EFSA Health Claims: What UK Supplement Brands Can and Cannot Say

Health claims are the minefield of the supplement industry. Say the wrong thing on your label, website, or Amazon listing and you are looking at anything from a listing suppression to a regulatory investigation. The rules are clear once you understand them. The problem is that most brands do not.

If you sell supplements in the UK or EU, your health claims are governed by EFSA. The European Food Safety Authority assessed thousands of claims and approved a specific list. Post-Brexit, the UK retained these regulations. The approved claims list is the same one you need to follow.

The Basics of EFSA Claims

EFSA health claims fall into two main categories under the original regulation.

Article 13 Claims (General Function Claims)

These are claims about the role of a nutrient in growth, development, and normal body functions. They are based on generally accepted scientific evidence. Examples include "Vitamin C contributes to the normal function of the immune system" and "Magnesium contributes to the reduction of tiredness and fatigue."

There is a specific approved wording for each claim. You can adapt the language slightly, but the meaning must remain the same. You cannot say "Vitamin C boosts your immune system" because "boosts" implies a performance enhancement beyond normal function. "Contributes to the normal function of" is the approved phrasing.

Article 14 Claims (Reduction of Disease Risk and Development Claims)

These are harder to get approved and require a much higher standard of evidence. Most supplement brands will primarily use Article 13 claims. Article 14 claims are rare and typically involve very well-established nutrient-disease relationships.

Common Mistakes Brands Make

After 16 years in supplement manufacturing, I have seen the same errors repeatedly. Some are innocent. Some are brands pushing boundaries hoping nobody notices. Both carry risk.

• •Using unapproved wording: Saying "supports immunity" instead of "contributes to the normal function of the immune system." Close is not compliant.
• •Making implied claims: Using images, testimonials, or product names that imply a health benefit without using approved claim wording. A product called "Sleep Formula" with a picture of someone sleeping peacefully is making an implied claim.
• •Claiming benefits for ingredients without approved claims: Just because an ingredient is trendy does not mean it has an EFSA-approved claim. Ashwagandha, for example, has no approved EFSA health claim. You cannot make health claims about it in the UK or EU market.
• •Missing conditions of use: Each approved claim has conditions. Minimum dosage per daily serving. Sometimes specific forms of the nutrient. If your product does not meet the conditions of use, you cannot make the claim.
• •Referencing studies instead of approved claims: Saying "Studies show that..." does not make a claim compliant. The claim itself must be from the approved list, regardless of what studies exist.

Why Amazon Cares More Than You Think

Amazon has become increasingly aggressive about supplement compliance. Their automated systems scan listings for non-compliant claims. If your listing contains unapproved health claims, it can be suppressed without warning. Getting it reinstated is a painful process involving appeals, documentation, and sometimes weeks of lost sales.

Worse, Amazon can flag your entire account if multiple listings have compliance issues. For a supplement brand that generates a significant portion of revenue through Amazon, this is an existential risk.

The same applies to paid advertising. Meta and Google both have policies on health claims in ads. Non-compliant ad copy gets rejected. Repeated violations can restrict your ad account.

How AI Can Help with Compliance

This is one of the most practical applications of AI for supplement brands. A compliance checker can scan your product copy, whether it is a label, website page, Amazon listing, or ad creative, and flag any claims that are not on the EFSA approved list.

It works by comparing the claims in your text against the official EFSA register. It checks the ingredient, the specific claim wording, and the conditions of use. It flags anything that does not match.

• •Scan a new product label before it goes to print
• •Check Amazon listing copy before publishing
• •Review ad copy before submitting to Meta or Google
• •Audit your entire product range for compliance gaps
• •Flag ingredients that have no approved claims at all

This does not replace regulatory expertise. You should still have a regulatory consultant review critical materials. But it catches the obvious errors before they reach that stage, saving time and reducing risk.

Practical Steps for Your Brand

First, get familiar with the approved claims list. The EFSA register is publicly available. Search by nutrient to see what you can and cannot say. Second, audit your current materials. Check every label, listing, and landing page against the approved claims. Third, build compliance into your workflow. Do not wait until a listing gets suppressed. Check claims at the copywriting stage, not after publishing.

If you are launching new products regularly, a compliance checking tool pays for itself on the first use. One avoided listing suppression or one prevented ad rejection saves more than the cost of implementation.

The rules are not complicated. They just require attention. And attention is exactly what automated systems are good at.
