Is stability testing required by the FDA for supplements?

Yes. Under 21 CFR Part 111, dietary supplement manufacturers operating under cGMP are required to conduct stability testing to establish product expiration dating. Studies must cover potency, moisture content, and microbial limits at defined time points. Third-party tested labs provide the independent documentation needed for cGMP audits.
