Taking folic acid during pregnancy causing stomach pain may be due to irritation of the stomach by folic acid. Folic acid is primarily used to prevent fetal neural tube defects and should be taken during preconception and the first three months of pregnancy. To reduce stomach irritation while taking folic acid, you can try simple methods such as taking it after meals or consuming it together with food.
