Blood sugar and Weight and Focus
1188 capsules across 50 ingredientsBlood sugar. A small number of ingredients hold authorised register wording about normal blood glucose levels, quoted exactly on their pages; a much larger number of claims about blood sugar were assessed and refused. Nothing here is about treating or preventing diabetes, and anyone managing blood glucose should follow their care team's advice. Diabetes UK is the specialist charity.
Weight. The register takes a strict line on weight claims, and very little is authorised. This page shows the real status of ingredients people discuss for weight, quoted exactly. The NHS Better Health programme below is the evidence-based starting point.
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.
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.
