The kratom leaves used in our products are sourced from the farms and jungles of Southeast Asia and are handpicked and sorted by the local harvesters. The leaves are then dried and ground into a nano powder, resulting in an extremely fine botanical that's easy to use. The powder is tested for potency, heavy metals, and pathogens before being shipped to us in the United States. We run a second test for confirmation before hand-mixing the botanicals to achieve our desired blends, after which we run a third test to confirm alkaloid contents. No fillers or additives are ever used.
