Folic acid and vitamin E are two very important nutrients for pregnant women. The role of folic acid is to promote the development of the baby’s nervous system, which is very important for preventing neural tube abnormalities and reducing the probability of neural tube malformations. Therefore, it is recommended to take folic acid during the preparation period and the first trimester of pregnancy, which also belongs to the category of eugenics. In addition, folic acid is also involved in the formation of ferritin and hemoglobin in the body, so folic acid supplementation is also useful for preventing anemia. Vitamin E has a role in protecting the fetus, also called tocopherol, if the body is deficient in vitamin E, it is easy to increase the probability of preterm miscarriage, so if a woman is preterm miscarriage, you can also take appropriate vitamin E supplements, so that it has a certain effect on the safe fetus. But simply rely on vitamin E to protect the fetus or not, but also need to cooperate with other birth control drugs.
