General Description
Methylsulfonylmethane (MSM), also known as dimethyl sulfone, is
a naturally occurring sulfur compound present in all living organisms.
MSM is an odorless, essentially tasteless, water-soluble, white,
crystalline substance that contains approximately 34 percent sulfur
by weight. Although it is found in many foods, including milk, meat,
fish, fruits, vegetables and grains, MSM is readily lost when foods
are processed or cooked. Supplemental MSM is synthesized from paper-processing
by-products.
Health applications
Primary functions
MSM serves as a highly absorbable source of organic sulfur, which
is an essential mineral component for many amino acids, vitamins,
antioxidants, and enzymes. The body needs sulfur to form the bonds
that hold tissues together, making it important for healthy cartilage,
ligaments, tendons, skin, hair, and nails. Supplemental MSM is
popular among arthritis sufferers for promoting joint tissue repair.
Topical formulations, such as lotions and creams, are used to
promote skin health. At this time, no large-scale, human studies
have been conducted to examine the role of MSM in the treatment
of any disease or condition.
Dosage/toxicity
MSM is commonly supplemented in doses of 2,000 to 6,000 mg per
day, and has an excellent safety record at this dosage range.
There is no RDA for sulfur or MSM, and no toxic dosage has been
determined. |
