Immune system support via nutrient supplementation

"Immune system support via nutrient supplementation" refers to the broad role of dietary nutrients (vitamins, minerals, amino acids, fatty acids, probiotics, and prebiotics) in maintaining or enhancing immune system activity and balance. Numerous micronutrients, including vitamins C, D, E, A, zinc, selenium, and iron, as well as macronutrients like specific amino acids and fatty acids, are critical for the development, function, and regulation of both innate and adaptive immune responses. Deficiencies or excesses in these nutrients can impair immune cell behavior, antibody production, inflammation resolution, and defense against pathogens. Nutrient supplementation is primarily considered for populations at risk of deficiency or during times of increased immune demand, and does not directly act like a drug targeting a defined molecular entity but rather modulates numerous pathways systemically[1][2][4][6].
