Benefits of Glucosamine for Cats

Glucosamine is a natural substance that is found in the bodies of both humans and animals. It is a building block of cartilage, and it plays a role in the maintenance and repair of joint tissue. As animals age, their bodies may produce less glucosamine, which can lead to joint problems such as osteoarthritis. Supplementing with glucosamine may help to reduce inflammation and improve joint function in dogs and cats.

Cartilage & Joint Tissue

Glucosamine is primarily found in cartilage. Cartilage is a smooth, rubbery tissue that covers the ends of bones in a joint. It provides cushioning and support, and helps to reduce friction between the bones. Glucosamine is a key component of cartilage, and it is involved in the production and maintenance of this tissue.

Glucosamine is also found in other tissues in the body, including in the synovial fluid that surrounds the joints. Synovial fluid is a lubricating fluid that helps to reduce friction and wear on the joint surfaces. It is produced by the synovial membrane, which lines the joint capsule and encloses the joint cavity.


There is some evidence to suggest that glucosamine is helpful in reducing inflammation and pain associated with osteoarthritis, a common degenerative joint condition that affects dogs and cats as they age. It also helps to slow the progression of the disease by supporting the repair and maintenance of joint cartilage. Numerous studies have found that glucosamine supplementation provides benefits for dogs with osteoarthritis (Gupta, Canerdy, Lindley, Konemann, Minniear, Carroll, Dang, & Bagchi, 2012). These studies involved giving glucosamine supplements to a group of dogs with osteoarthritis for a period of six to twelve weeks, and evaluating the dogs’ clinical signs, including pain, mobility, and lameness. The research showed that the groups receiving glucosamine supplements experienced significant improvement in clinical signs compared to the control group.


Glucosamine supplements are generally considered safe for use in dogs and cats, although it is important to follow the recommended dosage and to consult with a veterinarian before starting your pet on any new supplement. Some studies have shown that glucosamine may be more effective when used in combination with other supplements, such as chondroitin and MSM (methylsulfonylmethane).

As with any supplement, it is important to discuss the use of glucosamine with your veterinarian to determine if it is appropriate for your animal and to ensure proper dosing.
