy scaffolding; weaker than the marketing implies on substance.

Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsVitaDog publishes mg-level disclosures for roughly 22 of the 40+ actives — across the single-ingredient explainer pages and within the powder formulation: glucosamine HCl 600mg (grouped with MSM), inulin 100mg, pumpkin 100mg, sodium hexametaphosphate 75mg, astragalus 50mg, quercetin 50mg, liquorice 50mg, rosemary 30mg, turmeric 25mg, vitamin C 25mg, plus per-mg disclosure on most vitamins and minerals. However, four meaningful sub-blends remain grouped rather than per-component: Joint Blend (600mg combining glucosamine HCl + MSM), Oil Blend (459.54mg combining fish oil + flaxseed + evening primrose + MCT, with no EPA/DHA/ALA/GLA breakdown), B Vitamin Blend (2.34mg combining six B vitamins), and the eight-strain Probiotic Blend (1 billion CFU total, no per-strain CFU). Inactive ingredients are named but not quantified. The flagship PDP does not display a standardized Supplement Facts panel on the main product page; full per-active disclosures must be reconstructed across the 25 single-ingredient sub-pages.Four grouped sub-blends remain non-per-component (joint, oil, B vitamins, probiotic CFU); inactive ingredients are not quantified; the flagship PDP does not surface a consolidated Supplement Facts panel — buyer must hunt across single-ingredient pages.Glucosamine HCl plus MSM (600 mg combined per scoop)VitaDog publishes a substantial ingredient-rationale surface: roughly 25 single-ingredient explainer pages (turmeric, glucosamine, MSM, quercetin, inulin, pumpkin, astragalus, liquorice, rosemary, vitamin C/A/D3/E, calcium, niacinamide, magnesium, piperine, B-complex, manganese, zinc, copper, biotin, probiotics, oil blend, sodium hexametaphosphate), plus a Science Hub with longer-form deep dives that include mechanism-level content (e.g., glucosamine as GAG precursor and MMP inhibitor; curcumin acting on NF-kB and COX-2; EPA modulating prostaglandins and leukotrienes). The vet-science hub claims '15 health systems' coverage but does not provide a system-by-system ingredient-to-mechanism map. Coverage is uneven: the turmeric and fish-oil pages cite real peer-reviewed studies; the quercetin science blog post contains zero citations and rests on benefit language.Mechanism coverage is uneven across the line — some single-ingredient pages cite peer-reviewed studies, others rely on benefit language with no citations. No consolidated system-by-system rationale map ties the '15 health systems' claim to specific ingredient roles.Curcumin inhibits several inflammatory pathways simultaneously, which is rare for a natural ingredient.VitaDog publishes a 41-entry Sources page with PubMed IDs, DOIs, authors, journals, and volume/issue information — a substantive ingredient-level evidence library. The editorial policy formalizes a three-tier evidence grading (S/A peer-reviewed; B AKC/manufacturer/COA; C reputable blogs) and commits to FTC-compliant structure-or-function language. However, the brand's home hero, vet-science page, vet-portal, and roughly two dozen other pages all carry the framing 'the veterinary research backed all in one supplement that promotes all aspects of your dogs health with 40+ active ingredients,' plus an above-the-fold 'Clinically Dosed' badge. There is no finished-formula RCT on VitaDog itself; the only RCT cited adjacent to formula claims (McCarthy 2007 glucosamine-chondroitin) is an ingredient-level study on glucosamine and chondroitin alone, not the VitaDog formulation. The brand does not explicitly tag any cited study as ingredient-level versus finished-formula on its evidence surface.Brand-level 'clinically dosed' and 'veterinary research backed' framing borrows ingredient-level evidence to support finished-formula buyer expectations. No finished-formula RCT exists, and the Sources library is not segregated into ingredient-level vs finished-formula evidence tiers.VitaDog Nutrition is the veterinary research backed all in one supplement that promotes all aspects of your dogs health with 40+ active ingredients.Two named individuals are publicly disclosed at full bio depth: Cameron Main (co-founder, editorial reviewer) and Chris Noble (co-founder). Neither holds DVM, VMD, RVT, MS Nutrition, RD, or board certification — the editorial policy explicitly states 'We are dog parents and product builders, not licensed veterinarians' and commits to adding a DVM editorial advisor by Q3 2026. Despite this honest internal disclosure, the brand simultaneously markets the formula as 'Vet Reviewed' (home hero badge), 'veterinary research backed' (sitewide), and 'guided by a vet-led advisory board of nutritionists, veterinary surgeons, and food scientists' (vet-science page) — without naming a single advisor, veterinarian, or nutritionist. The vet-portal page is a lead-capture form with no named veterinary contact. Site search for 'DVM' returns only the editorial policy page; site search for 'Katie Marrie' (a name surfaced by the brand-crawl heuristic) returns zero results.Zero named DVM, veterinary nutritionist, or scientific advisor is publicly disclosed.

The page claims every production lot is tested by Eurofins. However, the published testing panel is microbiology-only: E. coli (AOAC 991.14), Salmonella spp. (AOAC-RI 121501), Yeast (FDA BAM Ch. 18), Mold (FDA BAM Ch. 18). No heavy metals testing is disclosed. No pesticide residue testing is disclosed. No potency verification on actives is disclosed. No ingredient identity testing in COAs is disclosed. The brand itself acknowledges 'Independent third-party microbiological testing is the bare minimum for any product going into a dog's daily diet.' Only one SKU (Daily All-In-One Powder) is publicly tested; Custom Blend Oil COAs are 'available on request.'

No FDA facility registration number, no HACCP, no SQF, no ISO 9001/22000 facility certification is disclosed. The Delaware business address listed on the contact page (8 The Green, Suite B, Dover, DE) is a corporate registered-agent address commonly used by Shopify DTC brands, not a manufacturing facility. No contract-manufacturer partner is named. No sourcing-logic disclosure (ingredient suppliers, raw-material standards) is on the public surface.Facility identity, location, certification body, FDA registration, and sourcing logic are all absent from the public surface. The disclosure is at the country-and-claim level only, well below the facility-named threshold.Made in the USAThe editorial policy is genuinely disciplined for blog content — explicit FTC-compliant structure-or-function commitment, three-tier evidence framework, and an honest internal disclosure that the founder-reviewers are not DVMs. Disease-treatment claims are avoided ('not veterinary advice' disclaimers appear in blog footers). However, the brand's commercial surface contains four hero badges — 'Vet Reviewed', 'Clinically Dosed', 'Science-Backed Formula', 'Public Eurofins COAs' — each of which sets a buyer expectation that the underlying surface only partially supports (no named DVM, no finished-formula RCT, no full contaminant panel). Hero copy 'Give your dog the years they deserve' frames longevity outcomes without inline qualification. The vet-science page asserts 'Every ingredient is there because the science demands it' — a strong evidence claim coupled with no finished-formula trial.

