Immune system support via nutritional modulation

Nutritional modulation of the immune system describes how various nutrients—including vitamins, minerals, amino acids, fatty acids, and functional foods—affect immune cell development, activation, and function. These effects may be mediated by direct impacts on immune cell metabolism, regulation of gene expression (e.g., via vitamin D or zinc-dependent transcriptional processes), and indirect modulation through the gut microbiota. Diets deficient in critical nutrients impair multiple aspects of innate and adaptive immune function, whereas optimized nutritional status supports effective immune responses and may influence susceptibility to infection, inflammation, and chronic disease[1][2][3][4]. However, nutritional modulation is not a discrete druggable target molecule or receptor but a broad, multi-factorial regulatory mechanism. This entry is not a canonical molecular target but a complex, multi-pathway physiological concept.
