Great Answer

Professionally Researched. (What's this?)

Iron's primary function in the body is to carry oxygen in red blood cells to the muscles. Iron also helps the body build bones, muscles and red blood cells.

Importance

Eating iron-rich foods can help your body transport oxygen more efficiently, which in turn allows the body to build muscle and exercise more vigorously, leading to increased calorie burn. Iron is also essential for athletes and active people.

Anemia

An iron deficiency can cause a low level of red blood cells, which in turn can cause iron-deficiency anemia. The symptoms of anemia are fatigue, paleness and susceptibility to infection.

Iron-Rich Foods

Heme iron is the type most easily absorbed by the body, and is often found in meat products. Non-heme iron can be found in dried beans and peas, eggs, dairy products and dark, leafy greens such as kale and spinach.

Required Amount

The amount of iron required for an individual varies by age and gender. Other factors, such as how your body stores and absorbs iron, can affect the amount of iron you need.

Iron Supplements

Iron supplements usually contain more than the recommended daily amount of iron. For this reason, it is best to consult a physician before beginning an iron supplement regimen.
