Insufficient supply of pregnant women with micronutrients leads to the development of a number of congenital malformations of the fetus. In order to study the multivitamin-mineral complexes application’s effect on pregnant women during pregnancy, and on intrauterine fetal growth and development. Was revealed that a deficiency of bioelements and vitamins in mothers is a common cause of intrauterine growth retardation, serious violations of organs and systems functioning. So, it is indicates integrated approach significance in the treatment of microelementosis in pregnant. Keywords: microelements, vitamins, newborns, intrauterine growth, pregnancy. Introduction The rational nutrition of a woman during pregnancy and during lactation determines both her own health and the full development and health of the child. A special role in this belongs to vitamins and minerals. The mother’s body during pregnancy is the only source of vitamins and other nutrients for the fetus, and mother’s milk during breastfeeding is the only source of these micronutrients for the baby [4]. Infant mortality, especially among children of the first 5 years of life, depends not only on the level of development of medicine and the quality of medical care [1]. A significant role in this is also played by non-medical factors such as environmental factors, adequate and rational nutrition, providing the child’s body with necessary vitamins and calories, as well as the ecological environment of the children. The human need for vitamins and minerals (physiological need) is an objective value that has developed during evolution and does not depend on our knowledge. Based on scientific data on the study of physiological needs, the recommended rate of intake (RRI) of vitamins and minerals is established [12]. They take into account the real micronutrient supply of our country’s population, but they are also fully consistent with global trends (Table 1) Table 1. : Recommended norms of consumption of vitamins and minerals for pregnant and lactating women Vitamins Women of childbearing age and pregnant (first half of pregnancy) pregnant (second half pregnancy) nursing (1-12 months) C mg 90 100 (+11%) 120 (+33%) B1 mg 1,5 1,7 (+13%) 1,8 (+20%) B2 mg 1,8 2,0 (+11%) 2,1 (+17%) B12, mcg 3,0 3,5 (+17%) 3,5 (+17%) Folate, mcg 400 600 (+50%) 500 (+25%) Pantothenic acid, 5,0 6,0 (+20%) 7,0 (+40%)
