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 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.
- Provides a rich source of bioavailable sulfur, which supports the formation of important nutritional elements including glutathione, cysteine, and methionine
- May support the formation of healthy connective tissue
- May enhance the mucosal membranes
