Folic acid, also known as vitamin B9, is a water-soluble B vitamin that occurs naturally in many foods. It is essential for the production and maintenance of new cells. Folic acid plays a key role in many processes in the body, especially cell growth and DNA synthesis. It is widely used in pharmaceutical products for its ability to promote cell growth and division. Folic acid helps in the production of healthy red blood cells and prevents anemia. It is commonly added to many pharmaceutical products to support cell division and growth. Folic acid is heat and light sensitive, so pharmaceutical products containing folic acid are packaged and stored properly to maintain stability and potency.
