Glucosamine sulfate

Glucosamine is a compound made in the body from various sugar molecules. It is important to joint health and integrity. Most glucosamine supplements are derived from the shells of shellfish or it can be made in the lab. In osteoarthritis, the surface layer of cartilage between the bones of a joint wears down. This allows the bones to rub together, which can cause pain and swelling and make it difficult to move the joint. The knees, hips, spine, and hands are the parts of the body most likely to be affected by osteoarthritis.
