What this latter term implies is that MSM provides the human body with the essential mineral sulfur. This designation is deserved as MSM is a form of sulfur found in the tissues and fluids not only in humans by all plants and animals. MSM is the major form of sulfur in the human body.
Sulfur is an important element for all cells and body tissues.
It is especially important nutrient for joint tissue where it functions in the stabilization of the connective tissue matrix of cartilage, tendons, and ligaments. As far back as the 1930s, researchers demonstrated that individuals with arthritis are commonly deficient in this essential nutrient. Restoring sulfur levels brought about significant benefit to these patients. Sulfur is also important to proper liver function, detoxification reactions, and for the action of insulin. There has not been enough scientific research on the therapeutic value of MSM, what does exist is very scanty research on its safety and effectiveness in arthritis, lupus, muscle pains, and promotion of wound healing.
