Numerous studies have pointed out the clear connection between a well-functioning immune system and a sufficient daily intake of multiple specific micronutrients, including vitamins A, D, C, E, B6, and B12, folate, zinc, iron, copper, and selenium, which often play synergistic roles. Micronutrient deficiencies frequently occur in the human body, and even marginal deficiencies may impair immunity. Available evidence indicates that supplementation with multiple micronutrients with immune-supporting roles may optimize immune function and reduce the risk of infection. Micronutrients are relatively low-cost and readily available. Thus, they have the potential to reduce the global burden of infections. More details can be found in the review article.
