Lab Study Finds "Kratom Extract" Products Are Synthetically Altered, Not Botanical Kratom

Why it matters

Consumers and regulators have struggled to distinguish traditional kratom leaf from highly concentrated 7-OH products sold under the "kratom extract" label. This peer-reviewed study provides chemical proof that marketed 7-OH products are synthetic derivatives, not botanical kratom — a distinction critical for appropriate regulation and consumer safety.

The big picture

As kratom use grew in the United States over the past decade, a new category of products emerged: concentrated forms of 7-hydroxymitragynine (7-HMG) sold as "kratom extracts." Unlike traditional kratom leaf consumed for centuries in Southeast Asia, these products contain unusually high 7-HMG levels only achievable through chemical synthesis. The study's findings directly supported subsequent FDA and DEA actions in 2026 to restrict concentrated 7-OH products while leaving botanical kratom in a separate regulatory category.

Key findings

• 7-HMG concentrations in tested products ranged from 22 to 75 mg/g dry weight — 5 to 28 percent above what labels claimed
• Mitragynine levels were 2.0 to 6.0 mg/g, substantially lower than what is found in authentic kratom leaf or botanical extracts
• Chromatographic profiles of all tested products were inconsistent with genuine kratom leaf
• Products lacked the full spectrum of naturally occurring kratom alkaloids
• Concentrations of 7-HMG found are only achievable through synthetic production, not natural plant processing
• Researchers concluded the products are "unapproved new drugs being unlawfully marketed" under kratom labeling

What they say

The authors concluded: "There is an urgent need to differentiate kratom, which has been safely consumed for centuries, from 7-hydroxymitragynine, which may pose a significant risk to public health."

Bottom line

Chemical analysis proves that products sold as "kratom extracts" are synthetically produced 7-OH compounds — not botanical kratom — making their labeling unlawful and their regulatory treatment distinct from traditional kratom leaf.
