Iron is an essential mineral that is vital to your health. All of your cells contain some iron, but most of the iron in your body is in your red blood cells. Red blood cells transport oxygen from your lungs to the organs and tissues throughout your body. Iron promotes healthy pregnancy, increased energy, and better athletic performance.
A shortage of iron in the blood can lead to a range of serious health problems, including iron deficiency anemia. Symptoms of anemia include fatigue, weakness, dizziness and difficulty concentrating. Most people respond well to taking iron supplements and for those who are pregnant, menstruating, exercising, experiencing regular blood loss or on dialysis, taking a supplement may be a good way to achieve healthy iron levels.
