What are transfer factors?

Transfer factors are at the core of the nutritional products 4Life carries. Let's take a look at what exactly they are.

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 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 over 3,000 published studies documenting the ways in which they impact the immune system.

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:

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

  2. Respond. Transfer factors help speed up the immune system’s response to a potential threat after it’s been identified.
  3. 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.
