Chondroitin is a molecule that occurs naturally in the body. It is a major component of cartilage, the tough, connective tissue that cushions the joints. Commercial chondroitin comes from natural sources, such as shark and bovine cartilage, or synthetic production. Chondroitin helps keep cartilage healthy by absorbing fluid (particularly water) into the connective tissue.
Glucosamine and chondroitin are both natural substances produced by your body.
