Supplement 101
What Certifications Mean
Supplement certifications verify specific aspects such as manufacturing, purity, or labeling, but do not determine overall product quality.
Certifications answer specific questions.
They do not answer whether a product is good.
Different certifications operate at different layers:
- cGMP — whether the product is manufactured consistently
- USP / NSF — whether contents match defined standards
- IFOS — whether specific products meet purity and freshness benchmarks
Each of these introduces a form of control or verification.
None of them evaluate formulation intent, dose relevance, or overall design.
A product can be certified across multiple standards and still lack coherence.
Certifications reduce uncertainty.
They do not define value.
