MSM capsules contain the sulfur-supplying compound methylsulfonylmethane, more commonly referred to as MSM. MSM is a naturally occurring substance found in plants, animals, and humans. Approximately half of the sulfur in the body is found in the muscles, skin and bones.
The amount of MSM found in foods exists in very low levels. Handling, processing and cooking foods can further deplete sulfur levels, leaving many people with suboptimal intakes of sulfur. Therefore, the structure and function of the human body can benefit from supplemental MSM.
Sulfur provided by MSM helps to promote joint health. It is necessary for making collagen, the primary constituent of cartilage, skin and connective tissue. Sulfur aids in the detoxification process by altering certain chemicals and making them water soluble, enabling them to then be excreted by the kidneys. Sulfur is also a factor in creating necessary components to rid the body of toxic metals and to protect cells.
