Whey protein is particularly rich in substrates for GSH synthesis. We suggest that whey protein may be exerting its effect on carcinogenesis by enhancing GSH concentration."

"PRP (proline rich polypeptides) activates an underactive immune system, helping it move into action against disease-causing organisms.
