MSM is a synthesized molecule consisting of 1/3 methyl, 1/3 sulfonyl (bio-available sulfur), and 1/3 methane. MSM is synthesized by mixing hydrogen peroxide with DMSO. The DMSO separates into dimethyl, and MSM. Dimethyl is a strong solvent, and MSM is a form of bio-available sulfur. Sulfonyl does not exist as a solid. It is a gas created in the ocean by plankton. It bonds with the methyl and methane in the atmosphere and becomes methylsulfonylmethane, MSM.
The crystalization method of producing MSM can create a contaminated product. Sometimes heavy metals remain with crystalization. Distillation is the key to pure MSM. Our MSM is distilled 4 times. It is the purest MSM available.
