If you buy anything in the kratom-adjacent world, you keep running into two names: mitragynine and 7-OH (7-hydroxymitragynine). Sellers use them interchangeably, labels mix them, and half the confusion in this market comes from not knowing which compound a product actually contains. Here’s the distinction, and how it changes what you should expect from a pack.
Same plant, two different compounds
Both are natural alkaloids from Mitragyna speciosa. In the leaf, mitragynine is the major alkaloid — typically the bulk of what you’d ingest from raw leaf or general powder. 7-hydroxymitragynine is a minor alkaloid in the leaf, present in small fractions of a percent, produced naturally in small amounts. They are related molecules, not the same molecule, and they don’t behave the same way at the body’s receptors: 7-hydroxymitragynine is generally described as the more potent and more selective of the two at opioid receptors.
The table that resolves most of the confusion
| Mitragynine (leaf / general) | 7-OH (7-hydroxymitragynine extracts) | |
|---|---|---|
| Where it’s the main ingredient | Raw leaf, powder, tea, general extracts | 7-OH-specific tablets & chewables |
| Typical dose scale | Grams of leaf/blend | Milligrams of isolated alkaloid |
| Relatively speaking | The baseline compound | More potent per mg at the receptor |
| Labeling to verify | % alkaloids, or just “kratom” | mg of 7-hydroxymitragynine per unit + COA |
| Consistency driver | Batch quality of the leaf | Lab analysis of the extract |
What “more potent” means at the point of purchase
Practically: because 7-OH is the stronger compound, a 50mg 7-OH tablet is not the same category as 50mg of kratom powder. The milligram unit refers to a concentrated, isolated alkaloid. Two buyer implications:
- Dosing logic. You titrate in small, exact steps (50mg → 100mg), and small changes are meaningful. With leaf, the same “step” is a guess.
- Verification burden. With leaf, a COA at least tells you the alkaloid percentages of a batch. With a 7-OH tablet, the COA must confirm the printed milligram value of the active compound — that’s the entire value proposition. If a seller can’t tie a batch to a lab report, the “mg” on the pack is a claim, not a fact. Our COA guide shows exactly which line to check.
Which one is “better”? It depends on what you’re buying
Neither compound is categorically better — they’re different products serving different buyers. Leaf and mitragynine-dominant formats suit people who want the traditional, whole-plant experience in gram units. 7-OH formats suit buyers who want precise, lab-verified dosing of the more potent alkaloid in a convenient tablet. Our head-to-head on format, cost per serving, and precision lives in 7OH Tablets vs Kratom Powder, and if you’re deciding between our two 7-OH strengths, the 50mg vs 100mg guide is the one to read.
One thing both categories share: this is an adult (21+) botanical extract market, not a pharmacy. No medical claims, no mixing with other depressants, and a clear legal check first — 7-OH’s status is state-specific and changing in 2026, so read the current legal map before you order anything.
