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.

Anything you already take or are considering?

Name it and the finder says whether the register authorises any claim for it for your goals, or refused one, or has never assessed it.

None yet. Type an ingredient in the box above, for example “magnesium” or “turmeric”.

Thyroid and Weight and Mood

15 capsules across 13 ingredients

Thyroid. Only iodine and selenium hold authorised register wording about the thyroid, quoted exactly on their pages. Thyroid conditions are diagnosed and managed by a GP, and the British Thyroid Foundation 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.

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.

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.
