Iron deficiency is one of the most common mineral deficiencies in pregnant women and infants worldwide. Infants with iron deficiency anaemia test lower in cognitive, motor, social-emotional and neurophysiologic development than comparison group infants. Iron deficiency during gestation and lactation alters neurometabolism, neurotransmitters, myelination, and gene/protein profiles before and after iron repletion at weaning.
Randomised trials of iron supplementation show benefits which emphasises the importance of protecting the developing brain from iron deficiency.
