PurforMSM
Promote comfort and mobility in pets with PurforMSM®, the purest form of Methylsulfonylmethane (MSM), produced in the U.S. using a proprietary distillation process unmatched in the industry.
Other manufacturers purify MSM using crystallization, a wash and centrifuge process designed to separate impurities and byproducts introduced during manufacturing. As crystals form, occlusions (pockets) develop that can entrap contaminants present in the solution. The purity of the crystals depends on the quality of the water and the raw materials used in manufacturing.
By contrast, PurforMSM, is purified using a proprietary four-stage distillation process to provide the purest form of MSM available. Distillation uses heat to separate impurities through unique boiling points. Impurities and byproducts that boil below or above 478° F are removed during this process, leaving pure MSM and eliminating concerns for contamination or consistency.
