A recent study has pointed out that newborns with lower levels of vitamin D may be prone to lung infection.
During the study, researchers in Netherlands evaluated vitamin D levels in 156 babies at birth by checking concentrations in their cord blood.
After a year, 18 babies were found to be victims of lower respiratory tract infection triggered by a respiratory syncytial virus (RSV). These babies may have had lower levels of Vitamin D which increased their susceptibility to infections.
Researchers said, "Especially during pregnancy, doses up to 4000 IU per day may be needed to maintain optimal maternal and neonatal health."
