What to know before you buy kratom
Kratom is the leaf of Mitragyna speciosa, a tropical tree native to Southeast Asia. It is sold as powder, capsules, crushed leaf, and extracts, and it contains the alkaloids mitragynine and 7-hydroxymitragynine. It is not an approved medicine and is not intended to diagnose, treat, cure, or prevent any disease.
The most useful way to choose is by vein color. Red vein is generally the most relaxed and evening-oriented, green is balanced, white is the most energetic, and yellow is smoother. Regional names — Maeng Da, Bali, Borneo, Malay, Thai — describe a growing area or processing style rather than a guaranteed effect.
Whatever you choose, batch matters more than the name. Kratom is an unregulated agricultural product, so potency and purity vary from bag to bag. Buy from vendors who publish third-party lab testing and can show a certificate of analysis (COA) for the exact batch you receive, and start with a small serving before committing.
Finally, kratom is for adults 21 and older, may be habit-forming, and is not appropriate during pregnancy or nursing. Availability depends on state and local law. Read our dosage and safety guides before you start.
