MSM powder is offered in two forms. MSM "coarse flakes" and MSM "fine crystals".

The coarse flakes powder form of MSM is totally FREE of ANY additives (such as silicon dioxide)! Because the particle are a little larger than the fine crystal powder, it takes a little longer to dissolve in water or orange juice. The advantage is, however, that you are taking pure MSM without any additives. MSM "coarse flakes" are Cardinal Nutrition's patented and superior form of MSM obtained by distillation instead of by crystallization. This technology ensures the highest quality of MSM on the market to-day, entirely free of any contaminants.

The fine crystal powder form of MSM is often preferred by people that like to dissolve the powder in a juice or in water. Since the crystals are extremely fine, they dissolve quickly. However, to avoid the MSM from clumping and becoming hard as rock upon exposure to moisture, a small amount (0.1%) of silicon dioxide (SiO2) is added as anti-clumping agent. Silicon dioxide is commonly used in food items and is completely non-toxic.

This premium quality, human grade methylsulfonylmethane is the only MSM made under license of US Patent 4,616,039 and other US and international patents. Unlicensed MSM is generally imported from China and has been produced by crystallization, an inferior technology which traps any contaminant in water. You can avoid the risk of these products by insisting on patented and pure OptiMSM.
