Teeth and gums and Mood and Bones and Joints

1331 capsules across 50 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.

Mood. The register authorises wording for some nutrients relating to normal psychological function, and this page shows which, quoted exactly. Low mood that persists deserves real support rather than a capsule; Mind's information and helplines below are a good place to start.

Bones. Ingredients here hold register claims relating to the maintenance of normal bones, quoted exactly on their pages. Weight-bearing exercise and dietary calcium are the foundations, and the Royal Osteoporosis Society is the specialist charity for anything further.

Joints. Joints carry the largest set of refused claims in the register: glucosamine, chondroitin, MSM, turmeric and collagen-for-joints wording were all assessed and turned down. What is authorised is narrow and quoted exactly on the ingredient pages: vitamin C for normal collagen formation for the normal function of cartilage, and manganese for normal formation of connective tissue. Versus Arthritis is the specialist charity for anything beyond nutrition.

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.
