The formation of the neural tube is primarily regulated by Folic acid. This is a crucial process that occurs in the early development of an embryo, leading to the formation of the brain and spinal cord. Folic acid, or folate, is a type of B vitamin that plays an essential role in this process. It helps in the production and maintenance of new cells, which is especially important during periods of rapid cell division and growth such as pregnancy. A deficiency in folic acid during pregnancy can lead to neural tube defects in the baby. Therefore, it is recommended that women who are planning to become pregnant or are in the early stages of pregnancy take a folic acid supplement.
