MSM, (methylsulfonylmethane) provides sulfur, a vital building block of joints, cartilage, skin, hair and nails, and methyl groups, which support many vital biochemical processes in the body, including energy production.
Consistent quality and purity is their goal. Thats why OptiMSM® is produced in the only single-purpose MSM production facility in North America thats certified compliant with Good Manufacturing Practices (GMP). No pesticides or herbicides are involved in the raw materials or the manufacturing process. There are no Genetically Modified Organisms (GMOs) used in this product, nor is there exposure to common allergens or aflatoxins. Further, to ensure a purity level of greater than 99.9%, they confirm every batch through an independent laboratory and report the findings on a detailed certificate of analysis. Additionally, OptiMSM is certified halal and Kosher. The lengths they go may seem excessive to some, but to us, they feel just right.
The quality and purity of OptiMSM® after four times distillation is evident when looking at the color of the powder. It is pure, i.e., free of contaminants. Other methods show the contaminants left behind during the distillation process mostly comprised of heavy metals. These contaminants are all still present in the crystallization method, and although this cheaper MSM may look white and the manufacturer may claim 99% pure MSM, small quantities of heavy metals and other contaminants will be present in this imported MSM.
The bottom line is that heavy metals in OptiMSM® are guaranteed to be thousands of times lower than the levels in the cheaper import MSM. While it is not possible for consumers to verify this, selecting OptiMSM is a sure way to guarantee that you buy pure, clean MSM.
Originally, all MSM was produced in the US by Bergstrom Nutrition (previously Cardinal Nutrition). Bergstrom Nutrition is the only dedicated GMP MSM production facility in the world, eliminating the risk of contamination from toxins like benzene, toluene or pesticides. Bergstroms MSM is called OptiMSM. In the past several years, however, MSM is also produced in plants in China and India and Canada and is imported into the US and EU under the same generic name but for prices that are less than one-fifth of the Bergstrom Nutrition made MSM. OptiMSM is pharmaceutical grade quality MSM, and is produced by the method of distillation. This process removes any potential impurities, leaving only pure MSM, i.e. OptiMSM. The quality is supported by a certificate of analysis for each batch produced, which shows that bacteria and yeasts are absent. The concentrations of heavy metals, an important potential contaminant, is specified to be absent near the analytical levels of detection (for mercury, for example, at less than 0.001 parts per million).
Other producers use the crystallization method, which is a less expensive production process. In this process, the MSM is dissolved in water and then dried, trapping any contaminants present in the water. This MSM comes with certificates of analysis in which the absence of yeast, bacteria and fungi is often not guaranteed, and the concentrations of heavy metals is shown as a generic group at less than 20 parts per million.
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.
