EU EFSA Health Claims: How Chinese Supplement Factories Can Avoid Costly Pitfalls

If you manufacture dietary supplements in China and sell them in the European Union, you enter a regulatory environment that is arguably the strictest in the world for health-related marketing. The European Food Safety Authority (EFSA) evaluates every health claim used on food and supplement products, and only claims that survive rigorous scientific review make it onto the EU Register of Nutrition and Health Claims.

For Chinese OEM/ODM factories and the brands they serve, misunderstanding these rules can lead to seized shipments, forced relabeling, market withdrawals, and damaged buyer relationships. This guide walks you through the key pitfalls and how to avoid them.

1. Understand the Two-Step Gate: EFSA + National Enforcement

Many factories assume that if a claim “sounds scientific,” it is acceptable. In the EU, it is not. The process works in two steps:

• EFSA scientific evaluation: EFSA’s Panel on Dietetic Products, Nutrition and Allergies (NDA) reviews the scientific evidence supporting a claimed health relationship. Only if the evidence is deemed sufficient does EFSA issue a positive opinion.
• European Commission authorization: Even after a positive EFSA opinion, the claim must be formally authorized by the Commission and added to the EU Register before it can be used commercially.

Pitfall: Using a claim that EFSA evaluated positively but that was not yet authorized in the Register. This is still non-compliant.

2. Know Which Claims Are Already Authorized

The EU Register currently contains over 250 authorized health claims, most of which are “general function” Article 13 claims. These cover well-established relationships such as:

• Vitamin C contributes to the normal function of the immune system
• Calcium is needed for the maintenance of normal bones
• Omega-3 fatty acids (DHA) contributes to maintenance of normal brain function
• Magnesium contributes to a reduction of tiredness and fatigue

Pitfall: Paraphrasing authorized claims. The wording in the Register is fixed. You may simplify it for consumer understanding, but the meaning must not differ from the authorized version. For example, “Vitamin C boosts immunity” is not the same as the authorized claim and can be rejected.

3. Avoid the “Structure-Function” Trap

Unlike the United States, where the FDA permits structure-function claims under DSHEA without pre-market approval, the EU does not allow unapproved health claims simply because they describe a structural or functional effect. Every health claim — whether it references a nutrient’s role in body structure, function, or disease-risk reduction — must be authorized in the EU Register.

Pitfall: Brands that reformulate their US labeling for the EU market without removing structure-function claims that are not in the EU Register. Phrases like “supports joint health” or “promotes healthy digestion” are commonly used in the US but have no authorized EU equivalents and will trigger enforcement.

4. Be Careful with “Source of” and “High in” Claims

Nutrition claims (as opposed to health claims) are governed by Regulation (EC) No 1924/2006. Claims such as “source of [vitamin/mineral]” or “high in [nutrient]” have specific thresholds:

• “Source of”: The product must contain at least a significant amount as defined in Annex XIII of Regulation (EU) No 1169/2011 — generally at least 15% of the Nutrient Reference Value (NRV) per 100g or per 100ml, or per portion.
• “High in”: At least twice the “source of” value — typically 30% of NRV per 100g/100ml or per portion.

Pitfall: Printing “High in Vitamin C” on a gummy that contains only 20% NRV per serving. The claim is false, and the product is mislabeled. Always verify actual nutrient content against claim thresholds before approving artwork.

5. Probiotic Claims: The Notorious Rejections

EFSA has rejected hundreds of probiotic health claim applications, including claims about gut health, immune support, and digestion for specific strains. As of now, there are no authorized probiotic health claims in the EU Register for the term “probiotic” itself, and very few strain-specific claims have survived.

Pitfall: Marketing probiotic supplements in the EU with claims like “improves gut flora” or “supports digestive health.” These are unauthorized health claims. Brands must rely on authorized nutrient claims (if the product contains added vitamins/minerals) or sell without health claims entirely.

Practical advice for factories: When manufacturing probiotic products for EU-bound brands, make sure your buyer is aware of this restriction. Do not print health claims on labels or marketing materials unless they are explicitly authorized. The product can still be sold — it just cannot carry probiotic-specific health claims.

6. Country-Specific Enforcement Matters

While EFSA sets the scientific bar, enforcement is national. Each EU member state has its own food safety authority that monitors the market. Some countries are more aggressive than others:

• Germany (BVL): Known for strict enforcement and rapid action on non-compliant claims.
• UK (FSA, post-Brexit): The UK now maintains its own list of authorized claims, largely mirroring the EU Register but diverging over time. Check both lists if selling to the UK.
• Netherlands (NVWA): Active enforcement, especially on online sales platforms.
• Italy (Ministero della Salute): Requires notification of food supplements before market placement — an additional step beyond EU-wide rules.

Pitfall: Assuming EU-wide compliance means country-level compliance. Italy’s notification requirement, for example, is a national law that applies in addition to EFSA rules. If your buyer ships to Italy without completing the notification, the product can be blocked at customs.

7. What Chinese Factories Should Do Differently

As an OEM/ODM partner, your role is not just manufacturing — it is also risk prevention. Here are concrete steps:

1. Maintain a current copy of the EU Register of Nutrition and Health Claims and cross-reference every label before production.
2. Educate your buyers about EFSA restrictions, especially for probiotic and botanical products where most claims are not authorized.
3. Offer compliant label design services or partner with regulatory consultants who can verify label compliance for the target EU market.
4. Track nutrient content precisely in your QA process so that “source of” and “high in” claims can be validated against actual analytical results.
5. Flag country-specific requirements (Italian notification, Belgian notification for certain categories, etc.) to your buyers before shipping.
6. Keep stability data on file — if a claim depends on nutrient levels at end of shelf life, you need data proving the claim holds throughout the product’s stated expiry.

8. Botanical Claims: A Special Complication

The EU has a transitional measure for “botanical” health claims (claims on plant-based substances used in traditional medicines). These claims were put “on hold” — they can still be used in some member states while EFSA completes its evaluation, but the situation is legally uncertain and varies by country.

Pitfall: Assuming “on hold” means “safe to use everywhere.” Some countries interpret the hold differently. In Germany, many botanical claims have been removed from products. In France, a traditional use register provides a separate pathway. Always check the specific country’s position on botanical claims before printing them.

Conclusion

Navigating EU EFSA health claims is not about memorizing a list — it is about building a compliance mindset into your manufacturing and labeling workflow. Chinese OEM/ODM factories that proactively understand these rules become more valuable partners to brands targeting the European market. By flagging risks early, maintaining accurate nutrient data, and educating your buyers, you reduce the chance of costly recalls and strengthen your reputation as a reliable, regulation-aware manufacturer.
