Digestion and Mood and Joints

19 capsules across 16 ingredients

Digestion. The register authorises specific wording about digestion for a few nutrients, quoted exactly on their pages, and refused most of the probiotic and gut wording sellers reach for. The split below is the honest picture. Persistent digestive symptoms are a matter for a GP, and Guts UK 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.

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.
