4Life History - The Advancement of Immune System Science

4Life Transfer Factor Singapore - The 4Life Transfer Factor® story is a story of scientific innovation, study, and advancement in the world of immune system products. Transfer factors were originally discovered by New York University researcher Dr. H. Sherwood Lawrence in 1949. Dr. Lawrence, an immunology pioneer, was highly credentialed in his field. Lawrence’s study of how immune system response could be transferred from one entity to another provided the groundwork for one of the most significant health discoveries of our time—transfer factors.

In the early 1990s, 4Life Founder and CEO David Lisonbee started a journey to better support his own health. He had become frustrated with the results of many natural products. During his pursuit, he came across transfer factor research. David discovered firsthand the value of these educational molecules as the foundation for immune system support and overall health.

Because of the success he encountered with his own health from transfer factors, David presented this information to his wife Bianca. They knew this was something that had the power to change the lives of thousands of people. In 1998, David and Bianca launched 4Life Research™ and introduced the first 4Life product: 4Life Transfer Factor® Classic.

The 4Life story began with an unparalleled commitment to innovation and support for unrivaled health. And it will undoubtedly continue with new products, studies, patents, and cutting-edge advancements.
