Can lactoferrin really enhance immunity?

Lactoferrin can indeed enhance immunity. Lactoferrin is an important non-heme iron-binding protein in milk, with multiple biological functions. Main mechanisms by which lactoferrin enhances immunity: 1. Antibacterial and antiviral effects: Lactoferrin can inhibit the growth and reproduction of microorganisms by binding to their surfaces, thereby exerting antibacterial effects. 2. Immune regulation: Lactoferrin can bind to receptors on the surface of immune cells, activate immune cell functions, promote the proliferation and differentiation of immune cells, and regulate the cytokines produced by immune cells, thereby modulating the intensity and direction of immune responses. 3. Antioxidant effects: Lactoferrin can eliminate free radicals in the body, reduce oxidative stress-induced damage to immune cells, and protect cells and tissues.
