Immunocal®: Immune Nutrient from Milk Protein

see Review article: 

One of the most important substances required by the immune system for optimal functioning is an amino acid complex called glutathione. However, supplementation is made difficult by the complexity of the body’s system for delivering glutathione to cells. Canadian researchers figured out a way to deliver glutathione effectively in the form of a natural milk protein supplement called Immunocal®, and early research suggests it has benefits for chronic fatigue syndrome, cancer, AIDS, hepatitis, and age-related conditions such as Alzheimer’s, Parkinson’s, and arteriosclerosis.
