Recently, more and more people suffer from osteoarthritis, an often painful condition in which the cushioning cartilage between bones wears away. Because so many live fast-paced lifestyles, there is less time for exercise. This has been a contributing factor in the increasing cases of osteoarthritis each year. Many people are trying new supplement and therapies for relief, and chondroitin sulfate is a wise choice.

Chondroitin sulfate is a sulfated glycosaminoglycan (GAG) composed of a chain of alternating sugars (N-acetylgalactosamine and glucuronic acid). It is usually found attached to proteins as part of a proteoglycan. A chondroitin chain can have over 100 individual sugars, each of which can be sulfated in variable positions and quantities. Chondroitin sulfate is an important structural component of cartilage and provides much of its resistance to compression. Because of its special property, chondroitin sulfate has become a widely used dietary supplement.

The primary source of chondroitin sulfate is mainly from animal cartilage, such as birds, sharks, and other fish. The precise composition of chondroitin sulfate supplements vary considerably, since it isn’t from one specific source.
