Can prenatal vitamin K1 (phylloquinone) supplementation replace prophylaxis at birth?
Based on the Normotest results, we suggest that vitamin K crosses the placenta and persists to activate the vitamin K-dependent coagulant factors until at least the fifth day of life. Thus, prenatal vitamin K1 administration may replace prophylaxis at birth.
