Methylsulfonylmethane has been present in the oceans, soil, and atmosphere of the Earth for eons. Organic sulfur (MSM) occurs naturally in the human body. It actually makes up 5% of the human body and is essential for every organ, cell, tissue, hormone, enzyme, antibody, and function found in the body. This whole food is a beautifying mineral, and contributes to hair, skin, nail, and joint renewal and health. Bio-available, MSM must be continually replenished for optimal youth, nutrition and health. A wonderful additive to have in EVERY product.
