Whey Protein Isolate consists of lactoferrin, beta-lactoglobumin, alpha-lactoglobumin, glycomacropeptide and immunoglobulins. They demonstrate a range of immune-enhancing properties.
Whey protein isolate contains natural protein that is rich in cysteine, the crucial precursor for Glutathione synthesis.
Therefore, the adequate supply of Glutathione is a crucial factor in the maintenance of an effective immune system.
Selenium is needed for the proper functioning of the immune system.
Zinc deficiency, common in the elderly, is linked to impaired immune function.
