A clear guide to UK regulations, FSA registration, and labelling compliance for legally selling health supplements.
The short answer is no, there is no specific “supplement licence” required to sell vitamins or minerals in the UK. However, the regulatory landscape is heavily enforced, and trading without proper business registration or compliant labelling is illegal.
FBO Registration
Food Standards
Medical Boundaries
Whether you are an aspiring e-commerce entrepreneur, a gym owner, or a pharmacy buyer, understanding the legal framework for supplements is critical. The single most important fact to grasp is that UK food supplements are regulated as a category of food under general food law, not as medicines.
Because they are classified as food, there is no requirement to register individual food supplements in the UK. As long as they comply with applicable food law, they are permitted for sale. However, the person or company selling them must adhere to strict operational, formulation, and labelling regulations. Here is the definitive guide to legally selling supplements in the UK.
1. Register as a Food Business Operator (FBO)
While you do not need a product-specific licence, business registration is an absolute legal requirement. If you sell food supplements, you must register as a Food Business Operator (FBO) with your local authority.
The 28-Day Rule
You must register as a food business operator (FBO) with the local council at least 28 days before operating.
It is Mandatory
Registration is not an approval you can be refused, but trading without it is non-compliant. It is free and done through your local council.
Legal Responsibility
As the FBO, you have the responsibility to ensure the safety of food before placing it on the UK market.
2. Food vs. Medicine: The MHRA Boundary
The quickest way to inadvertently require a legitimate licence is to cross the boundary between food and medicine. Supplements are meant to supplement a normal diet and cannot exert a pharmacological, immunological or metabolic action.
Do Not Make Medical Claims
If you cross that line—in formulation or in how you present the product—the MHRA can classify it as a medicine, which needs a full medicinal authorisation (a genuine licence) instead. You cannot claim or imply a supplement treats, prevents or cures a disease.
3. Permitted Ingredients and Novel Foods
You cannot simply place any ingredient into a capsule. Only ingredients listed under UK food law are allowed.
FSA Authorisation for Novel Foods
The regulations set out which vitamins and minerals, and which specific chemical forms of them, may be used in food supplements. Furthermore, ingredients classified as novel foods (e.g. CBD, some botanicals) require FSA authorisation before they can be legally sold.
4. Mandatory Labelling Requirements
Even without a product licence, a supplement label must comply with extremely strict regulatory guidelines to be legally viable for retail or e-commerce.
| Requirement | Legal Specifics |
|---|---|
| Product Name | Must describe the product as a “food supplement” (not “dietary supplement”). |
| Ingredients & Allergens | Must include a complete ingredient list with allergens in bold or emphasised. |
| Mandatory Warnings | Must state the recommended daily dose with a warning not to exceed it, and carry a statement that supplements are not a substitute for a varied diet. |
| Traceability | Must display your business name and UK address (as the legally responsible FBO). |
5. Authorised Health Claims
Marketing your product incorrectly is the fastest way to invite regulatory action from Trading Standards.
You may only use nutrition and health claims that appear on the Great Britain Nutrition and Health Claims Register. For example, you must use authorised phrases like: “Vitamin D contributes to normal immune function”. Since Brexit, note the GB register has diverged from the EU one, so an EU-authorised claim is not automatically valid here.
How a UK Manufacturer Keeps You Compliant
Navigating these regulations alone is a major risk for new business owners. By partnering with an accredited B2B manufacturer like Liquid Creations Ltd, you safeguard your brand from legal pitfalls.
Formulation Auditing
A reputable manufacturer ensures that if a vitamin or mineral — or the particular form you want to use — is not on the permitted list, it cannot lawfully go into a supplement. They check all ingredients prior to production.
Label Compliance
Manufacturers can review your packaging artwork before printing to verify that all mandatory warnings, allergen emphasis, and Great Britain health claims are legally compliant and accurately reflect the product contents.
