Folic acid is widely used in the food and pharmaceutical industries due to its essential role in human health. It is commonly added to dietary supplements and fortified foods, such as cereals, bread, and pasta, to help prevent folate deficiency, which can lead to anemia and other health issues. In healthcare, it is prescribed to pregnant women to reduce the risk of neural tube defects in developing fetuses. Additionally, folic acid is used in the treatment of certain types of anemia and to support overall cell growth and DNA synthesis. Its applications extend to animal feed as well, where it is included to promote healthy growth and development in livestock.
