What is 7-OH?

The short answer

7-OH (7-hydroxymitragynine) is an alkaloid — a naturally occurring compound — linked to the kratom tree, Mitragyna speciosa, which is native to Southeast Asia. Kratom leaf contains only trace amounts of 7-OH. The 7-OH products sold today are concentrated: they put a measured amount of 7-OH into each tablet or serving, so they're far more potent per serving than kratom leaf.

Where 7-OH comes from

Kratom's most abundant alkaloid is mitragynine. 7-OH is a minor alkaloid in the leaf, and it's also what the body produces from mitragynine. Because the leaf holds so little of it, products built around 7-OH are generally made by concentrating or converting mitragynine rather than by grinding up leaf.

That's the key difference from kratom powder or capsules — see 7-OH vs kratom for a side-by-side comparison.

How 7-OH products are sold and labeled

• Forms: mostly chewable or swallowable tablets, sometimes shots or other servings.
• Labeling: strength is listed in milligrams (mg) of 7-OH per tablet or serving, and often a total per pack. Tablets in our lineup range across 60mg/tab, 30mg/tab, 30mg, 40mg, 100mg per tablet.
• Lab testing: reputable products are tested by an independent lab, which issues a certificate of analysis (COA) confirming the 7-OH content and checking for contaminants. Learn how to read a COA.

Because servings are measured in milligrams, the number on the label matters. Compare products by mg per tablet and total mg per pack — every product page in our lineup shows both, plus the price per mg.

Is 7-OH legal?

It depends on where you live, and it's changing fast. 7-OH is not approved by the FDA for any use. In 2025 the FDA recommended that 7-OH be placed under federal drug control, and a growing number of states and cities ban or restrict it. We don't ship to Alabama, Arkansas, Connecticut, Florida, Indiana, Kansas, Louisiana, Tennessee, Vermont and Wisconsin, and our checkout blocks restricted addresses automatically.

Safety basics

• For adults 21 and over only. Keep it away from children and pets.
• 7-OH is potent, and regular use can lead to dependence.
• Don't combine it with alcohol, opioids, benzodiazepines or other sedatives.
• Don't drive or operate machinery after use.
• Don't use it if you're pregnant or nursing, and talk to a doctor first if you take any medication.
• Follow the serving size on the label and buy only lab-tested products from sellers who'll show you the COA.
