Niacin is vitamin B3, a nutrient your cat needs to help turn food into usable energy. Niacinamide—also called nicotinamide—is one form of that vitamin. It can be included in formulated cat food to supply the B3 a cat needs. 1 2

The amount and the product matter. A complete cat food supplies niacin as part of a balanced diet; a swallowed human tablet or a lick of face cream is a different exposure. For a suspected excess or reaction, contact your veterinarian with the full product label and the amount involved. 7 3 12

Niacinamide and nicotinamide are the same B3 form; nicotinic acid is another. Both belong under niacin, while NR is a separate NAD precursor. The unfamiliar name on a food label tells you the ingredient’s identity, not the total niacin in the meal. 1 4

One FEDIAF adult-food recommendation is 10.50 mg niacin per 1,000 kcal, on its lower energy-intake basis. A hypothetical 200 kcal of food at that concentration supplies 2.10 mg niacin. That is food-provided intake. Deficiency is uncommon with adequate complete food; historical deficient diets caused poor growth, diarrhea and weight loss in kittens. 6 9

Hollywood Elixir lists 2 mg niacin and 60 mg NR per full 2.5 g sachet. The ingredient guide identifies NR tartrate and calls B3 simply niacin, without specifying nicotinic acid or nicotinamide. Cat directions offer half- or full-sachet daily portions, mixed into usual food and served immediately. 15 16

Niacinamide on a cat-food label

Niacin, vitamin B3, nicotinic acid, nicotinamide: a short ingredient list can contain several names for closely related nutrition. Niacin is the umbrella term. Nicotinic acid is one form; nicotinamide is another, and niacinamide is simply another name for nicotinamide. 1 2

Niacinamide can therefore appear in food to supply a vitamin cats need. EFSA’s assessment of a specified nicotinamide feed additive found it safe for animal nutrition under its authorized use. That supports its place in formulated food; it does not turn an arbitrary amount from a human bottle into a cat serving. 2 3

For the ordinary food decision, look for a complete diet suited to your cat’s life stage. Its niacin belongs within that diet’s overall nutrient balance. 7

How B3 helps turn a meal into usable energy

Food brings in fats, proteins and other nutrients. Cells break those nutrients down through chemical reactions, transferring some of their energy to ATP—an energy-carrying molecule that powers much of the cell’s work. Niacin helps supply NAD, one of the coenzymes that makes those reactions possible. A coenzyme is a small molecule that works with an enzyme. 1 4

NAD+ accepts electrons and becomes NADH. NADH can pass them onward, returning to NAD+. These changes are part of how cells obtain usable energy from a meal. The vitamin helps the machinery work; it is not providing calories or acting as a stimulant. The NAD+ guide for cats follows the coenzyme’s wider roles in energy and cellular maintenance. 1 4

Why cats need niacin from food

Tryptophan is an amino acid in protein, and many animals can use it to make niacin. Cats make too little this way to meet their needs. They have the pathway, but a competing reaction diverts much of the material away from niacin production. 5

In a 1965 experiment comparing cat and rat liver enzymes, the cat preparations made much less of a niacin-related intermediate and had far more activity in the competing breakdown route. Adding the competing enzyme to rat-liver preparations reduced their production too. That helped explain why the feline route yields so little. 5

A protein-rich meal still needs to supply niacin itself. Complete cat foods are formulated around that dietary dependence, rather than relying on the cat to make enough B3 from protein. 9 7

How much niacin belongs in a cat’s food?

Food guidelines often express nutrients per 1,000 kilocalories, usually written kcal. FEDIAF gives minimum recommended adult-cat food concentrations of 10.50 or 8.00 mg niacin per 1,000 kcal, depending on assumed energy intake. The higher concentration is for cats eating fewer calories: their smaller food intake still needs to bring in enough of the vitamin. 6

For a hypothetical cat eating 200 kcal of food made at 10.50 mg per 1,000 kcal, the calculation is 10.50 × 200 ÷ 1,000 = 2.10 mg niacin from food. The calories and niacin concentration of the food actually eaten determine the real intake. 6

You would not add another 2.10 mg merely because the example gives that number. The recommendation describes the food’s nutrition, not a universal supplement dose or a safe upper limit. 6

Where the niacin in a meal comes from

Meat, poultry and fish supply naturally occurring niacin, much of it already incorporated into NAD and NADP. Formulated food can also include added niacin to reach its nutritional specification. Both contribute to what the cat eats; the added vitamin is not the whole niacin content of the meal. 1 7

An ingredient list cannot give you the total milligrams of B3. A complete food’s nutritional adequacy is more useful than judging the diet by whether niacin appears as a separate ingredient. If you prepare food at home, a professionally formulated recipe needs to balance all the nutrients together. Adding a vitamin-rich meat or a sprinkle of fortified yeast cannot, on its own, establish that balance. 1 7

Cats can use tryptophan to make some niacin, but too little to meet their needs. Their food must supply the vitamin.

Does cooking destroy the niacin?

