Iron is a mineral which helps maintain healthy blood. Hemoglobin, a part of red blood cells, holds the iron.
Oxygen binds to the iron and is carried by red blood cells to provide oxygen to all cells.
Having enough iron in our bodies helps us perform well in work and play. The iron you need depends on your age and gender. Women need more than men because of monthly blood loss. Pregnant women need even more for the growing baby. If you are getting too little iron in your diet you can develop an iron deficiency, called anemia.
