MSM is found in all living plant and animal tissues. A precursor of MSM is formed initially by ocean plankton and released into the atmosphere, where it interacts with ozone and sunlight and returns to earth as MSM in rainfall. MSM is absorbed by plants and in our foods. To date, no measurement of the MSM content of foods has been done. 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. It helps support joint flexibility, cellular fluid balance and healthy skin, hair and nails.
