Transfer factors are "smart" messenger molecules, found in the bodies of all mammals and birds, that can transfer critical immune information to cells. Transfer factors provide intelligence to the immune system, supporting its ability to recognize and respond quickly and effectively. Because their basic structure is identical, they work equally well across species barriers — from animal to person or animal to animal.
   
  How were Transfer Factors Discovered?  
  In 1949, Dr. H. Sherwood Lawrence, distinguished immunologist at New York University, determined that an immune response could be transferred from a donor to a recipient — through a white blood cell extract. He concluded that the extract contained a factor capable of transferring the donor's immunity information to the recipient and named the substance transfer factor.  
     
  Who is 4LIfe Research?  
 

4Life Research™ is a world-class research company that was formed in 1998 to bring pure Transfer Factor Classic™, their first and only product at the time, to market. The CEO, David Lisonbee, had researched nutrition, food supplements & the immune system for many years & was a highly successful businessman. When he came across transfer factor in the medical literature, it changed his destiny.

4Life has a Research and Development Department that is second to none, led by CSO Calvin McCausland, PhD - the first American Scientist to be invited into the membership of the Russian Academy of Medical and Technical Sciences. 4Life's solid business model is based upon integrity and the foundation of Science, Success, and Service to the people of the
world. The company is in its10th year, continues to garner honors & media attention for their product uniqueness, their outstanding leadership, and their humanitarian emphasis.

  What are Nanofractions?  
  Nanofractions are low-weight molecules also found in the bodies of mammals and birds. They possess natural intuition and function as part of the complex "command and control" network of the immune system. Nanofraction molecules also ensure the appropriate immune response for each situation.  
     
  How was the power of Nanofractions first discovered?  
  Scientists have known for quite some time that smaller molecules than transfer factors existed within colostrum, but they never determined if these molecules provide any immune system support. Ever the pioneer, David Lisonbee, CEO of 4Life, worked with the 4Life Research and Development team to harness these molecules, isolate them, test them, and determine their potential to support the immune system. In 2007, 4Life scientists extracted these tiny molecules, and determined that they provide incredible fine-tuning power for the immune system.  
     
  What are the advantages of using chicken egg yolks or cow colostrum as a source of Transfer Factors and Nanofractions?  
  Chickens and cows live outside, where they contend with the challenges of varying weather conditions, eating from the ground, and communal living. This leaves them exposed to a variety of germs, which their immune systems must battle in order to stay healthy. Therefore, the hardy nature of their immune systems make cows and chickens ideal donors for transfer factors and nanofractions. Both of these immune messaging molecules can be transferred safely to humans, making cow colostrum and chicken egg yolk excellent sources for immune system support.  
     
  Is there scientific validation for Transfer Factors and Nanofractions?  
  Yes. In the 50 years since Dr. Lawrence's pioneering work on transfer factors, an estimated $40 million has been spent researching transfer factors and hundreds of scientific papers have been published documenting their effectiveness.  
     
  Are Transfer Factors and Nanofactions safe?  
  Yes. Transfer factors and nanofractions are in fact designed BY the immune system FOR the immune system so they are safe and effective for people of all ages. 4Life's extraction processes remove common allergens from egg and colostrum sources. And, any remaining lactose in colostrum-derived transfer factors and nanofractions is far below the amounts that typically cause reactions. (As a precaution, people with egg yolk allergies should check with their physician before taking 4Life Products with Transfer Factor E-XF™ or use the Transfer Factor Classic product which contains no egg extracted transfer factor.)  
     
  What is Transfer Factor E-XF?
Home
  Developed exclusively by 4Life using patented and patent-pending technology, Transfer Factor E-XF combines transfer factors from cow colostrum and chicken egg yolks to provide powerful, synergistic intelligence for the immune system.  
     
  What is Nanofactor extract?  
  NanoFactor extract is 4Life's patent-pending concentrate of nanofractions. Nanofractions provide essential intuition to the immune system so it knows when to act, how to act, and when to rest. Both intelligence and intuition are needed to keep you in healthy balance, resulting in a wiser, more fine-tuned immune system, and a more accurate level of immune response.  
  4Life Transfer Factor® Tri-Factor™ Formula brings together the intelligence of Transfer Factor E-XF and the intuitions of NanoFactor to regulate, boost, and balance, according to what your body needs. Tri-Factor Formula is found in select 4Life Transfer Factor® products, including:  
  4Life Transfer Factor® Tri-Factor Formula  
  4Life Transfer Factor Plus® Tri-Factor Formula  
  4Life Transfer Factor Rio Vida® Tri-Factor Formula  
  4Life RiteStart for Men® and RiteStart® for Women with Tri-Factor Formula  
     
  How does Tri-Factor formula work?  
  With Tri-Factor Formula, smart becomes wise. No matter what your body needs, Tri-Factor Formula delivers. Studies show that the enhanced Plus formula can boost Natural Killer cell function (first-line defenders) by as much as 437 percent (see Research). It can also fortify the function of T-cells (immune system modulators) to help your body stay in balance. Tri-Factor Formula truly is the ultimate in immune system support.  
     
  What is 4Life Transfer Factor RioVida™ Tri-Factor Formula?  
  RioVida is the only juice beverage in the world that provides the benefits of 4Life Transfer Factor Tri-Factor Formula. It also contains a blend of antioxidant rich fruits and berries, including açaí berry from Brazil, pomegranates, blueberries, elderberries, and grapes, making it a delicious source of support for overall wellness and vitality. Tri-Factor Formula in liquid form also offers a convenient delivery system for individuals who cannot swallow capsules.  
     
  How much Transfer Factor should I take?  
  Follow the recommended guidelines on the bottles for general health maintenance. If, however, you are struggling with chronic health issues, maximize your immune system by gradually working up to 3 X that amount. If you have an acute (sudden) illness, mobilize your immune system more quickly by tripling the amount immediately until your immune system is
winning the fight, then return to the maintenance amount.
 
     
  How much can children safely take?  
 

Children under 12 can take1/3rd to 1/2 the adult amount - or more as needed. It is a FOOD SUPPLEMENT, safe & nontoxic in any amount - but no need to waste. Very young children and adults with swallowing problems can take either the TF Classic (200mg) or the TF TriFactor (300mg) in juice, pudding, etc, by opening the capsules and sprinkling the amount needed. There are also 200 mg chewables for older children and adults.
