FREQUENTLY ASKED Questions

Unlike common supplements you find in every health food store, transfer factors aren’t vitamins, minerals, or herbs (substances that add nutrients to your body). Instead, they’re molecules that transfer immune memory and knowledge from one entity to another, and are part of a ground-breaking approach to immune system support.

A newborn baby comes into the world with an inexperienced immune system. The mother’s first milk is rich in colostrum and transfer factors. Transfer factors are molecules that “transfer” important immune knowledge from mother to baby. This immune education helps the baby’s natural defense system work better.

                      The first lesson a mother gives her newborn is a course in self-defense.

In the decades since Dr. Lawrence’s pioneering work on transfer factors, researchers and institutions have spent an estimated $40 million studying transfer factors and have published hundreds of scientific papers documenting the ways in which they impact the immune system.

An independent study reported that 4Life Transfer Factor® Tri-Factor® Formula and 4Life® Transfer Factor Plus® Tri-Factor® Formula boost natural killer cell activity by up to 283% and 437% respectively.*

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 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.

Transfer factors are some of the most unique molecules in your body. They carry important messages to immune cells. Transfer factors help the immune system to:

Recognize. Transfer factors help immune cells quickly identify invading threats.

Respond. Transfer factors help speed up the immune system’s response to a potential threat after it’s been identified.

Remember. Transfer factors lend a hand in remembering the specific makeup of the threats your immune system encounters, so the next time it’s encountered, your body knows exactly what it is and how to combat it.

Today, almost all immune system products on the market (vitamins, minerals, and herbs) have one thing in common: they provide temporary nutrition. However, the best long-term solution for an active, balanced immune system response is information. 4Life Transfer Factor works with your body's 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.

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 new threats.

Healthy foods provide your body with important nutrients that provide strength. Immune cells need this nutrition, but they also need education. 4Life Transfer Factor provides information to help immune cells know how to keep your immune system running at peak performance.

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.

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 nano-fraction molecules can be safely transferred to humans, making cow colostrum and chicken egg yolk excellent sources for immune system support.

It was first noticed that when newborn cows didn't or couldn't nurse, they often quickly died. Infection, and not starvation, was usually the cause. Researchers realized that the mother was passing immunity information to the calf after birth and that the only means could be transfer factors in her milk. It was then realized that birds must have a similar mechanism for passing immunity on to their own young.

Both chickens and cows live mainly outside, where they eat off the ground, drink from shared water sources, endure varying weather conditions and contend with the challenges of communal living. This leaves them exposed to a variety of germs, bacteria and viruses, which their immune systems must battle and then remember in order for them to stay healthy. It's the heroic nature of their immune systems, needed for survival that makes them ideal donors for transfer factors. Because transfer factors can be shared safely and effectively from human to human, chicken to human or cow to human, either source alone offers excellent immune support. Combined, they offer the broadest range of immune support available.

4Life uses both the cow and chicken to obtain transfer factors that provide a wide range of immune support. For targeted support, 4Life uses egg sources specially farmed to benefit specific body systems. 4Life licenses the cow colostrum patent. And 4Life pioneered extracting transfer factors from chicken eggs and holds the patent and has patents pending on this source. 4Life has streamlined the extraction processes, which concentrate the power of transfer factors in unique and innovative supplements that help strengthen the immune system.

Transfer Factor E-XF™-4Life Transfer Factor Plus® Advanced Formula and other 4Life Transfer Factor Advanced Formula products are made from 4Life's proprietary scientifically proven Transfer Factor E-XF blend. Developed exclusively by 4Life using patented and patent-pending technology, the blend combines the immune knowledge of two sources to deliver the benefits of transfer factors from both cow colostrum and chicken eggs to offer the broadest range of immune knowledge possible.

4Life Targeted Transfer Factor®- 4Life's line of Targeted Transfer Factor products is part of a revolutionary support system. Scientifically researched and developed by 4Life, they target the power of transfer factors extracted from eggs specially farmed to benefit specific body systems.

