Overview Information
Iron is a mineral. Most of the iron in the body is found in the hemoglobin of red blood cells and in the myoglobin of muscle cells. Iron is needed for transporting oxygen and carbon dioxide. It also has other important roles in the body. Iron is most commonly used for preventing and treating anemia caused by low iron levels. It is also used for anemia caused by abnormal heavy bleeding during menstrual periods (menorrhagia), pregnancy.
How does it work?
Iron helps red blood cells carry oxygen from the lungs to cells all over the body. Iron also plays a role in many important functions in the body.
Iron Deficiency Directory
Iron helps your body get oxygen through the bloodstream. Without iron, fewer red blood cells can be made, which causes anemia. Iron levels can get too low because of bleeding, due to heavy menstruation or other problems, such as ulcers. It can also be caused by simply not getting enough iron through your diet. Common symptoms of an iron deficiency include fatigue, dizziness, and moodiness, along with other symptoms. Treatments include taking iron supplements.
