Disclaimer: The following is meant for use as general nutrition educational content only. A woman, pregnant, breastfeeding, or trying to conceive, is strongly advised to discuss her need for vitamin A, or any specific nutrient, with her obstetrical/gynecological care provider. This is not meant to replace the advice of an individual’s qualified healthcare provider.
I recently wrote an article about the inclusion of vitamin A from food and/or vitamins during pregnancy. I discussed the role of vitamin A in reproduction and development, the current recommendations from "authoritative" bodies, and what type of foods can supply an adequate amount. While it is somewhat lengthy, I would encourage all women (and men) anticipating a pregnancy or currently expecting to read it in its entirety.
