Lactoferrin is a glycoprotein found in milk and various secretory fluids, including those coating the mucous membranes of the respiratory, gastrointestinal, and urogenital tracts. Scientific studies have demonstrated that lactoferrin exhibits antimicrobial, antiviral, and anti-inflammatory properties, all of which contribute to mucosal defense. Lactoferrin binds iron, making it unavailable to pathogens, thereby inhibiting their growth. Furthermore, it can modulate the immune response, supporting the integrity and function of mucosal barriers. Research has shown that lactoferrin supplementation can reduce the incidence and severity of infections involving mucous membranes, such as respiratory and gastrointestinal tract infections, particularly in infants and immunocompromised individuals. In vitro and some in vivo studies suggest that lactoferrin enhances the growth and repair of epithelial cells that line the mucous membranes, contributing to their maintenance and recovery after injury or infection. However, while the mechanistic and preliminary clinical data are promising, large-scale, high-quality clinical trials in diverse populations are still somewhat limited. Thus, the evidence supporting lactoferrin’s use for mucus membrane health is moderate and based on a growing body of scientific literature rather than traditional or anecdotal use.
