Iron is a mineral and one of its most important functions is transport of oxygen. Red blood cells contain a protein called haemoglobin. Haemoglobin is responsible for transferring the oxygen molecules we breathe in from our lungs to our cells. The component in haemoglobin that picks up, or binds with, the oxygen molecules is iron. Around two thirds of the iron in our body can be found in our haemoglobin. The red color of blood is due to its iron content.
