what is msm in glucosamine

MSM stands for methylsulfonylmethane, which is a supplement used to ease the pain of arthritis. It is a sulfur-containing compound found in all living things and is needed by the body for healthy connective tissue and joint function. MSM has purported pain-quashing and anti-inflammatory properties and is often combined with glucosamine and chondroitin sulfate in supplements marketed for joint health. While MSM is found in many foods, it is destroyed when foods are processed, so MSM supplements have become increasingly popular in recent years. Some studies have reported improvement in pain with MSM, but more research needs to be done to support its use as an arthritis supplement.
