Oral folic acid is recommended for pregnant women when they are preparing for pregnancy, up to the first trimester, to reduce the incidence of fetal neurovascular malformations. The need for folic acid after the third trimester varies from person to person, and a test for folic acid metabolism disorders can be done. If the test is normal, there is no need to take folic acid after the third trimester. If the test indicates that folic acid metabolism is impaired, the doctor will still recommend taking folic acid until full-term delivery, which is relatively safer. Now there are many multivitamins, which contain a variety of vitamins needed during pregnancy, you can take this one, it is also relatively simple, but also can supplement other nutrients needed during pregnancy.
