Teeth and gums and Digestion and Tiredness and fatigue
565 capsules across 48 ingredientsTeeth and gums. The register authorises wording about the maintenance of normal teeth for several minerals and vitamins, quoted exactly on their pages. Brushing, fluoride and regular check-ups do the real work; the Oral Health Foundation is the specialist charity.
Digestion. The register authorises specific wording about digestion for a few nutrients, quoted exactly on their pages, and refused most of the probiotic and gut wording sellers reach for. The split below is the honest picture. Persistent digestive symptoms are a matter for a GP, and Guts UK is the specialist charity.
Tiredness and fatigue. The register's phrase is 'a reduction of tiredness and fatigue', and a surprising number of everyday nutrients hold that authorised wording. This page shows which, quoted exactly, alongside ingredients people discuss without an authorised claim. Persistent tiredness is worth raising with a GP; the NHS link below covers self-help basics.
Nothing here is medical advice. The wording is the GB register's, quoted exactly; whether a product qualifies to use it is the seller's responsibility. Speak to a GP or pharmacist before taking a supplement, especially if you are pregnant, take medicines or have a diagnosed condition. Wording from the GB nutrition and health claims register; mapping reviewed 4 September 2026.
