During pregnancy there is an increased demand for certain vitamins and nutrients to ensure proper and adequate growth of the fetus. Prenatal vitamins generally contain higher levels of <a href="http://www.infantrisk.com/content/folic-acid-overview-metabolism-dosages-and-benefits-optimal-periconception-supplementation">folic acid</a>, iron, and calcium to meet this increased need. It is important to note that prenatal vitamins are not required when these nutrients are obtained through a healthy diet consisting of copious amounts of fruits and vegetables. However, if the patient chooses to supplement her diet with prenatal vitamins, she should first discuss her options with her attending physician to determine suitability. There are many different types of prenatal vitamins, and a physician will be able to discern which one is most appropriate for the patient.
