The vast majority of infants in the U.S. are not getting the vitamin D that they need, even if they are fed vitamin-enriched formula, a new study has found. Roughly 9 out of 10 breast-fed babies receive less vitamin D than experts recommend, according to the study, which was conducted by researchers at the U.S. Centers for Disease Control and Prevention. Among formula-fed babies, fewer than 37 percent consume the recommended amount.
