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.

Transfer Factors®

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 life.

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.

Nanofractions^TM

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 system.

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.
