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 Fertility and Blood sugar

1255 capsules across 33 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.

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.

Blood sugar. A small number of ingredients hold authorised register wording about normal blood glucose levels, quoted exactly on their pages; a much larger number of claims about blood sugar were assessed and refused. Nothing here is about treating or preventing diabetes, and anyone managing blood glucose should follow their care team's advice. Diabetes UK is the specialist charity.

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.
