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.

Blood and iron and Teeth and gums and Skin, hair and nails

15 capsules across 24 ingredients

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.

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.

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.
