MSM is a natural chemical found in green plants such as Equisetum arvense, certain algae, fruits, vegetables, and grains. In animals, it is found in the adrenal cortex of cattle, human and bovine milk, and urine. MSM is also found in human cerebral spinal fluid and plasma at 0 to 25 mcmol/L concentrations. MSM is naturally occurring in fresh foods. However, it is destroyed with even moderate food processing, such as heat or dehydration. MSM has been suggested for use as a food supplement and is available in the United States as a dietary supplement.
MSM is the normal oxidation product of dimethyl sulfoxide (DMSO). Unlike DMSO, MSM is odor free and is a dietary factor. MSM has been referred to as “crystalline DMSO.” It provides a dietary source of sulfur for methionine. MSM’s medicinal properties are theorized to be similar to those of DMSO, without the odor and skin irritation complications.
