Glucosamine is a naturally occurring amino sugar synthesized in the body from L-glutamine and glucose. Glucosamine stimulates the manufacture of glycosaminoglycans, important components of the cartilage needed for healthy joints.40,41 Aging people seem to lose their ability to produce a sufficient amount of glucosamine, and there are no food sources available. Commercial sources of glucosamine are from the exoskeleton of certain shellfish and are available as gluco-samine sulfate, gluco-samine hydrochloride, and N-acetyl-glucosamine. The sulfated form may most effectively incorporate sulfur into the cartilage.42,43
Glycosaminoglycans and glycoproteins allow cells in tissues to hold together. They are necessary for the construction and maintenance of virtually all connective tissues and lubricating fluids in the body.44,45
