UK Food Supplements Readiness: FSA, the GB NHCR and the Windsor Framework Split
The UK no longer follows EU food supplement law in lockstep, but most of the operative rules still trace back to Directive 2002/46/EC carried into domestic law by the Food Supplements (England) Regulations 2003 and parallel instruments for Scotland, Wales and Northern Ireland. Post-Brexit divergence shows up in three places: the GB Nutrition and Health Claims Register (separate from the EU 1924/2006 register since 1 January 2024 with the GB-only authorisation pathway), the Windsor Framework split that keeps Northern Ireland under EU rules while Great Britain runs its own, and the FSA / FSS enforcement posture which leans heavily on local authority trading standards rather than a central notification gate. This guide maps the UK-specific surface area a supplement brand has to operate against.

The four UK instruments that actually govern a supplement
The Food Supplements (England) Regulations 2003 (and the equivalent Scottish, Welsh and Northern Irish instruments) implement Directive 2002/46/EC into UK law and define a food supplement, the permitted vitamin and mineral substances, and the mandatory labelling particulars. The Nutrition and Health Claims (England) Regulations 2007 implement what was Regulation 1924/2006 and now point at the GB NHCR. The Food Information Regulations 2014 carry Regulation 1169/2011 (allergen labelling, mandatory particulars) into GB. The General Food Regulations 2004 carry Regulation 178/2002 (general food law, traceability, withdrawal, recall, RASFF-equivalent notification to the FSA). Together these four set the baseline that every UK-marketed supplement is checked against.
No central notification — but eight things the FSA still expects
Unlike France or Italy, the UK does not operate a pre-market notification gate for ordinary food supplements (a novel food under retained Regulation 2015/2283 still needs FSA authorisation). What the FSA and the local authority trading-standards officers expect on file: (1) compositional specification with vitamin/mineral forms from Annex II as retained in UK law; (2) declared portion, nutrient reference values and percent NRV; (3) all mandatory FIC particulars including the 14 allergen highlights; (4) any health claim mapped to a GB NHCR authorised entry; (5) HACCP-equivalent food safety plan; (6) traceability one-step-back, one-step-forward; (7) withdrawal and recall procedure; (8) named UK Food Business Operator (FBO) address on label. The absence of a notification gate does not mean absence of scrutiny — it means scrutiny lands at audit and at complaint.
GB NHCR — the divergence that became real on 1 January 2024
Until 1 January 2024 the UK accepted EU-register claims under retained 1924/2006. From that date the GB Nutrition and Health Claims Register became the operative list for Great Britain. The starting set was the retained EU list, but additions and removals now diverge — a claim authorised at EU level after that date is not automatically authorised in GB, and an application to add a claim now goes through FSA / FSS / Food Standards Wales rather than EFSA. Northern Ireland under the Windsor Framework continues to follow the EU 1924/2006 register. A UK-wide SKU therefore needs claims that are either on both registers or rendered conditionally per market.
Windsor Framework — the GB vs NI split that affects label, claims and notification
Under the Windsor Framework, Northern Ireland continues to apply EU food law for goods placed on the NI market: EU Annex II vitamin/mineral forms, EU 1924/2006 claims register, EU 2015/2283 novel food regime, and 'Not for EU' labelling where applicable on goods moved from GB to NI under the green-lane arrangements. Great Britain operates the retained UK versions of the same rules. A single SKU sold across the UK either complies with both regimes simultaneously or runs two SKUs. The operational implication: a GB-only health claim cannot appear on an NI-bound label; an EU-only novel ingredient cannot be sold in GB without FSA authorisation.
Enforcement posture — local authorities, primary authority partnerships, and the Ashbury Health letters
Day-to-day enforcement is run by local authority environmental health and trading standards officers, with the FSA as the central competent authority. A supplement brand can voluntarily enter a Primary Authority Partnership under the Regulatory Enforcement and Sanctions Act 2008, which gives one local authority lead status and binds the rest. Recent enforcement themes: melatonin (treated as a medicinal product unless dose and presentation say otherwise), CBD as a novel food (FSA published authorisation list since 2024), and unsubstantiated immune / weight-loss claims (FSA + ASA joint action). The FSA's 'Allergen Alerts' system is the public-facing recall mechanism.

Frequently asked
Do I need to notify the FSA before selling a food supplement in the UK?
Not for ordinary supplements — there is no Article 10-equivalent UK notification gate. Novel foods under retained Regulation 2015/2283 do require FSA authorisation. The day-to-day check happens at audit and complaint via local authority trading standards.
Can I use EU-authorised health claims on a UK label?
Only if the same claim is on the GB NHCR for products sold in Great Britain. Northern Ireland continues to follow the EU 1924/2006 register under the Windsor Framework. A UK-wide SKU needs claims on both registers or two label variants.
Is CBD legal in UK food supplements?
CBD is a novel food. FSA maintains a public list of CBD products that have a validated novel food authorisation application. A CBD supplement sold in GB must be on that list. NI follows the EU novel food regime separately.
What is the Windsor Framework's impact on supplement labels?
Goods placed on the NI market follow EU food law (Annex II vitamin forms, EU claims register). GB-only goods follow the UK retained regime. A SKU sold UK-wide must comply with both, or be split into GB and NI variants with the appropriate 'Not for EU' marking where the green-lane rules require it.