Heating a food does not affect every vitamin in the same way. In a 2023 cat-food experiment, researchers measured B vitamins before and after retorting—the heat treatment used to process food in sealed containers. Niacin did not change significantly through the process they tested. 8

This was an analysis of the food, not a trial feeding cats. Its practical lesson is that canning alone is not a reason to assume the niacin has disappeared. The finished formulation and processing conditions determine the food’s nutrient content. 8

What niacin deficiency looks like in cats

Merck’s veterinary nutrition review describes poor growth, diarrhea and weight loss in kittens fed niacin-deficient diets. Those kittens did not develop the skin or mouth lesions familiar from descriptions of deficiency in other species. 9

Deficiency is uncommon when cats eat adequate complete food. Poor appetite or weight loss can have many causes, so neither is a home test for low B3. If your cat stops eating, seek veterinary attention promptly; simply adding niacin leaves the cause of the appetite change unresolved. 9 10

What a cat diet study found about B3 use

A 2023 study looked at cats with chronic enteropathy, meaning ongoing intestinal disease. They were fed a complete diet based on hydrolysed soya protein for six weeks. Researchers examined molecules in urine and other samples to see how the cats’ metabolism changed with the food. 11

In both study-centre groups, urine contained more N-methylnicotinamide after the diet. This is a breakdown product related to niacin metabolism. The researchers discussed several possible reasons: the food’s niacin supply, its digestibility, or better absorption as the intestine recovered. 11

What is in a meal and what a cat can absorb both matter to nutrition. Here the intervention was the whole food, and the measurement was a urine metabolite—not a test showing that a niacin supplement treats intestinal disease or raises blood NAD. 11

B3 for kittens, older cats and skin concerns

A kitten needs complete food formulated for growth; an adult needs food appropriate to its own life stage and condition. Growing older does not, by itself, show that a cat lacks niacin. Changes in eating, weight or skin deserve attention to the whole diet and the cat’s health. 7 9 10

Niacinamide also appears in veterinary skin-treatment discussions, but that is a different use. The VCA guidance describes it alongside other medicines for inflammatory skin conditions in dogs. It does not provide evidence that an extra B3 powder restores a cat’s coat. 12

Niacin, NR and a B-complex are different labels

NR, or nicotinamide riboside, is another starting material for NAD. Nicotinamide and NR can both reach the intermediate NMN through different enzyme routes; nicotinic acid reaches NAD through a separate branch. Their related names do not make their supplement amounts interchangeable. The NAD precursor comparison for cats explains those options in more detail. 4 6

A B-complex is a mixture rather than another name for B3. Its full ingredient list matters, especially when it is added to another supplement that already contains niacin. Our B-vitamin guide for cats explains the broader family and the distinction between a combination and a single vitamin. 3 7

At 10.50 mg niacin per 1,000 kcal, 200 kcal of food supplies 2.10 mg of the vitamin. The food’s concentration and the amount eaten work together.

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.

B3 also contributes to antioxidant chemistry

The vitamin’s work extends beyond obtaining energy. NAD can also become NADP, a related coenzyme used in building molecules and maintaining antioxidant function. Its reduced form, NADPH, can supply electrons for these reactions. 1 13

One example is glutathione recycling. When glutathione is oxidized, an enzyme called glutathione reductase uses NADPH to restore its reduced form. That lets the antioxidant system reuse the molecule. B3 helps supply the coenzyme behind this reaction; this is part of its normal nutritional role. 13 1

Can extra niacin cause side effects?

Water-soluble does not mean harmless at every amount. Veterinary toxicology guidance describes stomach and intestinal upset after B-vitamin ingestion, and flushing or itching with niacin in pets. These general observations do not identify a universal safe tablet fraction for a cat. 3

A human multivitamin can also contain ingredients that change the risk. If your cat has taken an excess or develops a reaction, contact your veterinarian immediately. Have the complete label, estimated amount and time of exposure ready; mention any medicines your cat receives. 3 12

If a cat licks niacinamide skincare

A face cream is a mixture, even when niacinamide is the ingredient printed most prominently on the front. After a suspected exposure, prevent further licking and contact your veterinarian with the product details and estimated amount. The complete formula matters to that assessment. 3 12

A cosmetic’s percentage or the number of hours since application cannot supply a feline safety answer on its own. Keep the container available so the actual ingredients can be checked. 3 12

Niacinamide and kidney-disease questions

For a cat with chronic kidney disease, a renal diet addresses phosphorus, energy intake and other nutrients together. Blood-phosphorus monitoring helps the veterinarian decide whether a phosphate binder is needed as well. B vitamins in the diet are only one part of that nutritional care. 14

A human niacinamide bottle should therefore not replace the prescribed food or binder on the strength of an owner’s dosing story. Take the bottle, current diet and medicine list to the treating veterinarian. If the cat will not eat its renal food, say so: maintaining food intake is part of managing the disease, not a detail to work around by adding a vitamin. 14 3

Why Hollywood Elixir includes vitamin B3

Hollywood Elixir includes B3 and NR as starting materials for NAD production. B3’s place in the formula begins with its essential nutritional job: helping supply the coenzymes cells use to obtain usable energy from food. 1 4 15 16

