Researchers have found that women who took 5,000 IU's of Vitamin D everyday during pregnancy were more likely to have an uncomplicated birth.
Whereas women taking less vitamin D than this were more likely to have a baby born early (before the due date) or to develop gestational diabetes, preeclampsia, or infections. Women taking less
vitamin D were also more likely to have a c-section.
New animal studies have shown Vitamin D to prevent autistic-like behaviors.
