Whey protein also has potent antioxidant activity because it is rich in the amino acids cysteine and methionine.

With a high concentration of these amino acids, immune function is enhanced through intracellular conversion to glutathione (GSH). Glutathione is the center piece of body antioxidant defense system that protects cells against free radical damage, pollution, toxins, and infection. In comparison to other protein sources, whey has the unique capacity to increase glutathione production that leads to improvements in body health condition

Highly effective antioxidant that protects the body’s cells against reactive oxygen species that are generated by immune cells to kill pathogens.

Studies have suggested Copper deficiency in the host can be linked to increased susceptibility to infection and improved immune response when the host is provided with a copper supplement
Vitamin A is known as an anti-inflammation vitamin because of its critical role in enhancing both, cellular immune responses and humoral immune processes.

Research suggests positive correlation between a deficiency of micronutrients and infectious diseases spread through the respiratory and digestive systems
