Iron Supplementation During Breastfeeding

Introduction to Iron Supplementation

The Centers for Disease Control and Prevention recommends that routine iron supplementation should be stopped at delivery for breastfeeding women without anemia, and no specific iron formulation or dose is recommended during lactation unless risk factors for postpartum anemia are present 1

The Centers for Disease Control and Prevention suggests screening for anemia at 4-6 weeks postpartum only if risk factors are present, such as anemia that continued through the third trimester, excessive blood loss during delivery, or multiple birth 1
If no risk factors exist, the Centers for Disease Control and Prevention recommends discontinuing supplemental iron at delivery 1

The Centers for Disease Control and Prevention and other guidelines recommend prescribing 60-120 mg of elemental iron daily using oral ferrous salts for breastfeeding women diagnosed with iron deficiency anemia 1, 2

The Centers for Disease Control and Prevention recommends rechecking hemoglobin after 4 weeks of treatment, expecting an increase of ≥1 g/dL 1, 2
If hemoglobin fails to increase by 1 g/dL despite compliance and absence of acute illness, additional testing including MCV, RDW, and serum ferritin should be performed 1
The Centers for Disease Control and Prevention suggests continuing treatment for 2-3 months after hemoglobin normalizes to replenish iron stores 1, 2

The World Health Organization recommends that women in the postnatal period maintain a balanced diet and drink sufficient clean water 3
Iron and folic acid supplementation should continue for 3 months after birth only if initiated during pregnancy for treatment purposes 3

The Centers for Disease Control and Prevention recommends not routinely supplementing iron in breastfeeding women without documented anemia or risk factors 1
The guidelines suggest ensuring calcium supplements and antacids are taken at different times, as they decrease iron absorption 4, 5
