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.

The reason that doctors have not been doing this for human patients is yet another topic outside the scope of this article.ther names for glucosamine are: glucosamine sulfate, glucosamine sulphate, glucosamine hydrochloride, N-acetyl glucosamine, chitosamine. Glucosamine is a compound found naturally in the body, made from glucose and the amino acid glutamine.
