Methylsulfonylmethane, or MSM, is a water-soluble, solid compound, also known as dimethyl sulfone. It is a direct metabolite of dimethylsulfoxide (DMSO) and is sometimes called DMSO2. MSM is a source of biological sulfur, which is a major component in many of the body’s proteins, tissues, hormones, and enzymes. Sulfur is plentiful in all living organisms, amounting to about 2% of the dry weight of most animals. Through the formation of disulfide bonds, sulfur is the foundation for the proper conformation of extracellular body proteins, holding connective tissue together as well as maintaining the structure of antibodies and hormones. Large amounts of sulfur are found in hair and nails, and sulfur plays a role in the detoxification of the liver.* Intracellular sulfhydryl (thiol) groups are also vital for the catalytic function of many enzymes.*

Suggested Use

As a dietary supplement, 1 to 3 capsules one to five times daily, or as directed by a healthcare practitioner.


Keep in a cool, dry place, tightly capped.
