How to read a Certificate of Analysis

  1. Match the product and lot number to your bottle.
  2. Check the testing or approval date and the stated expiration date.
  3. Review each test, its method, specification, and result.
  4. Distinguish measured test results from amounts calculated from raw-material input or batch records.
  5. Check whether the report includes the contaminants or identity tests relevant to your question.

A report does not establish clinical effectiveness or FDA approval. An older report does not automatically represent a current batch.
