MSM, or methylsulfonylmethane, is a natural source of organic sulfur, which is necessary for the formation of collagen and the manufacture of many proteins in the body, including those that form hair, muscles and skin. MSM supports joints and connective tissue by providing the sulfur they need for proper function. Many MSM supplements also contain glucosamine and chondroitin, two naturally-occurring substances that promote joint health.**
