Master the essential supplement verification process by approaching each product with a structured checklist. This guide outlines the supplement verification process and its three pillars: label accuracy, independent certifications, and third‑party test results. By following this approach, you build a foundation for safety, verify declared ingredient levels, and foster trust that relies on verifiable evidence rather than marketing language. Label checks: Start with the label itself. Compare the listed ingredients to the stated formula, confirm serving size and declared amounts, and note any “proprietary blend” entries without explicit quantities. Look for the manufacturer’s name, street address or contact information, country of origin, lot or batch numbers, and an expiration date. Please also check allergen statements and any potential cross‑contamination notes. Keeping a clear copy of the label supports the verification process when you compare sources later. Certifications: Then evaluate independent certifications. Credible marks such as USP Verified, NSF Certified for Sport, Non-GMO Project Verified, and similar programs indicate external review. Verify the product and company appear on the certifier’s official site and check that the certification is current. Be wary of logos without a verifiable certificate number or an accessible audit history. Certifications are a key part of building trust in the verification process. Third‑party testing and COAs: Finally, examine third‑party test results. A current Certificate of Analysis (COA) from an accredited laboratory should accompany the product or be available on request. Review the COA to confirm the identity of listed ingredients, the declared amounts, and the absence or presence of undeclared substances within stated limits. Note the test date, the testing methods, the laboratory name, and batch identifiers. Document your findings, store COAs securely, and use them to support an ongoing, rigorous approach to the supplement verification process.
