Iron supplements can help to prevent and correct iron deficiency common in young women but also seen in children and among people taking drugs that reduce stomach acid. Iron supplementation may also reduce unexplained fatigue in women of child-bearing age, inhibit dry cough associated with ACE inhibitors, and reduce symptoms of restless legs syndrome in people with low ferritin levels.
