Folic acid in early pregnancy?

Folic acid should be taken before pregnancy?? Folic acid should be taken before pregnancy. It is generally recommended to go to the hospital for a determination of methylenetetrahydrofolate reductase. If the methylenetetrahydrofolate reductase determination belongs to TT type or CT type, this situation should be doubled before pregnancy. At the same time, it is recommended to continue to eat folic acid after pregnancy. Under normal circumstances, you should also take folic acid until the third month of pregnancy. If it is a high risk of folic acid metabolism, you should take folic acid throughout pregnancy.
