Folic acid is composed of pteridine, p-aminobenzoic acid and glutamic acid, which plays an important role in nucleic acid biosynthesis. Generally speaking, folic acid supplementation should be started three months before pregnancy and eaten until the third month of pregnancy. If necessary, pregnant women should even supplement folic acid throughout pregnancy.

Of course, if it is not enough to supplement folic acid only during pregnancy, other vitamins should be supplemented. You can choose a multivitamin tablet with a slightly better brand in the market. For example, Ailurvy multivitamin tablet belongs to Bayer in Germany and contains folic acid, 1 1 vitamins, 7 minerals and trace elements. Each tablet contains 0.8mg folic acid, which is twice as fast as 0.4mg folic acid to prevent baby birth defects. Moreover, Avril contains 60mg of iron, which is also in line with the daily iron supplement dose recommended by the World Health Organization during pregnancy. I have been eating from their family during pregnancy, and I think a scientifically matched multivitamin tablet is more convenient and convenient than a single folic acid tablet.
