Open Farm Supplements Review 2026: Traceable, Not Yet Proven

Open Farm Supplements Pros and Cons

Pros

• Lot-code traceability, prominently offered: scan the code, reach deeper product information — geographic origins, safety-test results, and third-party certifications per the transparency and mission pages. This is the strongest sourcing-visibility system in our 34-brand set.
• A real quantified label on the Skin & Coat chews: EPA, DHA, omega-3, omega-6, omega-9, vitamin E, biotin, crude fat, calories, and moisture, plus a detailed ingredient-origin list.
• Disciplined claims: support language throughout the sampled supplement pages ("skin, coat, digestion, and immune support"), with the strongest assertions reserved for sourcing — which the lot system actually backs.
• Evidence surfaces are easy to reach: transparency links sit on product pages, and the dedicated transparency page is one click from anywhere. Zero watchouts fired in our scoring — rare.

Cons

• "Vet-formulated" and "vet-approved" appear in navigation and product surfaces with no named veterinarian, nutritionist, formulator, or advisor tied to the supplement line anywhere in the crawl.
• No supplement clinical citations, author/journal metadata, PubMed links, or finished-formula trial disclosure of any kind.
• The traceability system stops short of the two artifacts our rubric weighs most: no named testing laboratory and no COA — "safety test results" are promised through the lot tool but no panel is itemized publicly.
• No manufacturing facility identity or formal facility certification was surfaced — the system that names your ingredient's province doesn't name the plant.

The Traceability System Is the Real Differentiator

Give Open Farm its due: the lot-code system is the thing every other brand's "transparency" page gestures at. The transparency page tells buyers to scan the code; mission copy promises geographic origins, safety-test results, and third-party certifications behind it; and the Skin & Coat page demonstrates the philosophy in static form with origin-listed ingredients — the fish oil's source country sits right on the label section.

For a shopper whose primary worry is what went in and where it came from, no brand in our set answers faster. Our scoring gives it the strongest accessibility-and-traceability combination among the new brands, with zero watchout patterns — no borrowed evidence, no buried experts, no blend games.

What the Supplement Line Hasn't Inherited

The gaps cluster exactly where a food company extending into supplements would have them.

Nobody is named. "Vet-formulated" is in the navigation; no veterinarian is on the site. For a brand this deliberate about naming farms and fisheries, the anonymity of its formulators is a strange inversion — the ingredients have provenance; the formulas don't.

Nothing is cited. No study, journal, or PubMed link appears anywhere on the supplement surfaces. The rationale that exists (fish oil as an EPA/DHA source for skin and coat) is practical and accurate, but it is grocery-label science, not a research surface.

The audit trail stops before the lab. The lot tool promises safety-test results, but no laboratory is named publicly, no COA is downloadable, and no contaminant/microbial/potency panel is itemized. Likewise manufacturing: origin-rich on ingredients, silent on the facility.

How to verify Open Farm yourself: scan your actual lot code and see what the tool returns for your batch — then ask Open Farm for (1) the named lab and panel behind those safety results, (2) the veterinarian or nutritionist behind "vet-formulated," and (3) the facility and certifications behind the chews.

Public Transparency Score: 58.5/100

Under the 2026 Brand Transparency Rubric, Open Farm's supplement line earns a 58.5/100 Public Transparency Score — Disclosure Gaps (scored as of 2026-07-03). The score measures what a buyer can publicly verify before purchase — labels, rationale, evidence, named experts, testing access, manufacturing disclosure, claim discipline, and findability. It is not an effectiveness score, a safety score, or a best-brand ranking.

The shape is distinctive: claims (8) and accessibility (8) at leader level, testing (7) carried by the lot system, labels (7) solid — against evidence (3) and experts (4). Reading it plainly: this is a sourcing-transparency company that hasn't yet built supplement-evidence transparency. The fixes are the familiar cheap ones — name the vet, cite the studies, post one COA — on top of infrastructure most brands would envy.

Best fit: buyers who rank ingredient provenance first and want a readable omega panel for skin-and-coat support. Keep comparing if: you need named formulation accountability, any clinical citation, or an itemized test panel.

