Iron Supplementation During Pregnancy - One Versus Two Ferrous Sulfate Capsules for Iron Deficient Pregnant Women

Since normal pregnancies are associated with dilutional anemia, due to a greater increase in plasma volume with a smaller increase in RBC mass, it is important to properly diagnose IDA according to the levels of serum ferritin. Previous studies examining the optimal iron dose have shown that adjustment of iron supplementation according to serum ferritin levels in early pregnancy could be beneficial. Nonetheless, there is no consensus regarding the appropriate dose of iron during pregnancy, its dose-response curve and its effect on serum ferritin levels. In this trial the investigators sought to assess the efficacy of doubling the daily iron supplement dose in pregnant women with IDA.