- Manufacturing and quality-system disclosure is concrete for the mass-market tier: Vermont manufacture, SQF-certified facilities, cGMP adherence, and NASC founding-member status (via parent FoodScience, LLC) with the seal program's five quality-control requirements enumerated on a dedicated page.
- Claim register is consistently restrained — support/help language with 'occasional' qualifiers, zero 'clinically proven' or disease-treatment language found, and a published review-moderation policy removing reviews that imply disease claims.
What's not in it
- No named veterinarian, nutritionist, or formulator appears anywhere on the brand surface — About Us names no people, the blog is house-bylined, and no team or experts page exists.
- Testing is asserted (third-party ingredient testing, NASC random independent-lab testing) but no laboratory is named, no COA is viewable or requestable on-site, and nothing connects testing to specific lots or enumerates panel analytes.
- The flagship calming active is a 5 mg proprietary 'Colostrum Calming Complex® Biopeptide Blend' described only as 'bioactive proteins,' probiotic SKUs stop at genus/species without strain designations, and manufacturing identity is held at state level rather than facility, city, and state.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsPer-active dose disclosure is the brand's strongest pillar and holds across all twelve PDPs reviewed, from flagships to the lowest-priced problem solvers. Calming discloses Thiamine 35 mg, Colostrum Calming Complex® Biopeptide Blend 5 mg, and L-Theanine 5 mg per 1.5 g chew; BusyButter discloses four actives per 16 g tablespoon over a two-item ingredient list; Hip + Joint and Hip + Joint Pro disclose six actives each with source species named (Glucosamine HCl from shrimp and crab, Chondroitin Sulfate porcine); Daily Multi publishes a 22-nutrient Guaranteed Analysis with an AAFCO footnote. The standard extends to secondary SKUs: Lawn Aid (Brewers Yeast 300 mg, Methionine 150 mg), UT Support (N-Acetyl Glucosamine 100 mg, D-Mannose 50 mg), and the $10.50 Breath Bites, which includes a yield spec ('Spirulina 100 mg yielding Chlorophyll 2 mg'). Inactive-ingredient lists and per-weight dosing directions are complete on every page reviewed. Two ambiguities hold the line below near-complete: the flagship Calming line's marquee active is a proprietary 5 mg 'Colostrum Calming Complex® Biopeptide Blend' whose composition is described only as 'bioactive proteins,' and Daily Probiotic identifies its organism at genus/species level (Bacillus coagulans, 120 million CFU) without a strain designation.The Colostrum Calming Complex® Biopeptide Blend on the flagship Calming line discloses a total amount (5 mg) but not its component bioactive proteins, and probiotic SKUs stop at genus/species without strain designations. Publishing the blend's composition and strain-level identifiers would lift the line toward near-complete disclosure.Active Ingredients Per 1 Chew (1.5g): Thiamine (Vitamin B1) 35 mg Colostrum Calming Complex® Biopeptide Blend 5 mg L-Theanine 5 mgPet Naturals maintains a brand-wide ingredient glossary ('What's Inside') in its primary navigation, with one-line role descriptors for every ingredient across seven categories — a structural surface many mass-market peers lack. Some entries reach mechanism level: L-Theanine is a 'Calming amino acid that stimulates production of dopamine and serotonin to support relaxation,' and PDP prose occasionally explains biology, as on Skin + Coat (Vitamin E 'protects the omega fatty acids so they can do their job supporting skin and coat') and Lawn Aid (methionine and yucca 'help reduce ammonia and nitrogen levels in urine that cause lawn burn'). The depth, however, is uniformly one sentence: no entry carries a citation, a dose rationale, or an explanation of why an ingredient was selected over alternatives. The PDP 'Healthful Ingredients' tiles reuse the generic glossary lines rather than product-specific rationale — UT Support displays the Glucosamine HCl joint-role descriptor on a urinary-tract product whose panel active is N-Acetyl Glucosamine, leaving the buyer to reconcile the mismatch. The content connects ingredients to roles across the whole line, but distinguishing the ingredient logic from marketing language requires interpretation the brand does not supply.Glossary and PDP rationale stops at one-line role descriptors with no research citations, no dose logic, and no product-specific selection reasoning; generic tiles are reused out of product context. Per-ingredient mechanism pages with cited research would move this toward consistent product-level rationale.Calming amino acid that stimulates production of dopamine and serotonin to support relaxation.No study citation of any kind appears on the reviewed brand surface — no PubMed link, no journal reference, no author name, on any of twelve PDPs, the ingredient glossary, the FAQ, or the blog. The brand also does not use 'clinically tested' or 'clinically proven' language anywhere reviewed; the crawler's claim sweep across the site returned zero clinical-claim hits. The study-flavored language that does exist is uncited: the FAQ's batch-variation answer asserts 'Stability studies show that any changes to products during shipping are minimal' with no report or citation, and the same page states that all ingredients 'undergo third-party testing to ensure their safety, purity and efficacy' — an efficacy-verification assertion with no supporting documentation a buyer can read. The brand neither claims finished-formula trials exist nor discloses that they do not, so a buyer comparing Calming or BusyButter against clinically-positioned competitors has no evidence statement to weigh in either direction.Zero citations exist anywhere on the surface, and the FAQ's stability-study and efficacy-testing assertions surface no underlying documents. Publishing ingredient-level citations in the What's Inside glossary, or an explicit statement distinguishing ingredient research from finished-formula evidence, would move this score materially.Stability studies show that any changes to products during shipping are minimal.No named veterinarian, nutritionist, formulator, or scientific advisor appears anywhere on the reviewed brand surface. The About Us page — the closest surface to a team page — names no people at all, in any role. The blog is bylined 'Pet Naturals' on every visible post. Probes for /our-team and /veterinarians return 404, the 54-URL crawl inventory contains no team or experts page, and on-site searches for 'DVM,' 'veterinarian,' and 'doctor' return no results. Notably, the brand also does not use 'veterinarian formulated' or 'developed with experts' framing: the only veterinarian references on the surface are consult-your-own-vet advisories in the FAQ ('we recommend consulting with your veterinarian'). The NASC Quality page references the NASC Scientific Advisory Committee, but that is the council's body, not brand personnel. The result is a brand surface with no disclosed expert involvement of any kind — no claim made, and no person to verify.No expert involvement is disclosed at any tier — no name, no credential, no anonymous formulation claim. Surfacing even one named formulator or veterinary reviewer with credentials and role on the About Us page would move this score several tiers; parent company FoodScience's formulation staff are not referenced on the Pet Naturals surface.However, we recommend consulting with your veterinarian to determine if a specific combination is suitable for your cat or dog.Testing is asserted at two levels but documented at none. The FAQ states that all ingredients, regardless of origin, 'undergo third-party testing to ensure their safety, purity and efficacy,' and separately that the brand conducts 'extensive third-party testing to ensure the safety, quality and efficacy of all of our products.' The NASC Quality page adds the program-level requirement to 'Submit to random product testing by an independent lab to ensure ingredients meet label claim' — a potency-verification disclosure inherited from NASC membership. Beyond these assertions, nothing is buyer-verifiable: no laboratory is named anywhere on the surface, no COA is posted or requestable on-site, no lot or batch lookup exists (/coa and /lab-results return 404), and no contaminant or microbial analytes are enumerated. The testing claims cover the whole line in scope but produce no artifact a buyer can inspect for any single product, so the disclosure stops at the boundary between a described program and a verifiable one.No named laboratory, no COA access, no lot-level linkage, and no analyte-level panel scope are published — testing exists on the surface only as assertion. Naming the independent lab and posting even representative COAs would move this score to the named-lab tier; a lot-linked lookup would move it further.Regardless of their origin, all of our ingredients undergo third-party testing to ensure their safety, purity and efficacy.The quality system is disclosed concretely: the FAQ states products 'are manufactured in Vermont, USA' in facilities that are 'SQF-certified and strictly adhere to NASC guidelines and Current Good Manufacturing Practices (cGMP) as defined by the Food and Drug Administration.' The NASC Quality page discloses that parent FoodScience®, LLC is a founding member of NASC and enumerates five program requirements, including written SOPs, a real-time adverse-event reporting system, labeling compliance, FDA-CVM-recommended label warnings, and random independent-lab product testing. Corporate identity is anchored on-site: FoodScience®, LLC is named as parent, with the 929 Harvest Lane, Williston, Vermont address published in the footer. Facility identity, however, is held at state level — the brand says 'Vermont, USA' without naming the plant or stating that the Williston address is the manufacturing site — and no certificate, audit date, or certifying body for the SQF claim is published. Sourcing is disclosed in one-line form only ('high-quality ingredients sourced in the U.S. and throughout the world,' plus a fair-trade organic palm note on BusyButter) rather than as a sourcing policy.Facility identity is disclosed at state level rather than facility, city, and state, and the SQF claim carries no certificate, certifying body, or audit date. Naming the manufacturing facility and publishing certification documentation would move this to the strong-disclosure tier.Pet Naturals® supplements & treats are manufactured in Vermont, USA. Our manufacturing facilities are SQF-certified and strictly adhere to NASC guidelines and Current Good Manufacturing Practices (cGMP) as defined by the Food and Drug Administration.Claim language across the reviewed line stays consistently in the support/help register: 'support calm behavior,' 'supports joint health, comfort and mobility,' 'help maintain the health and function of the bladder and kidneys.' Allergy + Calming shows deliberate qualifier discipline ('Occasional itching or irritation of paws,' 'Occasional scratching & sneezing'), consistent with the FDA-CVM and NASC-recommended warning language the brand commits to on its NASC Quality page. No 'clinically proven,' disease-treatment, or lifespan claim was found on any of twelve PDPs. The brand also publishes a consumer-protective review policy on PDPs: reviews 'have not been reviewed by the FDA and are not intended to diagnose, treat, cure, or prevent any disease,' with a stated right to remove reviews making disease claims. Isolated overshoots keep the pattern below near-clean: L-Lysine is marketed as 'immune-boosting' with no citation, BusyButter's copy asserts 'four effective ingredients' without published support for the effectiveness adjective, and Lawn Aid states a specific urine-chemistry mechanism without citation. Above-the-fold home-page framing is promotional and carries no inline qualifiers, though it also makes no clinical-style assertions.Isolated adjective-level overshoots ('immune-boosting,' 'effective') and uncited mechanism assertions sit above the brand's published evidence base, and no above-the-fold qualifier accompanies benefit framing. Citing support for those specific claims, or softening them to the line's prevailing register, would close the gap to near-clean discipline.We reserve the right to remove any review that claims or implies a product can diagnose, treat, cure or prevent any disease or makes similar unapproved disease claims.What the brand publishes is easy to reach: the header 'What's Inside' menu consolidates the Ingredients glossary, Never Used Ingredients pledge, and NASC Quality page one click from any page, with clear titles, and every PDP carries its full panel inline. The deeper disclosure, however, lives only in the footer FAQ — the SQF/cGMP/Vermont manufacturing statement and both third-party-testing assertions are FAQ answers a buyer must scroll an accordion to find, with no dedicated manufacturing or testing page. Two of the four evidence pillars have no destination at all: there is no science or research surface beyond the glossary's one-liners, and no team or expert surface exists anywhere (probed URLs 404; site searches for expert terms return no results). There is no consolidated trust hub tying quality claims to artifacts. At review time the site also displays a banner pausing new direct orders and referring buyers to retail partners — evidence pages remain browsable, but buyers routed to retailer listings will not encounter the FAQ or NASC content that holds the brand's substantive disclosure.Manufacturing and testing disclosure is footer-FAQ-only, and the expert and science pillars have no destination to navigate to.

Disclosure thins across the rest of the supplement line, where Triglyceride OMEGA and Zylkene report blend totals or capsule strengths rather than active-by-active amounts, the Zylkene 'clinically proven' claim shows no on-page citation, no veterinarian or formulator is named, and there is no public COA lookup or named testing laboratory.

