In 1949, Dr. H. Sherwood Lawrence made a revolutionary discovery while studying tuberculosis. He determined that an immune response could be transferred from a donor to a recipient by injecting an extract of white blood cells (leukocytes) from a previously infected, now healthy, subject into a newly infected patient. He found that this extract contained a factor capable of transferring immunity. He named the substance "transfer factor." 

Dr. Lawrence's discovery came in the midst of the discovery and use of antibiotics. Transfer factors have been used throughout the antibiotic age in different regions of the world such as China, Poland, Italy and others, but never have been available commercially due to the lack of technology. 

In the fifty years since Lawrence's pioneering work, an estimated $40,000,000 has been spent on research resulting in over 3,000 published scientific papers documenting the benefits of transfer factors. The world's leading scientists and physicians have established the safety and remarkable immune system benefits of transfer factors. The processing methods that allow for large-scale extraction of transfer factors have only recently been perfected and a commercial product has only been available within the last few years. 


Transfer factors are tiny molecules found in colostrum which provide "immune knowledge" from a mother's immune system to her baby used in recognizing and fighting outside threats. By transferring information from cell to cell, transfer factors serve as "teachers" to the new cells, ensuring a strong immune system capable of surviving, even thriving, in its new environment.* Transfer factors are not species-specific and can therefore be extracted from any mammal and then be given to another mammal with the same efficacy. 

4Life's™ Transfer Factor™ naturally supports the body's immune system, communicating immune information more efficiently among the cells in the body, and ultimately enhancing the body's ability to withstand attacks on its health.* 


4Life™ Research is dedicated to the continued research and the potentials of transfer factors. Since the introduction of our flagship product Transfer Factor™, we have continued to provide for immune support by introducing Transfer Factor Plus™ in April of 1999 and it has been very well received. In April of 2000 4Life™ brought TF RenewAll™, TF Kids™ and Transfer Factor Plus™ Canine and Feline Formulas to the market. The 4Life™ Transfer Factor™ Family is changing lives in North America, New Zealand and Japan. Our hope and desire is for continued success in strengthening the immune system as we take Transfer Factor™ to the world!
