What a food supplement is
A food supplement is defined as ‘any food the purpose of which is to supplement the normal diet and which is a concentrated source of a vitamin or mineral or other substance with a nutritional or physiological effect, alone or in combination and is sold in dose form’.
A wide range of nutrients and other ingredients might be present in food supplements. These can include
- vitamins
- minerals
- amino acids
- essential fatty acids
- fibre
- various plants and herbal extracts
Food supplements are intended to correct nutritional deficiencies, maintain an adequate intake of certain nutrients, or to support specific physiological functions. They are not medicinal products and as such cannot exert a pharmacological, immunological or metabolic action. Therefore, their use is not intended to treat or prevent diseases in humans or to modify physiological functions.
In the UK, food supplements are required to be regulated as foods and are subject to the provisions of general food law. In Northern Ireland, EU food law relating to food supplements will continue to apply, as listed in the Northern Ireland Protocol.
Registration
To sell food supplements you must register as a Food Business Operator (FBO) with your local authority.
Selling your products
It is your responsibility to ensure that food supplements you sell are safe for consumption. There are certain things you should do to make sure they are safe.
Using a reputable supplier
Your supplier should be registered as a business with their local authority and provide fully referenced invoices and receipts.
Don’t buy supplements over the internet unless you are confident the supplier is reputable.
Beware of counterfeit products, particularly if you are buying products on the internet and the product price is cheaper than other suppliers.
It is illegal to sell 2,4-dinitrophenol (DNP) for human consumption in the UK. It has been sold as a diet pill for weight loss however, it is a highly toxic industrial chemical and is not fit for human consumption.
You should report anyone selling DNP immediately to the local police, the local authority, Crimestoppers or through the National Food Crime Unit. Our page on DNP has further information on the dangers of this chemical.
Keeping records
Keep records so you can identify the business you bought food supplements from and who you sold them to. You must also keep documents like invoices and delivery notes and produce these documents if they are requested by enforcement authorities.
Labelling
Make sure the food supplements you sell are labelled correctly. If they are not, contact you supplier and arrange for return of the products or do not accept them in the first place.
Importing supplements
If you import supplements into the UK, you are legally responsible for all aspects of those goods, including composition, safety and labelling of the products.

Changes from 1st January 2021
Food supplements are regulated by legislation made in each part of the UK (please see the Legal requirements section above). These Regulations cross refer to the Annex of Directive 2002/46/EC, which sets out rules for vitamins and minerals used in food supplements. On 1 January 2021 The Nutrition (Amendment etc.) (EU Exit) Regulations 2019 and The Nutrition (Amendment etc.) (EU Exit) Regulations 2020 came into force. These transferred responsibilities for the regulation of food supplements from EU organisations involved in the risk assessment and risk management processes to appropriate authorities and bodies in GB and reflected the Protocol on Ireland / Northern Ireland. Therefore, from 1 January 2021 the UK has its own list of Vitamins and Minerals for use in Food Supplements and modification processes in Great Britain. For further information on these requirements, visit The Nutrition (Amendment etc.) (EU Exit) Regulations and see Guidance notes on legislation implementing Directive 2002/46/EC on food supplements.
