Supplement Quality Seals: What "FDA-Registered" and "GMP" Really Mean
FDA-registered
Food and supplement facilities must register with the FDA; see FDA registration of food facilities. Registration is an inventory, not an endorsement of any product.
Made in the USA
Describes where manufacturing occurred. It says nothing about ingredient potency or purity on its own.
GMP (current good manufacturing practice)
Supplement makers must follow 21 CFR Part 111, which requires controls for identity, purity, strength and composition. Compliance is checked by FDA inspection, but a seal alone does not prove a specific batch.
Third-party testing
Independent labs can verify that a batch contains what the label says and lacks contaminants. Look for certificate-of-analysis documents from a named lab.
