First: the best time to supplement folic acid should be from 3 months before you are ready for pregnancy to the whole early pregnancy. When the fetus is in the mother, the brain development is the fastest. The early pregnancy (3-6 weeks) is the key period for the growth and development of the fetal central nervous system. At the end of the fourth week of gestation, the embryo formed primitive brain vesicles. Although at the eighth week of gestation, the height of the fetus was only about 3 cm and the weight only increased by more than 2 g, its brain cells proliferated rapidly and were most vulnerable to teratogenic factors. If folic acid is supplemented at this critical time, the risk of fetal neural tube can be reduced by 50% - 70%.
