Optimized Plant Mediated Solutions has been the leader in the Kratom and Kava extracts since 2010 due to its exclusive cold process extractions. OPMS mainly focuses on making powder, capsules, and liquid kratom. They do not sell in bulk or loosely, only in packaged goods. What sets OPMS at the top of kratom products is that focus a lot on protecting as many alkaloids as possible within each end every plant. Every plant is handled with the most precise case and attention at O.P.M.S. Another careful step they take is only using cold water with the plants to secure maximum alkaloid content.
