Researchers Ikeda, M. et al from the National Cancer Institute in Japan report that bovine lactoferrin directly binds to the HCV and effectively prevented hepatitis C in cultured human hepatocytes cell lines. They report on experiments which show that Lactoferrin directly binds to HCV and not to the infected cells. Other research has confirmed that lactoferrin binds to HCV and a number of other viruses. Lactoferrin is also a natural component of human motherís milk which is also effective against HCV. Lactoferrin is available as an over-the-counter dietary supplement. Adult dosage levels are usually 1000 to 1500mg or more daily. No adverse effects have been reported.
