the risk of too much folic acid is low. but as with any vitamin it is possible to consume too much folic acid if you combine supplements with food. adults should not get more than 1000 micrograms of folic acid per day. to put it into perspective a folic acid supplement or multivitamin usually has about 400 micrograms. other than breakfast cereals that are fortified with 100% of your folic acid needs (400 micrograms per day) most foods have relatively little folic acid content. for example we often recommend leafy green vegetables as a good source of folic acid. but frozen spinach which has the most folic acid has only 115 micrograms in a 1/2 cup. my point is that even if you take a folic acid supplement you still have plenty of room to enjoy foods rich in folic acid without the risk of over-consumption.
