Doubling the Iron Dose to Prevent IDA in Twin Pregnant Women

Summary

In twin pregnancies, the maternal iron demands are magnified, estimated at 1.8 times more than in singleton pregnancies due to greater maternal red blood cell mass and plasma volume expansion as well as increased fetal and placental requirements. With a lack of randomized controlled trials assessing the adequacy of iron supplements on twin pregnancy, various recommendations are based on level 3 clinical expert opinions at most.
