As your cat ages, the right supplements can help support good health into their senior years.
The best senior cat supplements are easy to give to your cat, contain research-backed ingredients, and come from reputable brands that do the legwork to ensure high-quality products that actually work.
Beyond these considerations, choosing the best supplements for older cats starts with understanding your kitty’s individual health concerns, from dehydration to joint pain, and selecting a supplement formulated to support these specific needs.
To make the selection process easier, our panel of Chewy veterinarians recommended their top-rated supplements designed to target health concerns common in older cats. Just make sure to consult your own vet, too, before adding a new supplement to your cat's diet.
What To Consider When Buying Senior Cat Supplements
When buying senior cat supplements, consider the brand’s reputation, the evidence behind its ingredients, the supplement format, and your cat’s individual health needs. Your veterinarian can help you choose a safe, appropriate option for your senior cat.
Brand Reputation
Look for brands that are serious about investing in research and quality testing. It can be helpful to look for the National Animal Supplement Council (NASC) Quality Seal, which indicates that a company has met rigorous standards for quality control. That said, not every reputable supplement manufacturer participates in the program, so it's also worth looking into a brand's specific practices when it comes to research and quality testing.
Evidence-Based Ingredients
Make sure a supplement's active ingredients have research supporting their intended use. For example, omega fatty acids have been shown to have cognitive benefits in aging cats, while probiotics support feline gastrointestinal health.
Supplement Format
Senior cat supplements come as liquids, sprinkle capsules, chews, and powders. The best format is usually the one that your cat will reliably take. Brands formulate supplements to be tasty and enticing to senior cats, and many can be mixed into their food.
Your Senior Cat’s Individual Needs
Your kitty’s overall health, as well as their diet, play a role in what supplements they may benefit from. Be sure to talk to your vet to determine which options are best for your pet’s unique needs.

Senior Cat Supplements FAQs
Do senior cats need supplements?
Senior cats don't necessarily need supplements so long as they are eating a complete, balanced diet and are able to maintain a healthy weight. However, your vet might recommend supplements to address your cat’s individual health challenges as they get older, including options that support healthy teeth, cognitive function, and mobility.
What supplements are recommended for older cats?
No one supplement is right for every older cat. The best supplements will vary depending on your kitty’s individual needs. That said, veterinarians recommend supplements from reputable brands, like Nutramax, Purina Pro Plan, and VetriScience, that include high-quality, research-backed ingredients. Ideally, the recommended supplements are also ones your cat is willing to take.
Do senior cats need multivitamins?
Most senior cats do not need multivitamins if they are eating a complete and balanced diet, as high-quality cat food is designed to meet their nutritional needs. Your vet might suggest a more specialized supplement to support your older kitty’s specific health needs. However, some multivitamins may come in handy; for example, our veterinary panel recommends a VetriScience Active Health multivitamin for brain support in senior cats.
