Increases in NK Cell Activity Advances Immune System Function

Increase in Natural Killer Cell Activity

* Test results obtained from two independent NK cell studies. Original testing using 4Life Transfer Factor Classic bovine formula utilized a 4 hour activation time. Secondary blind study test results, conducted by Dr. Anatoli Varobiev, 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 colestrums 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.
