Selling Dietary Supplements in the UK

Selling dietary supplements (food supplements) in the UK requires compliance with a specific regulatory framework that treats these products as food rather than medicines. Understanding UK food-supplement regulations is essential before placing products on the market in Great Britain or Northern Ireland.

UK Food Supplement Regulations: What Sellers Need to Know

Food supplements in Great Britain are regulated under the Food Supplements (England) Regulations 2003 (and equivalent regulations in Scotland and Wales), together with retained EU food law as amended post-Brexit. The Food Standards Agency (FSA) and devolved authorities oversee the framework. In Northern Ireland, rules are influenced by the Windsor Framework.

There is no pre-market notification or registration requirement for food supplements in Great Britain (unlike many EU member states). However, any business selling food supplements must register as a Food Business Operator (FBO) with the local authority. Products must comply with compositional rules, labelling requirements and general food safety law. Brands that treat UK supplements as interchangeable with U.S. dietary supplements or current EU products frequently encounter compliance barriers, especially around permitted vitamin/mineral forms and health claims. A clear understanding of the overall framework is therefore the necessary starting point.

Which Ingredients Can Be Used in UK Food Supplements?

The UK maintains its own list of permitted vitamins, minerals and their chemical forms (now independent from the EU Annexes following post-Brexit divergence). Only the listed forms may be used. Not every form accepted in the EU or other markets is automatically permitted in the UK.

For substances other than vitamins and minerals (botanicals, amino acids, probiotics, etc.), safety must be demonstrated and the ingredient must not render the product a medicine. Certain substances (e.g., kava-kava) are prohibited. UK requirements therefore demand careful checking of the current permitted substances list and any national restrictions.

Novel Food and Borderline Issues

An ingredient used in a food supplement may fall under UK novel food rules if it was not used significantly in the UK/EU before the relevant cut-off date. Novel food status can apply to new botanical extracts, new forms of existing substances or ingredients with a history of use only outside the UK/EU.

If an ingredient is novel, it generally cannot be used until authorised. Borderline products that may be considered medicinal should be checked with the Medicines and Healthcare products Regulatory Agency (MHRA). Relying solely on a history of safe use in a third country is not sufficient. Early assessment of novel food or borderline status is a critical part of UK compliance.

UK Supplement Labelling Requirements

Labels must comply with retained Regulation (EU) No 1169/2011 and the specific Food Supplements Regulations. The product must be labelled as a “food supplement” (not “dietary supplement”). Mandatory particulars include:

- The name “food supplement”

- The names of the categories of nutrients or other substances that characterise the product

- The recommended daily dose

- A warning not to exceed the stated recommended daily dose

- A statement that food supplements should not be used as a substitute for a varied diet

- A statement that the product should be stored out of the reach of young children

- Name and address of the responsible food business operator established in the UK (or importer)

- List of ingredients, allergens, net quantity, best-before date and batch number

Incomplete, poorly translated or U.S.-style labels are common reasons for enforcement action.

Nutrition and Health Claims for Supplements in the UK

Health claims are regulated under retained Regulation (EC) No 1924/2006, with the GB Nutrition and Health Claims Register applying in Great Britain. Only claims authorised on the GB register may be used, under the specified conditions of use. Disease-related claims (prevention, treatment or cure) are prohibited for food supplements.

Many structure/function-style statements common in other markets are not authorised. Claims authorised in the EU after Brexit are not automatically authorised in Great Britain. Using unauthorised or poorly worded claims is one of the highest-risk compliance areas. Brands must align all on-pack and promotional language with authorised claims on the GB register.

Common Mistakes When Selling Supplements in the UK

Frequent errors include:

- Using the term “dietary supplement” instead of “food supplement”

- Applying EU-authorised claims that are not on the GB register

- Using vitamin or mineral forms not permitted under the UK list

- Missing the mandatory UK business address on the label

- Making medicinal or disease-related claims

- Failing to register as a Food Business Operator

- Assuming an EU-compliant product is automatically acceptable in Great Britain without checking post-Brexit divergences

These oversights often surface during local authority inspections or market surveillance and can result in product recalls, improvement notices or costly reformulation.
