Natural Killer cells, or NK cells, are important immune cells that provide a crucial first defense against infectious agents and diseased cells.  Once activated, NK cells react in two ways.  First, they promptly secrete chemical messenger proteins that modulate emerging immune cell responses.  Second, they become potent killers of infected cells.  Without Natural Kill cells, threatening conditions can get a strong foothold before additional immune responses are able to kick in.

Original test results showed that4Life Transfer Factor Classic boosted NK cell activity 103% above normal immune response without supplementation, more than two times higher than the next highest product.

Now, recent studies conducted by the Russian Academy of Medical Science validate these original results and report that 4Life Transfer Factor Advanced Formula boosts NK cell activity by 283 percent and 4Life Transfer Factor Plus Advanced Formula propels NK cell activity to a remarkable 437 percent above normal immune response! Studies also showed that 4Life Transfer Factor Classic increased NK cell activity by 204 percent when tested at a 48-hour activation time.

*Test results obtained from two independent NK cell studies. Original test using 4Life Transfer Factor Classic bovine formula utilized a four-hour activation time. Secondary blind study test results, conducted by Dr. Anatoli Vorobiev, head of Immunology, at the Russian Academy of Medical Science, used 4Life Transfer Factor Advanced Formula (Transfer Factor E-XF proprietary blend of both cow colostrums and egg yolk sources) and a 48-hour activation time. Comparison of activation times demonstrated that the longer activation time (48 hours) using the 4Life Classic and Advanced Formulas promoted a significantly greater percentage increase of NK cell response. Samples were tested for maximum time of effectiveness.

W ith two products?Life Transfer Factor Classic and 4Life Transfer Factor Plus—that already set new and higher standards in immune system support—providing boosts in Natural Killer (NK) cell activity of 103 and 248 percent—how did 4Life think of trying to improve them? It started with a dedication to the long-term pursuit of transfer factor research, which led to the discovery of eggs as another viable source for transfer factors. A commitment to remain the leader in transfer factor technology and to provide the highest quality, most effective products for good health further drove 4Life to be even better. And finally, it came from the belief that one of the best ways to improve 4Life Transfer Factor was to broaden the spectrum of support by combining safe and effective sources of transfer factors.

4Life researchers and scientists developed the Transfer Factor E-XF?proprietary blend in an effort to further maximize immune system support using transfer factor molecules. Transfer factors were taken from both the cow and chicken sources and combined in hopes of sparking a synergistic–effect which was definitely achieved.

4Life Transfer Factor Advanced Formula and 4Life Transfer Factor Plus Advanced Formula both feature the scientifically proven Transfer Factor E-XF proprietary blend. Developed exclusively by 4Life using patented and patent-pending technology, the E-XF blend calls upon the knowledge of two sources, providing an enhanced combined effect of transfer factors from both cow colostrum and chicken eggs. Research shows that the immune building effects of this transfer factor blend are more effective than that of colostrum or egg sources alone.

In an effort to determine how powerful the 4Life Transfer Factor Advanced formulas are, researchers Calvin McCausland, Ph.D and Emma Oganova, Ph.D, M.D. designed a study to test NK cell activity. Dr. Anatoli Vorobiev at the Russian Academy of Medical Science directed his team in the independent testing. Using blinded cytotoxicity testing, cancerous cells were combined with NK cells from humans and divided into groups of NK cells activated with transfer factors and groups of unactivated NK cells.

Samples containing several different blends of transfer factors sourced from cow colostrum and egg yolks were incubated with the NK cells for various time periods, in order to identify the most potent blend ratio and the optimal activation time of NK cells to provide maximum health benefits. Comparison of times demonstrated that the activation time of 48 hours promoted the greatest NK cell response.

Results of this study conclusively demonstrated the ability of 4Life Transfer Factor Advanced Formula to boost NK cell activity by 283 percent and of 4Life Transfer Factor Plus Advanced Formula to propel NK cell activity to a remarkable 437 percent above normal immune response (a response established as a baseline from this study). They also showed that 4Life Transfer Factor Classic increased NK cell activity by 204 percent when tested at a 48-hour activation time. Further, results from this scientific experiment showed that NK cells activated with 4Life Transfer Factor Plus Advanced Formula killed 97 percent of cancerous cells, which exceeded the Interleukin-2 (IL2) activation kill rate of 88% during the same time period.

The Russian scientists who conducted this study found the results to be exceptional and requested further information so their results could be published in professional journals. One scientist stated: “The 4Life sample [4Life Transfer Factor Plus Advanced Formula] activated NK cell activity more than the Interleukin-2 (IL2) drug used as the standard. Here, we now refer to your sample as the Golden Interleukin,?said Dr. Kisielevsky, Russian Academy of Medical Sciences.

These outstanding test results are certain to be reflected in human health through an increase in immune effectiveness, leading to improved overall health. People around the world can be confident in the ability of 4Life Transfer Factor Advanced Formula and 4Life Transfer Factor Plus Advanced Formula to more effectively modulate immune system function, making it more response “able?and to provide broad-spectrum support that is unmatched in any other health supplement today.
