Prenatal Vitamin D Intake May Reduce Risk Of Enamel Defects In Children

The New York Times reports, “Women who take large doses of vitamin D during pregnancy may be giving their children a lower risk of dental problems,” a “double-blinded clinical trial” suggests. Researchers randomly assigned 623 women into two groups and beginning on the “24th week of pregnancy, one group took two pills daily, one containing 400 units and the other 2,400 units of vitamin D,” while the other “took a 400 unit pill plus an identical-looking placebo.” Researchers “found that children of women who took the vitamin D regimen had a 47 percent lower rate of enamel defects in both permanent and baby teeth than those in the control group.” The study was published in JAMA Pediatrics.
