In 1949, Dr H. Sherwood Lawrence made a very significant discovery. In the process of studying tuberculosis, which was a major health threat at the time, he discovered an immune response could be transferred from a donor to a recipient through an injection of an extract of white blood cells.

Further investigation led him to conclude that this immune extract must contain “factors” that made it possible to transfer the donor’s immunity to the recipient. He called these molecules "transfer factors".

In 1998, 4Life’s innovative Co-founders, David and Bianca Lisonbee, licensed the only existing Transfer Factor™ patent at the time – securing 4Life®exclusive extraction rights and making Transfer Factor accessible and affordable.

In 1999, the effectiveness and safety of transfer factor supplementation was validated by scores of clinical studies worldwide. Scientists are just beginning to grasp the profound implications of transfer factor therapy in determining the health of not only present, but future generations.
