The Recommended Daily Allowances (RDA) for many vitamins and minerals is higher for pregnant women or women of childbearing age. The main nutrients are folate, iron, calcium, vitamin D, and docosahexaenoic acid (DHA). Folic acid is the form of folate that is found in supplements, and it is critical for the development of the baby’s neural tube. Before pregnancy, women need 400 micrograms per day. During pregnancy and when breastfeeding, women need 600 micrograms per day from foods or vitamins. During pregnancy, a woman’s blood volume increases so additional iron is essential to support the mom’s health and the baby’s development. Calcium during pregnancy can reduce a woman’s risk of preeclampsia, a serious medical condition that causes a sudden increase in blood pressure. Calcium is also necessary to build up the baby's bones and teeth, and calcium intake is prioritized to the baby so it is essential to consume an adequate amount for yourself and your baby.
