Let’s see, you pop biotin supplements to grow out your hair, chew collagen gummies to stave off wrinkles, and stir adaptogens into your coffee for mental clarity. Isn’t your cat entitled to whatever superfood du jour promises them eternal youth, too?

Before you slip a supplement into your cat’s kibble, confirm with your vet that your cat doesn’t have any health concerns to consider first or that there’s potential for a medication interaction. “Humans take vitamin supplements because most of us have terrible diets,” says Dr. Angela Rollins, DVM, PhD, DACVM. “Even though it might be beneficial for us, most commercial cat foods are actually high-nutrient diets that don’t need extra vitamins or supplements. Calcium and phosphorous should also be in correct proportion to each other so giving your cat a vitamin supplement with extra phosphorous could throw that off balance. You may end up overdoing certain nutrients and introduce the potential for toxicity.”

That said, Rollins adds, “most pet vitamins tend not to be very potent because manufacturers know they are being given in addition to an already complete and balanced diet.” Supplements show the most promise (and proven results) when cats have health conditions or vitamin deficiencies — from omega-3 fatty acids’ heart-health benefits to antioxidants’ ability to fight chronic inflammation. You should still choose wisely: read labels to ensure quality and look for brands that ideally have clinical studies backing their products. Below, seven cat vitamins and supplements for your consideration.

Btw, our editors (and their pets) picked out these products. They’re always in stock at the time we publish, but there’s a chance they’ll sell out. If you do buy through our links, we may earn a commission. (We’ve got a lot of toys to buy over here, you know?)

select pet antioxidants

You’ve probably heard of the benefits of antioxidants in skincare (protection of free radicals and such). Antioxidant supplements — especially those containing vitamins C, E, and beta-carotene — can fight the chronic inflammation associated with allergic dermatitis and arthritis, and have also been proven to be beneficial for cats in renal failure. There are numerous individual antioxidant supplements but you’ll get more bang for your buck with a combo like Vetoquinol Select Antioxodant Tablets.
