HorseTech offers 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.!


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!


One scoop will provide approximately 10,000 mg of MSM
