This product is MSM imported from China and is certified to be 99.9% pure or better. It is purified using the double-crystallization method rather than the distillation method used by our US-made OptiMSM. Distillation is considered to be a superior method, thus why OptiMSM is priced significantly higher. Although this product does come from China, we don't have any reservations recommending it for those on a budget. And just as in our brand-name products, there are no fillers or additives in this product. It is about the consistency of sugar.
OptiMSM® is manufactured in Washington by Bergstrom Nutrition (formerly Cardinal Nutrition) at a facility that Bergstrom owns and is dedicated only for making MSM. Since theirs is a closed system, things like temperature and humidity are more controlled and theirs is a more consistent product from lot to lot. Their plant is NNFA GMP certified. They also obtain their DMSO from any number of countries. OptiMSM® is also certified as pure and free of contaminants and heavy metals. Bergstrom does pay royalties to the MSM patent holder, MSM Investments Company, LLC., but is not the patent holder itself. Dr. Stanley Jacob, one of the authors of The Miracle of MSM – The Natural Solution for Pain, has given his endorsement to the OptiMSM® brand.
