Best Cat Arthritis Supplements Summary

How do Supplements Help with Cat Arthritis?

Cat arthritis supplements help pets with feline osteoarthritis on various levels – from supporting healthy joint structures to reducing inflammation to preventing cartilage damage.

Cailin Heinze, VMD, assistant professor of nutrition in the department of clinical sciences at the Cummings School of Vet. Medicine at Tufts University supports the use of dietary supplements in the management of feline osteoarthritis.

She states that “these substances may improve comfort in some situations—perhaps through an anti-inflammatory mechanism and if you’re using a high-quality product from a reputable source—a product that actually contains what the supplier says it contains—then the safety level is pretty high.”

What Supplement Can I Give My Cat for Arthritis?

There are many cat arthritis supplements on the market. High-quality supplements usually feature the same ingredients. Here we will review the best ingredients found in cat supplements for joint health.

CBD Oil. Pet CBD oil is helpful for cats with arthritis. It promotes healthy joints, alleviates pain, and reduces inflammation within the joints. Plus, it comes with rare and mild side effects. CBD products for arthritic cats are available in the form of oils, capsules, and treats. We suggest the Honest Paws CBD Cat Treats and CBD oil. CBD products are among the most popular cat arthritis supplements. 

Glucosamine. Glucosamine is one of the main building blocks of joint cartilage. Research shows it supports cartilage renewal by stimulating a more intense synthesis of proteoglycans. Glucosamine supplements are available in several forms, including chews, capsules, powders, and liquids. 

Chondroitin. Chondroitin sulfate is a glycosaminoglycan that is present in cartilage. It supports joint health by increasing cartilage elasticity, promoting adequate shock absorption, and giving nourishment to the joint structures. Chondroitin and glucosamine act in synergy – they boost each other’s effects.

Green Lipped Mussel (GLM). Green Lipped Mussel is the perfect joint supplement because it has strong anti-inflammation and antioxidant properties. Plus, they contain a number of joint-friendly compounds like glucosamine, chondroitin, and omega-3 fatty acids. GLM extract supplements are available as powders that you can add to the cat’s food and tablets.

Omega-3 Fatty Acids. Omega 3 fatty acids are helpful for arthritic cats because they have proven anti-inflammation properties which may be effective in easing joint pain. One study showed that in comparison to the placebo group receiving corn oils, cats supplemented with fish oil were making higher jumps, more active, less stiff, and less reluctant to go up and down the stairs.

Hyaluronic Acid. Hyaluronic acid is a naturally occurring compound that helps maintain the sticky consistency of your cat’s joint fluids. It holds water which helps with joint lubrication. Additionally, it adds strength to the connective tissue and reduces inflammation. This helps keep your pet active overall. This supplement is available in both oral and injectable forms.

Methylsulfonylmethane (MSM). MSM is another cat joint supplement often used in combination with glucosamine and chondroitin. This has several benefits for joint-related problems in both cats and dogs. This supplement has antioxidant and anti-inflammatory properties. Plus, it strengthens connective tissues.

Boswellia. This is an ayurvedic herbal medicine called Boswellia serrata or Indian frankincense. It supports joint health by reducing inflammation and improving blood flow. Boswellia is usually combined with other cat arthritis supplements and come in the form of powders and cat treats.
