What is the purpose of prenatal vitamins?

The primary purpose of prenatal vitamins is to provide essential nutrients for both maternal and fetal health. These vitamins contain important components such as folic acid, iron, calcium, and DHA, which are critical during pregnancy. Folic acid, for instance, is vital for the prevention of neural tube defects in the developing fetus, while iron helps prevent anemia in the mother. By ensuring that both mother and baby receive these essential nutrients, prenatal vitamins support healthy fetal development and a safe pregnancy.

The other choices do not accurately capture the primary function of prenatal vitamins. While morning sickness is a common symptom during pregnancy, prenatal vitamins are not specifically designed to alleviate it. Weight gain is a natural part of pregnancy, but prenatal vitamins are not intended to facilitate this; rather, they support overall health and nutritional needs. Similarly, prenatal vitamins do not directly prevent preterm labor, even though proper nutrition can contribute to a healthier pregnancy overall.
