What is a common indication for using prenatal vitamins?

Prenatal vitamins are specifically formulated to support the nutritional needs of pregnant individuals and their developing fetuses. These vitamins typically contain higher amounts of essential nutrients such as folic acid, iron, and calcium, which are crucial for fetal development and maternal health during pregnancy. Folic acid, for example, helps prevent neural tube defects in the developing baby. Therefore, their primary indication is to provide the necessary nutrients that help support a healthy pregnancy, making pregnancy support the correct answer.

While other options may suggest health benefits, they do not align with the primary clinical goal of prenatal vitamins, which is focused specifically on pregnant individuals and their unique nutritional requirements.
