Recent research shows how common osteoarthritis is in cats; studies indicate it’s far more widespread than we previously thought. A 2026 article from North Carolina State University reported ongoing research into disease markers and therapeutic targets for feline osteoarthritis (North Carolina State University, 2026). The FDA also emphasizes that osteoarthritis in cats is more common than many owners realize (FDA, n.d.). Luckily, a range of supplements can help manage symptoms and support joint function.

Understanding Joint Health Supplements for Cats
When you’re picking a joint supplement for your cat, you need to understand the key ingredients and what they do. The goal is to reduce inflammation, protect cartilage, and improve overall joint function.
Key Ingredients in Cat Joint Supplements
- Glucosamine and Chondroitin: These are natural components of healthy cartilage. Supplementing with them can help repair and maintain cartilage, reducing pain and improving mobility. A study published in BMC Veterinary Research in 2026 evaluated a nutritional supplement containing glucosamine and chondroitin for alleviating osteoarthritis symptoms in cats (Bhathal et al., 2021).
- Omega-3 Fatty Acids (EPA and DHA): Found in fish oil, these have powerful anti-inflammatory properties that can significantly reduce joint pain and stiffness. A 2026 systematic review and meta-analysis showed the benefits of omega-3 enriched diets for cats with osteoarthritis (Corbee, 2022).
- MSM (Methylsulfonylmethane): A natural sulfur compound known for its anti-inflammatory and pain-relieving effects.
- Green-Lipped Mussel (GLM): A source of omega-3s, glucosamine, and chondroitin, which means it tackles joint health from several angles.
- Hyaluronic Acid: A component of synovial fluid, which lubricates joints. Supplementation can improve joint lubrication and shock absorption.
