You’ve seen 7-OH in searches, on store shelves, and in group chats, and the name itself is a mystery: an element symbol, a dash, a number. This guide pulls the label apart so a first-time buyer knows exactly what they are looking at — and what to check before ordering anything.
What the name actually means
Kratom comes from Mitragyna speciosa, a tropical tree in the coffee family. Its leaves contain dozens of natural compounds called alkaloids. The two most discussed are mitragynine and its naturally occurring relative 7-hydroxymitragynine — which is where the name comes from: the 7-hydroxy prefix describes a specific chemical modification of the mitragynine structure. In industry shorthand, people say 7-OH for 7-hydroxymitragynine.
Here’s the part that matters for buying: in raw leaf, 7-hydroxymitragynine is present only in trace amounts. The products sold as “7-OH” are alkaloid extracts — lab-processed concentrates where 7-hydroxymitragynine is the dominant measured compound. That’s why a tablet labeled “100mg 7-OH” is a completely different thing from a pouch of kratom powder, even though both trace back to the same plant.
Why buyers moved from leaf to 7-OH products
Three practical reasons show up in every serious comparison:
- Dosing precision. Raw leaf varies batch to batch and even bag to bag. A tablet or chewable with a printed milligram value is a fixed unit. If the label says 50mg, the lab should be able to prove it — which is exactly what a certificate of analysis is for.
- Concentration. Extracts contain far more of the target alkaloid per gram than leaf, so the amounts involved are small, measured, and consistent.
- Convenience and discretion. Tablets store cleanly, measure cleanly, and travel in a pouch — no grinding, no brewing, no loose-leaf storage questions.
It’s worth being clear about what 7-OH is not: it is not a medicine, it is not FDA-approved for anything, and nobody — including us — should describe it as treating or preventing any condition. It is an adult botanical extract product, and it carries the same responsible-use expectations as any concentrated plant alkaloid.
What a legitimate 7-OH product looks like
When we evaluate any 7-OH brand — ours included — we check the same four things every time:
- Batch-verified COA. A real lab report, tied to a batch number printed on the pack, showing measured 7-hydroxymitragynine content and contaminant screens. Our COA reading guide walks through exactly what those numbers mean.
- Honest strength labeling. “100mg” means 100mg of 7-hydroxymitragynine per tablet — not 100mg of a blend where the active alkaloid is a fraction of that.
- Adult-only policy. Reputable sellers enforce 21+ at checkout and delivery, and they say so plainly.
- Legal transparency. 7-OH’s status is changing in 2026, so a serious seller publishes its position on where 7-OH stands federally and state by state, and ships only where it’s permitted.
7-OH vs the other kratom world, in one table
| Format | Active compound | Dosing | Consistency |
|---|---|---|---|
| Raw leaf / powder | Mainly mitragynine, traces of 7-OH | Grams, variable | Batch-dependent |
| 7-OH extract (tablets, chewables) | 7-hydroxymitragynine dominant | Printed mg per unit | Lab-verifiable per batch |
| General extract | Mixed alkaloids, % labeled | Grams or mg of blend | COA-dependent |

The bottom line for new buyers
7-OH is a concentrated 7-hydroxymitragynine extract product sold primarily as tablets and chewables. The name is chemistry shorthand, the market is young, and the difference between a responsible vendor and a sloppy one shows up in the paperwork: batch COAs, honest mg labeling, 21+ enforcement, and a published legal position. Get comfortable with those four checks and you’re already ahead of most of the market.