The brand uses proprietary blends, grouped amounts, or other label conventions that prevent a buyer from reading the per-active dose on at least one product in the line. Distinct from Line Inconsistency — captures the case where actives are hidden, not where products differ.
Unnamed Experts
The brand uses "veterinarian formulated," "expert designed," or similar language without any publicly named individual, credentials, or role.
What's in it
- Audited NASC membership with an explicit cGMP statement and NAERS adverse-event participation, placing structural quality-system disclosure above the category median.
- The Flexadin Advanced chews publish active collagen amounts in milligrams with defined serving sizes and complete inactive-ingredient lists.
- The Flexadin pages cite an attributed, dated study (D'Altilio et al, 2007) and mark their headline comparative claim with a qualifying asterisk.
What's not in it
- Label disclosure varies across the line: Triglyceride OMEGA reports fish-oil blend totals without per-active EPA/DHA amounts and Zylkene gives capsule strengths without isolating the alpha-casozepine amount.
- No veterinarian, nutritionist, or formulator is named anywhere on the site; expertise is conveyed only through 'veterinarian recommended' and vet-channel framing.
- No public certificate-of-analysis lookup, named testing laboratory, or contaminant/microbial/potency panel is published, and manufacturing facilities are not named at facility, city, and state level.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsDisclosure varies materially across the supplement line. The Flexadin Advanced chews are the strongest: the standard SKU lists 'UC-II brand collagen (chicken cartilage yielding 10 mg of active undenatured collagen Type II) .......... 40 mg' and the Extra Strength SKU defines a 3-gram serving with '80 mg' UC-II brand collagen and '20 mg' total undenatured collagen, each with a complete alphabetized inactive-ingredient list. Zylkene names a single active (alpha-casozepine) and publishes a body-weight dosing table at 75 mg, 225 mg, and 450 mg capsule strengths, but does not isolate the milligram amount of alpha-casozepine itself or list inactives. Triglyceride OMEGA discloses only total fish-oil amounts by size (600 / 1,000 / 2,000 mg) plus vitamins A, D3, and E by role, with no per-active EPA/DHA milligrams, no vitamin IU figures, and no inactive list. A buyer comparing the calming and omega products cannot reconstruct the active panel to the same standard the Flexadin chews provide, which holds the modal position below the flagship tier.Triglyceride OMEGA reports a fish-oil blend total rather than per-active EPA/DHA amounts and omits vitamin IU figures and an inactive list, and Zylkene gives capsule strengths without isolating the alpha-casozepine amount. Publishing active-by-active amounts and inactive lists on the omega and calming SKUs at the standard the Flexadin chews already meet would lift the line toward the 8 tier.Small-breed capsules provides 600 mg of fish oilMechanism content is present on product pages but uneven and mostly delivered at the role level rather than as biological pathway explanation. Flexadin Advanced explains that UC-II 'works differently than other supplements containing hydrolyzed collagen peptides, glucosamine, chondroitin, or CBD' and frames a normal cartilage-repair role, which gives the joint line a clearer ingredient rationale than benefit copy alone. Zylkene identifies its active by origin — alpha-casozepine, described as a naturally occurring milk protein found in cow's milk — and frames a calming role without sedation, a partial mechanism cue. Triglyceride OMEGA attributes named roles to its nutrients ('Vitamin D3, which supports bone and muscle health') and explains why dogs and cats need supplemental omega-3s. None of these pages link to ingredient-level research libraries or a consolidated science page, so the rationale is scattered across PDPs and stops at role-and-benefit framing rather than a documented selection logic for each active.Rationale is published per-PDP at role level, with no brand-wide science page tying actives to mechanism or to ingredient research. Consolidating per-ingredient mechanism explanations with linked studies — rather than leaving the logic implicit in benefit statements on each product page — would move this toward the 8 tier.Contains alpha-casozepine, a natually occurring milk protein found in cow's milkCitation discipline is uneven across the line. The Flexadin pages do surface a real, attributable study in a footnote — 'Based on a 120-day clinical study comparing 10 mg active Type II Collagen to 2,000 mg glucosamine and 1,600 mg chondroitin (D'Altilio et al, Toxicology Mechanisms and Methods, 2007)' — and mark the headline comparative claim with an asterisk, which is genuine citation work. However, that study is ingredient-level research on UC-II collagen presented in a finished-formula context, and the page does not distinguish ingredient evidence from a finished-product trial. By contrast, Zylkene states it is 'Clinically proven to help relieve stress' with no footnote, study, author, or journal visible on the page, and the on-site search probe surfaced no science library or studies index to fill the gap. A buyer therefore sees one cited ingredient study on the joint line and an uncited clinical-proof claim on the calming line, with no consistent standard for telling ingredient research from finished-formula evidence.The single visible citation is ingredient-level and is not labeled as distinct from a finished-formula trial, while Zylkene's 'clinically proven' claim shows no underlying study. Citing the Zylkene evidence on-page and explicitly separating ingredient research from finished-product trials would lift this toward the 7-8 tiers.Based on a 120-day clinical study comparing 10 mg active Type II Collagen to 2,000 mg glucosamine and 1,600 mg chondroitin (D'Altilio et al, Toxicology Mechanisms and Methods, 2007).No individual veterinarian, nutritionist, formulator, or scientific advisor is named anywhere on the reviewed surface. The About Us page describes the corporate entity and links to About us, Satisfaction Guarantee, Sponsorships, and NASC Membership, but carries no leadership bios or expert roster. Product pages use channel and association framing rather than named expertise — Zylkene is described as 'Veterinarian recommended to help pets cope with challenging situations,' and several products state they are available 'from veterinarians' — but none attribute formulation or scientific review to a named person with credentials. An on-site search for 'veterinarian' returned the default catalog result set with no team or advisory-board page among the result types. The brand's veterinary association is positioned at the company-channel level, not through identified individuals a buyer could evaluate.The site uses 'veterinarian recommended' and vet-channel framing but names no individual veterinarian, formulator, or advisor with credentials and role. Publishing even one named expert with credentials, role, and scope of involvement would move this off the bottom of the ladder toward the 4-7 range.Veterinarian recommended to help pets cope with challenging situations like thunderstorms, car rides, separation, and moreThe brand surfaces a third-party quality-oversight signal but no finished-product testing disclosure a buyer can inspect. The NASC Membership page describes an independent audit and participation in adverse-event reporting, stating members must 'Undergo a rigorous independent audit of our facilities, labels, social media, and SOPs' and 'Participate in an adverse event reporting system (NAERS) for our products marked with the NASC seal.' That is a trade-association audit of systems and labels, not batch-level analytical testing. No public certificate-of-analysis lookup exists, no third-party testing laboratory is named, and no contaminant, microbial, or potency panel is published; the on-site search for 'certificate of analysis' returned only the default catalog set, and probed COA/testing URLs were not found. Lot-level traceability for buyers is not surfaced on any reviewed page.The NASC audit is a systems-and-labels review, not a published finished-product test program: no COA lookup, no named analytical laboratory, no contaminant/microbial/potency panel, and no lot linkage are visible. Surfacing lot-linked COAs and naming the testing lab would lift this past the 4 tier toward 7-8.Undergo a rigorous independent audit of our facilities, labels, social media, and SOPsQuality-system disclosure is the brand's strongest area. The NASC Membership page names an audited program and a recognized manufacturing standard, stating that members must 'Show that our products are manufactured in approved facilities that follow cGMPs' and noting that 'Less than 100 of the thousands of animal supplement companies in business today are audited NASC members.' The About Us page situates production within the U.S. entity ('the development, production and marketing of pharmaceutical products and health supplements') headquartered in Fort Worth, Texas. What is disclosed is the quality system (audited NASC membership plus cGMP) rather than facility identity: no manufacturing site is named at facility, city, and state level, and no ISO, SQF, HACCP, FDA-registration, or ingredient-sourcing detail is published. This matches a profile where the quality system is clearly stated but the specific facilities are held above the facility level.The quality system (audited NASC member, cGMP) is disclosed, but the manufacturing facilities are not identified by name, city, and state, and there is no sourcing-logic or additional-certification detail (ISO, SQF, HACCP, FDA registration). Naming the facilities and adding sourcing detail would move this toward the 9-10 tier.Show that our products are manufactured in approved facilities that follow cGMPsThe brand's product copy is mostly structure-and-function language ('Helps maintain joint function', 'Maintain healthy skin', 'Support a normal immune response'), and the Flexadin pages qualify their headline comparative claim with an asterisk that points to a dated, attributed study. That reflects real discipline on the joint line. The pattern is uneven elsewhere: the Zylkene page states the product is 'Clinically proven to help relieve stress without drowsy side effects' without an inline qualifier or visible citation, and Triglyceride OMEGA carries a comparative claim that it 'includes high-quality sources of omega-3 fatty acids PLUS important nutrients' and provides 'more DHA and EPA than other leading pet brands' without an on-page substantiating figure. These are isolated overshoots against the surrounding cautious copy rather than a brand-wide habit of high-confidence claims, and no disease-treatment or lifespan claims were observed.Most copy stays inside supportable structure-function language, but specific claims overshoot the visible evidence — Zylkene's uncited 'clinically proven' and Triglyceride OMEGA's unquantified 'more DHA and EPA than other leading pet brands.' Qualifying or substantiating those two claims inline would lift this toward the 8-10 tier.Triglyceride OMEGA capsules for medium breeds has more DHA and EPA than other leading pet brands of gels or capsules!What the brand does publish is reachable, but it is fragmented and several evidence pillars are simply absent. Dose panels live on individual PDPs reachable through the Products catalog, and the quality-system disclosure sits two clicks deep under About Us as the NASC Membership page; there is no consolidated 'Evidence & Trust' hub tying science, testing, experts, and manufacturing together. Two of the four pillars cannot be inspected at all: there is no named-expert page and no testing/COA page, and probed evidence URLs (/science, /research, /testing) returned the site's page-not-found template. The home page leads with corporate and careers messaging rather than buyer-facing evidence, so a buyer must navigate product-by-product and into the About sub-menu, and even then the testing and expert evidence is not present to find. Discoverability of the published material is moderate; completeness of the evidence set is the limiting factor.There is no single trust hub, the home page foregrounds corporate messaging, and the testing and named-expert pillars are absent rather than merely buried.

Native Pet
Native Pet
St. Louis, Missouri50.5/100as of 2026-05-23Disclosure GapsNative Pet is a recognizable DTC dog supplement brand with one substance-positive expert disclosure (Dr. Dan Su, board-certified veterinary nutritionist named on the home page and PDPs) and one substance-positive testing signal (Clean Label Project certification on The Daily). The brand falls into the Disclosure Gaps band because per-active doses are image-only or absent, two products use proprietary blends, marketing uses clinical-style language without underlying citations, there is no dedicated team or testing page, and manufacturing is disclosed at country level only.

