Lactoferrin - a protein classified to the group of transferrins, naturally occurring in glandular secretions, such as saliva or milk. Its especially high concentration is noted in colostrum and mother’s milk. It takes part in shaping non-specific immunity. It demonstrates a wide scope of immune functions, has antibacterial, antiviral, antifungal, anti-parasitic and anti-inflammatory properties.
The properties of lactoferrin are noticed not only in relation to body fluids, but also in case of its supplementation. Therefore, supplements with lactoferrin are used in order to improve immune functions of the organism. This protein is especially effective in the fight with viral infections.
Moreover, lactoferrin demonstrates the ability to chelate iron ions, which also demonstrates positive influence on the immune functions. It also stimulates phagocytosis and has immunotropic effect.
