Unique distillation method insures this is the purest MSM you can buy - period.

MSM (methylsulfonylmethane) is a form of organic sulfur found in small amounts in almost all living organisms, including body fluids and tissues, mother's milk and most plants. Sulfur is needed for the synthesis of vitamins and amino acids in the body, but natural MSM is often lost in food processing.

Unlike the MSM found in leading brands, Formula 707 PurforMSM™ powder is manufactured using a four-step distillation process that removes the unprocessed raw materials, heavy metals, toxins and microbes left behind by other methods. Made in America by the leading producer of MSM for human consumption, PurforMSM is as pure as modern science can make it. PurforMSM powder is 100% pure. A highly bio-available source of dietary sulfur, which is essential for healthy joints and ligaments.
