Vitamin C 

Vitamin C supports the immune system through antioxidant activity [1]; it also supports the body's defense system by enhancing the function and activity of white blood cells, as well as increasing the level of interferon, antibody response and thymus hormone secretion; in addition, it can maintain Healthy mast cells function and support the formation of lymphocytes.

Vitamin D

Vitamin D can support immune cell activity and maintain healthy cell metabolism. Clinical trials have found that vitamin D is involved in the regulation of certain important genes [2], which are related to immune function, stress response and DNA repair.

Zinc 

Zinc is a cofactor for more than 300 enzymes and is essential for a variety of physiological functions, including the regulation of innate and adaptive immune cell signal transduction [3]. The homeostasis of zinc is particularly important for cell maturation and cell differentiation. In addition, zinc supports the body's defense system by improving the functions of neutrophils, natural killer cells and T lymphocytes.
