Research leads on the potential of lactoferrin against Covid-19
Lactoferrin is a glycoprotein naturally present in human secretions (tears and saliva) and in breast milk that is known for its ability to regulate the immune system. It can be used to limit infections as an antimicrobial agent, stimulate the immune system, improve intestinal health, or prevent iron deficiency.
The antiviral effects of lactoferrin can directly interfere with the life cycle of many viruses. Lactoferrin acts on the binding process of adenoviruses, for example, inhibiting replication. It also interferes with infection by binding to structures in the viral envelope. We also know that lactoferrin can interfere with other viral particles in vitro.
Due to its multiple functions, scientists consider lactoferrin to be an ideal candidate in the fight against the SARS-CoV-2 coronavirus, the cause of Covid-19. The natural protein lactoferrin has been used for its virus-fighting and preventive properties for several years. Its antiviral properties are particularly promising for research on Covid-19 prevention and treatment. When associated with other agents, lactoferrin can mitigate symptoms of the illness and prevent transmission.
