Digestion and Sleep
362 capsules across 22 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.
Sleep. Almost nothing holds an authorised GB register claim about sleep, and that absence is worth knowing in itself: sellers may not claim it either. Ingredients people discuss for sleep appear below with their actual register status, and The Sleep Charity offers evidence-based sleep advice.
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.
