Polyphenols for cats are a family of plant compounds that includes resveratrol, quercetin and many compounds carried in fruit or fiber ingredients. Researchers study them for their effects on oxidation and cellular processes. The ingredient’s identity and the way it is delivered help explain what it can do. 3 4

For an owner choosing daily nutrition, that creates a useful question: how does a named plant compound fit with the rest of the formula? Hollywood Elixir combines resveratrol and quercetin with an NAD+ precursor, mitochondrial cofactors, antioxidant nutrients and other ingredients in a 17-active system. Its purpose is broader cellular nutrition for adult and senior cats. 7

Start with what the different polyphenols are, look at the feline findings, then consider the complete formula you would be adding to your cat’s food.

  • Polyphenols include different compounds and preparations; a fruit-powder weight is not an assayed polyphenol amount.
  • Direct feline research includes food-matrix, metabolic-marker and disease-specific combination studies.
  • A study’s measured result matters: blood or fecal changes do not automatically establish an everyday benefit.
  • Hollywood Elixir declares resveratrol extract, quercetin dihydrate and blueberry fruit powder within its full 17-active formula.
  • NR, CoQ10, B vitamins, glutathione and other ingredients extend the design across different cellular-nutrition roles.
  • Review the full composition and product-specific portion when choosing a daily formula.

Polyphenols are a family with different members

“Polyphenol” describes a broad chemical family. Resveratrol is one member; quercetin belongs to a subgroup called flavonoids. A berry ingredient can contain a mixture of plant compounds, while a standardized extract names a more specific preparation. These labels answer different questions about what is in the serving. 3 4

For example, 50 mg of blueberry fruit powder describes the powder’s weight. It does not tell you that the serving contains 50 mg of polyphenols. A named resveratrol extract with a stated standardization gives different composition information. Both can belong in a formula, but they should be read on their own terms. 7

That distinction is the starting point for comparing a food, an individual ingredient and a prepared supplement. It is also why a finding about one polyphenol preparation cannot automatically describe every product in the category.

Why plant compounds are studied in a carnivore

The nutritional starting point is that cats are obligate carnivores. They need a diet that supplies their particular balance of protein, amino acids, fats, vitamins and minerals. Complete cat food remains the foundation, including nutrients such as taurine that cats must obtain from their diet. 2

A plant compound can still interact with a cat’s biology. The relevant question is what that interaction adds to an already appropriate diet. A polyphenol supplement should be evaluated as an addition with a defined purpose, rather than a way to compensate for an incomplete meal.

Our cat vitamins and supplements guide puts those choices in context. For a growing kitten, food formulated for growth takes priority; for an adult or senior cat, the life-stage guide helps frame changing nutritional and care needs. Hollywood Elixir is positioned for adult and senior pets. 7

Fiber changes how polyphenols meet the gut

Plant compounds can travel with food’s fibrous material, which gut microbes process into smaller substances called metabolites. A 2022 study tested this relationship in 56 healthy adult cats eating complete foods with different amounts of a fiber bundle for 31 days. 1

The bundle combined pecan shells, flaxseed, beet pulp, citrus pulp and cranberry pomace. Fecal polyphenol metabolites increased, while the highest inclusion level lowered ammonia and certain branched-chain fatty acids. Stool firmness did not improve.

The study shows how food composition can change microbial metabolism. It does not establish symptom relief from an isolated extract.

Resveratrol has been studied in feline metabolism

A 2025 experiment tested trans-resveratrol in 12 healthy cats, divided into three groups, and a separate group of four overweight or obese cats. The four-week study measured blood markers and body condition. In the healthy cats, the low-dose group showed an increase in adiponectin, a hormone involved in metabolism. 3

The overweight or obese cats showed changes in several lipid and inflammatory markers, but they had no matched untreated group. Body weight and body condition did not change. This is early metabolic research, not evidence that resveratrol is a weight-loss treatment.

For a cat carrying excess weight, the practical priority is an appropriate feeding and activity plan. For the ingredient’s background and narrower research questions, see resveratrol for cats.

Quercetin can affect enzymes as well as oxidation

Polyphenols are often introduced as antioxidants, but researchers also investigate their effects on enzymes. One example is CD38, an enzyme that consumes NAD+, a molecule used in cellular metabolism. 4

In laboratory experiments, quercetin inhibited CD38 and increased NAD levels in the tested cells. Those experiments used purified enzyme and cell systems. The same paper’s metabolic experiments in living mice tested apigenin, a different flavonoid.

