All interventionsMicronutrients are only needed in very small quantities but are essential for normal physiological function, growth and development. Deficiencies of micronutrients such as vitamin A, iron, iodine and folate are particularly common among during pregnancy, due to increased nutrient requirements of the mother and developing fetus. These deficiencies can negatively impact the health of the mother, her pregnancy, as well as the health of the newborn baby.
The most current evidence shows that giving multiple micronutrient supplements may have limited benefit and little harm on birth outcomes, however, the evidence on low birthweight and its component parts (preterm birth and SGA) is difficult to interpret.
