Frontiers perspective calls for clearer definitions across kratom product categories

Why it matters

The paper argues that regulators, manufacturers and consumers need clearer terminology to distinguish traditional leaf products from high-concentration or synthetic products sold under similar labels. Shared definitions could make labeling and policy discussions more precise.

The big picture

Kratom products now span a wide range of formulations and alkaloid concentrations. The authors frame the issue as one of classification and communication, rather than a clinical effectiveness finding, as policymakers respond to an evolving market.

Key findings

• The authors describe a U.S. market that includes products with varying kratom alkaloid concentrations.
• They note that some products labeled as kratom contain highly concentrated synthetic alkaloids.
• The perspective calls for distinct terms for kratom, kratom-derived and synthetic products.
• It presents terminology standardization as a tool for clearer manufacturing and labeling practices.
• The proposed reference is intended for industry and federal, state and local jurisdictions.

What they say

The authors write that consumers and regulators “struggle to differentiate” products resembling traditional kratom from products containing highly concentrated synthetic alkaloids.

Bottom line

Clear product definitions are a policy and labeling foundation, but this perspective does not itself establish the safety or effects of any product category.