This work gives a specific reason for scientific interest in quercetin within cellular nutrition. It does not demonstrate that an oral quercetin serving preserves NAD in a cat. Our quercetin guide follows the individual ingredient; here, its place is alongside the other compounds and nutrients in a complete formula.

In a 56-cat feeding study, a fiber-and-polyphenol blend changed the metabolites found in feces, showing that food composition can influence what gut microbes produce.

A feline combination trial addressed a specific illness

One randomized, blinded study followed hyperthyroid cats receiving methimazole for 180 days. Thirty cats completed treatment: 14 received a placebo alongside the medicine, and 16 received a paste containing curcumin, quercetin, resveratrol and vitamin E. 5

The supplemented group had more favorable oxidative-stress measurements. Medication-related side effects were reported in two of 16 supplemented cats and five of 14 controls. The study investigated a particular combination during treatment of a particular disease; it did not isolate quercetin or resveratrol’s contribution.

For a cat already receiving thyroid treatment, this is a question to discuss with the treating veterinarian. It is not a reason to replace medication or assume that Hollywood Elixir duplicates the studied paste.

Blood markers and everyday changes answer different questions

The cat studies give researchers useful measurements: what appears in feces, how blood markers change, or what happens during a defined treatment. Owners usually want to know something more immediate—whether their cat will eat better, move more or have firmer stools.

Those outcomes need their own measurements. The studies above do not establish a general timetable for a visible response to a polyphenol supplement. A four-week blood test is not a promise of a four-week improvement in appetite or activity. 1 3

If an older cat has become less active, start with the change itself. The low-energy guide helps organize that concern. A daily nutritional addition can have a place in the routine, while a new symptom still deserves an explanation.

Tea, fruit powder and extracts deserve different decisions

Tea contains catechins, another group of plant compounds, but tea products can also contain caffeine. Caffeine can be toxic to cats; tea bags and concentrated supplements are among the exposures that can cause serious problems. Human tea or an energy supplement is therefore a poor starting point for feline nutrition. 6

A “decaffeinated” claim answers one composition question. It does not establish the suitability of every other ingredient or the right portion for a cat. Look for the complete preparation and intended species, rather than treating one removed ingredient as an overall safety guarantee.

Fruit powder, meanwhile, names a food ingredient with its own composition. Standardized resveratrol and quercetin preparations provide more specific ingredient declarations. Hollywood Elixir contains those two named preparations and blueberry fruit powder; its current active panel does not list tea extract. 7

Read the ingredient form and the serving together

A useful label tells you what the ingredient is, how much of that preparation is declared, and the serving used for that declaration. Read the full formula too: a product described through one featured ingredient may contain many others.

For Hollywood Elixir, the amounts are declared per full 2.5 g sachet. A cat’s daily portion follows the product’s weight directions, so “per sachet” and “per day for my cat” may differ. The printed amount also belongs to the named preparation, including any stated concentration. 7 13

The complete ingredient panel lets you inspect all 17 active rows. That is the clearest place to compare the formula with another supplement already in your cat’s routine.

The polyphenol ingredients in Hollywood Elixir

Hollywood Elixir declares 15 mg of resveratrol extract, standardized to 98% from Polygonum cuspidatum, and 25 mg of quercetin dihydrate 95% per full sachet. It also contains 50 mg of blueberry fruit powder. These are the declared ingredient amounts; the blueberry line does not provide a measured polyphenol amount. 7

The two named preparations make the polyphenol part of the design specific. Blueberry adds a whole-fruit ingredient to that composition. Together, they sit within a larger formula intended for cellular aging and vitality nutrition.

That larger context is the reason to consider Hollywood Elixir: it brings the plant ingredients into a daily system that also addresses energy metabolism and antioxidant nutrition.

Food provides fuel. NAD participates in processing that fuel, and CoQ carries electrons through mitochondria. These distinct jobs explain Hollywood Elixir’s broader approach to cellular nutrition.

DVM Voice: Clinical Vignette of a Common Pattern in Senior Cat Aging

Case provided by JoAnna Pendergrass, DVM

Sasha, a 12-year-old cat, was brought in after her owner noticed increased thirst and urination, lethargy, vomiting, and a generally unkempt appearance. Examination showed weight loss, elevated blood pressure, and reduced vitality.

Diagnostic testing revealed elevated kidney markers, poorly concentrated urine, and protein loss in the urine — findings consistent with chronic kidney disease, one of the most common chronic conditions in senior cats.

Her care required a kidney-focused diet, blood pressure management, targeted supplementation, medication support, and regular monitoring — a necessary plan, but one started after clinical signs were already visible.

