Our History

The Advancement of Immune System Science

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.


Studies and Patents

A Commitment to Excellence

Scientists around the world have conducted numerous studies to research the effectiveness of transfer factor molecules. 4Life scientists have continued this legacy by commissioning third-party studies and in-house scientific tests to understand just how well 4Life Transfer Factor® products interact with specific immune cells.

One test shows that 4Life Transfer Factor
® products can increase the immune system effectiveness of Natural Killer cells (important first responders) by up to 437%.

Another preliminary scientific test suggests that 4Life Transfer Factor® Tri-Factor® formula strengthens your immune system guard by increasing the number of protective salivary IgA antibodies by up to 73%. And, everyone tested experienced an increase!



4Life’s progressive science and pursuit of patent protection strengthen the business opportunity by giving 4Life distributors the exclusive right to market 4Life Transfer Factor products. Patents reinforce 4Life’s credibility in the wellness industry and demonstrate the company’s long-term commitment to exclusivity and stability.

Transferceutical Science

You want a strong and vibrant immune system. It’s why you exercise, get the right amount of sleep, eat healthy, and balance your stress levels. But even your best efforts sometimes leave you feeling rundown. What else can you do to keep your body feeling balanced and strong?

Science encompasses the research, technology, and innovation of products that educate your immune cells, supporting your immune system’s ability to recognize, respond to, and remember potential threats. This valuable education gives your body the extra edge to lead a healthy life.

Science is a journey that began with transfer factor memory molecules that form the basis of 4Life Transfer Factor® products. Innovations in transfer factor sources allowed 4Life to introduce Targeted Transfer Factor products to meet specific needs of the body. Never willing to settle, 4Life pursued a further understanding of immune cells with the discovery of immune activity in nanofraction molecules.

4Life has continued to expand its product base with a general health and wellness line, personal skincare, and weight management product line. Today, 4Life offers over 60 different products and multiple delivery choices.

Backed by scientists and doctors, 4Life Transferceutical products are patented, researched, and used by thousands of people around the world. You can experience a smarter immune system with 4Life Transfer Factor and discover just how good healthy can feel!

Simply Miraculous Molecules

4Life’s research of transfer factors initiated the study of smaller molecules with vast power for the immune system. Nanofraction molecules are tiny molecules within colostrum, a source of vital immune knowledge, with their own unique immune properties.

Through an exclusive patent-pending filtration method, 4Life concentrates the power of nanofraction molecules for its NanoFactor
® extract. NanoFactor® helps regulate immune cell reaction by supporting communication between cells, promoting stability and balance within the immune system, and prompting your body’s natural ability to stay on a healthy course. In short—NanoFactor® helps your immune system know when to step up the fight and when to stop and relax.

® offers support to immune cells by showing them:

•    When to act
•    How to act
•    When to rest

® extract is available in 4Life Tri-Factor® Formula products and 4Life® NanoFactor® Glutamine Prime®.

Transfer Factors

Vital Immune Knowledge

In the first critical days of life for humans and other mammals, a mother passes on vital immune knowledge through the first meal—colostrum—which contains transfer factor molecules. As nature’s first supplement, these memory molecules transfer immune experience to educate and prepare the newborn’s immune system to function in the world.

While vitamins and herbs provide nutrition to the immune system, transfer factors provide information so immune cells can do their jobs faster and more effectively. Research over the years has revealed that transfer factor molecules are abundant in nature. Through a patented filtration process, 4Life extracts transfer factors from cow colostrum and chicken egg yolks for the foundation of its Transferceutical

People of all ages can benefit from nature’s first supplement by borrowing immune memory from the strong, heroic immune systems of these two animals.

Transfer factors:
• Help immune cells quickly recognize                                                     invading germs or other potential threats
• Help the immune system respond more efficiently                                      after an invader has been identified
• Lend a hand in remembering how to tackle each                                 problem your immune system encounters, so your body                               knows exactly what to do the next time

4Life has gone further in promoting and researching the benefits of transfer factors than anyone else. This scientific innovation will undoubtedly continue.
