Iron is required by the human body to produce hemoglobin, the red blood cells that perform the vitally important task of transporting oxygen to all the cells of the body and returning carbon dioxide. Without enough iron, the body becomes anemic and suffers from lowered hemoglobin. Iron-deficient anemia can cause a feeling of lethargy and weakness and, in extreme cases, can even cause death. While a healthy diet is sufficient to maintain iron levels under normal conditions, additional sources of iron may be required for anemia associated with chronic disease or iron deficiency. Iron stores may be low in women experiencing particularly heavy menstrual flows, pregnancy, and kidney disease, blood loss from traumatic injuries or ulcers, celiac disease, Crohn's disease or due to medications. read more about iron » | find answers to your vitamins questions »
