Folic acid plays a role in the cell division process: being involved as a cofactor in the formation of DNA, it comes into play every time a cell divides. This function is of particular interest in rapidly regenerating tissues. Supplemental folate intake is especially important for women trying to conceive or who are already pregnant because it increases maternal folate levels. Low folate levels during pregnancy are a risk factor in the development of neural tube defects in the fetus. Folate also contributes to thenormal synthesis of amino acids and the growth of maternal tissue during pregnancy. Folate also helpsreduce tiredness and fatigue in all individuals , also supporting the physiologicalformation and maturation of blood cells. Folic acid supports the normalfunction of the immune systemandnormal homocysteine metabolism; many studies indicate that conditions with high blood homocysteine concentrations should be considered a possible cardiovascular risk factor. Folate also contributes to normal psychological function.
