First discovered in 1949 by Dr. H. Sherwood Lawrence, transfer factors help immune cells quickly identify potential health threats, speed up the immune system’s response, and help the immune system remember the makeup of specific threats to handle them more quickly in the future.*

In 1998, 4Life Founder & Chairman of the Board David Lisonbee uncovered research about transfer factors and their benefits for the immune system.
