Nature holds many secrets, and scientists have been working for years and years to discover them. Some scientific discoveries are exciting only to a small group of devoted scientists, but some discoveries change the world.

Some discoveries lead to better technology, or they can even benefit the wellbeing of humanity. Transfer factors are a discovery that has changed the world.

Discovery of Transfer Factors

In 1949, Dr. H. Sherwood Lawrence, a New York University immunologist, determined that an immune system response could be transferred through a white blood cell extract from a donor to a recipient. Dr. Lawrence subsequently coined the term “transfer factor.”

In 1997, David Lisonbee, the founder of 4Life Research, discovered a patent for extracting transfer factors from cow colostrum, and he immediately wanted to know more. Later, David licensed the patent and 4Life brought the first transfer factor supplement, 4Life Transfer Factor Classic, to market.

There is one more valuable source of transfer factors we use at 4Life: chicken egg yolk. 4Life also has a patent for the process of extracting transfer factors from chicken egg yolk (U.S. Patent6,468,534).

Cow colostrum and chicken egg yolk are two widely available sources of transfer factors that allow for the mass production of transfer factor supplements.

The discovery of transfer factors and their presence in these two sources was a major scientific advancement and has provided an important means of promoting wellbeing worldwide.

What Do Transfer Factors Do in Your Body?

Transfer factors are quite different from vitamins, minerals, and herbs.

Vitamins and minerals are essential nutrients your body uses to carry out many important functions, such as the conversion of food into energy (metabolism).

Herbs contain phytonutrients, natural compounds found in plant foods that act in a variety of ways to support optimal body function.

The human immune system is diverse and complex and has over 200 subtypes of cells, proteins, and mediators. Ideally, all components will work in a balanced way and perform their tasks. In reality, though, immune system balance can be disrupted by stress, poor diet choices, and even pollution.

What are 4Life Transfer Factors?

4Life Transfer Factors are a range of food supplements exclusively developed by 4Life Research. These supplements are formulated with vitamins, minerals, plant extracts and a patented extraction of transfer factors, with a specific focus: to support and help maintain the normal functioning of the immune system.

4Life Transfer Factor Product Benefits

To illustrate the benefits of 4Life Transfer Factor supplements, let’s focus on one type of immune system cell, Natural Killer cells (NK cells).

These cells need to stay highly active to function well. With proper activation, NK cells identify and destroy invaders quickly and effectively.

You can get your daily dose of vitamins and minerals for a normal functioning of the immune system from many 4Life Transfer Factor products.* To learn more about them, click the links below:

Natural Sources of Transfer Factors:

4Life Transfer Factors supplements utilize transfer factors extracted from two main sources: cow colostrum and egg yolks. Colostrum is the first milk produced by mammals, including humans, shortly after giving birth.
