• Fetal growth and brain development: Adequate iron levels help ensure proper development of the baby’s brain and nervous system.
• Reduces risks of preterm birth and low birth weight: Studies show that maintaining optimal iron levels lowers complications during delivery.

Adequate iron during pregnancy supports both the mother’s energy and the baby’s healthy development.

Benefits of Iron Supplements During Pregnancy

• Prevents fatigue and weakness by supporting healthy red blood cells.
• Boosts oxygen transport to tissues and the placenta.
