What Is FTC Substantiation Doctrine?

Why It Matters for Supplement Brands

While FDA regulates label claims, FTC regulates advertising claims — including website copy, social media, email marketing, and influencer content. FTC's standard is often more demanding than FDA's, and FTC has been increasingly active in enforcement against supplement companies, with penalties reaching tens of millions of dollars.

How It Works

FTC's 'competent and reliable scientific evidence' standard typically means:

1. **Controlled clinical studies** on the specific product or a substantially similar product 2. **Human studies** (not just animal or in vitro) 3. **Published or peer-reviewed** research 4. **Relevant to the claims made** — the studies must test the specific benefit claimed 5. **Sound methodology** — adequate sample size, proper controls, valid metrics

FTC looks at the **totality of the evidence**, not just individual studies. This includes: - Number and quality of supporting studies - Whether the evidence is consistent across multiple studies - Whether the study design matches the claim being made - Whether there are contradicting studies

Key FTC enforcement triggers: - Before/after photos without documenting typical results - Using the word 'clinically proven' or 'scientifically proven' - Endorsements without adequate disclosure - Health claims that go beyond the evidence

Common Mistakes to Avoid

• ✗Having substantiation for label claims but not for broader advertising claims (website, social media)
• ✗Using superlative language ('clinically proven,' '#1 recommended') without supporting evidence
• ✗Not substantiating claims made by influencers or affiliates on the brand's behalf
