MSM is a natural part of every cell function and is concentrated in the connective tissues of the skin, nails, and hair. MSM is a source of organic sulfur and is a key nutrient for its diverse health benefits. Though MSM is found in many fresh foods, modern agricultural methods and food processing cause its depletion. This makes it difficult to get adequate amounts of MSM in the daily diet. Rich's MSM helps restore the body balance with a needed natural source of sulfur for support.
