Now Foods Glucosamine And MSM - 120 Vcaps
Glucosamine is an essential substrate for the formation of glycoaminoglycans (GAG's) and proteoglycans, which are the main components of cartilage tissue. GAG's and proteoglycans trap and hold water, forming a dense fluid cushion within the joint and thus, provide lubrication and shock absorption. MSM (Methylsulfonylmethane) is a natural source of organic sulfur, a mineral necessary for the production of proteoglycans.*  NOW unique and synergistic formula is suitable for vegetarians, because it contains only Glucosamine from a vegetarian source and not from shellfish.
