What is the primary purpose of prenatal vitamins?

The primary purpose of prenatal vitamins is to provide essential nutrients necessary for fetal growth and development, which supports a healthy pregnancy. These vitamins are specifically formulated to meet the increased nutritional demands of a pregnant individual, ensuring that both the mother and the developing fetus receive the necessary vitamins and minerals. For example, folic acid is a crucial component of prenatal vitamins, as it helps prevent neural tube defects in the developing fetus. Additionally, iron and calcium are important for the mother's increased blood volume and the development of the fetal skeleton, respectively.

While improving sleep, reducing pregnancy symptoms, and preventing gestational diabetes are important aspects of pregnancy health, they are not the primary aim of prenatal vitamins. Prenatal vitamins are intended to help meet the increased nutritional needs that arise during pregnancy, thereby supporting proper fetal development.
