Why folic acid matters before and during pregnancy Folate is a B vitamin needed for DNA synthesis, cell division, and red blood cell production. In pregnancy, these functions become especially important because the embryo, placenta, uterus, and maternal blood volume…

Why protein matters in pregnancy Protein provides amino acids, which are required for maternal tissue expansion and fetal growth. During pregnancy, the body uses amino acids to build and remodel tissues, support enzymes and hormones, maintain immune function, and contribute…
