Kratom extract for tablet manufacturing.
Standardized mitragynine (MIT) extract built for compression: consistent alkaloid content, documented lot to lot, in kilogram volumes from U.S. stock.
Why manufacturers press with standardized extract.
Kratom leaf powder typically contains only around 1–2% mitragynine, and the exact figure moves from batch to batch. Pressing a consistent tablet from leaf means large fill weights and constant reformulating.
Standardized extract at 75–80%+ MIT changes that. You hit your target MIT per tablet with a small fill weight, leave room in the tablet for excipients, and keep the number stable from one production run to the next, because every lot comes with a COA showing its actual MIT content.
Freebase or salt form?
Both are fine powders standardized to mitragynine. The right choice depends on your format and process. Your formulator should make the final call.
| Freebase | Salt form | |
|---|---|---|
| Mitragynine content | 80%+ (by HPLC) | 75%+ (by HPLC) |
| Water solubility | Lower | Higher |
| Fill weight per mg of MIT | Smallest | Slightly larger |
| Commonly chosen for | Standard compressed tablets and capsules | Formats where faster dissolution matters |
| Minimum order / packaging | 10 kg / 1 kg units | 10 kg / 1 kg units |
How much extract goes in each tablet.
Work from the MIT content on the lot's COA, not the minimum on the spec sheet. The calculation is the same for both forms:
For example, for every 100 mg of MIT in your formula, a lot testing at 0.82 (82%) needs about 122 mg of extract, and a salt-form lot testing at 0.76 needs about 132 mg. Recalculate whenever a new lot arrives, and build your blend-uniformity checks around the COA figure.
What to ask any MIT extract supplier.
Before you commit a production line to an extract, get clear answers to these. We provide all of them with every order.
A COA for every lot
From an independent lab, showing actual MIT content, not just a minimum spec.
7-OH reported
7-hydroxymitragynine content listed on the COA, which matters given current regulatory attention on 7-OH.
Contaminant testing
Heavy metals and microbials tested on each lot, so your finished goods start clean.
Supply continuity
Domestic inventory and a reserve position, so a delayed shipment overseas doesn't stop your press.
Your product, your label.
We supply the raw material and the documentation. Finished-product decisions stay with you and your formulator.
- We sell wholesale to verified businesses only.
- We do not ship to states or localities where kratom or its alkaloids are restricted.
- Manufacturers are responsible for their own serving sizes, labeling and product claims.
- Kratom rules change. Check federal, state and local requirements for every market you sell into.
Test it on your press before you commit.
