“Kratom extract” and “7-OH” both land on the concentrate shelf, and both promise more alkaloid per serving than leaf — but they’re not the same product class. Ratio-labeled extracts are blends; 7-OH products are targeted isolates. This comparison breaks down the alkaloid profiles, what the labels really say, and how to verify either one before you buy.
The two product classes, precisely
Kratom extract (often sold as 5:1, 10:1, 20:1, etc.) is Mitragyna speciosa material processed to concentrate its entire alkaloid profile. A “10:1” label means roughly ten parts of leaf went into one part of extract — it tells you the processing ratio, not the exact alkaloid breakdown. The result is still a mix: mitragynine-dominant, with 7-hydroxymitragynine and minor alkaloids in whatever proportions the source leaf had.
7-OH products go one step further: the 7-hydroxymitragynine fraction is isolated and made the labeled dominant compound. A tablet marked “100mg 7-OH” means 100mg of 7-hydroxymitragynine per unit — a specific compound, a specific quantity, not a ratio. That’s the whole distinction in one sentence: extracts concentrate a profile; 7-OH products specify a compound.
Side by side
| Kratom extract (ratio-labeled) | 7-OH isolate (mg-labeled) | |
|---|---|---|
| Headline compound | Mitragynine + full profile | 7-hydroxymitragynine dominant |
| Label unit | Ratio (5:1, 10:1…) | Milligrams of 7-OH per unit |
| What varies batch to batch | All alkaloid percentages | Should be only the measured 7-OH value |
| Key verification | COA alkaloid panel | COA 7-OH value vs printed mg |
| Typical format | Powder, capsules | Tablets, chewables |
| Dose control | Grams of a mix | Exact mg steps (50 / 100) |
Why the alkaloid profile matters to the buyer
Because 7-hydroxymitragynine is the more potent of the two headline alkaloids at opioid receptors, an extract’s 7-OH percentage is quietly one of the biggest drivers of how that extract feels — and it’s the number most extract labels never print. A 10:1 from one region’s leaf is not a 10:1 from another’s. With a 7-OH isolate, the relevant percentage flips: the product should be almost entirely the labeled compound, and the COA is where you confirm it. That’s why our COA reading guide spends the most time on the single line that matches the pack’s claim to the lab’s measurement.
Our broader mitragynine vs 7-OH post covers the chemistry behind the potency difference, and what’s stronger than kratom puts “stronger” into its three real definitions so vendor superlatives stop sounding like measurements.
Buying either class: the shared rules
- COA per batch, not per brand. Ratio or milligram, if the batch can’t be tied to a lab report, the label is a suggestion.
- Adults only. Both classes are 21+ products. No legitimate vendor sells either to minors, and 21+ verification should happen at checkout and delivery.
- Legal check first. Extract and 7-OH products sit under different state rules in 2026 — several states restricted or banned 7-OH specifically in the past year. Read the current legal map before ordering, and check our shipping FAQ for where we can and can’t ship.
- Responsible use, same rules. No mixing with other depressants, no machinery after use, and a break-schedule for regular use — our responsible use guide applies to both classes.
Bottom line
If you want the traditional profile in concentrated form, a verified extract with a full alkaloid-panel COA is the format. If you want the more potent alkaloid as a defined, step-able dose, a 7-OH isolate with a batch-matched COA is the format — and it’s the one we build: 50mg and 100mg lines, every batch lab-verified, 21+ only.
