Folic acid is essential for the synthesis of DNA and proteins and for the formation of hemoglobin, and it is important for the correct growth of the embryo. The presence of folic acid is essential to balance the levels of homocysteine, an amino acid associated with cardiovascular diseases and heart attacks. Due to its protective action on the tissues that will form the fetus, it is important for the prevention of congenital defects (diabetes, malformations, anemia).

Vitamin B12 in fact acts in combination with folic acid to allow perfect hematopoiesis. Yes therefore to combinations of foods containing vitamin B12 and folic acid outlined above.