Unlike dried egg yolk or cow colostrum, 4Life's Transfer Factor E-XF contains concentrated transfer factors. Through patented processes, 4Life separates transfer factors from the other components in egg yolks and cow colostrum to capture a broader range of immune-enhancing transfer factors. Dried eggs or cow colostrum alone may contain only small amounts of actual transfer factors along with other compounds. In addition, Transfer Factor E-XF goes through a special stabilization process to protect their effectiveness.

Transfer factors are a natural molecule and have been safely used in supplement form for many years. Throughout the history of transfer factors use, there have been no reports of serious adverse reactions, even when clinically administered in excess or with normal doses given over many years.

Yes. 4Life complies with all the regulations set by the Philippine FDA. The “NO APPROVED THERAPEUTIC CLAIMS” label seen on most Transfer Factor products is also required, similar to all food supplement products registered with FDA.

In the 50 years since Dr. Lawrence's pioneering work on transfer factors, an estimated $40 million has been spent on scientific research and hundreds of scientific papers written that document its effectiveness. Several independent books have also been authored. Independent studies have also shown the ability of 4Life Transfer Factor products to increase immune system effectiveness.

Yes. Studies conducted by the Russian Academy of Medical Science show that 4Life Transfer Factor Advanced Formula boosts immune activity by 283 percent* and 4Life Transfer Factor Plus Advanced Formula boosts it 437 percent*! The study compared 4Life Transfer Factor products to individual herbs and ingredients known to improve immune response such as noni, dry cow colostrum, echinacea and others. An earlier study showed that 4Life Transfer Factor Classic boosted NK cell activity 103 percent.

Everyone who needs an extra immune boost, needs to suppress an overactive immune system or who simply wants to maintain their everyday health benefits from taking 4Life Transfer Factor products.

Only people who have undergone organ transplant and are taking immuno suppresants are not encouraged to take Transfer Factor. Immune suppressants are medicines intended to weaken the immune system so it will not reject the "foreign" organ.

Unlike the antibodies and proteins found in egg yolks and colostrum alone, transfer factors readily survive the digestion process and are easily absorbed. Stomach acids and digestive enzymes won't degrade their potency.

Yes. Transfer factors themselves are non-allergenic. 4Life's extraction process avoids or removes common allergens in egg and colostrum sources. Any remaining lactose in colostrum-derived transfer factors is far below the amounts that typically cause reactions. (As precaution, people with allergies specifically to egg yolks, should check with their physician before taking 4Life Products with Transfer Factor E-XF or Targeted Transfer Factor.)

4Life Transfer Factor products that contain only transfer factors are safe for infants and children up to 18 years of age. Transfer factors were, in fact, designed by nature for newborns. 4Life offers 4Life Transfer Factor Kids® just for children, which combines the power of Transfer Factor XF with 22 essential vitamins and minerals in tasty, chewable tablets that provide the immune and nutritional support that growing kids need.

The transfer factors you received as an infant helped educate and strengthen your naive immune system. But, immune cells regularly die and are replaced, so the ongoing protection from transfer factors lasts only a short time. Because today, more than ever, we're exposed to new immune challenges, regularly taking transfer factors to strengthen your immune system is critical to your health.

Our bodies create new immune cells almost every day, which need instruction. To meet this need, 4Life Transfer Factor products should be used daily to give the immune system the continual support it needs to recognize and respond to new and emerging health threats. 4Life Transfer Factor Plus Advanced Formula, 4Life Transfer Factor Advanced Formula and 4Life Transfer Factor Classic can safely be combined with Targeted Transfer Factor products to optimize overall immunity as well to target specific systems.

4Life offers both a chewable version of 4Life Transfer Factor as well as chewable 4Life TF Kids™. 4Life also offers 4Life Transfer Factor Immune Spray, a great-tasting throat spray that combines the antibacterial properties of colloidal silver with the power of Transfer Factor XF. 4Life Transfer Factor capsules are also easily opened and the contents mixed with formula, pureed foods or drinks.
