Iron Supplementation in Pregnancy: Boosting Maternal Health & Fetal Development


Iron supplementation during pregnancy is vital to prevent iron deficiency anaemia and ensure the health of both mother and baby. In Sri Lanka, all pregnant women receive iron supplementation to support maternal and child health.

Understanding Iron Deficiency Anaemia in Pregnancy 

During pregnancy, women require more iron to support the growth and development of their baby and placenta, as well as to maintain their own increased blood volume. When iron levels are insufficient, iron deficiency anaemia can occur, leading to risks such as preterm birth, low birth weight, and infants born small for gestational age. In addition, Iron deficiency increases the risk of complications during labour and delivery like excessive bleeding. 

Benefits of Iron Supplementation in Pregnancy 

Iron supplementation offers several benefits during pregnancy. It significantly reduces the risk of maternal anaemia and iron deficiency, ensuring healthier outcomes for both mother and baby. Moreover, children born to mothers who received iron supplementation during pregnancy exhibit higher cognitive scores at the age of seven, highlighting the long-term benefits of maternal iron supplementation. Iron also plays a crucial role in fetal brain development, being involved in the synthesis of neurotransmitters and the myelination of neurons.

The World Health Organization recommends daily iron and folic acid supplementation for pregnant women, typically between 30-60 mg of elemental iron per day. To meet these requirements, pregnant women should consume a diet rich in iron, including foods such as red meat, fish, poultry, beans, lentils, and fortified cereals. It is crucial to highlight that there are two types of iron sources: heme (found in animal products) and non-heme (found in plant-based sources). Vitamin C can enhance the absorption of non-heme iron, so consuming vitamin C-rich foods or supplements alongside iron sources can be beneficial.

Factors Affecting Iron Absorption 

Certain substances can inhibit iron absorption. Phytates, calcium, and polyphenols (found in tea, coffee, and some vegetables) can negatively impact iron absorption. To maximise iron uptake, consider taking iron supplements with a source of vitamin C, such as a glass of orange juice or a vitamin C supplement. Additionally, avoid consuming calcium-rich foods or beverages, like milk or cheese, within an hour of taking an iron supplement.

Reducing Postpartum Depression 

Risk Iron supplementation during pregnancy may also help reduce the risk of postpartum depression. Low iron levels have been linked to fatigue and depression, which can be especially concerning after childbirth. By maintaining adequate iron levels during pregnancy, new mothers can potentially reduce the risk of postpartum depression and its associated challenges.
