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 Muscles

82 capsules across 24 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.

Muscles. Ingredients here hold register claims relating to normal muscle function or muscle protein, quoted exactly on their pages. Resistance exercise and overall protein intake are the fundamentals the claims assume; the NHS exercise guidance below is a good starting point.

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.
