How to Read a Kratom Certificate of Analysis (COA)

A Certificate of Analysis, or COA, is laboratory documentation associated with a product or batch. It can provide customers with additional information about testing performed by a third-party laboratory.

What to Look For

  • Product or batch identification: Check that the report corresponds to the product or lot you are reviewing.
  • Laboratory information: Look for the name of the laboratory and report date.
  • Testing categories: Depending on the report, these may include heavy metals, microbial testing or other product-specific results.
  • Result units and limits: Review the units and any stated laboratory reference limits carefully.