Clinical takeaway: Sasha’s case reflects why senior-cat wellness should begin before obvious decline. Earlier monitoring, body-condition tracking, hydration awareness, antioxidant support, and daily cellular resilience may help support quality of life as cats age.

Single-case vignette. Not generalizable. Veterinary diagnosis and monitoring are essential for increased thirst, urination, vomiting, lethargy, weight loss, or suspected kidney disease.

From the meal to cellular energy

Food supplies the protein, fat and carbohydrate that the body can use for energy. Cells process that fuel through a series of reactions; vitamins and other cofactors help the reactions work. A supplement can be designed around those supporting roles without being a substantial source of calories. 12

NAD+ and its reduced form, NADH, participate in the transfer of electrons during metabolism. Nicotinamide riboside, or NR, is a precursor used to make NAD. CoQ has another job: it carries electrons within the mitochondrial machinery that helps produce usable cellular energy. 8 9

Hollywood Elixir places NR tartrate beside CoQ10 and B-vitamin ingredients. The connection is concrete: precursor supply, electron transfer and enzyme cofactors are different parts of cellular nutrition. That is the foundation of its NAD+ system. 7

See how cells make, use and recycle NAD+ in our NADome and NADomics guide.

Antioxidant nutrition has several connected roles

Cells also maintain systems that manage oxidation. Glutathione is one of those systems. When oxidized glutathione is converted back to its reduced form, the reaction uses NADPH; the enzyme involved relies on FAD, a cofactor made from riboflavin, or vitamin B2. 10 11

Vitamin C and vitamin E have antioxidant roles too. These different molecules help explain why an antioxidant-oriented formula can include vitamins and glutathione alongside plant compounds. 12

Hollywood Elixir includes reduced glutathione, B2, C and E within that wider design. This is the biological rationale for combining their nutritional roles; it is not a measured claim that the finished formula increases glutathione recycling in cats. The antioxidants guide explores the broader category. 7

Hollywood Elixir’s complete 17-active formula

The full formula brings several kinds of cellular nutrition into one prepared serving. The current declaration below is per full 2.5 g sachet, with ingredient forms and amounts kept together. 7

NAD+ and energy-related ingredients

  • Nicotinamide Riboside Tartrate — 60 mg
  • Coenzyme Q10 98% (Ubidecarenone) — 40 mg
  • Vitamin B3 (as Niacin) — 2 mg
  • Vitamin B2 (as Riboflavin) USP — 0.5 mg
  • Vitamin B6 (as Pyridoxal 5-Phosphate) — 1 mg
  • Vitamin B12 (as Methylcobalamin Trit 1% on DCP) — 0.25 mg

Antioxidant nutrients and plant ingredients

  • L-Glutathione Reduced — 50 mg
  • Vitamin C (as Ascorbic Acid) — 10 mg
  • Vitamin E D-alpha Tocopheryl Acid Succinate 1210 — 15 IU
  • Astaxanthin 2% (natural) — 2 mg
  • Resveratrol Extract (Std. 98% from Polygonum Cuspidatum) — 15 mg
  • Quercetin Dihydrate 95% — 25 mg
  • Blueberry Fruit Powder — 50 mg

Ingredients selected for immune support, plus food ingredients

  • Beta Glucan (Beta-1,3/1,6-D-Glucan Powder), from Saccharomyces cerevisiae — 50 mg
  • Reishi Mushroom Powder P.E. (Std. 35% Polysaccharides) — 25 mg
  • Organic Spirulina Powder — 50 mg
  • Whey Protein Isolate 90% (WPI) — 250 mg

The additional “Contains” list names chicken flavor, chicken liver powder, yeast extract, glycine and hydroxypropyl beta-cyclodextrin. Review it alongside the active panel, especially when your cat has a known food sensitivity.

Why the whole formula matters to the purchase

The ingredients do not all perform the same job. NR is included as an NAD precursor; CoQ10 and B vitamins extend the energy-metabolism design. Glutathione, antioxidant vitamins and named plant compounds give the formula another set of nutritional roles. The yeast, mushroom and food ingredients complete its broader healthy-aging composition. 7

The yeast beta-glucan and standardized reishi preparation are selected to support immune health. Spirulina and blueberry supply distinct food ingredients, and whey supplies a protein ingredient. The cat’s complete food remains the main source of dietary protein.

For an owner, the value is a purposeful combination in one daily product. You can understand the reason for the whole formula and inspect its complete declaration, instead of having to assemble a routine around separate human capsules. The cat longevity supplement guide places this choice within wider senior nutrition.

