Interferons are a group of proteins that can stimulate various immune cells in the body. They tell your immune system that germs or foreign invaders are in your body, and then trigger your immune cells to fight those invaders.  

Because of this, interferons have been identified by scientists, including world-renowned immunologist Dr. Yasuhiko Kojima, as being critical for immune function. Dr. Kojima spent decades screening hundreds of botanicals to identify natural interferon boosters. The exclusive MACH® blend used in NutriFeron was created based on his work. This blend of nutrients has been shown in laboratory studies to naturally increase interferon levels.*†1
