Teeth and gums and Blood and iron and Mood

15 capsules across 19 ingredients

Teeth 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.

Blood and iron. Ingredients here hold register wording about normal red blood cell formation, oxygen transport, iron absorption or normal blood clotting, quoted exactly on their pages. Suspected iron deficiency needs a blood test before a supplement; the NHS page below explains why.

Mood. The register authorises wording for some nutrients relating to normal psychological function, and this page shows which, quoted exactly. Low mood that persists deserves real support rather than a capsule; Mind's information and helplines below are a good place to start.

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.
