What 7-OH is

7-OH is short for 7-hydroxymitragynine, one of the alkaloids in the leaf of kratom (Mitragyna speciosa), a tropical tree in the coffee family native to Thailand, Malaysia, Indonesia and Papua New Guinea. In the raw leaf it is a minor alkaloid, usually well under one percent of the total alkaloid content. The body also forms small amounts of it from mitragynine, kratom's main alkaloid.

7-OH and kratom are not the same thing

Kratom leaf powder contains dozens of alkaloids, mostly mitragynine, with only traces of 7-OH. Products sold as 7-OH are different: they are made by concentrating or converting kratom alkaloids so that 7-OH is the main active ingredient, at amounts far above anything in the leaf. Treat a 7-OH product as its own thing, not as a stronger kratom powder.

Legal status

Rules for 7-OH are changing quickly. In July 2025 the U.S. Food and Drug Administration recommended that 7-OH be scheduled under the federal Controlled Substances Act, and a number of states and cities have banned or restricted it. Alkaline Club does not ship to AL, AR, IN, RI, VT, WI, and checkout blocks those addresses. Check the current law where you live before you order; we update this list as laws change.

Safety basics

7-OH acts on the same receptors in the body as opioids, and regular use can lead to dependence and withdrawal. Do not combine it with alcohol, opioids, benzodiazepines, sleep aids or other sedating drugs, and do not drive or operate machinery after use. Do not use it if you are pregnant, nursing, under 21 or taking prescription medication without asking your doctor first. Keep it locked away from children and pets. Read the full label before use.
