Our Spring Valley Slow-Release Iron Tablets, 45 mg is a dietary supplement for iron deficiency and iron deficiency anemia*, when the need for such supplementation has been determined by a doctor. Iron deficiency is most common among women (approximately 11% of U.S. women). Each tablet delivers 45 mg of elemental iron (144 mg of dried ferrous sulfate). Iron is an essential mineral that supports normal red blood cell formation.* This formula has a timed-release delivery system that gradually releases iron over a period of time, which may reduce gastrointestinal (GI) side effects such as nausea and abdominal discomfort common with iron supplementation. The suggested adult dosage is one tablet daily or as recommended by a doctor.
