Transfer Factor Facts:
Scientific studies prove it: 4life Transfer Factor supplements offer the most powerful immune system support available.

"Test results obtained from an independent, unpublished in vitro experiment conducted at the Russian Academy of Medical Sciences, in Kashirskoe Shosse, Russia. The randomized and controlled in vitro study assessed the effects of 4Life Transfer Factor® Classic, 4Life Transfer Factor® Tri-Factor® Formula, or 4Life® Transfer Factor Plus® Tri-Factor® Formula, versus a positive control (Interleukin-2, or IL-2) on NK cell activity and effectiveness in destroying damaging cells. Blood was collected from healthy volunteers and then incubated for up to 48 hours. (REFERENCE: Kisielevsky MV & Khalturina EO. Unpublished observations)."

Transfer Factor was discovered by Dr. H. Sherwood Lawrence, a New York University immunologist, in 1949. 4Life Transfer Factor products have been in the market for more than 15 years and are certified and guaranteed.

Transfer factors aren’t vitamins, minerals or herbs—substances that add nutrients to the body. Transfer factors are molecules that actually transfer immune memory and knowledge from one immune system to another. Transfer factors provide intelligence to the immune system in three very important ways: transfer factor help immune cells identify invading germs and other problems more quickly, transfer factors help speed up the immune system’s response to an invader after it’s been identified and lend a hand in remembering the specific makeup of each germ your immune system encounters, so the next time it comes around, your body knows exactly what it is, and what to do.
By activating the NK - natural killer- cells, the immune system serves as a modulator that triggers our body's natural response and remembers potential health threats.
4life Transfer Factor is a daily use immune support natural product. Robust support for the immune system and the entire body is vital. Targeted Transfer Factor products provide specific support for different body systems, including the cardiovascular system, metabolic and endocrine systems, female and male reproductive health, urinary system and brain.
