Digestion and Stress
355 capsules across 28 ingredientsDigestion. 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.
Stress. Very few ingredients hold authorised register claims in this area, and this page is honest about that: the split below shows what may be said and what may not. Ingredients people discuss for stress appear with their register status, and Mind's resources cover support that goes 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.
