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.

Blood sugar and Eyes and Tiredness and fatigue

12 capsules across 17 ingredients

Blood 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.

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.

Tiredness and fatigue. The register's phrase is 'a reduction of tiredness and fatigue', and a surprising number of everyday nutrients hold that authorised wording. This page shows which, quoted exactly, alongside ingredients people discuss without an authorised claim. Persistent tiredness is worth raising with a GP; the NHS link below covers self-help basics.

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.
