O.P.M.S.® Silver Kratom Powders Optimized Plant Mediated Solutions Silver Products. O.P.M.S. fine screens all Kratom batches to remove any foreign objects and tests for heavy metals, feces, salmonella, and mold content. O.P.M.S. products are then sterilized for further public safety. O.P.M.S. has developed a state-of-the-art process of pulverizing to produce a very fine Kratom powder. This process increases the surface area of the Kratom powder, making it much more desirable to customers. This also allows O.P.M.S. to compact more powder into a smaller capsule. * These statements have not been evaluated by the Food and Drug Administration.
