Scientists at the University of North Carolina have discovered that the micronutrient, called choline, is vital in helping babies in the womb develop parts of their brains linked to memory and recall.

In a study of the effects of choline on the brains of baby mice, those fed small doses of choline while in the womb had genetic differences to those given large amounts."
