A new study is fighting an old myth that vitamin D can cause birth defects. In a randomized controlled trial, they assigned 494 pregnant women already at 12 to 16 weeks to 400, 2,000, or 4,000 IU of vitamin D per day until delivery.
They then conducted logistic regression analysis to see the influence of vitamin D in terms of gestational diabetes, infections, preterm labor and birth, and preeclampsia. What they found was not only earth shattering in relatino to the myth, they found that those who took the highest doses had half the risk of co-morbidities than the control group.
The study was presented at the Pediatric Academic Societies yearly meeting in Vancouver, Canada. Lead researcher: Carol L. Wagner, MD, of the Medical University of South Carolina, in Charleston.
