Iron is an essential mineral for the maintenance of normal blood composition. In fact iron plays an important role in terms of the capacity of blood to carry oxygen and in terms of forming red blood cells and haemoglobin. Deficiencies in iron often lead to fatigue and less endurance. Furthermore iron ensures that sufficient oxygen can be stored in our muscles (which is important for physical exercise and sport). Iron also plays an important role in a variety of (enzymatic) processes which occur in the body cells for the purpose of a normal energy build-up. In other words, iron is an essential mineral in a number of processes which ensure a sufficient energy level in the human body. Moreover, iron plays an important role in our cell division, in the normal function of our immune system and in the maintenance of our cognitive functions.
