Transfer Factor E-XF™ is 4Life’s advanced transfer factor blend. Through a patented process exclusive to 4Life, transfer factors from both cow colostrum and chicken egg yolks are combined to produce synergistic immune-enhancing support.

They 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. NanoFactor helps immune cells know when to act, how to act, and when to rest.
While transfer factors and nanofraction molecules each provide effective immune system support on their own, intelligence and intuition are both needed for optimal immune system response.
4Life Transfer Factor Tri-Factor Formula brings together the intelligence of 4Life Transfer Factor and the intuition of NanoFactor to regulate, boost, and balance the immune system… according to what your body needs.
