Folic acid has no known toxic levels.
For example, if you were to eat a bowl of fully fortified cereal containing 400 micrograms of folic acid and take a 400-microgram folic acid supplement, and eat four to five foods rich in folate, women of reproductive age would not have a problem with too much folic acid. Even in very high amounts, folic acid is nontoxic. Nevertheless, it is recommended that women consume no more than 1,000 micrograms of synthetic folic acid a day. Larger amounts may hide the ability to quickly diagnose a rare vitamin B-12 deficiency. This condition primarily affects the elderly and can lead to neurological damage.
