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 Mood and Skin, hair and nails

554 capsules across 49 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.

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.

Skin, hair and nails. The register authorises specific wording for several nutrients relating to normal skin, hair or nails, and this page collects them with the wording quoted exactly. Marketing in this category runs far ahead of the register; the split below shows exactly where the line sits.

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.
