Minerals are associated with all stages of growth and cellular differentiation. When gestation coincides with adolescence, the nutritional requirements for optimal development of the mother and fetus increase significantly. Although there are many studies on the function of micronutrients, little is known about their influence on pregnancy outcome. This work aimed to review studies that investigated the influence of copper, iron and zinc on pregnancy outcome, especially in teenagers, focusing on intercurrences such as low birth weight, preterm births, pre-eclampsia, miscarriages and other complications associated with teenage pregnancy. There are only a few studies on this topic and a need to promote them in developing countries, where high rates of micronutrientdeficiencies and intercurrences are common. The efficacy of mineral supplementation in reducing deficiency rates and improving maternal reserves has been demonstrated but data on potential benefits for the fetus are not very conclusive.
