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.

Blood and iron and Heart

527 capsules across 41 ingredients

Blood and iron. Ingredients here hold register wording about normal red blood cell formation, oxygen transport, iron absorption or normal blood clotting, quoted exactly on their pages. Suspected iron deficiency needs a blood test before a supplement; the NHS page below explains why.

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.
