Find the answers to your most commonly asked questions below.

Q: What are transfer factors?

A: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.

Q: When were transfer factors discovered?

A: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. Q: What research has been done on transfer factors?

A: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.

Q: How does 4Life Transfer Factor support my immune system?

A: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.

Q: Why does my immune system need support?

A:When your immune system works hard, you’re able to work and play hard. But when immune system function is impaired by too little sleep, environmental hazards, poor diet, or a high-stress lifestyle, it can’t do its job. You should care about your immune system, because it cares for you.

Q: How can 4Life Transfer Factor support healthy energy levels?

A: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.

Q: If I eat healthy foods, why do I need 4Life Transfer Factor?

A: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.

Q: What is Transferceutical™Science?

A:Transferceutical Science encompasses the research and development of products that educate the immune system to recognize, respond to, and remember potential threats. Transferceutical Science and products were pioneered by 4Life Research.

Q: How is 4Life Transfer Factor different from other products?

A: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.

Q: Where does 4Life Transfer Factor come from?

A: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.

Q: What is NanoFactor™?

A:NanoFactor is 4Life’s exclusive extract of nanofraction molecules from cow colostrum. NanoFactor provides essential intuition to the immune system, so immune cells know when to act, how to act, and when to rest.

Q: What is Tri-Factor®Formula?

A:4Life Transfer Factor Tri-Factor Formula brings together the intelligence of 4Life Transfer Factor and the intuition of NanoFactor, to regulate, boost, and balance the immune system…according to what your body needs.

Q: Does 4Life have patents for their transfer factor products?

A:Yes. 4Life has obtained U.S. patents for its transfer factor products from cow colostrum and chicken egg yolk. The extraction process for transfer factors from chicken egg yolks is protected by U.S. patent 6,468,534;exclusive combination techniques for transfer factors from cow colostrum and chicken egg yolks are protected by U.S. patent 6,866,868.

Q: What is RioVida®?

A:4Life Transfer Factor RioVida Tri-Factor Formula is the only transfer factor drink in the world. It combines Tri-Factor Formula with powerful antioxidant fruit juices, including açaí, blueberries, pomegranates, elderberries, and purple grapes. The fruits found in RioVida support healthy cardiovascular, digestive, urinary, and immune system functions.

Q: What is Targeted Transfer Factor®?

A:Using a patented process (US Patent 6,468,534), 4Life extracts transfer factors from chicken egg yolk. These transfer factors are then focused to benefit specific body systems. 4Life’s Targeted Transfer Factor line includes products for the cardiovascular system, endocrine/metabolic systems, male prostate health, female reproductive system and breast health, and brain.
