(7) The Institute recommends against getting more than 1,000 micrograms per day of folic acid from supplements or fortified food; folate intake from food is not a concern. One main reason for the upper limit on folic acid is that getting too much folic acid can mask the signs of a vitamin B12 deficiency.
Mean dietary intakes of folate (including food folate and folic acid from fortified foods) range from 454 to 652 mcg DFE per day in U.S. adults of various ages and from 385 to 674 mcg DFE in children aged 1 to 18 years [ 16, 17 ].he FNB developed DFEs to reflect the higher bioavailability of folic acid than that of food folate. At least 85% of folic acid is estimated to be bioavailable when taken with food, whereas only about 50% of folate naturally present in food is bioavailable [ 2, 3 ].
