What makes this product unique?

• Transfer factors are molecules found within the bodies of all mammals and birds. They transfer immune intelligence and promote the immune system’s ability to recognize, respond to, and remember invaders seeking to threaten health. Transfer Factor XF is 4Life’s extract of transfer factors from cow colostrum.
• Nanofraction molecules possess natural intuition and function as part of the complex “command and control” network of the immune system. NanoFactor is 4Life’s patent-pending extract of nanofraction molecules from cow colostrum.
• In an independent study, 4Life Transfer Factor XF raised Natural Killer cell activity by 204 percent.* Natural Killer cells are on the front lines of your immune system.
• In an independent study, 4Life Transfer Factor increased production of protective IgA antibodies in the mouth by an average of 73 percent.† IgA antibodies reside on the surface of mucous membranes and bind themselves to potential immune system invaders.
