The correct answer is E. Vitamin A is an important vitamin for human reproduction and normal bodily functioning, and vitamin A deficiency is a problem throughout much of the world. In the U.S. and other developed nations, however, the overwhelming majority of women have sufficient stores of vitamin A in the liver. Thus, vitamin A supplementation during pregnancy is not needed or recommended for most women. In fact, vitamin A supplementation has been associated with birth defects, including cranial neural crest malformations. Most commonly used prenatal vitamins contain 5000 IU or less, and this is considered acceptable. Women should be instructed not to take any further supplementation than this. The only exception to this rule is for women who may be vitamin A deficient because of strict vegetarianism or because they are recent emigrants from countries in which vitamin A deficiency is endemic. Recent studies have suggested that vitamin A supplementation with as little as 10,000 IU (choice A) per day may cause birth defects. Therefore, this amount of supplementation should be avoided. The probable teratogenic dose of vitamin A, notwithstanding the abovementioned study, is 25,000 IU (choice B) to 50,000 IU (choice C). Patients should therefore be instructed to avoid these levels. 100,000 IU (choice D) would certainly not be recommended.
