Vitamin C is an essential micronutrient that supports the immune system by providing antioxidant activity against reactive oxygen species. It also supports the body’s defense system by enhancing white blood cell function and activity, as well as promoting interferon levels, antibody responses, and secretion of thymic hormones.

Vitamin D provides general cellular support, in part by supporting immune cell activity, and maintaining healthy cell metabolism. In a clinical trial, Vitamin D supplementation was shown to support Vitamin D-regulated genes associated with immune function, response to stress, and DNA repair.

Zinc is a cofactor for over 300 enzymes and is essential for a wide range of physiological functions. The homeostasis of zinc is particularly important for proper functioning of immune cells. In addition, zinc supports the body’s defense system by promoting healthy neutrophil, natural killer cell, and T-lymphocyte function.
