About

La lactoferrina es una glicoproteína fijadora de hierro que priva a los patógenos de este mineral ejerciendo efecto bacteriostático, modula las respuestas inmunitarias innata y adaptativa, potencia la actividad de células NK y neutrófilos, y apoya la función inmune de la barrera intestinal. Un metaanálisis demostró una reducción del 40-45% en las probabilidades de infecciones del tracto respiratorio.

How It Works

Iron-binding glycoprotein that sequesters iron from pathogens (bacteriostatic); modulates innate and adaptive immune responses; enhances NK cell and neutrophil activity; supports intestinal immune barrier function.
