Teeth and gums and Focus and Fertility

1418 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.

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.

Fertility. Ingredients here hold register claims relating to fertility and reproduction, quoted exactly. UK guidance on folic acid before and during early pregnancy is the best-established nutritional advice in this area, and Fertility Network UK below offers wider support.

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.
