Can women get too much folic acid?
Unless their doctor advises them to take more, most women should limit the amount they take to 1,000 mcg a day. However, some women need more folic acid, especially if they are trying to get pregnant. For example, women who have had a previous pregnancy affected by birth defects of the brain and spine and women with sickle cell disease should be sure to talk with their doctors about the need for more folic acid.
