How does iron relate to restless legs syndrome?

ANSWER

Not enough iron in the diet is one cause of restless legs syndrome. Taking iron pills may improve RLS in these people.

Even in people who are not anemic and have normal iron levels, iron levels may be involved. Studies show a "brain iron deficiency" in many people with restless legs syndrome. A doctor may prescribe iron supplements even if a person's iron levels are within normal range. However, too much iron can lead to liver damage and other health problems.
