A suitable intake of vitamins and minerals both during preconceptional period and pregnancy is essential in reducing the incidence of adverse maternal and perinatal outcomes. This is more evident in developing countries, particularly during periods of famine, when women suffer from an inadequate intake of vitamins and minerals. Even in developed countries, however, most women's diet does not meet their increased needs for micronutrients. The association of different micronutrients in a single multivitamin preparation is consequently a useful, easy to take solution and with a good cost/benefit ratio, and can prevent some important obstetrics pathologies, as preterm delivery, fetal growth restriction and preeclampsia.
