Methylsulfonylmethane (MSM) is a naturally occurring organic sulfur compound
that is found in all living plant and animal tissues. Sulfur, the primary functional molecule of MSM, is involved in many enzymatic and biological components in the body. While sulfur is naturally found in foods, it is easily destroyed by even minimal processing. Preliminary research suggests MSM may have the ability to improve joint health, making it a very popular supplement among seniors.
