I'm in forty two years, What milligram of Acid Folic I need to take before pregnancy?

    But I've heard most of women over 40 are taking more than 1000 mg, around 5000 mg everyday, it's still question for me
    The U.S. Preventive Services Task Force advises to take 0.4 to 0.8 milligram daily. But Nicholas Wald, the British researcher who demonstrated folic acid’s role in preventing NTDs, says that all women who are trying to conceive should take 5 milligrams daily, He says 0.4 milligram will prevent about 40 percent to 50 percent of neural-tube defects; 5 milligrams about 80 percent. If you opt to take 5 milligrams, you will need a prescription. Trying to get that much from multivitamins could lead to potentially toxic levels of other nutrients, such as vitamin A. Wald suggests continuing the higher dose for the first two to three months of pregnancy.
      Dear Elena Thank you so much for the useful information:)
