Best Taurine Supplements for Cats

Here's a practical look at some of the brands and product types available. These are real options you'll find in pet stores or online — described honestly, without inflated claims.

1. NOW Foods Taurine Powder

Best for: Owners who want a simple, no-frills option

NOW Foods is a well-established human supplement brand that also sells taurine powder sometimes used by pet owners for cats. It's pure taurine with no added ingredients, which makes dosing straightforward.

• Affordable and widely available
• No flavoring, so acceptance depends on the cat
• Works best mixed into wet or raw food

2. Vetri-Science Cardio-Strength

Best for: Cats with heart health concerns

Vetri-Science is a veterinary-grade supplement brand with a solid reputation in the pet health space. Their Cardio-Strength formula includes taurine alongside other heart-supporting nutrients like coenzyme Q10 and L-carnitine.

• Formulated specifically for cardiovascular support
• Often recommended alongside veterinary treatment
• Comes in a chewable form many cats tolerate well

3. Rx Vitamins for Pets Amino-B Plex

Best for: Cats on homemade or restricted diets

This liquid supplement combines taurine with B vitamins and other amino acids. It's designed for cats who may be missing multiple nutrients, not just taurine.

• Liquid format is easy to add to food
• Broad spectrum nutritional support
• Typically available through vets or veterinary distributors

4. Thomas Labs Vet-Basics Taurine Powder

Best for: Cat breeders or multi-cat households

Thomas Labs produces a range of veterinary-grade nutritional products. Their taurine powder is straightforward and designed for animals, which makes dosing more precise than adapting human supplements.

• Pure taurine powder, animal use formulation
• Suitable for adding to food in measured amounts
• Often sold in larger quantities, better value for multiple cats

5. Animal Essentials Plant Enzymes & Probiotics (with Taurine)

Best for: Cats with digestive issues alongside nutritional gaps

This product combines digestive enzymes, probiotics, and taurine in one formula. If your cat has trouble absorbing nutrients, supporting digestion at the same time makes sense.

• Addresses multiple nutritional concerns at once
• Plant-based enzymes with animal-derived taurine
• Powder format mixes into wet food easily

6. Hemopet Nu-Cat Senior

Best for: Older cats needing broader nutritional support

• Good option if your older cat needs general nutritional support
• Available in chewable tablet form

7. Raw Paws Pet Freeze-Dried Heart (Whole Food Taurine Source)

Best for: Owners who prefer whole-food nutrition over isolated supplements

Animal hearts — especially beef heart and chicken heart — are among the highest natural sources of taurine. Freeze-dried heart treats or toppers are a food-first way to add taurine without using isolated supplements.

• Natural, single-ingredient option
• Taurine content varies by product and is not always quantified
• Great as a food topper for cats on homemade diets

8. Dr. Harvey's Veg-to-Bowl Fine Ground (with Taurine Added)

Best for: Owners making homemade cat meals

Dr. Harvey's makes a base mix for homemade cat diets that includes taurine among other essential nutrients. If you're cooking for your cat, a base mix like this helps cover nutritional gaps without buying a dozen separate supplements.

• Designed specifically for homemade raw or cooked cat food
• Includes taurine alongside other required nutrients
• Simplifies the process of home feeding

9. Jazzy Fuzzy 18-in-1 Multivitamin

Best for Homemade Cat Food Diets

If you prepare raw or cooked meals for your cat at home, maintaining complete nutrition can be challenging. Taurine is an essential amino acid cats must get from food, and homemade diets may lack consistent levels without proper supplementation. Our multivitamin formula helps support nutritional balance with taurine, vitamins, and essential nutrients designed for daily wellness support.

• Helps support homemade raw or cooked cat diets
• Includes taurine for heart, eye, and overall wellness support
• Provides daily multivitamin support for cats of all life stages
