Researchers have been studying the effects of MSM upon the body for more than 20 years. This research, along with the pioneering work of Stanley W. Jacob, M.D., the Gerlinger Professor of Surgery at the Oregon Health & Science University, reveal the MSM supports many structures and functions of the human body. Because of this, supplementing the diet with pure, food-grade OptiMSM may result in a variety of health benefits. Respiratory Health MSM helps the body maintain its natural barriers against allergens, which fortifies the body's defenses against pollen, dander and allergenic foods. By providing sulfur, MSM supports the integrity of healthy mucous membrane tissue. Hair, Skin, and Nails Sulfur is necessary for the production of collagen and keratin. These are the primary proteins that make up hair, skin, and nails. OptiMSM supports tissue pliability and encourages the body's ability to repair damaged skin. Connective Tissue Sulfur is necessary for the formation of many basic body tissues including joints, ligaments, hair, skin, nails, tendons and the intracellular matrix in which all of the body's cells are supported and through which they communicate with one another. Carbohydrate Metabolism Sulfur is needed to produce insulin and other vital components that contribute to healthy carbohydrate metabolism. Gastrointestinal MSM promotes proper elimination and bowel function. These statements have not been evaluated by the Food and Drug Administration.
