How to Read a Kratom Lab Report (COA)
Updated Oct 20, 2026
What a COA is
An independent lab's report for one batch. It should name the lab, the batch number and the test date.
Sections to read
Alkaloid profile (mitragynine %, and 7-OH, which should be trace in natural leaf). Heavy metals (lead, arsenic, cadmium, mercury). Microbials (salmonella, E. coli, yeast/mold).
Red flags
No batch match, no lab name, a COA older than 12 months, or 7-OH levels far above natural leaf.