The brand uses proprietary blends, grouped amounts, or other label conventions that prevent a buyer from reading the per-active dose on at least one product in the line. Distinct from Line Inconsistency — captures the case where actives are hidden, not where products differ.
Evidence Buried
The brand technically publishes meaningful science, evidence, testing, or expert disclosure, but buyers cannot reach it without dedicated effort. Evidence that exists but is hard to find counts less.
What's in it
- Names Dr. Dan Su, MS, DVM, DACVIM (Nutrition) on the home page and on product PDPs as formulator — a real board-certified specialty credential independently verifiable in the ACVIM diplomate directory.
- Clean Label Project certification on The Daily flagship is a substantive third-party signal with a defined 150+ contaminant panel — including heavy metals, pesticides, and plastics.
- Long-form blog includes ingredient-level honesty (the Glucosamine blog explicitly acknowledges thin veterinary evidence for the ingredient), and the Philosophy page articulates a six-point formulation pact with concrete commitments (max 5 inactive ingredients, no fillers, in-house formulation).
What's not in it
- No dedicated team, testing, science, or trust-hub pages on the brand surface — Dr. Dan Su has no public bio page and no documented scope/employment relationship; testing disclosure is concentrated on a single product; mechanism content is buried in blog.
- Proprietary probiotic blends on Senior Daily and Skin+Coat Chews, and no per-active mg/IU/mcg disclosure in inline PDP text across any product reviewed — supplement facts panels render only inside product images, which fails buyer-verifiability for screen readers, comparison shopping, and accessibility.
- Marketing language uses 'clinically researched,' 'clinically studied,' 'research-backed,' 'science-backed,' and 'It's been proven to' framing across home page, PDPs, and product-launch blogs without surfacing a single PubMed link, named study, or peer-reviewed citation; no finished-formula clinical trial exists on any Native Pet product.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsAcross four PDPs reviewed (The Daily flagship, Senior Daily, Allergy Chews, Skin+Coat Chews), no per-active mg/IU/mcg amounts are disclosed in inline HTML text. The supplement facts panel exists only inside product images (NP-DTC-TheDaily-6-Ingredients.jpg and equivalents). Only one CFU disclosure surfaces in inline text — Bacillus Coagulans '1 billion CFUs' on Allergy Chews — and one CFU disclosure in the 'Introducing The Daily' blog ('Probiotic Blend: 2 billions CFUs'). Two products use a PROPRIETARY BLEND label on the probiotic active: Senior Daily ('our proprietary probiotic blend,' with no constituent disclosure) and Skin+Coat Chews ('Proprietary Probiotic Blend (Lactobacillus casei, L. fermentum, L. reuteri, Enterococcus faecium)' — strains named but no amounts). Active ingredient names and biological-role descriptions ARE consistently published on every PDP — so the brand is not at tier 1. But the modal pattern is: actives named, doses image-only or absent, proprietary blends on multiple SKUs. This places the line at tier 4: 'Some products show partial dose disclosure, but proprietary blends, undisclosed amounts, or blend-only labeling dominate the line.'No per-active mg disclosure in inline HTML text across the line. Proprietary probiotic blends on Senior Daily and Skin+Coat Chews. Supplement facts panel rendered only in product images, which fails the buyer-verifiability test (image-based dose disclosure is not extractable, comparable, or screen-readable for buyers reading PDP copy). Lifting to 6 requires publishing the supplement facts panel as inline text on every PDP. Lifting to 8 requires eliminating proprietary blends across the line. Lifting to 10 requires line-wide active-by-active mg/IU/mcg disclosure with no proprietary blends.Active Ingredients: Collagen Peptides (Bovine), Collagen (Porcine), DHA (Microalgae Based Omega-3), Salmon Oil, Vitamin E, Echinacea Angustifolia, Zinc Proteinate, Hyaluronic Acid, Biotin, Proprietary Probiotic Blend (Lactobacillus casei, L. fermentum, L. reuteri, Enteroccoccus faecium)Native Pet publishes a substantial educational blog (the Blog Park) including ingredient-rationale pieces — 'Introducing The Daily,' 'Introducing Native Pet's Colostrum,' 'Glucosamine for Dogs,' 'Best Fish Oil for Dogs,' 'Taurine Supplements for Dogs.' On the PDP surface, every active ingredient gets a one-sentence role description (e.g., 'L-Carnitine: Aids fat metabolism and promotes lean muscle for a healthy, strong body composition'). The Glucosamine blog notably surfaces an HONEST critique of the evidence base ('There's very little published veterinary medicine research into whether or not glucosamine can treat joint pain'). The Philosophy page articulates a six-point pact for formulation discipline. However, the surface is structurally fragmented — there is no dedicated science page, no consolidated mechanism-content hub, no per-product Research page, and no public 'why this ingredient at this dose' framework. The PDP role descriptions are benefit-adjacent ('helps support healthy joints') rather than mechanism-explicit ('inhibits cartilage matrix degradation via X pathway'). This is tier 6: 'Meaningful public mechanism content exists, but it is incomplete, scattered across pages, flagship-only, or requires buyer interpretation to connect ingredients to roles.'No dedicated science page, no consolidated mechanism hub, no per-product Research/Science page. Ingredient rationale is reachable only by searching the blog. PDP role descriptions are benefit-language ('helps support'), not mechanism-explicit. The Glucosamine blog's honest evidence-skepticism does not propagate to the PDP for The Daily. Lifting to 8 requires a dedicated Science / Research / How-It-Works landing page that consolidates ingredient rationale and mechanism across the line.We turned to trusted vet nutritionists, veterinarians, and food scientists to determine the most effective way to formulate. Our first question was: what common health issues are we looking to solve?The brand routinely uses clinical-style and evidence-style language without surfacing the underlying evidence. Home page: 'Clinically researched ingredients in every formula.' The Daily PDP: 'Made with clinically studied, high-quality ingredients.' Retail page: 'vet-approved, research-backed supplements.' Colostrum blog: 'Research indicates that even a modest daily dose can elevate plasma IgG... It's been proven to: Boost Immune Function... Research has shown that the right dosage can significantly improve both immune response and gut health' — no named study, no journal, no PubMed link, no author. No published finished-formula clinical trial exists on any Native Pet product. No public studies page, no evidence library, no citation index. The brand's customer-survey self-report ('86% of pet parents reported an improvement in their dogs' quality of life') is presented in outcomes-data framing but is buyer-survey methodology, not a clinical trial. The honest counter-example — the Glucosamine blog — actually undermines the broader 'clinically researched ingredients' claim, since glucosamine is named on The Daily as clinically studied while the brand's own blog acknowledges thin evidence. This is tier 3: between 'Uses 'clinically tested' / 'clinically proven' or similar language with no underlying citation visible to buyers' (1) and 'Uses clinical-style language without surfacing the underlying studies, or routinely borrows ingredient-level research as finished-formula evidence'No PubMed links, no peer-reviewed citations, no published finished-formula trials, no public evidence library distinguishing ingredient-level from finished-formula evidence. 'Clinically studied,' 'clinically researched,' 'research-backed,' 'science-backed,' and 'It's been proven to' language is used routinely without underlying evidence surfacing. Lifting requires either (a) publishing a finished-formula clinical trial or (b) tightening marketing language to remove unbacked 'clinically tested' framing and replace with cited ingredient-level evidence with explicit ingredient-vs-finished-formula distinction.Clinically researched ingredients in every formulaDr. Dan Su, MS, DVM, DACVIM (Nutrition) is named on the home page and on every reviewed product PDP as the formulator of 'Every Native Pet formula.' DACVIM (Nutrition) is a real, board-certified credential (Diplomate, American College of Veterinary Internal Medicine — Nutrition specialty), independently verifiable in the ACVIM diplomate directory. This is a substance-positive disclosure that materially separates Native Pet from competitors who use 'veterinarian-formulated' framing with no named individual. However: there is no dedicated bio page for Dr. Dan Su on Native Pet's site (probed /pages/dr-dan-su returns 404). Scope of involvement is framed only as 'developed by' — no disclosure of whether he is an in-house employee, paid consultant, or external advisor; no timeline of involvement; no documented role for review, audit, formulation lead, or scientific advisory; no separation of which products he formulated versus reviewed versus contributed to. The Philosophy page references 'one of only 40 Board-Certified Vet Nutritionists in the USA' without naming additional team members. No other veterinarians, nutritionists, food scientists (referenced in blog), or scientific advisors are named publicly. This places the brand at tier 7: 'Brand references veterinarian formulated or expert designed with at least one name visible somewhere on the site, but credentials, role, or scope remain vague' — with credentials slightly above tier 7 (DACVIM is a real specialty board) but scopeNo dedicated bio page for Dr. Dan Su. No disclosure of employment relationship (employee, consultant, advisor). No documented scope-of-involvement language (formulated / reviewed / safety-audited / contributed commentary, with role discipline). No other named veterinary contributors, nutritionists, food scientists, or scientific advisors despite the 'team of experts' reference in blog content.

The Daily flagship PDP states: 'The Daily is the only pet product to be Clean Label Project certified... A formula that's been 3rd party verified and tested for over 150+ harmful contaminants like pesticides, plastics, heavy metals, and other toxins.' Clean Label Project is a real third-party program with a defined contaminant panel — substance-positive on the flagship. Skin+Coat Chews PDP carousel includes NASC badges in image filenames (NP-Skin_Coat-Carousel-3-Benefits-NASC.jpg) — NASC participation is visually surfaced but not as inline-text quality-system disclosure. However: no other named third-party laboratory beyond the Clean Label Project program. No COA lookup tool on the brand. No per-lot traceability. No public COAs for any product, including The Daily. The testing claim '150+ contaminants' is exclusive to The Daily — the other 26+ products in Native Pet's line carry no comparable testing disclosure on their PDPs. No microbial or potency panel disclosed in inline text. This is tier 5: 'Some testing signals exist, but the buyer cannot verify enough to distinguish a real testing program from marketing language.'No dedicated testing/quality page (probed /pages/testing returns 404). No COA lookup. No per-lot traceability. No named third-party laboratory beyond the Clean Label Project certification name. No microbial or potency panel disclosed in inline text.

The Retail page states: 'Made in the USA — All of our products are expertly manufactured with care and intention right here in the USA.' Country level only — no facility name, no city, no state. NASC participation is surfaced visually in product image carousels on Skin+Coat Chews (NP-Skin_Coat-Carousel-3-Benefits-NASC.jpg) — NASC member status is inferable but is not stated in inline text on any dedicated page; the brand's name appears in the NASC member directory which can be independently verified, but no link to the directory entry is published on Native Pet's surface. The Philosophy page states 'we always develop & fully own the formulation process — everything is done 100% in-house' but does not name the manufacturing facility (formulation ownership ≠ facility identity). No cGMP language is surfaced in inline text. No HACCP, FDA registration, SQF, or ISO certifications disclosed. Sourcing logic is partly disclosed editorially (wild-caught salmon, grass-fed beef, organic chicken — supplier framing rather than supplier identity). This is tier 5: between tier 4 ('Quality system language is present but generic, with no named facility, certification body, or sourcing detail') and tier 6 ('Meaningful manufacturing language exists, but it is incomplete, scattered, or requires buyer interpretation'). NASC visual badge lifts above tier 4; absence of inline cGMP/facility disclosure holds at tier 5.No facility name, city, or state disclosed.

Lifting to 10 requires facility name, city, state, plus disclosed sourcing logic with named suppliers.Made in the USA — All of our products are expertly manufactured with care and intention right here in the USANative Pet's claim discipline is mixed. Substance-positive: PDP copy uses 'designed to support,' 'helps maintain,' 'helps support' framing rather than disease-treatment language. Hero copy is restrained ('daily supplements for a healthier life / Vet-formulated, whole-food formulas designed to support digestion, joints, skin, immunity, and vitality'). The brand avoids explicit cure/treatment claims. The Glucosamine blog actively documents evidence limits. Substance-negative: the brand uses 'clinically researched,' 'clinically studied,' 'research-backed,' 'science-backed,' and 'It's been proven to' language above-the-fold and across the PDP surface with no underlying citation. Colostrum blog uses 'It's been proven to: Boost Immune Function' framing. Customer-survey self-report ('86% of pet parents reported an improvement... 85% saw a positive improvement in gut health and digestion. 80% saw an improvement in skin health') is presented as outcome data, which approaches over-claim territory for what is methodologically a satisfaction survey. No inline 'not a substitute for veterinary care' qualifier on the home page hero or PDP hero. This places the brand at tier 6: 'Meaningful claim discipline exists, but it is uneven across the surface, flagship-only, or relies on buyer interpretation to know what is qualified.'Unbacked 'clinically researched / clinically studied / research-backed / science-backed' language across PDPs and home page. 'It's been proven to' framing in product-launch blogs. No inline 'not a substitute for veterinary care' qualifier above-the-fold. Customer-survey self-report framed as outcome data. Lifting to 8 requires either (a) surfacing the actual studies behind 'clinically studied' framing or (b) tightening to 'researched ingredients' / 'evidence-aware ingredient selection.' Adding an inline qualifier to all above-the-fold hero copy would also lift.Made with clinically studied, high-quality ingredientsFrom the home page, the buyer reaches: (1) Dr. Dan Su's name + credentials inline on the home page itself (zero clicks); (2) ingredient role descriptions and the Clean Label Project claim on The Daily PDP in one click; (3) Philosophy page from the footer in one click.

