- 7-OH is a potent alkaloid associated with the kratom plant.
- Concentrated products are dosed in milligrams — a totally different scale than leaf powder.
- Potency is why exact labels and lab tests matter so much.
The 30-second version
7-hydroxymitragynine (7-OH) is an alkaloid found in trace amounts in kratom (Mitragyna speciosa) and produced in concentrated form for modern flavored products. It acts on mu-opioid receptors in the brain, which is why it produces strong, opioid-like effects at higher servings and carries the dependence and respiratory-depression risks covered in our safety rules.
The Food and Drug Administration has not approved 7-OH or kratom products for any medical use; everything on this site is sold as a packaged adult product, not medicine.
7-OH versus mitragynine versus kratom leaf
Mitragynine is the dominant alkaloid in kratom leaf; 7-hydroxymitragynine is present there only in small quantities. Concentrated 7-OH products like Ultra Seven chewables contain a labeled milligram amount of the alkaloid in each piece — 7mg to 80mg — which is a completely different scale from brewing grams of leaf powder. Kratom vs 7-OH walks through the practical differences.
The federal government explicitly treats concentrated products and botanical leaf separately in its 2026 scheduling notices — see the federal status tracker.
Why the milligram label exists
Because potency is high, the entire industry’s safety model depends on exact, tested labels: a 7mg tablet, a 20mg tablet, a 10mg strip, and an 80mg single are deliberately different products. The strength guide and dosage chart exist to keep buyers on the right row of the table.
