Glucosamine Definition

Glucosamine is a naturally occurring compound found in healthy cartilage that surrounds the joints. It is a component of both the cartilaginous matrix and the synovial fluid that work together to cushion the joints and facilitate smooth movement.

Glucosamine is often taken in combination with chondroitin, another component of articular cartilage. Some studies have shown that supplements such as glucosamine and chondroitin sulfate may be an effective treatment for osteoarthritis, especially osteoarthritis of the knee.
