Commonly Asked Questions about 4Life Transfer Factor® Innovation

What are transfer factors?

Unlike many supplements you find in health food stores, transfer factors aren’t vitamins, minerals, or herbs (substances that add nutrients to your body). Transfer factors are molecules that transfer immune system memory and knowledge from one entity to another. Transfer Factor science is part of ground-breaking innovation for immune system support.



When were transfer factors discovered?

TF03_Img 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.*



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 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.*

What studies support 4Life Transfer Factor?

4Life Transfer Factors are backed by many scientific studies. In fact, our most recent independent laboratory studies show that core 4Life Transfer Factor products bolster Natural Killer (NK) cell activity in the presence of a health threat, while activating a variety of other immune system cells, such as: B cells, T cells, and macrophages.*†

If I eat healthful foods, why do I need 4Life Transfer Factor?

Healthful foods provide your body with important nutrients that provide strength. Immune system cells need this nutrition, but they also need education. 4Life Transfer Factor educates your immune system cells so your immune system can keep running at peak performance.*

Where does 4Life Transfer Factor come from?

Nature has perfected a way to pass immune information from mother to baby. A mother passes on vital immune system knowledge (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.

Chickens and cows live outside, exposing them to a variety of germs, which their immune systems must battle in order to stay healthy. Transfer factors and nanofraction molecules can be safely transferred to humans, making cow colostrum and chicken egg yolk excellent sources for immune system support.*

What if I don't want to take capsules?

Don't like swallowing capsules? No problem! You can get 4Life Transfer Factor® Classic in chewable citrus-cream tablets or a powder you can add to any food or drink. You can also get 4Life Transfer Factor® Tri-Factor® Formula in chewable citrus-cream tablets. These three products are safe for ages 4 and up!

What is NanoFactor®?

NanoFactor is 4Life’s exclusive extract of nano-filtered cow colostrum.

What is Tri-Factor® Formula?

4Life Transfer Factor Tri-Factor Formula helps balance and support the immune system. It contains ingredients made by the immune system, for the immune system: UltraFactor® from cow colostrum, NanoFactor from cow colostrum, and OvoFactor® from chicken egg yolk.*

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.
