Use of 5-methyltetrahydrofolate in preparing a medicine or health-care food for preventing neonatal congenital heart disease in peri-pregnancy and/or pregnant women has an effect of preventing congenital heart disease. The prophylactic dosage of the 5-methyltetrahydrofolate can be greater than 1 mg. Compared with synthetic folic acid, high-dose use has no teratogenic effect. Thus the 5-methyltetrahydrofolate can prevent birth defects in a high dose and can be used for preventing neonatal congenital heart disease.
