About

Lactoferrin is an iron-binding glycoprotein that sequesters iron from pathogens (bacteriostatic), modulates innate and adaptive immune responses, enhances NK cell and neutrophil activity, and supports intestinal immune barrier function. A meta-analysis showed 40-45% reduced odds of respiratory tract infections.
