"Transfer factors are small proteins that 'transfer' the ability to express cell-mediated immunity from immune donors to non-immune recipients."

Transfer factors are tiny protein molecules with intelligence. They were first discovered by an immunologist in 1949, and have been found to transfer information that makes the recipient's immune system work smarter, faster and more efficiently. By communicating immune information from cell to cell, transfer factors help alert the immune cells to what they ought to be doing.

Welcome to our 4LIfe TRANSFER FACTOR®
educational website. Transfer factor ("TF") is a
powerful and remarkable immune support
product that we believe can make a difference
for you and your loved ones. It is all natural,
science-based, safe and effective for all ages.
Whether at home or abroad ...
A strong, balanced and fine-tuned immune system is the best possible health insurance.



Designed by nature to educate a newborn's immune responses, transfer factor:

  • Gives your immune system a memory boost, reminding it of past health threats.
  • Boosts or balances immune response, depending on the need.
  • Educates new immune cells.
  • Delivers a genetically encoded plan of action.
  • Speeds up the recognition phase, enabling your body to respond more quickly to whatever it encounters.

"Transfer factors could be the most exciting discovery in immunology to date. As the 21st century unfolds, these tiny molecules will hold the key to health and well-being. If you are interested in keeping up with the latest technology in health maintenance, transfer factors should top your list of natural supplements for the 21st century."

4LIfe's Transfer Factor™ has been included in the Physician's Desk Reference for Nonprescription Drugs & Dietary Supplements since 2003.

Here is the main text, minus product listing, from the 2008 volume, pages 689-90:


DESCRIPTION: Transfer factors are small peptides of approximately 44 amino acids that “transfer” cell-modulated immunity from immune donors to non-immune recipients. 4Life Transfer Factor® products are derived from egg yolk and cow colostrum extracts that contain antigen information. NanoFactor™ concentrate contains molecules smaller than transfer factors, stimulating T-Cell activity and providing additional immune information to non-immune recipients. Combined, these compounds comprise the Tri-Factor Formula, which offers the broadest spectrum immune support available.

   NanoFactor Technology has several patents pending. Transfer Factor and NanoFactor educate the immune system to recognize self from non-self, thus supporting healthy immune system balance. Because they instruct the immune system to act appropriately, these compounds are effective in supporting normal inflammation response in the body, a key to healthy body system function. 4Life Transfer Factor Plus Tri-Factor Formula combines Transfer Factor E-XF™ and NanoFactor with a proprietary formulation of innate and adoptive immune system enhancers such as Inositol Hexaphosphate, Cordyceps, Beta Glucans, Maitake and Shiitake Mushrooms. These ingredients work together to trigger and enhance the various immune protective mechanisms of the body. Clinical studies show that 4Life Transfer Factor Plus Tri-Factor Formula can increase Natural Killer cell activity up to 437 percent above baseline*, and that NanoFactor stimulates T-Cell activity to improve the immune system’s ability to stay in balance. * Blind Independent study conducted by Dr. Anatoli Vorobiev, Head of Immunology at the Russian Academy of Medical Science.

SUMMARY OF RESEARCH: In 1949 transfer factors were discovered by Dr. H Sherwood Lawrence. Since that time, hundreds of studies have been completed involving the effect of transfer factors on various diseases. Due to studies conducted in Russia, the Russian Health Ministry has approved 4Life Transfer Factor Plus to be the first supplements used by doctors and hospitals in Russia. Many of these studies and papers can be accessed through PubMed or other clinical study portals. NanoFactor research is currently in the forefront of immune science. Scientists have long known that molecules, smaller than transfer factors, existed in colostrum extract but there was no evidence to suggest immune activity. Advanced technology in filtration and testing has enabled 4Life scientists to extract these molecules, test them, and determine their immune activity, specifically an increase in ATP among T-helper cells and cytotoxic T-cells.

RECOMMENDED DOSE: 600 mg. Tri-Factor Formula daily. If used in combination with other immune ingredients such as Transfer Factor PLUS Tri-Factor Formula, less may be taken. No toxicity level of Tri-Factor has been found.

  TF in Colostrum vs. Pure Transfer Factor Extract    

Although colostrum has many excellent health benefits, the lactose and specific antibodies contained in it can cause reactions in some people. Because these molecules are much larger than the transfer factor molecules, they are filtered out of the colostrum by 4Life®’s patented ultra-filtration process, leaving only the pure transfer factors and the even smaller NanoFactors™. Transfer factors have the ability to communicate immune intelligence from cell to cell. The NanoFactors™ have been found to enhance the balancing of the immune response.

Every effort has been made to stay within the guidelines of the DSHEA Act of 1999 which allows us to speak of a natural product in terms of Structure/Function (what it is and what it does in the body). We make no claims that this product - in and of itself - will prevent, treat, or cure any disease or health condition. The value of transfer factor lies in its unique ability to boost and/or balance the immune system as needed.  We encourage you to consult your healthcare practitioner on all matters of personal health.
