Lab Tested Kratom

Find your batch

The batch number is printed on your package. Match it to the report in the list above. You are reading the results for the exact bag in your hand, not a representative sample from some other run.

On our own packages the lot sticker carries the number and the table names it. On the brands we carry, the lot or batch code is printed inside the report itself, on the first page, so open the report and match it there.

Scanned the QR code on a Whole Earth package? It brought you here. Find your batch number on the label and match it to the list.

Older reports stay up permanently. If you have a package from two years ago, its report is still here.

Whose report is this?

Two kinds of document sit in the list above, and it’s worth knowing which one you’re reading.

Our house product is tested by a laboratory we commission ourselves, so our name is the client on the report.

For the brands we carry, the manufacturer commissions the testing and the manufacturer’s name is the client. We hold those reports, we read them, and we publish them here where a customer can read them too. We don’t present them as our own work, and a seller who blurs that line is taking credit for a document somebody else paid for.

Either way the laboratory is independent of whoever is selling you the product, which is the part that matters.

What the lab report covers

Two things, and they answer different questions.

What is in it. The alkaloid profile, measured by weight. Our own reports list mitragynine, 7-hydroxymitragynine, paynantheine, speciogynine, speciociliatine, and a total. Other laboratories run a different panel, and some split the results across two tables, a high level one for the alkaloids present in quantity and a low level one for the traces.

Here’s the part most vendors skip. The industry spent years treating mitragynine percentage as the only quality score. As though a higher number on that one alkaloid decided whether a product was any good.

We now know kratom contains far more than that. More than forty alkaloids have been identified in the leaf. The DEA’s own figure is at least fifty-four. Any report you see anywhere covers a small handful of them. That’s worth knowing before anyone points at a number and tells you what it means.

The reason so little is known is not scientific difficulty. It’s that the research has never been funded. A drug company will spend nine figures on a molecule when there is a patent at the end of it. There is no patent on a leaf. So kratom sits in a gap: too marginal for serious money, too politically radioactive for casual study.

So a lab report tells you what is in a batch, measured against the compounds these panels cover. It does not tell you what the product will do. A vendor pointing at a mitragynine number as proof that a product is right for you is selling you a number that does not mean what they imply it means.

What is not in it, which is the other half of the job. The report also screens for things that should not be there at all, and those results should come back clean.

Elemental impurities. Arsenic, cadmium, mercury, and lead, each measured against a maximum limit. Kratom is grown in soil, and soil is where heavy metals come from.

Microbial contamination. Total aerobic plate count, yeast and mold, coliforms, E. coli, and Salmonella. This is the panel that matters most for a plant that is dried, milled, bagged, and shipped across an ocean. E. coli and Salmonella have to come back not detected, not merely low.

A report showing only alkaloid percentages is doing half the job.

A leaf report and an extract report do not read alike

They’re the same document with the same column headings, and that’s exactly why people misread them.

Leaf carries its alkaloids in the low milligrams per gram. An extract is leaf with the bulk taken out, so it carries the same alkaloids many times higher. A number that looks ordinary on one report looks wrong on the other, in both directions. Kratom Extract covers how that concentration happens.

There’s a second thing an extract report shows that a leaf report cannot, and it’s the most useful check on the page. An extract of leaf should read like leaf, only concentrated. The same alkaloids, in roughly the same proportions. Mitragynine largest, the others underneath it in the order the leaf puts them in. When a report shows that, the product is what the word extract says it is.

When a report shows mitragynine and almost nothing else, the other compounds were taken out on purpose. That is a purified extract, and a package saying high purity is describing exactly that. Both are honest products. They’re not the same product, and the certificate is the only place a customer can tell them apart.

That check is the reason we publish the whole report rather than a headline figure. The five formats and what each one does to the numbers are at Kratom Forms.

How to read one

Check six things.

The batch number, printed on your package, which should match the report exactly. Some labs call it a lot number instead. Same number, different word, and the two are used interchangeably across this industry.

The dates. Ours show when the sample was received, when testing completed, and when the report issued. Three dates are harder to fake than one. A report describes the lot it names and nothing else, so a report for a lot you aren’t holding is worth asking about.

The lab. Our house reports come from Cora Science, an independent laboratory in Austin, Texas, accredited to ISO/IEC 17025:2017. The brands we carry use their own accredited laboratories and those reports name them. That accreditation is the thing to look for. It means an outside body has verified the lab’s methods, not just that the lab exists.

The units, and this is the one that catches people. Laboratories report in milligrams per gram, in percent by weight, per serving, per unit and per package. Not every report carries all of them. Worse, a laboratory’s serving and a package’s serving are often different amounts. Both documents use the word serving anyway. Compare the two straight across and you can decide a label is inflated many times over when it is accurate. Read what the serving column is counting before you compare anything to the panel on the back.

The contaminant column, where you want PASS on every line, and Not Detected on E. coli and Salmonella.

Whether the report is complete. Cora Science’s terms state the report may not be reproduced except in its entirety. The other laboratories on this page carry the same restriction. A vendor showing you a cropped screenshot of one section has violated the lab’s terms and hidden the rest.

Then call the lab. Ours is reachable at the number printed on every report. Give them the report ID and ask whether it matches their records. Reports get edited. Dates change, numbers change, and some vendors publish reports that were never theirs to begin with. A lab will confirm its own document in about ninety seconds, and a vendor who objects to you checking has told you what you needed to know.

Why this matters more here than elsewhere

Where a state has passed a Kratom Consumer Protection Act, testing and labeling are required by law. Most states have not passed one. Across most of the country there is no agency verifying what is in a bag of kratom, no mandated testing, and no inspection regime.

No federal rule sets one either. Nothing says how a kratom product has to be tested, what has to appear on the label, or what is allowed in the package. That is why two products in the same category can present themselves completely differently and both be within the rules. Is Kratom Legal Federally? carries the full record.

Which means for a large share of this market, the lab report is voluntary. It’s the difference between brands that test and publish and brands that don’t, and there’s nothing forcing anyone into the first group.

That’s why our house product is tested three separate times by three separate parties. The farmer in Indonesia mills the leaf, has it tested, and ships it. The GMP qualified facility that packages it has it tested again on arrival, before anything goes into our bags. It ships to us, and we have it tested a third time before it goes up for sale. Every one of those goes to an independent lab. Nobody in that chain tests their own work.

One test tells you about one moment. Three tell you the material stayed clean the whole way.
