Preparation for pregnancy requires a supplement of 400 to 1200 mg/day of folic acid as prescribed by the doctor.
Folic acid can prevent fetal neural tube malformations, and the amount of folic acid needed during preparation for pregnancy should be adjusted according to the mother’s ability to metabolize and utilize folic acid.
The normal folic acid requirement during pregnancy preparation is 400 mg/day, but if the mother has a moderate folic acid metabolism and utilization disorder, the folic acid dosage needs to be increased, which can be raised to 800 mg/day.
If the mother has a severe folic acid metabolic utilization disorder, the folic acid dosage needs to be strengthened even more and can be raised to 1,200 mg per day.
The utilization of folic acid can be detected by blood tests, and the specific dosage of the drug should be taken under the supervision of a doctor.
