SUPLEMENTACIÓN CON COBRE ENTRE COMIDAS NO TIENE EFECTO SOBRE LA NUTRICIÓN DE HIERRO EN HOMBRES

Iron deficiency is prevalent in most of the developing world where it coexists with other micronutrient deficiencies such as copper. Combined supplementation with iron and copper is one of the strategies that can be used to improve the iron and copper status of a population. However, there is concer...
