Clinical takeaways
- 21 CFR 111 requires specifications and verification for identity, purity, strength and composition.
- FDA inspects facilities but does not approve supplements before sale.
- USP 2232 sets daily limits for lead, arsenic, cadmium and mercury.
- Only published lot results or independent seals let buyers verify any of it.
The cGMP rule in one paragraph
Since 2007-2010, every company that makes, packages, labels or holds dietary supplements for the U.S. market must comply with 21 CFR Part 111.[1] It requires written specifications for each component and finished batch, identity testing of every dietary ingredient, batch production records, quality-unit review, and handling of complaints and returns. It is a process standard: it says how to make a product consistently, not what results must be published.
What an audit looks at
- Supplier qualification and identity testing of incoming botanicals
- Master manufacturing record and batch records for each lot
- Equipment cleaning and calibration
- Release testing against the specification
- Reserve samples and complaint files
FDA inspections are risk-based and infrequent; private audits by NSF or similar bodies supplement them. FDA reminds consumers that it does not approve supplements for safety or effectiveness before they are sold.[2]
Heavy metals and USP 2232
USP general chapter 2232 sets permitted daily exposures for elemental impurities in supplements, with lead, arsenic, cadmium and mercury the main concerns. Botanicals pick these up from soil, so blends with many plant extracts warrant testing. A certificate of analysis should show results for each metal against the limit.
Hepatotoxicity reviews
Quality is not only contamination. USP's 2020 safety review of green tea extracts recommended label warnings about rare liver injury, especially with concentrated extracts taken fasting.[3]
Applying it to Payarmin
The label names a distributor but not the facility, and no certificate of analysis, heavy-metal result or third-party seal is published. That does not mean the product fails any of these; it means you cannot confirm it from outside. Ask support for your lot's certificate, as described on our quality standards page.
