Iron supplements are substances taken by mouth to increase the amount of iron in the body. Iron is a mineral that is important for many bodily functions, including the production of red blood cells, which carry oxygen throughout the body.
Iron deficiency is the most common nutrient deficiency in the world. It can cause anemia, a condition in which the body does not have enough healthy red blood cells. Symptoms of iron deficiency anemia can include fatigue, weakness, shortness of breath, pale skin, and a cold feeling in the hands and feet.
Iron supplements can be helpful for people with iron deficiency anemia or who are at risk for iron deficiency. However, it is important to talk to your doctor before taking iron supplements, as too much iron can be harmful.
