Iron is an important mineral that is vital for the human body. It plays a crucial role in the formation of hemoglobin, the red pigment in the blood that is responsible for oxygen transport in the body. An iron deficiency can therefore lead to anemia, fatigue and reduced performance.
In medicine, iron is often used as a dietary supplement to treat or prevent iron deficiency conditions. Iron is also taken for certain diseases where iron requirements are increased, such as anemia. It is important that iron be taken under a doctor's supervision to ensure proper dosage and to avoid possible side effects.
Foods such as meat, fish, legumes and whole grains are good sources of iron.
