Executive Summary
VITAMIN A "MODERATE" SUPPLEMENTATION DURING PREGNANCY DOES NOT RAISE RISK of birth defects, including neural tube defects, according to a study published in the July issue of the American Journal of Obstetrics and Gynecology. Based on data collected through telephone interviews with approximately 1,500 women, James Mills, MD, National Institute of Child Health & Human Development, et al., found "no association between periconceptional vitamin A exposure" through supplements, fortified cereals or organ meats at levels below 8,000-10,000 IU per day "and malformations in general, cranial neural crest defects or neural tube defects."
