Find capsules by goal

Say what you want help with. The finder shows what the GB register lets any seller claim for it, what the register assessed and refused, and the cheapest capsules per capsule for each ingredient. It quotes; it never advises.

Teeth and gums and Mood and Focus

1400 capsules across 45 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.

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.

Focus. Some nutrients hold register claims relating to normal cognitive or psychological function, quoted exactly on their pages. The wording is precise and worth reading as written; anything beyond it is marketing, not authorised claim.

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.
