RESUMEN
Pregnancy presents a large number of metabolic adaptations and requirements of micro and macronutrients could be increased, which are not always covered by the diet making necessary to supplement some of them. The micronutrients are an important part of metabolic reactions and both; their deficiency as their excess could participate in damage to organs and tissues of the mother and the fetus. Actually the hypertension pregnant states (HPS) participate in the leading causes of death during pregnancy, making necessary the search for interventions to prevent or reduce the consequences.The oxidative stress levels are linked with the risk to develop HPS, which has created assumptions about the use of micronutrients with antioxidant power and its possible role as protectors in these pathologies, however, the information is still uncertain and the metabolic action of the use of micronutrients supplementation is not precisely known because some micronutrients have shown a protective effect on the development of HPS. It is necessary to evaluate the nutritional status before and during pregnancy, as well to realize more studies about it and strengthen public policies about the use of micronutrients during the pregnancy.
