Sourcing and selling food supplements legally in the UK requires careful attention to food safety law, novel food status, permitted health claims, accurate labelling and notification procedures. Getting any of these wrong can lead to products being seized, fines or having to withdraw stock.
This guide walks through the main steps early-stage founders and e-commerce sellers should follow, from choosing suppliers to placing products on the market. The rules are the same whether you manufacture in the UK, source from the EU or import from further afield.
Understanding the regulatory framework
Food supplements are classified as food under UK law and must comply with the Food Safety Act 1990, the Food Information Regulations and specific supplement rules. The Food Standards Agency (FSA) is the main authority. All products must be safe, properly labelled and, where applicable, notified before sale.
Decide early whether your intended ingredients are already permitted. Novel foods – those not consumed to a significant degree in the UK before 1997 – need authorisation. Many botanicals, new extracts and synthetic sources fall into this category. Check the FSA novel foods catalogue before committing to a supplier.
Sourcing suppliers and samples
Start with UK or EU manufacturers that already hold existing notifications for the same ingredients. This reduces your own novel food burden. Search trade directories, attend industry events such as the Natural Products Expo or use platforms that connect brands with certified factories. Overseas options in India, China or the US are common but require extra import checks.
Request samples only after signing a non-disclosure agreement. Test at least three batches for identity, purity and absence of contaminants. Use a UKAS-accredited laboratory. Ask for certificates of analysis, manufacturing process descriptions and evidence of previous FSA notifications if the ingredient is not on the permitted list. Minimum order quantities often start at 5–25 kg for capsules or tablets; negotiate only after confirming regulatory compliance.
Quality control and importing
Establish a specification that includes limits for heavy metals, microbes, pesticides and residual solvents. Insist on third-party testing at the point of manufacture and again on arrival in the UK. For imports, calculate duties and check whether the product needs an import notification or veterinary certificate.
Use a freight forwarder experienced in food supplements. They can manage customs declarations through the Customs Declaration Service. Keep records of every shipment for at least two years. If the product is novel and unauthorised, even small test imports can trigger enforcement action. Verify that your chosen supplier can provide full traceability from raw material to finished goods.
Novel food authorisation process
If an ingredient is novel you must submit an application to the FSA. The process involves compiling a dossier with detailed compositional data, exposure estimates, toxicological studies and a safety assessment. Expect the review to take many months and possibly require additional data. Until authorisation is granted you cannot sell the product lawfully in Great Britain.
Some ingredients benefit from the retained EU novel food catalogue entries or from the temporary Northern Ireland protocol rules. Always confirm current status on the FSA website rather than relying on supplier assurances. Many founders begin with established ingredients such as vitamin D3, magnesium citrate or turmeric extract with curcumin to avoid this lengthy process entirely.
Health claims and labelling requirements
Only authorised health claims listed on the UK Nutrition and Health Claims Register may be used. You cannot say a product “boosts immunity” or “reduces stress” unless the exact wording and conditions of use are met. Structure-function statements such as “calcium contributes to normal muscle function” are allowed when the nutrient level meets the threshold and the full claim is shown.
Labels must include the name of the food, a list of ingredients in descending order, nutrition information, portion size, recommended daily intake, a warning not to exceed the stated dose, and a statement that supplements do not replace a varied diet. All text must be clear, legible and in English. Include your business name and address or the registered address of the responsible person. Many founders use contract manufacturers that provide pre-approved label templates to reduce risk.
Notification and placing on the market
Before selling, notify the FSA via the online food supplements notification system if the product contains vitamins, minerals or certain other ingredients. Submit the exact label and composition. The FSA does not approve the product but uses the information for monitoring. Keep a copy of the confirmation email.
Register your food business with your local authority if you handle or store supplements. Check current requirements on GOV.UK because notification portals and business registration rules can change. Once notified and labelled correctly you may begin sales through your own website, marketplaces or retail partners. Monitor post-market surveillance and keep complaints records.
Practical next steps for founders
Begin with a single product using fully permitted ingredients to test your sales process. Build a technical file containing supplier agreements, test results, labels and notification confirmations. Review the file every time you change batch, supplier or formulation. Many early-stage teams work with regulatory consultants for the first product only, then manage subsequent variants in-house.
Loomworks in Liversedge offers selected founders free desks, a registered address and mentoring that can help while you refine compliance and sourcing. Once your systems are robust you can scale with confidence, adding new products only after repeating the checks above.
Frequently asked questions
Can I sell food supplements without FSA notification?
No. Most supplements containing vitamins, minerals or listed botanicals must be notified to the FSA before they are sold in the UK. The notification is free but mandatory. Failure to notify can result in enforcement action including product withdrawal.
What is a novel food and how do I check?
A novel food is any ingredient not eaten to a significant degree in the UK before 15 May 1997. Search the FSA novel foods catalogue. If your ingredient is absent or listed as unauthorised you will need to submit a full application before selling.
Are health claims on supplement labels restricted?
Yes. Only claims authorised by law may appear. You must use the exact wording from the UK register and meet the conditions of use. General wellness statements that imply unapproved benefits are not allowed and can lead to regulatory action.
Do I need different labels for UK and EU sales?
After the UK left the EU, labelling rules diverged. Great Britain uses UK-specific nutrition and health claim lists and address formats. Northern Ireland follows EU rules. If you sell into the EU you must comply with EU language, notification and novel food requirements separately.
How do I find compliant overseas suppliers?
Look for factories that already supply the UK market and can provide existing FSA notification references, full certificates of analysis and traceability documents. Visit or audit where possible and always test incoming batches in a UK laboratory.
