Kratom (Mitragyna speciosa) was once listed as a prohibited substance under the Narcotics Act. Kratom was then removed from the narcotics list in 2021 and is now regulated under the Kratom Plant Act B.E. 2565 (2022), which allows the trading, use, import, and export of kratom.

Food supplement specification and standards: Food supplements containing powdered kratom leaves or kratom leaf extracts must not have a dosage of over 0.2 mg/day of mitragynine (including 7-hydroxymitraglynine, which may occur naturally), or 1 mg/day for food supplements containing kratom extracts that use water as a solvent.

Additionally, the food supplement product must be in a ready-to-eat form (e.g., liquid, gel, tablet, or capsule).
