Discovery and Innovation
The story of transfer factors and
For more than a decade, 4Life® (the immune system
company) has led the industry in immune system discovery and
innovation. Where did it all begin? With the revolutionary molecules
in your own body.
In 1996, 4Life Chief Executive Officer David Lisonbee came across
a patent for the extraction of transfer factors. Transfer factors
are molecules found within the immune systems of all mammals and
birds. Dubbed “the memory molecules,” transfer factors serve as
important components of the immune system throughout your entire
In 1998, 4Life licensed the patent to extract transfer factors
from cow colostrum. In the years that followed, 4Life launched new
products, stabilized transfer factors in liquid form, patented the
extraction of transfer factors from chicken egg yolks, and combined
our two sources for a truly synergistic formula.
Scientists have known that smaller molecules than transfer
factors existed within colostrum, but they never determined if they
had any immune activity. In 2007, David Lisonbee and the 4Life
Research and Development team isolated these nanofraction molecules,
tested them, and determined their potential to support the immune
Nanofractions are low-weight molecules found in the immune
systems of certain mammals and birds. They function as part of the
“command and control” network of the immune system.
Transfer factors and nanofractions transfer immune memory,
knowledge, and wisdom from one entity to another. The two most
abundant and safest sources for transfer factors and nanofractions
are cow colostrum and chicken egg yolks. Because these molecules
aren’t species-specific, we can benefit from the knowledge gained
by these animals during their lifetimes by transferring that
knowledge from their immune cells to ours.
