Glucosamine and Chondroitin both provide the essential structural material glycosaminoglycans, which are required for healthy cartilage, promoting mobility, range of motion, flexibility and to ease occasional joint stress due to exercise or physical activity. MSM (Methylsulfonylmethane) provides a natural, bioavailable source of sulfur, an important mineral that also supports healthy collagen, connective tissue, joint cartilage and joint mobility. MSM works synergistically to increase the benefits of glucosamine and chondroitin.* This formulation also provides Hyaluronic Acid. Individual Results May Vary.
