From the article:
"About 600 women took part in the trial which included similar numbers of African Americans, Hispanic Americans and whites. Premature babies born to women taking high doses of vitamin D were reduced by half at both 32 and 37 weeks, and there were also fewer babies who were born “small for dates” — that is smaller than would be expected considering the length of time spent in the womb."
"The women had a 25 per cent reduction in infections, particularly respiratory infections such as colds and flu as well as fewer infections of the vagina and the gums. The “core morbidities of pregnancy” were also reduced by 30 per cent in the women who took the high-dose vitamin D. These included diabetes, raised blood pressure, and pre-eclampsia, an increase in blood pressure and fluid which may, if untreated, cause the death of the mother and/or the baby. Babies getting most vitamin D after birth suffered from fewer colds and less eczema."
"The Charleston team is running another trial in breastfeeding women who are taking 6,400 IUs per day, a dose 16 times the amount of vitamin D recommended in the UK. This high dose enables women to make breast milk which has sufficient vitamin D for the baby’s needs, 400 IUs per day."
