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.

Joints and Focus and Thyroid and Eyes

1206 capsules across 55 ingredients

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.

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.

Thyroid. Only iodine and selenium hold authorised register wording about the thyroid, quoted exactly on their pages. Thyroid conditions are diagnosed and managed by a GP, and the British Thyroid Foundation is the specialist charity.

Eyes. Ingredients here hold register claims relating to the maintenance of normal vision, quoted exactly on their pages. Regular sight tests catch what supplements never will; the Macular Society and RNIB below are the specialist organisations.

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.
