Lab Tests Confirm Products Sold as "Kratom Extracts" Are Actually Synthetic 7-OH Drugs

Why it matters
Consumers buying products labeled as "kratom extracts" may unknowingly be ingesting high-dose synthetic opioids with unknown risks — and no clinical safety data. Mislabeled products may also be distorting adverse event data attributed to natural kratom.
The big picture
The distinction between traditional kratom leaf and synthetic 7-OH is central to the national policy debate. As regulators in dozens of states grapple with how to classify kratom, mislabeled synthetic products may be inflating the risk profile attributed to natural kratom — and the FDA has already asked the DEA to place synthetic 7-OH on Schedule I. This study from BC Institute of Technology provides the first laboratory confirmation that products sold as "kratom extracts" are chemically inconsistent with actual kratom leaf.
Key findings
- BC Institute of Technology researchers tested 5 brands of products labeled as "kratom extracts" for mitragynine and 7-OH using an official AOAC validated HPLC method
- All products had 7-OH as the dominant alkaloid at 22–75 mg/g — 5 to 28% higher than what the labels claimed
- Natural kratom leaf contains 7-OH only at trace levels (<0.004% w/w); achieving the product levels requires synthetic chemical conversion
- Products also contained unidentified chromatographic peaks not present in authentic kratom leaf
- Inconsistency within the same product brand — three packages of the same product varied significantly — indicates poor manufacturing controls
What they say
The researchers concluded that "the presence of concentrated 7-hydroxymitragynine products in the market masquerading as kratom is misleading, unlawful, and potentially dangerous to the public," and called urgently for regulatory action to remove these "unapproved, synthetic products" from commerce.
Bottom line
Products sold as "kratom extracts" are actually synthetic 7-OH drugs — and laboratory evidence confirms they are chemically, functionally, and biologically distinct from natural kratom leaf.