Mechanism content is reachable only by searching the Blog Park manually. Verifying the brand's 'clinically researched ingredients' claim requires the buyer to either (a) trust the language unverified or (b) leave the site to search PubMed independently. The four evidence pillars are NOT each addressable in one click — only two are (named expert via home page, partial testing claim via flagship PDP). Science is buried in blog; manufacturing is one line on Retail page; team has no surface at all.

St. Louis, MO48.5/100as of 2026-06-13Sparse Public EvidencePurina Pro Plan Veterinary Supplements discloses per-active doses well across most of its line — full mg panels on soft chews, per-strain CFU on probiotic powders — and keeps its own marketing comparatively measured. The brand-direct site is built for purchasing rather than verification: it names the NASC Seal on two SKUs and U.S. company-owned manufacturing in aggregate, but publishes no named experts, no study citations behind its efficacy claims, and no product testing or lot-linked COA. Substance gaps cluster on citation, expert identity, and testing rather than on labels.
Public Evidence System Named Vet ReviewerIngredient RationaleDisease-Claim-FreeNASC Member Finished-Formula Trial Named Mfg FacilityWorth NotingUnnamed Experts
The brand uses "veterinarian formulated," "expert designed," or similar language without any publicly named individual, credentials, or role.
What's in it
- Soft-chew SKUs disclose full per-active milligram panels (Joint Care and Skin Care itemize every active with exact mg) and the probiotic powders publish per-strain CFU with defined serving sizes — strong, format-appropriate label disclosure across most of the line.
- Marketing on the brand's own pages is generally measured, using hedged verbs, six-week onset qualifiers, and a comparator-baseline hydration claim, and it omits the aggressive efficacy statistics that appear in third-party retail copy.
- The Skin Care and Multi Care pages name the NASC Quality Seal (Certified by the National Animal Supplement Council), and the 'Our Difference' page discloses U.S. company-owned manufacturing with an aggregate daily quality-check figure.
What's not in it
- No veterinarian, nutritionist, or formulator is named anywhere on the brand-direct site; expert involvement is presented only as an anonymous 'collaboration among Purina nutritionists, researchers and veterinarians.'
- Efficacy language such as 'proven to promote intestinal health' and 'shown to help dogs maintain calm behavior' is not paired with accessible study citations, and the pages do not distinguish strain-level research from finished-formula evidence.
- There is no public COA lookup, no named third-party laboratory, and no disclosed contaminant/microbial/potency panel; the 311-URL sitemap contains no science, testing, or named-expert page.

The probiotic powders and sachets disclose per-active colony counts with serving sizes — FortiFlora 'Active Ingredients per Sachet (1.0 g): Enterococcus lactis SF68 1x10^8 CFU,' Calming Care 'Bifidobacterium Longum BL999 1x10^9 CFU,' Multi Care '2 x 10^8 CFU/g' alongside 315 mg and 15 mg components. The dispersion sits at the hydration line and the synbiotic prebiotic: Hydra Care uses a feed-style Guaranteed Analysis (Crude Protein (Min) and similar min/max ranges) rather than itemized per-osmolyte amounts, and FortiFlora PRO Synbiotic Action names psyllium prebiotic fiber qualitatively without a per-serving gram figure in its active table. The brand also uses 'proprietary microencapsulation process' and 'Proprietary use of probiotic strain BL999' framing, which describes process rather than obscuring the disclosed active. Scored against the modal SKU, the line clears strong per-active disclosure but is held below the topHydra Care does not itemize per-osmolyte amounts (it relies on a min/max Guaranteed Analysis), and FortiFlora PRO Synbiotic Action discloses its psyllium prebiotic only qualitatively rather than as a per-serving gram amount. Bringing the hydration line and the synbiotic prebiotic to the same per-active disclosure standard the soft chews and probiotic CFU panels already meet would lift the score toward an 8 or 9.Active Ingredients per Sachet (1.0 g):Ingredient rationale exists on the product pages but stays at a surface, role-stating level and is scattered across individual PDPs rather than consolidated. Skin Care explains that 'Omega-6 (linoleic acid) and omega-3 (EPA and DHA) fatty acids... help the skin maintain its natural protective barrier' and that vitamin E 'provides antioxidant support,' which connects named actives to plausible roles. FortiFlora PRO Synbiotic Action explains a prebiotic mechanism: psyllium fiber is described as included 'to stimulate the growth of specific bacteria, including Lactobacillus and Bifidobacterium species.' Joint Care frames its actives as 'important building blocks to help maintain healthy cartilage and joints,' and Hydra Care describes osmolytes as 'intended to aid in the absorption of water at a cellular level.' What is missing is depth and consistency: the probiotic strains (Enterococcus lactis SF68, Bifidobacterium longum BL999) are presented largely in benefit language ('proven to promote intestinal health and balance,' 'shown to help dogs maintain calm behavior') rather than with an explained biological mechanism, and there is no brand-level ingredient-science page or per-ingredient encyclopedia. A buyer must read each PDP and infer the logic. The content qualifies as meaningful but incomplete and interpretation-dependent.Mechanism content is scattered across individual PDPs and leans on benefit phrasing for the flagship probiotic strains rather than explaining how SF68 or BL999 act. A consolidated ingredient-science page giving a per-active biological role for the probiotics — not only the soft-chew nutraceuticals — would move this from a scattered 6 toward a 7 or 8.Contains prebiotic fiber (psyllium) to stimulate the growth of specific bacteria, including Lactobacillus and Bifidobacterium speciesThe brand uses clinical-style efficacy language but does not surface the underlying studies on its pages. FortiFlora states it 'contains a strain proven to promote intestinal health and balance'; Calming Care says it 'contains a strain of beneficial bacteria shown to help dogs maintain calm behavior'; Hydra Care is 'shown to increase feline total fluid intake.' None of these 'proven' or 'shown to' statements links to a citation, names an author or journal, or distinguishes whether the support is ingredient/strain-level research or a finished-formula trial on the specific product. The only attributed reference found on a supplement PDP is a market-research source for a recommendation claim — 'Number 1 veterinarian-recommended dog probiotic brand to support digestive health (Relevation Veterinary Tracker, 2023)' — which speaks to recommendation share, not clinical efficacy. The full 311-URL sitemap contains no clinical-evidence, study-library, or research-citation page, and the science attribution defers to an unnamed internal collaboration. A buyer cannot read the studies behind the efficacy language from the brand-direct surface.The 'proven'/'shown to' efficacy claims are not paired with accessible citations, and the pages do not state whether support is strain-level or finished-formula. Publishing the referenced studies (with author and journal) and explicitly labeling each claim as ingredient-level versus finished-product evidence would lift this several tiers.Number 1 veterinarian-recommended dog probiotic brand to support digestive health (Relevation Veterinary Tracker, 2023)Expert involvement is asserted but kept anonymous. Product pages state that 'The science behind our products represents a collaboration among Purina nutritionists, researchers and veterinarians,' and the supplement landing page describes Multi Care as 'brought to you by experts in probiotics and digestive health.' No individual veterinarian, nutritionist, formulator, or scientific advisor is named anywhere on the brand-direct surface, and no credentials, roles, or biographies are provided. A full review of the 311-URL sitemap and direct probes of common paths (/about-us and similar) found no team, expert, or advisory-board page. The 'DVM' strings present in the page source resolve to CSS style identifiers, not credential disclosures, and the recurring 'veterinarian-recommended' language is a market claim rather than a named expert. The brand therefore relies on collective, unnamed expert framing.No veterinarian, nutritionist, or formulator is identified by name, credential, or role on the brand-direct surface; expertise is presented only as an anonymous collective. Naming at least one credentialed expert with their role and scope — reachable from primary navigation — would move this toward the upper tiers.The science behind our products represents a collaboration among Purina nutritionists, researchers and veterinarians.The brand-direct surface offers no buyer-usable finished-product testing transparency. There is no COA lookup tool, no lot-linked report, no named third-party laboratory, and no published contaminant, microbial, or potency panel anywhere across the reviewed pages or the 311-URL sitemap. The strongest testing-adjacent signals are an aggregate corporate quality statement on the 'Our Difference' page — 'Over 100,000 quality & safety checks are performed per day across all U.S. owned and operated manufacturing facilities' — and the probiotic PDPs' assurance that each unit 'contains a guaranteed level of live microorganisms.' Neither connects to a specific lot, names a lab, or surfaces a report a buyer could inspect for the bottle they intend to purchase. The NASC Quality Seal cited on the Skin Care and Multi Care pages implies independent program oversight but is not a product-specific COA. Direct probes for /testing and /certificate-of-analysis returned 404.There is no public COA lookup, no named testing laboratory, and no disclosed contaminant/microbial/potency panel tied to specific lots. A lot-linked COA portal with a named third-party lab and panel scope would be required to move beyond generic quality-check language.Over 100,000 quality & safety checks are performed per day across all U.S. owned and operated manufacturing facilities.Manufacturing disclosure is meaningful at the country and program level but does not reach facility identity, and the quality-system signal is inconsistent across the line. The 'Our Difference' page states that 'Over 100,000 quality & safety checks are performed per day across all U.S. owned and operated manufacturing facilities,' establishing that production is U.S.-based and in company-owned plants. The clearest certification disclosure is the NASC Quality Seal, but it appears on only two of the reviewed SKUs — the Skin Care soft chews, which state the product earned the 'NASC Quality Seal... Certified by the National Animal Supplement Council (NASC),' and Multi Care feline; the probiotic powders (FortiFlora, Calming Care, Hydra Care) carry no NASC statement. Skin Care also notes the supplement is 'produced in USA facilities.' No facility is named at the city/state level, no cGMP, FDA-registration, HACCP, SQF, or ISO certification is stated for the supplement line, and sourcing logic is not disclosed. The disclosure is therefore real but scattered and requires the buyer to read individual SKU pages to find the only named certification.Manufacturing is disclosed only at country level ('U.S. owned and operated... facilities') with no facility named at city/state, and the NASC Quality Seal — the single named certification — is surfaced on only part of the line rather than line-wide. Naming the facility and applying a consistent certification statement (NASC/cGMP/FDA) across every SKU would move this toward an 8.NASC Quality Seal, meaning they are Certified by the National Animal Supplement Council (NASC) for meeting the highest quality and compliance standards for pet supplements.On its own pages the brand's marketing is generally measured and avoids disease-treatment promises, but a few high-confidence phrasings run ahead of the on-page evidence. Restraint is visible in the use of hedged verbs ('shown to help dogs maintain calm behavior,' 'intended to aid in the absorption of water'), explicit qualifiers ('May take six weeks to see results'), comparative framing with a stated baseline ('shown to increase feline total fluid intake (when compared to cats consuming only water in addition to dry feeding)'), and Cautions sections instructing buyers to 'consult your veterinarian.' Notably, the aggressive '90% of dogs' efficacy statistic that circulates in third-party retail copy does not appear on the brand-owned Calming Care PDPs. Against that, FortiFlora describes a strain 'proven to promote intestinal health and balance' without an on-page citation, and the headline 'Number 1 veterinarian-recommended dog probiotic brand' rests on a market-research tracker rather than a clinical reference. The pattern is disciplined but uneven, with 'proven' language and broad superlatives carried above the supporting evidence on the flagship.The flagship's 'proven to promote' phrasing and the 'Number 1 veterinarian-recommended' superlative are stated without an inline citation to the evidence behind them. Qualifying 'proven' language with an accessible study reference and clearly sourcing the recommendation claim above the fold would lift this toward an 8 or 9.shown to increase feline total fluid intake (when compared to cats consuming only water in addition to dry feeding).The brand-direct site is built for purchasing rather than evidence inspection, so several of the four trust pillars cannot be reached at all. Primary navigation is commerce-first (Shop Dog, Shop Cat, Offers, Rewards) with a single brand page, 'Our Difference,' standing in for the trust hub. That page presents generic quality and research language and routes its 'Discover More' / 'Learn More' links off-site to purina.com corporate pages rather than to supplement-specific science, testing, or facility disclosures. Per-active dose panels are reachable on each PDP, and the NASC Seal is findable on two SKU pages, so label and partial quality evidence are accessible. But there is no science page, no testing or COA page, and no named-expert page anywhere in the 311-URL sitemap, and direct probes of common paths returned 404. Two of the four pillars (testing and named experts) are effectively unreachable on-site, and manufacturing detail is held to a single aggregate sentence, so a buyer cannot inspect the full evidence set before purchase without leaving for corporate Purina pages.Testing/COA and named-expert evidence are not reachable from the brand-direct site at all, and the deepest quality and research content redirects off-site to purina.com. A consolidated, on-site trust hub linking science, testing, experts, and facility disclosure within three clicks would move this well above a 4.Over 100,000 quality & safety checks are performed per day across all U.S. owned and operated manufacturing facilities.Reviewed Jun 13, 2026Sources: 14 sources reviewed18PPVPurina Pro Plan Veterinary SupplementsNestlé Purina PetCare CompanyPurina Pro Plan Veterinary Supplements discloses per-active doses well across most of its line — full mg panels on soft chews, per-strain CFU on probiotic powders — and keeps it...Unnamed Experts48.5/100Sparse Public Evidence - 19RankDV

