Methyl-Sulfonyl-Methane (MSM) is an organic sulfur compound which is a metabolite of dimethyl-sulfoxide (D.M.S.O.). It is a white, odorless, slightly bitter tasting, crystalline substance, which contains 34 percent elemental sulfur. It is easily soluble in water. Its chemical formula is (CH3)2SO2.

Purity: 99%
Physical Form: Clear Crystals
Melting Point: N/A
Applications: Topical
Usage Rate: Up to 8% (start at a .5% or lower)
Solubility: Water
Organic: Yes

It has been suggested by Lovelock and his associate's (1) that M.S.M. and its related compounds D.M.S.O. and D.M.S. (dimethyl sulfide) provide 85 percent of the sulfur found in all living organisms. The cycle of these naturally occurring sulfur compounds begins in the ocean where microscopic plankton release sulfur compounds called dimethyl sulfonium salts. These salts are transformed in the ocean into the very volatile compound D.M.S. which escapes from the water as a gas which rises into the upper atmosphere. Exposed to ozone and high energy ultraviolet light the D.M.S. is converted to D.M.S.O. and M.S.M. Both the D.M.S.O. and M.S.M. are very soluble in water and they return to the surface of the earth in rainwater. Plants then take up the two compounds into their root systems concentrating them up to one hundred fold. M.S.M. (sulfur) is incorporated into the plant structure. Through the process of plant metabolism the M.S.M., along with the other sulfur compounds it has spawned, are ultimately mineralized and transported back to the ocean and the sulfur cycle begins again.
