Dimethyl Sulfone

Dimethyl sulfone (methylsulfonylmethane, MSM) is a normal oxidative metabolite found in the bloodstream and breastmilk. It is a metabolic product of endogenous methanethiol metabolism and intestinal Bacterial metabolism. No studies have been done on the use of dimethyl sulfone (MSM) orally in nursing mothers, but its low toxicity indicates that it is unlikely to harm the breastfed infant.
