When were transfer factors discovered?
In 1949, Dr. H. Sherwood Lawrence, a New York University immunologist, determined that an immune system response could be transferred from a donor to a recipient through a white blood cell extract. He concluded that these extracts contained a “factor” capable of transferring the donor’s immunity information to the recipient. Dr. Lawrence subsequently coined the term “transfer factor.”
In 1998, 4Life Founders David and Bianca Lisonbee licensed the patent to extract transfer factors from cow colostrum. The introduction of 4Life Transfer Factor®Classic opened the door to new immune system support products. 4Life’s commitment to transfer factor research has progressively raised the standard for modern-day immune system supplementation.

What are transfer factors?
Transfer factors are molecules that transfer immune system memory and knowledge from one entity to another. Transfer Factor science is ground-breaking innovation for immune system support.
How does 4Life Transfer Factor® support the immune system?
Transfer factors are some of the most unique molecules in your body. They carry important messages to immune system cells. Transfer factors help your immune system do three big things.
Recognize: 4Life Transfer Factor helps immune system cells quickly identify invading threats.
Respond: 4Life Transfer Factor helps speed up the immune system’s response to a potential threat after it’s been identified.
Remember: 4Life Transfer Factor helps your immune system remember the specific makeup of previously encountered threats, so your body knows how to combat those same threats again.
How is 4Life Transfer Factor different from other products?
4Life Transfer Factor is different from other immune system support products because it's not a vitamin, mineral, or herb. 4Life Transfer Factor is a molecule that educates your immune system and helps it stay active and balanced. 4Life Transfer Factor works with your immune system in a unique way. It teaches your immune system to recognize, respond to, and remember potential invaders. Looking beyond simple nutrition to providing vital information is a profound paradigm shift, and only 4Life Transfer Factor products leverage this innovative approach.*
Does 4Life have patents for their 4Life Transfer Factor products?
Yes. The extraction process for transfer factors from chicken egg yolk is protected by U.S. Patent 6,468,534. Exclusive combination techniques for transfer factors from cow colostrum and chicken egg yolk are protected by U.S. Patent 6,866,868.
