About Transfer Factor - Transfer factors are thought to contain protein and RNA, but no DNA. Their small size-a molecular weight of less than 10,000-helps render them nonallergenic and enables them to retain full potency when taken orally. The colostrum of all mammals is, in fact, rich in transfer factor, and is critical for conferring passive immunity to newborns when ingested during breastfeeding or suckling.

What Is Transfer Factor? - Transfer factor molecules function as a highly effective immune messaging system made up of small protein chains and other related compounds. Transfer factors occur in white blood cells of humans and animals. When foreign organisms are encountered by select immune cells they produce transfer factors specific to the invading organism. These transfer factors are then passed along to other immune cells "passing the message" of a foreign organism and the characteristics of the organism. Current research indicates that these immune compounds are identical from one species to another. Thus making it possible for transfer factors from cows and chickens to be beneficial in human health. Transfer factors are designed by nature to transfer critical immune information. These compounds are most prevalent in colostrum and egg yolks. Through these two sources, all animals are given temporary immunity to all of the organisms to which their mothers have been exposed. This allows the young animal some protection until its immune system is more fully developed. Likewise, this temporary protection can be utilized by humans of any age.

 Transfer factors are molecules that reside in the bodies of all animals. They are messengers, passing immunity information about the presence of an immune threat-whether external or internal-and how to properly respond-from one immune cell to another.
