Detailed explanation-1: -The most common forms of neural tube defects are spina bifida and anencephaly. Folate deficiency increases the risk of neural tube defects, and inadequate concentrations of folate in a pregnant woman can therefore lead to the development of a fetus with congenital defects and malformations.

Detailed explanation-2: -A number of studies showed that taking folic acid before and during the first weeks of pregnancy helped to lower the chance of neural tube defects. CDC recommended that women who had a pregnancy affected by a neural tube defect consume folic acid before planning to become pregnant again.