CoQ10 carries electrons onward after NADH has passed them into the energy-transfer machinery. Glutathione has another job: its reduced form participates in antioxidant work, and NADPH helps restore it after oxidation. Hollywood Elixir includes CoQ10 and reduced glutathione alongside B3 and NR, combining ingredients that build the coenzymes with ingredients used in the processes they support. 17 13 15

The combination comes in one powder for an adult or older cat’s usual food. The Hollywood Elixir ingredient guide describes what is included. This case for combining the ingredients comes from normal biology; the studies here have not measured the finished formula’s effects in cats. 15 16

The niacin amount in a Hollywood Elixir portion

A full 2.5 g sachet lists 2 mg niacin and 60 mg NR. The ingredient guide identifies the NR as nicotinamide riboside tartrate. Its B3 entry says “Vitamin B3 (as Niacin),” without specifying nicotinic acid or nicotinamide. 15 16

The manufacturer’s Lite portion, for under 7 lb or sensitive pets, is half a sachet daily: 1.25 g powder containing 1 mg niacin and 30 mg NR. Standard, for 7–30 lb, is one sachet daily. The product and serving options provide the actual directions. 15

The sachet’s grams describe the whole powder; the milligrams describe separate ingredients within it. Adding the NR amount to the niacin amount would not give a 62 mg niacin dose. These portions also remain separate from the food-niacin calculation above. 15 6 4

Mixing the powder into the usual meal

The directions are straightforward: choose the daily portion, mix it into the usual food, serve immediately and repeat daily. Start with a meal your cat already enjoys. If the addition makes the cat turn away, offer the familiar food without it and review the approach. Forcing a disliked mixture can worsen food aversion. 15 10

Hollywood Elixir is intended for adult and senior pets. Kittens, pregnancy and nursing require veterinary guidance, as do existing illness or medicines. Its suggested 90-day routine is a manufacturer’s routine, not a measured time to a change in a cat’s energy or coat. Appetite loss itself needs prompt veterinary attention. 15 10

Choosing B3 support for your cat

For essential B3, the complete food your cat eats usually does the job. A suspected deficiency needs a specific assessment of that diet and the cat’s health. An optional NAD-support powder is an addition to this foundation. 7 15 10

Vitamin B3 helps supply a coenzyme cells use to restore glutathione, so this antioxidant can be used again.

FAQ

Are niacin, vitamin B3 and niacinamide the same thing?

Niacin is vitamin B3. Nicotinamide and niacinamide are two names for the same B3 form; nicotinic acid is another form. The vitamin helps supply NAD, a coenzyme that participates in obtaining usable energy from food. Niacinamide can be used as a nutritional ingredient in formulated food.

Is niacinamide toxic to cats?

Niacinamide has legitimate nutritional use in animal feed. That does not make every dose or product safe: concentrated supplements can cause adverse effects, and a human tablet or cosmetic may contain other ingredients that matter. For suspected excess or a reaction, contact your veterinarian immediately with the full label and estimated amount.

How much niacin does a cat need each day?

Food recommendations depend on the food’s energy basis and how much the cat eats. One FEDIAF adult-food recommendation is 10.50 mg per 1,000 kcal on its lower energy-intake basis. A hypothetical 200 kcal at that concentration supplies 2.10 mg niacin from food. This is not an instruction to add another 2.10 mg. Supplement amounts require their own product and veterinary guidance.

Can I give my cat a human niacin or B-complex supplement?

Do not resize a human tablet into a cat dose by guesswork. Have your veterinarian assess the actual product, ingredient amounts and any other supplements or medicines. A B-complex contains a mixture; the B3 amount is only one part of the label. An adequate complete food generally does not need extra vitamin supplementation.

Do kittens, seniors or different-sized cats need different amounts?

Choose complete food appropriate to life stage rather than a niacin dose based on breed or age alone. For Hollywood Elixir, the manufacturer’s Lite portion is half a sachet daily for under 7 lb or sensitive pets; Standard is one sachet for 7–30 lb. The product is intended for adults and seniors, with veterinary guidance for kittens, pregnancy, nursing, illness or medicines.

Can niacin improve my cat’s skin or coat?

B3 is needed for normal nutrition, but a dull coat does not diagnose niacin deficiency. The feline deficiency account describes poor growth, diarrhea and weight loss in kittens, without skin or mouth lesions. Veterinary niacinamide treatment for inflammatory skin disease described by VCA concerns dogs and other medicines, not a demonstrated coat benefit from extra B3 in cats.

Can niacinamide replace a phosphorus binder for a cat with kidney disease?

Do not replace a prescribed renal diet or binder with a human niacinamide supplement without the treating veterinarian’s direction. Renal nutrition manages phosphorus and other nutrients together, with blood results helping guide binder use. Bring the exact bottle, current food and medicine list to the discussion, and mention any difficulty getting your cat to eat.

How do I give the powder, and how long before I notice a difference?

Hollywood Elixir’s instructions say to choose the daily portion, mix it into usual food, serve immediately and repeat daily. If your cat refuses the mixture, offer the usual food without the addition. The manufacturer’s 90-day routine is not a measured feline response time. Seek veterinary advice for appetite loss rather than waiting for a supplement to change it.
