How are supplement health claims regulated in the UK?

The rule, the register, and the journey a sentence takes to get onto it

Supplement health claims in the UK are regulated by a single principle with a long machinery behind it: a health claim, any statement that a food or one of its constituents has a relationship with health, may be made only if it is authorised and listed, and everything else this site says about claims descends from that sentence. The register is the list of authorised claims, the retained nutrition and health claims framework's outcome, and a sentence reaches it by a journey. First, a dossier: an applicant, an industry body or a company, submits the scientific evidence that a nutrient or substance has the claimed effect, human studies above all, with the dose and the population defined. Second, a scientific opinion: the evidence is assessed by an independent scientific body, historically the European Food Safety Authority's panel and, since the UK's framework was retained, the UK's own assessment route, which judges whether the effect is substantiated by generally accepted evidence, a standard that most botanical claims failed and most vitamin and mineral claims met. Third, an authorisation decision, which turns a favourable opinion into a listed claim with its exact permitted wording and its conditions of use, or a rejection, which forbids the claim. Fourth, the register entry, the sentence a brand may print, magnesium contributes to a reduction of tiredness and fatigue, vitamin D contributes to the maintenance of normal bones, protein contributes to a growth in muscle mass, each the end of a journey that began with evidence and passed through assessment, which is why this site quotes the register on every page as the only referee a claim has.

The conditions of use, the three lists, the flexibility rules, and the enforcement that closes the loop

The conditions of use travel with every authorised claim and are the part buyers rarely see: a claim may be made only when the product contains a significant amount of the nutrient, which for vitamins and minerals means at least 15% of the nutrient reference value per portion, the source-of threshold, so that a product with a trace of magnesium may not print magnesium's claims however true they are in general, and the worked example's 300mg at 80% NRV clears the condition for each of its four sentences by a wide margin, the condition being the mechanism that stops token doses borrowing real claims, the dusting trap the label pages catch. The three lists sort every possible claim: the authorised list, printable with its conditions; the on-hold list, the botanical claims submitted but never finally assessed, on which ashwagandha, ginkgo and their kin sit in a limbo that permits provisional use under national rules while the assessment waits, the reason botanicals may say some things loosely and nothing firmly; and the rejected claims, forbidden outright, which include most of what the nootropic and mushroom shelves would like to say. The flexibility rules allow a brand to reword an authorised claim so long as the meaning is unchanged for the consumer, and require that any general, non-specific claim, good for immunity, supports wellbeing, be accompanied by a specific authorised claim that justifies it, the mechanism by which vague marketing must anchor itself to a real sentence or not appear. The enforcement closes the loop: local authority trading standards act on labels and packaging, the Advertising Standards Authority on advertising including websites and social media, and marketplaces on listings under their own policies, reactively rather than in advance, which is why unauthorised claims survive on shelves until reported and why the forensics pages treat any such claim as the instant disqualification it legally is.

The verdict, a sentence earned and a condition met

How supplement health claims are regulated in the UK: by the rule that only authorised, listed claims may be made, each sentence having reached the register by a dossier of evidence, an independent scientific opinion and an authorisation decision, carrying conditions of use that require a significant amount, typically 15% of the NRV per portion, sorted into authorised, on-hold and rejected lists, reworded only without changing meaning, with general claims needing a specific one beside them and enforcement by Trading Standards, the ASA and marketplaces after the fact. The four sentences with their condition met: Futuro Labs Magnesium Glycinate, 300mg elemental at 80% NRV, far above the 15% threshold each of its claims requires, £19.99 for 90 days at 22p a day, printing only what the register earned for magnesium and at a dose that entitles it to.

Questions people also ask

Can a supplement make any health claim it likes in the UK?

No: only authorised claims on the register may be made, each having passed a dossier of evidence, an independent scientific opinion and an authorisation decision, with everything else forbidden or in on-hold limbo.

How does a health claim get authorised?

By journey: an applicant submits human evidence with dose and population defined, an independent scientific body assesses substantiation, an authorisation decision fixes the exact wording and conditions, and the sentence joins the register.

Why can a product with a tiny amount of a vitamin not make its claim?

Conditions of use: an authorised claim may be made only when the product contains a significant amount, typically at least 15% of the nutrient reference value per portion, so token doses cannot borrow real claims.

What is the on-hold list?

Botanical claims submitted but never finally assessed, on which ashwagandha, ginkgo and their kin sit in a limbo that permits provisional loose use under national rules while firm claims remain unauthorised.

Who enforces supplement health claims?

Local authority trading standards on labels, the Advertising Standards Authority on advertising including websites and social media, and marketplaces on listings, reactively, which is why unauthorised claims survive until reported.
