Glucosamine is a form of amino sugar that is believed to play a role in cartilage formation and repair. Extracted from crab, lobster or shrimp shells, it is sold in the United States as a dietary supplement.

Glucosamine has been studied as a therapeutic agent for many years, but only in the past decade has become popular for treating osteoarthritis.

Found in high concentrations in the joints, it has been theorized that glucosamine stimulates the formation of cartilage that is essential for joint repair.

Short term controlled studies have found glucosamine effective in relieving pain in patients with osteoarthritis and for increasing their range of motion.

Definitive results about the effects of glucosamine are expected from an in-depth clinical study currently being conducted by the National Institutes of Health.

While many doctors now believe it is worth trying glucosamine for osteoarthritis, they caution that the quality and effectiveness of glucosamine varies because of the non-regulation.

If you want to try it, buy a high quality product from a reputable source.
