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.

Testosterone and Mood

949 capsules across 13 ingredients

Testosterone. Only a small number of ingredients hold register claims mentioning testosterone, and this page quotes them exactly. Claims in this category are heavily marketed well beyond what the register authorises; the split below shows the line.

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.
