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.

Digestion and Heart and Sleep

1452 capsules across 62 ingredients

Digestion. The register authorises specific wording about digestion for a few nutrients, quoted exactly on their pages, and refused most of the probiotic and gut wording sellers reach for. The split below is the honest picture. Persistent digestive symptoms are a matter for a GP, and Guts UK 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.

Sleep. Almost nothing holds an authorised GB register claim about sleep, and that absence is worth knowing in itself: sellers may not claim it either. Ingredients people discuss for sleep appear below with their actual register status, and The Sleep Charity offers evidence-based sleep advice.

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.
