Whey protein contains sialic acid (also known as N-Acetylneuraminic acid). Since many external pathogens (such as certain bacteria and viruses) identify host cells, the sialic acid glycopeptides found in whey protein can be beneficial. Sialylglycopeptide have a strong binding affinity for such harmful factors. By binding to these pathogens, they can help prevent infection and strengthen the body’s own natural defenses.
