Use and indications
Chondroitin is an acid mucopolysaccharide and is found naturally in cartilage and connective tissue. Supplemental chondroitin is used for the management of arthritis and is often given with glucosamine, for osteoarthritis.
Chondroitin is rapidly adsorbed from the gastrointestinal tract and the absolute bioavailability of an oral dose is about 15%. It is distributed into numerous tissues, with a particular affinity to articular cartilage and synovial fluid.
