UK Supplement Compliance: What EFSA Health Claims Actually Mean for You

If you have ever read a supplement label and wondered why the wording sounds so careful — "contributes to," "supports the maintenance of," "in the context of" — there is a very specific reason. These phrases are not marketing choices. They are legally mandated.

In the United Kingdom and European Union, every health claim made on a food supplement must be drawn from an approved register maintained under Regulation (EC) No 1924/2006. The claims on this register were evaluated by the European Food Safety Authority (EFSA) based on the available scientific evidence. If a claim was deemed sufficiently supported, it was authorised. If not, it was rejected.

This regulation exists to protect you from misleading health claims. Understanding how it works gives you the tools to distinguish between products making legitimate, evidence-backed statements and those stretching the truth.

What Is a Health Claim?

Under the regulation, a health claim is any statement that suggests or implies a relationship between a food (or food component) and health. Examples include "Vitamin C contributes to the normal function of the immune system," "Calcium is needed for the maintenance of normal bones," and "Creatine increases physical performance in successive bursts of short-term, high-intensity exercise."

These are specific, carefully worded claims. They were drafted by scientific panels, debated by regulatory committees, and approved for use only when the evidence met defined standards.

A medicinal claim, by contrast, suggests that a product can treat, cure, prevent, or diagnose a disease. Medicinal claims are not permitted on food supplements in the UK — a product making such claims would need to be licensed as a medicine. This is why you will never see a compliant supplement say it "treats depression" or "cures joint pain."

How the Register Works

The EU Register of nutrition and health claims is a publicly searchable database. It lists every authorised claim, the nutrient or substance it applies to, the conditions of use (such as the minimum dose required), and the target population. Post-Brexit, the UK has retained this framework, meaning the same claims and standards continue to apply.

Each claim was evaluated through a rigorous process. A food business submitted a dossier of scientific evidence to EFSA. The EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA Panel) reviewed the evidence against defined criteria: the substance must be sufficiently characterised, the claimed effect must be a beneficial physiological effect, and a cause-and-effect relationship must be established between consumption of the substance and the claimed effect.

Claims that failed to meet these criteria were rejected. Many popular supplement ingredients — including turmeric, ashwagandha, probiotics (as a category), and collagen — currently do not hold authorised health claims. This does not necessarily mean they are ineffective, but it means the scientific evidence submitted to EFSA did not meet the Authority's standards at the time of evaluation.

What This Means for You as a Consumer

When a supplement displays an authorised health claim, you can be reasonably confident that the relationship described has been scientifically evaluated and approved by an independent regulatory body. You can also check whether the product delivers the ingredient at the dose required for the claim to apply.

For example, the authorised claim for glucomannan and weight loss specifies that the beneficial effect is obtained with a daily intake of 3 g in three doses of 1 g each, with 1–2 glasses of water, before meals, and in the context of an energy-restricted diet. If a product contains glucomannan but provides only 500 mg per day, it cannot lawfully make the weight loss claim because the conditions of use are not met.

Similarly, the claim that "creatine increases physical performance in successive bursts of short-term, high-intensity exercise" is authorised at a daily intake of 3 g. A product containing 1 g of creatine per serving would need to clearly state that 3 servings are required to meet the claim condition.

The "Grey Area" of Traditional-Use Ingredients

Many popular supplement ingredients fall into a category where traditional use is extensive but EFSA-authorised claims are absent. Ashwagandha, turmeric/curcumin, Lion's Mane mushroom, Rhodiola rosea, Milk Thistle, and many probiotic strains are used by millions of consumers and supported by a growing body of published research — but they do not currently have authorised claims on the EU/UK Register.

How should responsible brands handle this? Transparently. A brand should clearly state when an ingredient does not hold an authorised claim and should describe its inclusion based on traditional use, not implied clinical proof. The language "traditionally used in Ayurvedic practice" is different from "clinically proven to reduce stress." The former is a factual description of historical use; the latter implies a level of regulatory validation that does not yet exist for that ingredient.

At Veldic, we include traditional-use ingredients in several of our formulas because we believe the evidence base justifies their inclusion — but we never overstate what the science currently supports. Every product page clearly identifies which claims are EFSA-authorised and which are based on traditional use.

How to Evaluate Claims You See Online

Not every supplement brand is compliant. Social media, in particular, is rife with health claims that would not survive regulatory scrutiny. Influencer endorsements, before-and-after photos, and testimonial-based marketing often contain implied health claims that cross the legal boundary.

Here are practical steps to evaluate any supplement claim: check whether the specific claim appears on the EU/UK Register of health claims; verify whether the product contains the ingredient at the dose required for the claim; look for clear identification of traditional-use ingredients versus EFSA-authorised ingredients; check for MHRA compliance and GMP certification; and be wary of any product that implies it can treat a specific disease or medical condition.

Why Compliance Is a Feature, Not a Limitation

Some brands treat regulatory compliance as a constraint — something that limits their marketing. We take a different view. Compliance is a feature. It means every claim we make has been evaluated by independent scientists. It means our labels tell the truth about what our products contain and what they can do. It means you can compare our products against any competitor on the basis of evidence and transparency, not just branding and packaging.

The supplement industry does not always make this easy. But the tools are there for any consumer who knows where to look — and now you do.
