Glucosamine is an amino sugar that the body naturally produces and distributes in cartilage and other connective tissue to stimulate cartilage building. Chondroitin sulphate is a complex carbohydrate and a basic building block of cartilage.

Both glucosamine and chondroitin are structural components of cartilage that cushions the ends of bones within the joints. They are produced by the body naturally and also available as dietary supplements.
