Third-party testing is laboratory analysis performed by an independent lab that has no ownership stake in the product being tested. Independence is what gives the results credibility, since the lab has no incentive in the outcome.
For kratom, third-party panels typically cover alkaloid content, heavy metals, and microbial contaminants, and the findings are summarized on a Certificate of Analysis. See COA and Lab Testing.
