VANCOUVER, British Columbia, May 3 (UPI) — Pregnant women should take 4,000 International Units of vitamin D daily, U.S. researchers suggest.
Study leader Dr. Carol Wagner of the Medical University of South Carolina in Charleston says taking vitamin D supplements during pregnancy is not only safe for both mother and baby, but may prevent infections and pre-term labor/births.
Findings of the randomized-controlled study were presented in Vancouver at the annual meeting of the Pediatric Academic Societies.
Wagner and colleagues randomly assigned 494 pregnant women at 12-16 weeks of gestation into three treatment groups receiving different amounts of vitamin D daily until delivery — 400 IU, 2,000 IU or 4,000 IU — and also evaluated them monthly to ensure safety.
“No adverse events related to vitamin D dosing were found in any of the three arms of the study,” Wagner says in a statement. “The spectacular part of the study was it showed women replete in vitamin D had lower rates of preterm labor and preterm birth, and lower rates of infection.”
Since the greatest effects were seen among women taking 4,000 IU of vitamin D per day, the researchers recommend this as the daily regimen for all pregnant women.
