What is the primary purpose of prenatal vitamins?

The primary purpose of prenatal vitamins is to provide essential nutrients that are crucial for fetal development. During pregnancy, the demand for certain vitamins and minerals increases significantly to support the growth and development of the fetus. Key nutrients found in prenatal vitamins include folic acid, which is vital for preventing neural tube defects; iron, which supports increased blood volume and oxygen transport; and calcium, which aids in the development of the baby's bones and teeth.

While some prenatal vitamins may have additional benefits that could help with aspects such as morning sickness or maternal energy levels, that is not their primary function. The main goal of these supplements is to ensure that the mother and developing baby receive the appropriate nutrients necessary for a healthy pregnancy.
