Immune system modulation via micronutrient supplementation

Immune system modulation via micronutrient supplementation" refers to the collective influence of essential vitamins and minerals—such as vitamins A, D, C, E, B6, B12, folate, zinc, iron, copper, and selenium—on the function of the immune system at multiple levels, including innate and adaptive responses. These micronutrients support immune cell development and activity, maintain the function of physical barriers, modulate the production of cytokines, and possess antioxidant effects. Evidence indicates that proper supplementation in deficient populations may reduce the risk and severity of infections and modulate inflammatory responses, though clinical outcomes are inconsistent and not attributable to a single molecular target[1][2][3][4].
