Iron supplements are an effective treatment for iron deficiency or iron deficiency anemia. While mild iron deficiency can sometimes be corrected by adding iron-rich foods to the diet, supplements are needed for moderate to severe deficiency. Most people with symptoms of iron deficiency anemia are able to increase iron levels to the normal range within two or three months of taking iron supplements.
Importance of Iron
Iron is necessary for the production of functional hemoglobin. This red blood cell protein transports oxygen from the lungs to all tissues and cells of the body. When your do not have adequate hemoglobin or sufficient red blood cells, your body does not get the oxygen-rich blood that it needs. This results in a condition called iron deficiency anemia.
Symptoms of Deficiency
Iron deficiency anemia may cause tiredness, fatigue, weakness, dizziness, irritability, shortness of breath or depression. Other signs may include pale skin, brittle nails, chest pain, cold hands or feet or an irregular heartbeat. Less common symptoms of anemia include pica, an urge to eat ice and other nonfood items. Low iron may also cause sexual dysfunction and problems concentrating on mental tasks.
At-Risk Populations
Women of childbearing age are at risk of iron deficiency anemia because they lose blood each month during their period. During pregnancy, many women become anemic as additional iron is needed to supply the growing infant. Children may become anemic during a growth spurt, when the body's iron stores cannot keep up with increased demand. People with kidney failure, those with ongoing blood loss such as that caused by gastrointestinal bleeding and cancer patients receiving chemotherapy are at risk of developing anemia. Elderly persons and those with chronic inflammatory conditions may need iron supplements.
Supplement Facts
Before beginning any new vitamin supplement, you should consult your health care provider. Iron supplements interact with a variety of medications, and overdose is harmful. You doctor will measure your blood iron levels and determine whether a supplement is right for you. Iron supplements often cause side effects that affect digestion, including nausea, vomiting, stomachache and constipation. You can reduce these effects by taking the supplement with a meal and increasing your consumption of fiber and water. Vitamin C helps the body absorb iron, so take your supplement with a glass of orange juice or another food rich in vitamin C.
