What the brand says

Methylsulfonylmethane is a naturally sulfur-rich compound. Sulfur is important for the production of amino acids- the building blocks to protein. Because the human body is made up of large amounts of sulfur, and because the amount of MSM in the body decreases with age, it is important to supplement with a high-quality MSM in order to encourage the production of new cells. MSM has been shown to support healthy joints.
