Product Review

Best MSM features Optimism, a highly purified form of methylsulfonyl methane (MSM). Also known as methyl sulfone or dimethyl sulfone (DMSO2), MSM contains two oxygen atoms and two methyl groups bound to a sulfur atom. The sulfur, which makes up about 34% of the elemental weight of MSM, is a part of the global sulfur cycle that results in plants taking up MSM from the rain and becoming a concentrated source of the compound. Unlike its parent compound dimethylsulfoxide (DMSO), MSM doesn't contribute to unpleasant after-effects such as garlic-like breath. Methylsulfonylmethane is widely distributed in nature and found in trace quantities among many foods, and in relatively higher quantities in a few foods and beverages, most notably Swiss chard, concentrated tomato products, milk, coffee, beer, port wine, and tea. Since the amount of MSM found naturally in living materials is too small to be extracted, the MSM used for dietary supplements is manufactured. The makers of Optimism developed a four-stage process to separate impurities including heavy metals and other contaminants from Optimism. Each batch exceeds the United States Pharmacopeia (USP) monograph standards for MSM, and is validated by testing in independent laboratories.
