Now Vitamins - M.S.M Powder 1 Lb

MSM is a natural form of organic sulfur found in all living organisms. Sulfur provides the chemical links needed by your body for numerous functions. While it is a natural componenet of almost all fresh fruits, vegetables, seafood and meat, food processing reduces sulfur levels, making supplementation more important than ever. NOW® MSM is tested to contain a minimum of 99.9% purity. It has been researched since 1979.
