Instead, when
we consider the selective essential micronutrients during the
embryo-fetal development, the insufficient intake of some of
them is clearly associated with some malformation syndromes,
such as neural tube birth defects related to insufficient amounts
of folic acid and vitamins C, B6 and B12 [11,12]. The purpose
of this brief narrative review is to emphasize the importance
of nutrition before and during pregnancy, as the mother is
the source of all the molecular elements that help to regulate
growth and development of the embryo until birth.
