Transfer Factor – New Research, New Hope
The use of transfer factor represents one of the most exciting advances in immune system health.
is based on the theory that key immune information can be transferred from cell to cell.
These cells then teach
our immune system to recognize specific viruses or bacteria. This is particularly exciting given the therapeutic
role transfer factors may play in activating and enhancing immunity to individuals suffering from chronic illness.
The transfer factor theory has been the subject of intense research for more than fifty years, producing a wide
body of knowledge about transfer factor’s contribution to immune health.
Transfer Factor – Immunity through Memory
The immune system’s job is to recognize potentially harmful invaders, called pathogens, and then to destroy or neutralize
them. If our bodies are able to immediately recognize a pathogen, the individual is able to effectively defend against
viral, bacterial, fungal, and other diseases. Transfer factor molecules are the key to the immune system’s memory
of past pathogen exposure, and thus, are an integral component for maintaining immune system integrity and effectiveness.
Transfer factors are tiny protein molecules, which are produced by immune cells called T cells. Transfer factors
allow the immune system to remember conditions for which immunity has already been established.
When a person has been infected, for example, with chickenpox in childhood, the body develops a memory of that illness
which prevents the person from becoming re-infected later in life. In the future, the specific immune transfer factor
molecule for chickenpox will endow the immune system with the exact “blueprint” of what chickenpox looks
like, and the body will be able to quickly recognize and respond to any possible re-infection before it can cause
Transfer Factor Targets Specific Viruses, Bacteria, Yeasts and Fungus
There are several million naturally occurring transfer factors circulating in the human body. However, a healthy
body can still function even though it may be missing about 50,000 different transfer factors.
Many of these “immune memory molecules” were introduced to us from our mother’s colostrum. This “first
milk” as it is called, is the richest source of concentrated transfer factors known to scientists. Transfer
factor in colostrum has the sole purpose of transferring immunity from the mother to the baby’s immature immune system.
This imparts the mother’s immunity to the baby to help ensure survival while the baby’s immune system matures.
For individuals challenged by specific pathogens, whether known or unknown, supplementation with the appropriate
transfer factor molecule may provide the “missing link”, thereby allowing the immune system to target and
destroy the offending pathogen and mitigate the symptoms of the disease. Chronic fatigue syndrome, fibromyalgia,
chronic candidiasis, Burkitt’s Lymphoma, post-lyme syndrome, HIV infection, and multiple sclerosis are produced by
What is the source of Transfer Factor?
All mammals produce transfer factor, however scientists prefer to work with bovine (cow) colostrum. A healthy cow
already produces millions of different transfer factors, but when the cow does come into contact with a pathogen
such as a virus, it produces a new transfer factor for that specific virus or pathogen.
Transfer factor is able to pass through the stomach unharmed by digestive enzymes and stomach acids. The calf is
then able to easily absorb this immune memory molecule, which gives it immunity to all the same pathogens as the
calf’s mother. This inherited immunity will protect the baby from the same disease-causing organisms the mother was
Transfer factor crosses mammalian species lines. When a person absorbs transfer factor from a cow’s colostrum the
person develops resistance to the pathogen to which the cow was exposed.
How is Transfer Factor Produced for Human Consumption?
Due to practical considerations in the manufacturing and processing of transfer factor, bovine colostrum is the
preferred source of transfer factor. It is the easiest colostrum to procure in quantity and it produces significant
amounts of various transfer factors.
Colostrum from healthy, organically-fed cows is filtered and purified to provide a mixture of pure transfer factor
molecules. Numerous rigorous techniques including further purification and isolation result in pure transfer factor.
Every lot produced undergoes rigorous testing, to ensure that the appropriate and effective levels of each transfer
factor are present, before it is encapsulated and bottled.
Also, people who are lactose intolerant or who have allergies need not be concerned about a reaction since all traces
of milk proteins and lactose are removed during the extraction and concentration process.
How To Use Transfer Factor
How will a person know if transfer factor will be beneficial for him/her? It is important to be tested for a variety
of different pathogens, to determine potential causative factors. If the test comes back positive, the patient should
discuss the use of transfer factors with his/her physician. Certain conditions, for example, Chronic Fatigue Syndrome,
may be triggered by a variety of pathogens.
Research has indicated that several viruses may be playing a causative role. These include several members of the
herpes virus family, all known to establish life-long residence in the infected individual. Many published clinical
and research studies have indicated that there may be some relationships or involvement in CFS with the following
pathogens: Herpes Virus Six (variants 6A and 6B), Epstein Barr Virus (EBV), and Cytomegalovirus (CMV).
Transfer factor will not remove or “cure” the problem in itself; rather transfer factor works to assist
and support normal immune system functioning. At the onset individuals typically begin with a high dose and then
eventually taper down to a minimum maintenance dose.
The main drawback of transfer factor is its cost. The highly complex technology which ensures that the cow contains
the appropriate cross-species transfer factor molecules (as discussed above), as well as manufacturing, purifying,
and testing each lot for the desired transfer factor activity, combine to make this very specialized product an expensive
Furthermore, several months of product usage are frequently required before the individual begins to experience
an enhanced immune system, which may increase the expense and require a “wait and see” approach.
There may also be an initial reaction to transfer factor, as the immune system begins to recognize and respond to
pathogens that it was formerly unable to recognize. This will cause immune system activation that can result in an
increase in body temperature and flu-like symptoms. Clinicians experienced in transfer factor therapy recognize this
as a normal reaction that is characteristic of other products that can impact the immune system, such as whey protein.
Over Fifty Years of Research into Transfer Factor
Over fifty years of research, producing more than 3,000 articles in peer-reviewed scientific journals, confirms
transfer factor’s ability to support the body’s immune system response mechanism.
Transfer factor’s significance as immune system support is underscored by the fact that an independent committee
of researchers, scientists and doctors, formed a professional organization dedicated to the study of transfer factor.
The International Transfer Factor Society (ITFS), is comprised of world-renowned medical experts such as Giancarlo
Pizza, M.D. of Italy, Dimitri Viza, M.D. of France, and Paul H. Levine, M.D. of the United States.
