4Life’s in-house Research and Development team includes doctors and scientists who keep 4Life on the cutting edge of scientific advancement. Additionally, its Health Sciences Advisory Board (HSAB) assists in the development of new products and helps further research into 4Life Transfer Factor Science.
Members of the Advisory Board
 Robert W. Robertson, Jr., MD |
Dr. Robertson is the founding member of the Health Sciences Advisory Board and an active 4Life distributor. Following a lucrative career as the Director of Emergency Services at Western Baptist Hospital in Paducah, Kentucky, Dr. Robertson and his son Rob Robertson, III decided to start a nutritional supplement company. It was while conducting product research for their company that the two discovered the many benefits of transfer factors. Convinced of the importance of 4Life’s mission, they sold their company and became distributors.

As one of the founding members of the Health Sciences Advisory Board, Dr. Bennett is an active consultant to the 4Life Research and Development team. He holds a Doctorate in Comparative Pathology from the University of California, Davis where he worked for 25 years conducting research focused on the practical aspects of protecting food and water systems from microbes that degrade quality and pose threats to health and safety. Dr. Bennett has also done extensive research on the influence of transfer factors on antibody production and its development in immune modulations. More recently, he authored a book on the effects of inflammation and how it is modified by transfer factors and antioxidants. Dr. Bennett’s research on mammary immunity provided some of the first observations of the unique cellular immune attributes of colostrum, which led to the recognition of colostral transfer factors. |