Crittenden, Kentucky45.5/100as of 2026-06-13Sparse Public EvidenceDinovite publishes consistent guaranteed-analysis panels and full ingredient lists across its line, with exact omega doses available in its FAQ and per-active milligrams on the dental sub-line. Disclosure stops at the label: the brand names no laboratory, publishes no COAs, discloses no quality system beyond made-in-USA badges, and its dental line's clinical claims cite no readable studies. One named R&D nutritionist appears on the dental PDPs; the core line's experts remain unnamed.

The brand uses "clinically tested," "clinically proven," "study-backed," or trial-adjacent language without surfacing finished-formula or properly qualified ingredient-level evidence.
Unnamed Experts
The brand uses "veterinarian formulated," "expert designed," or similar language without any publicly named individual, credentials, or role.
What's in it
- Every product in the line publishes a complete ingredient list and a guaranteed-analysis panel with quantified minimums — zinc 2 mg/gm, vitamin E 12 IU/gm, taurine 10 mg/gm on the cat formula, total microorganisms 1.0x10^8 CFU/gm — plus stated scoop weights, applied consistently from flagship to puppy SKU.
- The dental sub-line reaches the brand's strongest disclosure tier: per-active milligrams (250 mg Canine Oral Health Postbiotic per chew; 253-284 mg per powder scoop) and a named formulator, Dr. Inke Paetau-Robinson, Senior Nutritionist, R&D, quoted on both PDPs.
- The FAQ volunteers buyer-protective specifics that are rare for legacy direct-response brands: exact DHA/EPA doses per teaspoon for both oils, a kelp-thyroid caution, and an explicit statement that the dental clinical studies were conducted with the postbiotic ingredient.
What's not in it
- No public testing disclosure exists at any level — no named laboratory, no COA access, no lot traceability, and no testing or quality page; probed URLs return 404 and brand copy contains no third-party-testing language.
- No quality-system disclosure — manufacturing is held at made-in-USA badge level plus an unnamed 52,000-square-foot facility reference, with no cGMP, NASC, FDA-registration, or facility identity published.
- The dental line's 'clinically proven' and '3 clinical trials' claims, and the flagship's comparative statistics ('83% say Dinovite works better'), are published without any citation, methodology, or readable study.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsDisclosure across the core line is consistent in format but stops at guaranteed-analysis level. Every reviewed SKU publishes a complete ingredient list and an AAFCO-style panel: Dinovite for Dogs discloses zinc at 2 mg/gm minimum, vitamin E at 12 IU/gm, omega-3 at 5%, and total microorganisms at 1.0x10^8 CFU/gm with the scoop weight stated ('Each dog scoop contains about 8 gm.'); Dinovite for Cats adds taurine at 10 mg/gm; SuprOmega states DHA 9% / EPA 10% minimums with vitamin E at 60 IU/tsp. Exact omega doses exist but live in the FAQ rather than on the panels — 13.5 mg DHA / 15 mg EPA per teaspoon for LickOchops, 117-180 mg/tsp ranges for SuprOmega. Botanical and functional ingredients (ground flax seed, dried kelp, yeast culture, fructooligosaccharide, yucca) carry no amounts, and probiotic CFU is an aggregate, never per-strain. The dental sub-line discloses per-active milligrams (Canine Oral Health Postbiotic 250 mg per chew; 253-284 mg per powder scoop) but wraps its remaining actives in a 'Proprietary Oral Health Blend' of 245-1,180 mg with components named, not quantified. A buyer can reconstruct approximate per-serving amounts from the per-gram minimums and stated scoop weights, but the brand never does that arithmetic on the page.No product publishes a per-serving, per-active panel in mg/IU/CFU — quantification is held at guaranteed-analysis minimums per gram or percent, and the exact omega doses sit in the FAQ rather than on the product pages. Per-strain CFU counts, amounts for the botanical actives, and per-component disclosure inside the dental Proprietary Oral Health Blend would lift the line toward the 7-8 tier.The DHA is 13.5mg. per teaspoon. The EPA is 15mg. per teaspoon.'What Is Dinovite?' — the brand's closest analogue to a science page, reachable from primary navigation — organizes the core formula's ingredients by health goal and assigns each a one-line role: 'Omega 3 for dogs helps support immune function. Essential for healthy and hydrated skin.'; zinc methionine complex is described as a highly absorbable form of zinc for skin, coat and immune support; pre- and probiotics 'balance good gut bacteria and promote stool quality.' The FAQ goes deeper in places — it defines postbiotics as 'active compounds produced when probiotics digest prebiotics,' explains Volatile Sulfur Compounds as the measured marker behind the dental claims, and answers ingredient-logic questions such as why yeast culture is included. The dental PDPs carry the line's most explicit mechanism framing: the chews 'address the oral microbiome, the true root of bad breath and plaque.' No rationale anywhere is connected to a citation — there are no PubMed links, journal names, or study references on any page reviewed. Core-line PDP copy stays in benefit register ('Promotes a strong immune system, Supports digestion'), so the depth a buyer can reach depends on which page they happen to open.Rationale exists at one-line depth and is scattered across the approach page, FAQ, and dental PDPs rather than consolidated, and none of it cites ingredient-level research. A per-ingredient resource explaining mechanisms with linked studies for the core line's meaningful actives (probiotic strains, zinc methionine, omegas, kelp) would move this to the 7-8 tier.Omega 3 for dogs helps support immune function. Essential for healthy and hydrated skin.The dental sub-line is built on clinical-register language with no readable study behind it: 'Clinically proven to reduce plaque- and tartar-causing microbes in just 7 days,' 'These vet-developed, clinically proven chews,' 'Powered by the most clinically validated postbiotic on the market.', and a results block headed '3 clinical trials that prove industry-leading efficacy.' The only sourcing on either dental PDP is an asterisked footnote — 'Results based on three clinical studies conducted from May - November 2024' — which dates the studies but names no investigator, journal, registry, or document, and links to nothing. Quantified outcomes ('Up to 98% disruption of plaque-forming biofilms in lab studies,' '85% Average reduction of odor-causing compounds in lab studies') are equally uncited. The FAQ supplies the surface's one piece of citation discipline by attributing the work to the ingredient rather than the finished product: 'Clinical studies with the postbiotic that is present in the Dinovite Dental Powder have shown that most pet parents notice an improvement in bad breath within 7 days.' The core supplement line avoids clinical language entirely, relying on customer statistics instead. At review time a buyer cannot read any referenced study or determine whether the trials were conducted on the finished chews, the powder, or the supplier's postbiotic ingredient.Every clinical claim on the dental line is unverifiable at review time: no author, journal, registry entry, or study document is published, and the finished-product-versus-ingredient question is answered only obliquely in the FAQ. Publishing the three 2024 studies — or even summaries with named investigators and the tested substrate — and qualifying the PDP claims accordingly would lift this score materially.Results based on three clinical studies conducted from May - November 2024One named expert appears on the brand surface: Dr. Inke Paetau-Robinson, captioned 'Senior Nutritionist, R&D - Cats and Dogs,' is quoted on both dental PDPs as the formulas' designer — 'We designed this chew to address the oral microbiome, the true root of bad breath and plaque.' Her degree, institution, and biography are not disclosed anywhere on the site, and she is not connected to the core supplement line. That core line's expert language is anonymous: the approach page leads with 'Expert-Formulated, Wallet-Friendly,' the dental pages state 'Formulated by PhDs and reviewed by veterinarians.' without names, and the FAQ says the dental chews were 'created with dogs in mind by animal nutritionists and veterinarians.' Founder Ed Lukacevic is named on Our Story as a 'professional dog breeder and trainer' — a disclosed originator, but not a veterinary or nutrition credential. There is no team, experts, or advisory-board page: /pages/team, /pages/our-team, /pages/about-us, /pages/experts, and /pages/veterinarians all return 404, and the crawler's expert sweep found zero credentialed names outside the dental PDPs. The blog's named people (DogTV's Chrissy Joy and a vet med professional identified only as 'Walter') are endorsers, not formulators.The single named expert carries no published credentials or biography, is reachable only by opening the dental PDPs, and does not cover the flagship line, whose 'animal nutritionists and veterinarians' remain unnamed. A team page naming the PhDs and veterinarians behind each formula — with credentials, roles, and scope — would lift this to the 8-9 tier.We designed this chew to address the oral microbiome, the true root of bad breath and plaque.No public finished-product testing disclosure exists on the reviewed surface. There is no testing or quality page — /pages/testing, /pages/quality, /pages/coa, /pages/lab-results, and /pages/certificates-of-analysis all return 404 — no named laboratory, no COA lookup, and no batch or lot language anywhere: a full-text sweep of the home page, FAQ, approach and story pages, and seven PDPs found zero brand-copy occurrences of 'third-party,' 'COA,' 'batch,' 'lot,' or 'quality control.' The only laboratory language on the site is efficacy-framed and attached to the dental sub-line ('Lab studies show up to 98% disruption of plaque-forming biofilms'), which speaks to ingredient performance rather than contaminant, microbial, or potency verification of production runs. The FAQ's quality posture is an ingredient assertion — 'Our supplements are made with premium-quality ingredients, free from fillers and additives' — and the home page's trust strip cites longevity ('Over 1,000,000 Pets Helped') rather than test results. Nothing on the surface connects any product or batch to a verifiable laboratory document.The gap is not partial access but the absence of any disclosed testing program: no named lab, no panel scope, no lot-level document. A single public page describing finished-product testing with a named third-party laboratory would move this to the 4-5 tier; lot-linked COA access across the line would be required for 8 and above.Our supplements are made with premium-quality ingredients, free from fillers and additivesManufacturing disclosure is held at country level: 'made in the usa' badges appear on the Dinovite for Dogs, Cats, Puppies, and SuprOmega PDPs, and the dental PDPs pair 'Made in USA' with 'Globally sourced ingredients.' The Our Story page adds a historical fragment — 'In 2007, Dinovite expanded from its humble origins to a 52,000 square foot manufacturing facility' — but the facility is never named or located beyond the founding narrative's Kentucky farm. No quality system is disclosed anywhere: a term sweep of the reviewed pages found no cGMP, NASC, FDA-registration, HACCP, SQF, or ISO language, /pages/manufacturing and /pages/sourcing return 404, and the brand displays no NASC Quality Seal. Sourcing detail is limited to ingredient-origin naming on the oils ('Wild Pollock Oil, Alaskan Salmon Oil'; menhaden fish oil) and the generic dental-line phrase. Even the country-level claim is not uniform — the LickOchops and Salmon Oil Blend PDPs carry no made-in-USA badge.No quality system is disclosed at all — naming cGMP status, FDA facility registration, or NASC membership would reach the 8 tier. Identifying the 52,000-square-foot facility by name, city, and state, with its certifications and a sourcing policy, would be required for 9-10.In 2007, Dinovite expanded from its humble origins to a 52,000 square foot manufacturing facilityThe brand's most visible pages carry high-confidence claims with no published substantiation. The flagship PDP headlines 'Tackle itching, paw licking, hot spots, and seasonal allergies with one easy-to-use nutritional supplement' and displays unsourced comparative statistics — '83% say Dinovite works better than other products they tried!' and '4 out of 5 customers saw results in the first 3 months!' — with no methodology. The dental sub-line repeats 'clinically proven' across both PDPs and reaches for a market-wide superlative ('Powered by the most clinically validated postbiotic on the market.') without citation, and Our Story labels its testimonial base 'Proven Results.' The reviews page is a before/after transformation gallery with condition-referencing titles such as 'Dog Hot Spot Healing,' qualified only by 'Results may vary.' Counterweights are real: the cats PDP states 'This supplement is not intended to treat or cure any disease, and it is not recommended for cats with thyroid issues,' the FAQ volunteers a kelp-thyroid caution and routes buyers to their veterinarian throughout, and routine product copy stays in hedged 'helps support' register. The observed pattern is mixed marketing convention rather than disease-treatment claims — but the highest-confidence language on the surface is exactly where no citation is published.Score is held down by the recurring uncited 'clinically proven' framing on the dental line, unsourced comparative statistics on the flagship PDP, and condition-referencing before/after titles on the reviews gallery. Publishing the underlying studies and survey methodology, or qualifying these claims inline where they appear, would support a 6-7.83% say Dinovite works better than other products they tried!What the brand publishes is mostly reachable, but the evidence surface itself is thin and uneven. Label panels and full ingredient lists sit directly on each PDP (two clicks from home via My Dogs / My Cats), and the top-navigation 'What Is Dinovite?' page reaches ingredient-role content in one click. The deeper verifiable details demand dedicated effort: exact DHA/EPA milligram doses and the ingredient-level attribution of the dental studies are buried inside a footer-linked FAQ spanning well over a hundred questions, and the only named expert appears solely on the two dental PDPs. Two of the four evidence pillars cannot be reached at any click depth because they are not published — there is no testing, COA, team, or manufacturing page (each probed URL returns 404), and no consolidated trust hub exists. The home page's trust strip ('Over 1,000,000 Pets Helped,' 'Over 20 Years in Business') points to longevity rather than inspectable evidence, so a buyer's pre-purchase verification path ends at the label panel and the FAQ.There is no consolidated evidence or trust page; dose specifics live in a very long FAQ rather than on the panels, and the expert and clinical-study trails dead-end on the dental PDPs. A single hub linking label panels, study summaries, named experts, and manufacturing detail — reachable from primary navigation — would lift this toward 7-8.Traditional food alone may be missing vital nutrients your pet needs.

