When is it better to eat folic acid during pregnancy?

Folic acid is important for fetal development, preventing neural tube defects and reducing the risk of fetal abnormalities. Taking folic acid at least one month before pregnancy and in the first trimester of pregnancy can reduce the risk of neural tube defects by 70%. Folic acid can also reduce the risk of other fetal defects, such as cleft lip and certain types of heart defects. But because everyone's physique is different, the dose of folic acid required is also different. Pregnant women are best to take it under the guidance of a doctor, which is more conducive to eugenics. Many foods also contain folic acid, such as broccoli, spinach, radish, vegetables, okra, asparagus, etc., which can be eaten more and supplemented with folic acid. However, it should be noted that taking folic acid for a long time may show some adverse symptoms, such as nausea, diarrhea, etc., so be sure to pay attention to the dosage.
