Vitamin A may reduce the symptoms of illness during pregnancy, a new study suggests. Researchers at the Johns Hopkins School of Public Health, Baltimore and two establishments in Nepal assessed the impact of weekly vitamin A and ?-carotene supplementation on the prevalence of pregnancy and postpartum illness symptoms among 15,832 Nepali women in a placebo-controlled test. There was no impact of either supplement on morbidity rates reported up to 28 weeks of pregnancy, however at more than 28 weeks symptoms of nausea, faintness and night blindness were reduced with vitamin A, but not ?-carotene, supplementation. Full results of the study are published in the Journal of Nutrition. 2000;130:2675-2682.