Zesty Paws
Zesty Paws LLC
United States42.5/100as of 2026-05-23Sparse Public EvidenceZesty Paws is a high-distribution, mass-market pet supplement brand with strong trust-badge presence (NASC, B Corp via parent H&H Group, 380,000+ reviews) but a shallow public evidence layer. Across the eight rubric criteria, the brand's modal pattern is anonymous-collective expert language, proprietary-blend dose labeling, country-level manufacturing disclosure, branded-ingredient mentions without underlying citations, and CBD-only testing transparency. The Native Canine Probiotic landing is a markedly more disciplined evidence page that does not yet generalize to the broader catalog.

The brand uses proprietary blends, grouped amounts, or other label conventions that prevent a buyer from reading the per-active dose on at least one product in the line. Distinct from Line Inconsistency — captures the case where actives are hidden, not where products differ.
Unnamed Experts
The brand uses "veterinarian formulated," "expert designed," or similar language without any publicly named individual, credentials, or role.
What's in it
- Honest qualifier discipline on the Native Canine Probiotic landing — the brand publicly states the full RCT is forthcoming (H1 2026) rather than implying a finished study already exists, and labels small-sample data as preliminary.
- NASC Quality Seal membership and GMP certification are both disclosed in narrative form, plus a WCAG 2.2 / ADA accessibility statement with a named tooling partner (TestParty), giving the brand a meaningful baseline of structural trust signals.
- 'Clinically studied' language is correctly attached to specific branded ingredients (Suntheanine on Calming Bites, DE111 on Probiotic Bites, OptiMSM on Mobility) rather than to the finished product — a meaningful piece of claim discipline relative to typical category practice.
What's not in it
- No named DVM, formulator, scientific advisor, or board member is identified anywhere on the public surface — despite 'Vet-trusted' framing, a 'Vet Strength' product line, and a 'For Veterinary Professionals' nav placement that uses 'developed with scientific and veterinary input' language.
- The 'Product Test Results' page in the footer is scoped exclusively to legacy CBD SKUs and returns 'Lot number doesn't exist' for the active catalog; the active 80+ supplement SKUs have no lot-linked COA program, no named third-party laboratory, and no contaminant or microbial panel disclosure.
- Per-active dose disclosure is inconsistent across the line: the dog 8-in-1 partial-breaks out two actives, Hip & Joint uses a single 1510 mg proprietary blend with no per-active split, Probiotic Bites discloses blend-level CFU only, Calming Bites and the Cat 8-in-1 Mousse list ingredients with no doses at all.
Why this scoreitap any criterion for evidence— —Why this scoreWhat's missingBrand's own wordsModal-product disclosure pattern is proprietary-blend with partial active break-out. Across five flagship PDPs sampled, dose disclosure is materially inconsistent. The dog 8-in-1 Multivitamin Bites discloses two proprietary blends at blend-level mg only (Proprietary Mobility Blend 550 mg, Proprietary Multi Blend 25 mg) while breaking out Fish Oil (200 mg) and Bacillus subtilis (1 Billion CFU) separately. The Hip & Joint Bites uses a single Proprietary Hip & Joint Blend (1510 mg) with no per-active split between Glucosamine, MSM, Chondroitin, and Vitamin E. Probiotic Bites reports Gut First Blend at 6 Billion CFU without per-strain split, and the marketing description references 'six strains' while the ingredient panel labels only three. Calming Bites and the 8-in-1 Cat Mousse list ingredients with no mg/CFU disclosure at all. The buyer cannot reconstruct active doses for the modal product line, and the dispersion across products itself fails the line-consistency principle.Per-active mg/CFU disclosure is missing across the modal product line. Three of five sampled flagship PDPs use proprietary-blend totals only; one (Calming Bites) discloses no doses; one (Cat 8-in-1 Mousse) is an ingredient list. The dog 8-in-1 partial break-out is the brand's best disclosure standard but is not held consistently across the line.Proprietary Hip & Joint Blend (Glucosamine HCl [Shellfish], Methylsulfonylmethane [OptiMSM], Chondroitin Sulfate [Porcine], Vitamin E [D Alpha Tocopherol]) - 1510 mgThe 'Ingredients Philosophy' page (the primary-nav science hub) carries brand-philosophy language ('Ingredients Driven By Science', 'We don't take wild guesses when it comes to ingredients') rather than mechanism content. Active ingredient names are listed without biological-role descriptions. On the home page, five branded ingredients (EpiCor Pets, AlaskOmega, Suntheanine, OptiMSM, VitaFiber) each carry a one-sentence mechanism description (e.g. 'a natural yeast fermentate (Saccharomyces cerevisiae) that promotes fresh breath and supports the immune system') but the links from these blocks route to product-collection pages, not to ingredient-mechanism deep-dives. The Mobility landing page provides three one-line ingredient roles for Glucosamine HCl, Chondroitin Sulfate, and OptiMSM. The Native Canine Probiotic page is the only place on the public surface where a meaningful ingredient-selection rationale is published, but it covers a single specialty SKU. Net: surface-level mechanism language exists for a subset of branded ingredients, deep mechanism reasoning does not.No public ingredient-by-ingredient mechanism rationale across the broader catalog. The brand's science page is philosophy copy rather than substantive biological-role explanation. Ingredient citation links (EpiCor, Suntheanine, etc.) route to collection pages instead of science deep-dives that would let the buyer verify ingredient selection logic.We use high-quality ingredients at efficaceous levels in our pawsome products. Inspired by science, each active ingredient we use is carefully selected to support your pet's health and happiness in every mouthwatering bite.The brand attaches 'clinically studied' language to specific branded ingredients (e.g. Suntheanine on Calming Bites; DE111 on Probiotic Bites; OptiMSM on Mobility) rather than to the finished product — that attribution discipline is reasonable. However, no underlying citation is surfaced: no PubMed link, no author/journal, no year, no peer-review status. The Native Canine Probiotic page is the only place on the public surface that publishes any finished-formula research framing, and it does so with honest qualifiers ('Based on early clinical data from a small-sample study conducted in 2023. Full clinical trial expected to be released H1 2026'). For the remaining 80+ supplement SKUs, evidence is ingredient-brand mentions only. No editorial-guidelines or citation-discipline page exists.No PubMed citations, no journal/author attribution, and no public bibliography for the 'clinically studied' ingredient mentions. The only finished-formula research framing (Native Canine Probiotic) covers one SKU and points to a future full RCT rather than a published study.Every chew contains Suntheanine, a clinically studied and super premium form of L-Theanine that helps promote a sense of relaxation and calmness for your pup.Zero named individuals are publicly disclosed across the entire reviewed surface. The About Us page, Ingredients Philosophy page, Native Canine Probiotic page, and Zesty Paws Professional hub all use anonymous-collective framing — 'developed with scientific and veterinary input', 'our team', 'science-led nutrition' — without naming a single veterinarian, formulator, scientific advisor, or board member. No founder is identified. The 'Vet-trusted' label on the Hip & Joint Bites PDP carries no underlying clinic-endorsement program, named DVM, or clinical-review process. The crawler's site search returned no DVM or PhD candidates. The Native Microbials partnership on Native Canine Probiotic is the only named external party, and that is a B2B genomics supplier — not a publicly identified veterinary contributor.No named DVM, PhD, formulator, or scientific advisor is reachable from any page on the public Zesty Paws site, despite the brand using 'Vet-trusted', 'Vet Strength' line branding, 'For Veterinary Professionals' nav placement, and 'developed with scientific and veterinary input' framing — exactly the language pattern the Unnamed Experts watchout is designed to catch.Products are developed with scientific and veterinary input, supported by research, observational insights, and ongoing evaluation.The footer-linked 'Product Test Results' page is the brand's primary testing artifact, and it is scoped exclusively to CBD products — a legacy line that no longer appears in the current catalog. The lot-number search field returns 'Lot number doesn't exist' on probe. For the active 80+ SKU bites / chews / mousses / powders / oils catalog, no lot-linked COA lookup exists. No third-party laboratory is named anywhere on the public surface (no Eurofins, no NSF, no Covance, no SGS). No contaminant panel scope (heavy metals), no microbial panel scope (E. coli, Salmonella), and no potency-verification