It is possible to take folic acid tablets without pregnancy. Folic acid contains not only folic acid, but also rich in trace elements and nutrients, which are very beneficial to the body. From the perspective of eugenics, oral folic acid tablets should be taken 3 months before and 3 months after the planned pregnancy to effectively prevent fetal neural tube abnormalities. Nowadays, it is also clinically advisable for the male partner to take folic acid tablets together until after pregnancy, because folic acid tablets can improve the quality of sperm and effectively prevent fetal malformations, while folic acid, as a B vitamin, can also be supplemented by eating green vegetables or fruits, such as spinach, lettuce, chard, as well as bananas and pineapples.
