HorseTech has used one, and only one, source of MSM since the day that we opened--OptiMSM® from Bergstrom Nutrition (formerly Cardinal Nutrition). While Bergstrom offers a less-expensive MSM alternative targeted for the animal markets (PurforMSM®), HorseTech continues to offer only the very best MSM available anywhere--OptiMSM®. Fully licensed and made to the original patent, OptiMSM is made for human consumption right here in the U.S.A.--it doesn't get any better!
 
Unlike most imported MSM, HorseTech's OptiMSM® is made with a unique distillation process where contaminants are "distilled" away from the final product. You'll note that the distilled product is a fine white powder, whereas the cheaper, evaporated product will generally be a larger, less consistent "flake" material. Further, each and every batch of OptiMSM® is tested right here in the U.S. for heavy metal contaminants AND microbiological contaminants. This is an important part of the quality assurance program! Look for the OptiMSM® logo!
