Iron is an essential mineral, necessary for the several crucial functions of the body. In addition to the production of haemoglobin in the blood required for the transportation of oxygen in different parts of the body, iron helps to keep your hair, skin and nail health. Even after being such an important mineral, you will be surprised to know that a large number of people across the globe are suffering from the problem of iron deficiency anaemia. Women belonging to the menstruating age group are more prone to this deficiency as compared to others. Going by the numbers about 20 per cent of women, 50 per cent of pregnant women, and 3 per cent of men do not have enough iron in their body. The symptoms may include fatigue, dizziness, headaches, sensitivity to cold and shortness of breath.
