why iron is important
Why is Iron so Important? Hemoglobin, which contains iron, is the part of red blood cells that carries oxygen from the lungs to all parts of the body, including muscles. Since your muscles need oxygen to produce energy, if you have low iron levels in your blood, you may tire quickly. Symptoms of iron deficiency include fatigue, irritability, dizziness, headaches and lack of appetite. Many times, however; there are no symptoms at all. A blood test is the best way to find out if your iron level is low.