Match the daily portion to your cat

Hollywood Elixir’s current daily directions specify half a sachet for pets under 7 lb, one sachet for 7–30 lb, and two sachets over 30 lb. For a cat in the 7–30 lb band, the full-sachet declaration is also the daily amount. These are this product’s instructions, not a dosing rule for other polyphenol products. 13

Mix the applicable portion into food and serve it immediately. Check other supplements for overlapping ingredients before adding another product. If your cat has a prescribed diet or treatment plan, review the complete formula and intended portion with the veterinarian responsible for that plan.

Keep the familiar complete meal central. The formula’s role is to add its connected cellular-nutrition ingredients to that meal.

Keep new symptoms separate from supplement shopping

Loss of appetite can have many causes, including illness, and deserves prompt attention in a cat. If food intake falls after a new addition, stop the addition and contact your veterinarian rather than waiting for a supposed adjustment period. 14

Existing disease also changes the decision. Owners managing diabetes, liver disease or chronic digestive problems should bring the full supplement label to the treating veterinarian. The guides to diabetes treatment, liver health and common veterinary concerns help organize those discussions; they are separate from the nutritional purpose of polyphenols.

Water intake deserves its own attention too. If you are worried about drinking or fluid loss, use the dehydration guide and seek advice about the change. A plant-compound formula is not fluid replacement.

Look for a full declaration and useful quality records

A good purchasing decision begins with a formula you can examine: ingredient names, forms, amounts, serving instructions and the additional ingredients that affect suitability. Then look for documentation tied to the product and batch.

La Petite Labs provides a public COA lookup. Its product information states that batches undergo third-party checks for heavy metals and microbial contamination. Those records concern product quality; they do not establish that a cat will experience a particular health outcome. 15

When reviewing a report, match the lot and the tests to your question. A contaminant result and a measurement of an ingredient’s concentration tell you different things.

Choose more complete cellular nutrition

Choose Hollywood Elixir’s 17-active NAD+ system when you want named polyphenols within a broader daily formula for your adult or senior cat. Resveratrol and quercetin sit alongside NR, CoQ10, B-vitamin cofactors, glutathione, antioxidant vitamins and the formula’s wider healthy-aging ingredients. 7

The reason to choose it is the connected nutritional design: several distinct cellular roles brought into one prepared formula for food. You can see what is included and select the portion that fits your cat.

Explore Hollywood Elixir, then choose your daily plan.

Choose Hollywood Elixir for named polyphenols within a 17-active system that also brings together an NAD+ precursor, mitochondrial cofactors and antioxidant nutrients.

FAQ

What are polyphenols for cats, in simple everyday terms?

They are a family of plant compounds found in ingredients such as fruit, plant extracts and some fiber sources. Resveratrol and quercetin are named examples. A complete cat diet supplies essential nutrition; a polyphenol formula is an addition with its own composition and purpose.

What side effects can polyphenols supplements for cats cause?

There is no single side-effect profile for this broad category. The extract, other ingredients, portion and cat’s health all matter. Stop a new addition and contact your veterinarian if appetite falls or vomiting develops. Caffeine-containing tea products create a separate toxicity concern. 6 14

Can polyphenols for cats interact with prescription medications?

A medication plan needs a review of the specific supplement. Plant-derived ingredients are biologically active, and a whole formula may contain several relevant compounds. Give the treating veterinarian the complete label and intended portion; do not use the hyperthyroid combination study as permission to add a different product to methimazole.

How soon might I notice changes after starting polyphenols for cats?

No general timeline for visible improvement has been established. The feline studies discussed here measured defined laboratory or treatment outcomes, which are different from an owner noticing more activity or better appetite. A new symptom should be assessed on its own merits.

Are polyphenols for cats different from polyphenols for dogs?

A named chemical can be the same, but the animal’s nutritional needs and product instructions differ. Use a formula intended for cats and its current serving directions. A dog study or a dog’s portion does not establish the appropriate choice for your cat.

Can polyphenols for cats support stool quality and regularity?

The fiber-bound polyphenol study found metabolic changes without better stool firmness. It does not establish constipation or diarrhea relief. Persistent stool problems need assessment. 1

When should I call my veterinarian before using polyphenols for cats?

Contact the treating veterinarian first when your cat takes medicine, follows a prescribed diet or has ongoing illness. The full ingredient list and your intended purpose make that discussion useful. Hollywood Elixir is positioned for adults and seniors; young, pregnant or nursing pets need a separate suitability decision.

What does research in cats actually suggest about polyphenols?

Different preparations have produced changes in gut metabolites, metabolic markers and oxidative-stress measures in specific studies. These findings justify further interest, while the actual preparation and population limit what they tell us about another formula. They do not establish that Hollywood Elixir extends feline lifespan.
