Prenatal nutrient's unique proprietary formula provides 100% of the daily value of most of the essential vitamins and minerals for pregnant and lactating women. Nutritional requirements dramatically increase during pregnancy and when a woman is breastfeeding. Good nutrition and lifestyle habits promote normal weight gain in the growing fetus and positively influence the progress and outcome of the pregnancy. However, many nutritionists acknowledge it may be difficult for a woman to obtain the required extra amounts of essential vitamins and minerals. As such, a prenatal supplement is often recommended to ensure that both mother and baby get all the nutrients needed for optimal health such as folic acid, calcium, and iron.