Owner Reviews and Price

The owner-review sample (45 items across 5 sources, checked 2026-07-03, medium confidence) is mild and practical: packaging notes lead (9 items), owner-reported changes and serving notes follow (6 each), with a small tolerance cluster (5 — unverified; the usual gradual-introduction advice applies).

Prices checked 2026-07-03: Skin & Coat chews (90 count) $29.99 one-time / $28.49 subscription; Probiotic chews (90 count) $34.99 / $33.24. Mid-market pricing with a notably thin subscription discount — price it as a one-time purchase.

Where La Petite Labs Fits

The overlap is the skin-and-coat lane: Open Farm's flagship supplement and Pet Gala are both daily skin-barrier systems, so this is a legitimate comparison — while the probiotic chews and Open Farm's food business sit outside anything La Petite Labs sells.

On this review's dimensions: Open Farm wins sourcing visibility outright — Pet Gala's ingredients don't carry per-ingredient origin listings, and La Petite Labs discloses manufacturing at country level (a gap we publish about ourselves). Pet Gala's advantages are the science layer Open Farm lacks: 13 actives disclosed at full mg (against a guaranteed-analysis panel that quantifies the omegas but not every active), per-batch heavy-metal, microbial, and potency testing by named labs (NSF and Eurofins) with a public COA lookup, and named DVM contributors behind the formulation frameworks. Neither brand has a finished-formula trial. Provenance versus proof — match the choice to which question keeps you up at night.

Final Verdict: Should You Try Open Farm Supplements?

Buy with reasonable confidence if ingredient provenance is your deciding factor — no brand in our set makes sourcing more checkable, the omega panel is real, and the claims won't oversell you. Scan your lot code and actually read what comes back. Verify first if "vet-formulated" or safety testing is what's persuading you: ask for the name and the panel, because neither is public yet. Pause for the standard reasons — skin issues that persist deserve a veterinary workup before supplementation, and a complete diet may already cover what a chew adds.

FAQ

Is Open Farm legit?

Yes — a well-established ethically-positioned pet food company whose supplement line inherits its signature lot-code traceability system. The supplement-specific evidence layer is the young part.

What does Open Farm's lot-code traceability actually show?

Per the transparency and mission pages: geographic ingredient origins, safety-test results, and third-party certifications for your specific lot. Scan the code on your bag to see your batch's view — and note that no public page itemizes the test panel or names the lab.

Are Open Farm supplements vet formulated?

That language appears in navigation, but no named veterinarian, nutritionist, or formulator is tied to the supplement line anywhere we could find. Ask for the name.

What is in the Skin & Coat chews?

A quantified guaranteed analysis — EPA, DHA, omega-3/6/9, vitamin E, biotin, crude fat, calories, moisture — plus an ingredient list with origins by country, state, or province. One of the more readable skin-and-coat labels in our set.

Does Open Farm publish COAs or name a testing lab?

Not publicly. Safety-test results are promised through the lot tool, but no laboratory is named and no COA or itemized panel is posted. Request the documents for your lot.

Do Open Farm supplements have clinical studies?

No supplement clinical citations or finished-formula trial disclosure was found on the pages reviewed.

Where are Open Farm supplements made?

Not disclosed at facility level — a notable inversion for a brand that names its ingredients' provinces. Ingredient origins are the disclosed layer; the manufacturing plant is not.

How much do Open Farm supplements cost?

Checked 2026-07-03: Skin & Coat chews (90) $29.99, Probiotic chews (90) $34.99, with subscription discounts under 5%. Compute per-day cost from your dog's serving size.

How do Open Farm supplements compare with Pet Gala?

In the skin-and-coat lane only. Open Farm offers unmatched ingredient provenance; Pet Gala offers per-active mg disclosure across 13 actives, per-batch testing by named labs with a public COA lookup, and named DVM contributors. Neither has a finished-formula trial. Provenance versus proof.

What should I verify before buying Open Farm supplements?

Your lot code's actual traceability output, the named lab and panel behind the safety results, the veterinarian behind "vet-formulated," and — for skin issues — whether a veterinary workup should come first.
