A pregnant woman’s diet does not differ much from that of a normal diet, but it must adapt to an increased need for some nutrients, such as folate, to guarantee the regular, healthy development of the central nervous system and more for the fetus.
Both national and international guidelines recommend supplementation with 400 micrograms (mcg) per day of active folic acid (5-MTHF) in women without specific risk factors in order to reach an optimal concentration for the prevention of pregnancy pathologies and birth defects related to folate deficiency at this particular stage of life.
Optimal supplementation should begin at least one month before conception to get your body in the best condition for the start of pregnancy. Folate is essential, especially in the very early stages of gestation, so supplementation is essential at least until the end of the first trimester (periconceptional period).
