How Food Supplements Are Regulated in Great Britain
Food supplements sold in Great Britain are regulated under The Food Supplements (England) Regulations 2003, with equivalent legislation in Scotland and Wales. The Food Standards Agency (FSA) oversees compliance. Key points for consumers:
Food supplements are not medicines
A product sold as a food supplement cannot legally be marketed as treating, curing or preventing any disease. Only licensed medicines may make such claims. If a supplement makes medical claims, this is a red flag and may indicate non-compliance with UK regulations.
Permitted health claims must be authorised
Health and nutrition claims on food and supplement labels in Great Britain must be listed in the retained GB register of authorised claims (derived from EU Regulation 1924/2006 and Regulation 432/2012). Claims not on this list may not be used.
Novel foods and botanical ingredients
Some botanical ingredients require authorisation as novel foods before they may be sold. Established botanical ingredients with a documented history of use (such as guarana and green coffee extract) are generally treated under traditional use provisions, though specific extract concentrations may be subject to additional review.
