What is the purpose of prenatal vitamins?

The purpose of prenatal vitamins is primarily to supplement nutrients that are essential for the health of both the mother and the developing fetus during pregnancy. These vitamins and minerals, such as folic acid, iron, calcium, and DHA, play a crucial role in preventing nutritional deficiencies that can affect fetal development and maternal health. For instance, folic acid is vital for reducing the risk of neural tube defects in the developing fetus, while iron supports increased blood volume and helps prevent anemia in pregnant women.

The other options do not accurately reflect the primary purpose of prenatal vitamins. While increasing maternal body weight can be an outcome of a healthy pregnancy, it is not the aim of taking prenatal vitamins. They do not specifically prevent morning sickness, which is a common discomfort experienced during pregnancy not directly linked to vitamin intake. Lastly, prenatal vitamins do not enhance fetal movement; instead, they ensure that the pregnancy progresses with the necessary nutrients needed for healthy growth and development.
