The responsibility of the future mother affects the development and health of the child even before conception itself. This responsibility not only includes regular check-ups and following the doctor's instructions but also educating oneself about the nutrition and necessary supplementation, which is crucial even in the prenatal stage. Many mothers and expectant mothers are not familiar with the nutrients they need to intake to ensure the fetus develops without potential complications and that the pregnancy has the most favorable outcome. Although proper nutrient intake is emphasized for all groups of people regardless of gender, age, and race, the emphasis on certain micronutrients is somewhat greater in pregnant women. The reason for this lies in the changes in the body that occur during fertilization and the fetus's need for adequate conditions in which it can develop. When it comes to micronutrient supplementation, it usually refers to iron, iodine, folic acid, and vitamins such as vitamin D, vitamin A, vitamin K, and vitamin E. A deficiency in these supplements affects many stages of development, such as the supply of oxygen to the fetus or the proper development of the nervous system. As a result of these developmental deficiencies, postnatal health issues may arise. Some severe conditions that can affect newborns include improper closure of the neural tube, which manifests as spina bifida or anencephaly. Additionally, a lack of micronutrients can also manifest in psychological disorders, with a high possibility of the child being born with cretinism. Poor outcomes can be avoided by consuming foods rich in these highlighted nutrients and by supplementing them before or during pregnancy
