Folic acid is widely used in the prevention and treatment of folate deficiency, which can lead to anemia, particularly in pregnant women to reduce the risk of neural tube defects in developing fetuses. It is a key ingredient in prenatal vitamins and is often added to fortified foods like cereals and bread to ensure adequate intake. In medical settings, folic acid supplements are prescribed to individuals with certain conditions, such as malabsorption disorders or those undergoing treatments like methotrexate therapy, to mitigate side effects. Additionally, it plays a role in supporting healthy cell growth and function, making it beneficial for overall health maintenance.
