Now Foods Vegetarian Glucosamine & Msm , Veg-Capsules, 240-Count

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's unique and synergistic formula is suitable for;vegetarians, because it contains only Glucosamine from a vegetarian source and not from shellfish.
