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.

Thyroid and Heart and Mood

13 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.

Heart. This page collects ingredients whose register claims relate to the heart, blood pressure or cholesterol, quoted exactly. Diet, movement and prescribed medication come first in this area, and the British Heart Foundation below is the specialist charity for reliable information.

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.