panel is disclosed. The NASC Quality Seal is publicly displayed and represents a real audit program, but NASC certification is a brand-level audit standard, not a per-lot finished-product COA program in the rubric's sense.No lot-linked COA program exists for the active supplement catalog; the only on-site lookup is scoped to CBD legacy SKUs and returns no results. No third-party laboratory is named. No contaminant, microbial, or potency panel scope is disclosed publicly.CBD Product Test Results. When it comes to quality and transparency, we're not just all bark! In the field below, enter the lot number from the back of the package below to view test results for your product.Manufacturing disclosure is country-level only. The Ingredients Philosophy page states 'our line of Zesty Paws products are made in the USA with both US and imported ingredients'. The FAQ adds one SKU-level exception: 'Our products are made in the USA with globally sourced ingredients with the exception of our Omega Cat Mousse and Digestion Cat Mousse (made in Thailand).' NASC membership and GMP certification are both narratively disclosed but neither facility identity, contract-manufacturer name, city/state, nor GMP-issuing body is named. Parent-company context (H&H Group) is mentioned solely in the B Corp footnote. No sourcing-logic disclosure, no supplier list, no traceability practice description. NASC member ID is not surfaced.Facility name, city, and state are not disclosed for any product. Contract-manufacturer relationships are not named. NASC member ID, GMP audit certificate, and FDA registration number are not surfaced. Sourcing-logic and supplier-traceability content is absent.Our products are made in the USA with globally sourced ingredients with the exception of our Omega Cat Mousse and Digestion Cat Mousse (made in Thailand).Mixed pattern. The brand uses 'Helps' / 'Supports' hedge language consistently and avoids disease-treatment phrasing ('cures', 'guaranteed results', 'reverses'). Hero-level claims, however, frequently overshoot what the evidence base substantiates without inline qualifier: '8 Multifunctional Benefits in Every Chew', 'support 8 areas of dog functional wellness', 'Helps Fight Seasonal Allergies', 'Vet-trusted' (on the Hip & Joint PDP without a named clinician program). Probiotic Bites' marketing copy claims 'six strains' while the ingredient panel labels three. 'Clinically studied' is correctly attached to specific branded ingredients (Suntheanine, DE111, OptiMSM) rather than the finished product — that's reasonable claim discipline. The Native Canine Probiotic page is markedly more disciplined ('A Complete Clinical Trial is on its way and is expected to be made publicly available in the first half of 2026', 'Our goal is not to replace veterinary expertise'). No FDA disclaimer is visible in the HTML body of the home page or sampled PDPs.Above-the-fold multi-benefit claims are made without inline qualifier across the marketing surface. 'Vet-trusted' framing is used without a named-clinician program. Probiotic Bites marketing-vs-panel strain count is inconsistent. No FDA disclaimer surfaced in the HTML for the home page or sampled PDPs.8 Multifunctional Benefits in Every ChewThere is no consolidated trust hub. Evidence pages are distributed across header (Learn dropdown → About Us / Ingredients Philosophy), header (For Veterinary Professionals), and footer (Product Test Results, FAQs, Accessibility). Each is reachable in 1-2 clicks from the home page. The 'Product Test Results' page misleads structurally — its title implies brand-wide COA access but its scope is CBD-only. The Native Canine Probiotic landing (the brand's strongest evidence page) is reachable in two clicks via the Shop Dog mega-menu 'NEW: Native Canine Probiotic' link. A WCAG 2.2 / ADA accessibility statement exists with a named auditing partner (TestParty). Buyer cannot reach a named formulator, a named laboratory, a per-lot COA, or a finished-formula trial from any path because none of those artifacts exist; the accessibility score reflects the navigability of what the brand does publish, not the depth of evidence behind it.No consolidated trust hub; evidence is fragmented across header and footer. The most prominent testing artifact (Product Test Results) is CBD-only despite its name. Buyer must visit a single specialty SKU landing (Native Canine Probiotic) to reach any finished-formula research framing.Zesty Paws is devoted to ensuring that zestypaws.com remains accessible and compliant with WCAG 2.2 Level AA, ADA, and Section 508 standards.Reviewed May 23, 2026Sources: 13 sources reviewed20ZPZesty PawsZesty Paws LLCZesty Paws is a high-distribution, mass-market pet supplement brand with strong trust-badge presence (NASC, B Corp via parent H&H Group, 380,000+ reviews) but a shallow public e...Active Identity WithheldUnnamed Experts42.5/100Sparse Public Evidence
How this report was scored.
What we counted.
Every brand was scored against the same eight buyer-facing questions — doses, ingredient rationale, clinical evidence, named experts, testing & COAs, manufacturing, claim discipline, and findability. Only public, buyer-verifiable evidence was counted. Information available only via support email, retailer-only listings, or unsupported third-party language was not counted.
Brands cannot win on testing alone. A clean COA program does not substitute for ingredient rationale, named experts, or honest finished-formula evidence. Brands that lead on testing alone are flagged with the Closed Science watchout.
How La Petite Labs is scored.
La Petite Labs publishes this report and sells products in this category. Our score is shown above the rankings as a Publisher Benchmark, excluded from the ranking table and from awards. LPL's own gaps (partial COA rollout, no published finished-formula trial yet, no named per-formula scientific owner, manufacturing identity at country level only) are documented under the same evidence rules every other brand is held to.
Brand Correction Policy
Bring documented public evidence. We'll review.
Scores reflect the brand's public surface at the time of review. If a brand has materially updated label disclosure, science pages, named people, testing program, manufacturing facility, COA lookup, or claim-discipline language, it may submit those updates for correction-window review. Updates must be on public brand pages — private materials, correspondence, and retailer-only language are not counted.
Archival Snapshot Policy
Every quoted claim is captured at review time.
Every brand-rubric criterion cites at least one dated, public evidence source with a verbatim quote captured at the time of review; archived page snapshots are being attached to each source as backfill completes. Brands may update their public surface; the score reflects the capture date. Correction requests trigger fresh capture against the current public surface.

Common questions
What does "Public Evidence System" mean?
It is the flagship trust badge in this report. A brand earns it when it publishes buyer-verifiable evidence across the main pillars — label disclosure, ingredient rationale, clinical evidence, named experts — at a level a buyer can independently check before purchase. The gate is deterministic and the same rule applies to every brand.
What is a Publisher Benchmark?
La Petite Labs publishes this report and sells products in this category. We show our score separately as a Publisher Benchmark, excluded from the ranking table and competitive awards. The same rubric is used, and our own gaps are listed for readers to inspect.
How were the brands selected?
The survey targets the pet supplement brands US buyers most often search for and encounter — large mass-market and veterinary-channel brands, the major direct-to-consumer brands, and category-relevant premium brands — plus the publisher, graded separately. Selection favors market presence, not closeness to any La Petite Labs product line. Each dossier records the brand's selection rationale, and brands are added at each annual review cycle. A brand that believes it belongs in the survey can request inclusion through the correction policy.
How are watchouts decided?
Watchouts surface honest limitations in a brand's public evidence. Scores are deterministic — the same weighted formula applies to every brand. Watchouts are applied through editorial review against fixed public definitions: Closed Science is flagged when testing is strong but ingredient rationale and named experts are weak; Borrowed Evidence is flagged when a brand uses "clinically tested" language without a finished-formula study; Unnamed Experts is flagged when a brand says "vet-formulated" without naming the vet.
Can a brand request a correction?
Yes. Scores reflect the brand's public surface at the time of review. If a brand has materially updated label disclosure, science pages, named people, testing program, manufacturing facility, COA lookup, or claim-discipline language, it may submit those updates for correction-window review. Updates must be on public brand pages — private materials, correspondence, and retailer-only language are not counted.
