You can take folic acid in early pregnancy. You can take folic acid in the first two months of pregnancy and in the second three months of pregnancy to prevent neural tube abnormalities. Folic acid is available in 0.4 mg and 0.8 mg. If folic acid metabolism is normal, 0.4 mg of folic acid can be taken; if folic acid metabolism is abnormal, 0.8 mg of folic acid should be taken to prevent neural tube abnormalities. Some studies have shown that folic acid can also prevent anemia, prevent fetal malformations, and prevent gestational hypertension syndrome. Therefore, folic acid is important for women who are pregnant and can be taken not only during the first trimester but throughout pregnancy. The amount of folic acid and the time to take folic acid can be based on individual circumstances and the advice of a physician. If you have gastrointestinal discomfort after taking folic acid, you can choose to take it after meals. Foods with high folic acid content, such as meat and dark green vegetables, can be eaten more often.
