EFSA health claim substantiation consumer study

EFSA Health Claim Types: A Practical Guide for Supplement Brands

If your supplement or wellness product is sold in Germany or elsewhere in the EU, the health claims you can legally make aren't a matter of what you can substantiate on your own - they're governed by a specific, closed system run through EFSA (the European Food Safety Authority) and the EU Nutrition and Health Claims Regulation (NHCR, EC 1924/2006). This is a fundamentally different model from the US, where the FTC evaluates claim-by-claim evidence. In the EU, claims largely have to come from an approved list.

Understanding which type of claim you're making - and what's actually available to you - is the first step in any EU claims strategy, and it's a step many brands (especially those expanding from a US-first playbook) get wrong.

The three claim categories that matter

Article 13.1 claims are the general, pre-approved claims based on generally accepted scientific evidence. Things like "calcium contributes to normal bone structure" or "vitamin C contributes to normal immune function." These are published on the EU Register of nutrition and health claims. If your product genuinely contains the relevant nutrient at an authorized level, you can use the exact, pre-approved wording. You cannot paraphrase it into something punchier; the wording itself is regulated.

Article 13.5 claims cover claims based on newly developed scientific evidence, including proprietary research. This is the pathway relevant to branded, novel ingredients (like Metabolaid® or similar proprietary blends) where the health effect isn't already on the generic Article 13.1 list. These require a formal application to EFSA with a full dossier of supporting evidence; a materially heavier lift than 13.1, and one where the quality and design of your underlying research (including consumer perception data as supporting, contextual evidence) matters.

Article 14 claims cover reduction of disease risk claims and claims referring to children's development and health. These carry the highest evidentiary bar and the most rigorous EFSA review process, and are generally out of reach for early-stage or mid-size supplement brands without dedicated regulatory resources.

Where this leaves most supplement brands

Most consumer supplement brands operate in one of two realistic lanes:

1. Using existing Article 13.1 claims correctly - verifying your formulation actually meets the authorized nutrient thresholds, and using the exact approved wording rather than a marketing-friendly rewrite.

2. Building a case for a novel or branded-ingredient claim (Article 13.5) - where a well-designed consumer study, alongside any existing ingredient research, becomes part of the evidence base supporting a future submission, or informs how you talk about the product in ways that stay on the right side of "general wellness" language rather than a formal, unauthorized health claim.

This second lane is where a lot of ambiguity — and a lot of risk — lives. Brands often default to vague, non-specific "wellness" language specifically because pursuing a formal Article 13.5 claim feels out of reach. That's a reasonable instinct, but it also means leaving a stronger, more differentiated marketing position on the table if the underlying evidence could support it.

What consumer research can and can't do here

A structured consumer perception study is not, on its own, sufficient to secure a new authorized EFSA health claim - that requires the formal Article 13.5 or 14 submission process, generally alongside more mechanistic or clinical evidence. What a consumer study can do is:

- Provide supporting, real-world evidence of perceived effect that strengthens a broader evidence dossier.

- Generate honest, defensible language for general wellness marketing that stays within the "no unauthorized health claim" boundary while still saying something specific and credible.

- Surface which effects consumers actually notice and value, which is directly useful input for deciding which formal claim (if any) is worth pursuing.

For brands weighing whether to invest in the formal EFSA submission route versus building a defensible general-wellness marketing position in the meantime, How to Substantiate a Supplement Claim Without a Clinical Trial covers the broader evidence-and-claims framework, and EU vs. US Supplement Validation Requirements lays out how the two systems differ if you're marketing across both regions.
