4Life: The Immune System Company
Most people don’t give their immune systems a second thought, but here at 4Life (the immune system company) it’s a regular topic of conversation. Every minute of every day, your immune system is hard at work behind the scenes. If it’s revved up and ready for daily challenges, every other body system functions better. At 4Life, we offer innovative products that provide top-notch immune system support.
Our in-house Research and Development team is always in perpetual motion, exploring new and innovative ways to support wellness through the immune system. And if that weren’t enough, 4Life also has a Health Sciences Advisory Board, made up of outstanding physicians, biochemists, immunity experts, nutritionists, and formulators.

Transfer Factor - the key to a perfect day.
The biggest key to overall immune system health is balance-boosting when needed and calming down when needed. Almost all immune system products on the market today (vitamins, minerals, and herbs) have one thing in common: they provide temporary nutrition. However, the best long-term solution to an active, balanced immune response is information.
The way that 4Life Transfer Factor works with your body's immune system is completely unique. It teaches your immune system to recognize, respond to, and remember potential invaders. Looking beyond nutrition to information is a profound paradigm shift, and 4Life Transfer Factor is the only product available that leverages this powerful paradigm.

The discovery of transfer factors.
In 1949, Dr. H. Sherwood Lawrence, a New York University immunologist, determined that an immune response could be transferred from a donor to a recipient through a white blood cell extract. He concluded that the extract contained a factor capable of transferring the donor’s immunity information to the recipient and named the substance 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 a new category of immune system support products. 4Life’s commitment to transfer factor research has progressively raised the standard for modern-day immune system supplementation.
Research that has been done on transfer factors.
In the 50 years since Dr. Lawrence’s pioneering work on transfer factors, an estimated $40 million has been spent researching transfer factors and hundreds of scientific papers have been published documenting their effectiveness.
Recent independent studies report that 4Life Transfer Factor and 4Life Transfer Factor Plus Tri-Factor Formulas boost Natural Killer cell activity a remarkable 283% and 437% when your body needs it.
What are transfer factors?
Transfer factors aren’t vitamins, minerals, or herbs—substances that add nutrients to the body. Transfer factors are molecules that actually transfer immune memory and knowledge from one immune system to another.
4Life Transfer Factor supports healthy energy levels by promoting the effectiveness of your immune system. When your immune system is working as it should, you have plenty of energy to do the things you love. Plus, the more energy you have, the faster your body responds to any new problem it encounters.

How 4Life Transfer Factor supports the immune system.
Transfer factors are some of the most unique molecules in your body. They carry important messages to immune cells all over the body, helping them fight harder and more effectively to keep you well. Transfer factors provide intelligence to the immune system in three very important ways:
- Recognize - transfer factors help immune cells identify invading germs and other problems more quickly.
- Respond - transfer factors help speed up the immune system’s response to an invader after it’s been identified.
- Remember - transfer factors lend a hand in remembering the specific makeup of each germ your immune system encounters, so the next time it comes around, your body knows exactly what it is, and what to do.
Why you need 4Life Transfer Factor even if you eat healthy foods.
Healthy foods provide your body with important nutrients to help keep it strong. Immune cells definitely need this nutrition, but they also need education. That’s what 4Life Transfer Factor provides the education and information to help immune cells know what they should be doing to keep the immune system running at peak performance.
Where 4Life Transfer Factor comes from.
Nature has perfected a way to help keep its young healthy. A mother passes on vital immune know-how (gathered from her own experiences) in the first critical days of life. Mammals pass on this information through the mother’s first milk, or colostrum, while other animals pass the information through egg yolk. Transfer factors and nanofraction molecules are important components of this education, acting as nature’s first supplements.
Using patented and patent-pending processes, 4Life extracts transfer factors from cow colostrum and chicken egg yolk to provide a wide range of immune system support. 4Life obtains nanofraction molecules from cow colostrum using a nano filter.
Chickens and cows live outside, leaving them exposed to a variety of germs, which their immune systems must battle in order to stay healthy. Both transfer factors and nanofraction molecules can be safely transferred to humans, making cow colostrum and chicken egg yolk excellent sources for immune system support.
