4Life Discovery of Plant-Based Transfer Factor & Launch of MAX

4Life launched in 1998 with a focus on immune system supplementation. Its flagship product included an ingredient called transfer factor. Transfer factors were first discovered by Dr. H. Sherwood Lawrence, Head of Immunology at New York University (NYU) in the 1940s. They are immune-regulating peptides—protein molecules that help the immune system recognize, remember, and respond to potential threats.
Transfer factors are “transferred” from the mother in mammal colostrum and avian yolk—which have been the traditional sources of these protein peptides for 4Life products until the company discovered the same bioactivity markers… in plants.
Over the last three decades, 4Life has expanded with offices in twenty-five markets worldwide. It manufactures a line of immune system nutraceuticals at company-owned, NSF® certified plants in the state of Utah. The company has amassed more than 80 international patents and is BBB Accredited with an A+ rating for customer satisfaction.
