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 Libido and Skin, hair and nails

15 capsules across 22 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.

Libido. Almost no ingredient holds an authorised register claim in this area, which is itself useful information: sellers may not claim what is not authorised. What people discuss appears below with its actual register status.

Skin, hair and nails. The register authorises specific wording for several nutrients relating to normal skin, hair or nails, and this page collects them with the wording quoted exactly. Marketing in this category runs far ahead of the register; the split below shows exactly where the line sits.

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.
