Health claims: what a brand is allowed to say

Have you noticed that every magnesium supplement in Europe says exactly the same sentence, "contributes to a reduction of tiredness and fatigue"? That is not laziness. It is the law. Since 2006, a brand may only make health claims that sit on a European list, in wording that is essentially fixed. Here is how that list came to be, why it explains the sameness of the market, what falls outside it, and the lines BIORYA has chosen not to cross.

← Back to the Observatory

Regulation (EC) No 1924/2006 set a simple principle: any statement that links a food or ingredient to health must have been evaluated by the European Food Safety Authority (EFSA) and authorised by the European Commission. Everything else is forbidden. The result is a public EU Register of a few hundred authorised health claims, each attached to a nutrient, a condition of use and an approved wording. For food supplements, this register is the entire vocabulary a brand is allowed to use about health. Not a word more.

Brussels, 2006: the regulation that decided which sentences may appear on a supplement box.

1. The rules in a few markers

The textRegulation (EC) 1924/2006 on nutrition and health claims
Nutrition claimDescribes what the product contains: "source of magnesium", "high in vitamin B6"
Health claimLinks a nutrient to a body function: "magnesium contributes to normal muscle function"
Who decidesEFSA evaluates the science; the European Commission authorises
Strictly forbiddenAny reference to preventing, treating or curing a disease
Also forbiddenClaims that a balanced diet cannot provide adequate nutrients, references to doctors' recommendations, or to the rate or amount of weight loss
Who checksIn France, the DGCCRF; sanctions range from withdrawal to criminal fines for misleading practices
Where it appliesLabel, website, social media, influencer content: every commercial communication

2. How a sentence gets onto the list

Step 1 · 44,000 proposals

After 2006, Member States collected the claims companies wanted to keep using: some 44,000 entries, consolidated by EFSA into about 4,600 to evaluate. The task took five years.

Step 2 · One question

For each claim, EFSA asked whether a cause-and-effect relationship between the substance and the effect was established by generally accepted scientific evidence. Not "is there a signal", but "is it demonstrated". Most claims failed that test.

Step 3 · The 2012 list

Regulation 432/2012 published the first authorised list: 222 claims, almost all about vitamins, minerals and a handful of well-studied substances. It has grown a little since, to around 260. More than 2,000 claims were rejected.

Step 4 · Plants left "on hold"

Botanicals were a special case: EFSA rejected traditional use as evidence, Member States disagreed, and the Commission suspended their evaluation. More than 2,000 plant claims have been "on hold" since 2010, usable under national rules and the operator's responsibility, but never formally authorised.

3. Four numbers behind the sameness

~260health claims authorised in the EU Register today, for the whole of the European food and supplement market
2 000+claims rejected by EFSA for lack of established cause-and-effect, and about as many botanical claims still "on hold"
10authorised claims for magnesium, and 10 for vitamin B6: the only two nutrients in the CALM AUTHORITY formula listed in the register. At our dose, only B6 crosses the "significant amount" threshold
0authorised health claims for saffron, L-theanine or rhodiola. Their science exists; it lives in studies, not in permitted marketing sentences

4. Why every brand says the same thing

Because the sentence is not theirs. When a brand writes "magnesium contributes to normal psychological function", it is quoting the register almost word for word. Some flexibility of wording is tolerated, provided the meaning for the consumer stays identical: "helps support" may replace "contributes to", but "boosts", "restores" or "fights" go beyond the authorised effect and are refused. The claim must also concern the nutrient, never the product as a whole: a brand may say what magnesium does, not that its box "reduces your stress". And the product must contain a significant amount, at least 15 % of the reference value per daily portion, or the sentence may not be used at all.

NutrientAuthorised wording (extract)On CALM AUTHORITY?
Vitamin B6Contributes to normal psychological function · to normal functioning of the nervous system · to the reduction of tiredness and fatigue · to the regulation of hormonal activity · to normal energy-yielding metabolismYes: 2.55 mg per portion, 182 % NRV
MagnesiumContributes to a reduction of tiredness and fatigue · to normal psychological function · to normal functioning of the nervous system · to normal muscle function · to electrolyte balanceNot entitled to: 40 mg is 10.7 % NRV, below the 15 % "significant amount" threshold. Our magnesium is a supporting intake, not a claim carrier
Saffron, L-theanine, rhodiolaNone authorised. Botanical claims "on hold" may be used under national rules and the operator's responsibilityWe describe their science in the Observatory as educational content, kept apart from the product pitch

5. True or false: what you read online

The claimVerdictThe nuance
"If it's written on the site, it's been proven"FalseAuthorised claims have been evaluated. Anything beyond them ("anti-stress", "restores serenity") has not, and is illegal even if widespread. Enforcement lags behind the market.
"Clinically proven means tested on this product"RarelyNine times out of ten the studies concern an ingredient, at a given dose, in a given population. Transferring them to the finished product is a leap the regulation does not allow.
"A customer review can say what the brand can't"FalseA testimonial selected and displayed by the brand is commercial communication. If it implies a medical effect, the brand is responsible for it.
"Traditionally used for" is an approved claimFalseIt is the wording of a claim "on hold": tolerated pending evaluation, not authorised. Honest brands say so.
"A supplement can be 'anti-anxiety'"NoAnxiety and depression are medical conditions. Claiming to act on them is a therapeutic claim, reserved for medicines. The only permitted territory is normal function: "psychological function", "nervous system".

Educational content about the regulatory framework, not legal advice. Each claim in the register carries specific conditions of use.

6. What BIORYA has chosen not to say

No medical vocabulary

You will not read "anti-anxiety", "antidepressant", "treats", "heals" or "replaces" about CALM AUTHORITY. Anxiety and depression are conditions that call for a professional, and our disclaimers say so on every page that touches the subject.

Studies stay with the ingredients

The trials we cite on saffron, L-theanine, rhodiola or magnesium concern those ingredients as raw materials. We say so explicitly, and we never present them as proof about the finished product or write "clinically proven" on the box.

A wall between the Observatory and the shop

The Observatory explains the science, with sources, as educational content. The product page states the composition and the authorised claims. The two are linked, but the first is never used as a sales argument dressed up as an article.

No borrowed authority

No white coats, no "recommended by doctors", no before-and-after, no promise of transformation. Reviews are published as written, and we do not use them as evidence of an effect. The claim on our box is the ritual itself: sixty seconds, every morning.

7. And day to day?

When you read a supplement page, look for the register's vocabulary: "contributes to", "normal function", a named nutrient. That is the sound of a brand staying within the rules. When you read "fights stress", "restores your calm", "clinically proven formula", you are reading a sentence nobody has evaluated. Neither is a guarantee of quality, but the first tells you the brand knows the law and chose to respect it. To go further, our article on reading a label in three lines shows where the real information sits, and the vitamin B6 and magnesium articles explain what lies behind the two claims we are allowed to make.
