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.

Metabolism and Heart

16 capsules across 17 ingredients

Metabolism. The register's phrase is 'contributes to normal energy-yielding metabolism', and many everyday vitamins and minerals hold it. It is not a claim about weight or about feeling energetic, which is why this goal sits apart from Weight and from Tiredness and fatigue. Wording is quoted exactly on each ingredient page.

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.

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.
