MSM, short for methylsulfonylmethane, is an organic sulfur compound that occurs naturally in many plants and in animals, including humans. This substance supports joint health and the immune system via multiple pathways, yet it is difficult to get a therapeutic benefit from diet alone. Therefore, MSM is available as a dietary supplement. It is also a cosmetic ingredient in various skin care products.
