In the competitive dietary supplement industry, working with a qualified Supplement Manufacturer requires meticulous attention to documentation. Among the most critical documents for ensuring product quality and regulatory compliance is the Certificate of Analysis (COA). This comprehensive quality assurance document serves as documented evidence that your supplement meets established specifications for identity, purity, strength, and composition.

What Is a Certificate of Analysis?
A Certificate of Analysis is a legally binding document that verifies a specific batch of dietary supplement has been tested and meets predetermined quality specifications. CoAs are part of the requirements to meet good manufacturing practices (GMP) as outlined by Title 21. This document provides transparency between suppliers, manufacturers, and regulatory bodies while ensuring consumer safety.
Key components of a COA include:
- Product identification including batch number and manufacturing date
- Test methodology used for each analysis
- Specification limits for each parameter tested
- Actual test results from the specific batch
- Authorization signatures from qualified personnel
- Testing date and expiration information
FDA Requirements for Certificate of Analysis
The FDA’s regulations under 21 CFR 111.75 establish specific requirements for using COAs in dietary supplement manufacturing. According to the regulations, manufacturers may rely on a supplier’s COA provided that:
• The manufacturer first qualifies the supplier by confirming test results • The certificate of analysis includes a description of the test or examination method(s) used, limits of the test or examinations, and actual results of the tests or examinations • Documentation is maintained showing how the supplier was qualified • The supplier’s COA is periodically reconfirmed • Quality control personnel review and approve all documentation
