MSM (methylsulfonylmethane), also known as dimethyl sulfone (DMSO2) and methyl sulfone, is a powerful sulfur-containing compound that supports numerous health and wellness benefits, such as promoting a healthy anti-inflammatory response and easing discomfort. MSM is produced through a chemical reaction between dimethyl sulfoxide (DMSO) and hydrogen peroxide. People with allergies to sulfa-drugs can safely consume MSM because it does not contain sulfanomide, which causes allergic reactions as it’s metabolized.

All Purely Soothing products use OptiMSM®, which sets the industry standard for pure, safe and consistent MSM. It is the only GRAS-designated MSM currently available.
