Should I take Transfer Factor Classic or Transfer Factor Plus?
If an individual should choose to use Transfer Factor Classic, their immune system may be supported in ways that it otherwise would not. Transfer factors work as instructors to the different members of the immune system. This instruction assists the function of the immune system in recognizing and fighting outside threats to your health. Transfer factors are immune modulators, which means that they are able to support healthy immune function by an Inducer Factor as well as a Suppressor Factor. In addition, an independent study showed that 4Life's Transfer Factor was shown to increase the Natural Killer cell (NK) activity by more than 100%. This is an important discovery in that NK cells carry the immune messaging cytokines, which direct battle with outside threats. When NK cell count is increased the immune system is working more effectively.
Transfer Factor Plus is different from Transfer Factor Classic in that it has additional ingredients. These ingredients include cordyceps, IP-6, maitake mushrooms, beta glucan, zinc, and shiitake mushrooms that help initiate a stronger stimulating immune response than that of Transfer Factor. Transfer Factor Plus strengthens both the innate immune system (the immune information an individual is born with) and the adaptive immune system (the immune information an individual's immune system has obtained throughout life). For your individual condition, either or both of these products may be of benefit to you because of its supporting and strengthening. If you choose to use these products, please consult your physician to make sure there will be no complications or interactions associated with your current state of health.
Can pregnant women take Transfer Factor?
There have been no adverse responses reported while taking Transfer Factor during pregnancy. As with all supplements, consult a physician before use.
Is Transfer Factor Casein and Gluten free?
Gluten is another extracted protein and is predominately isolated from wheat, rye and barley. Because Transfer Factor XF is extracted from colostrum, gluten is not found in Transfer Factor.
Does Transfer Factor Plus contain yeast?
Transfer Factor Plus contains a component derived from baker's yeast called beta glucans. Transfer Factor Plus does not contain whole yeast however.
Can I discontinue taking Transfer Factor or is it necessary to take it continuously?
Ideally Transfer Factor should be used daily to continually work to support the immune system. If you discontinue taking Transfer Factor your immune system will miss out on its daily support.
Is it safe to take multiple capsules of Transfer Factor a day?
There is no known toxicity level associated with Transfer Factor.
Are there research studies available on Transfer Factor?
4Life has made available three booklets containing condensed information from the volumes and volumes of research available on Transfer Factor and the components that were brought together in Transfer Factor Plus. The first booklet is "Transfer Factor" by William Hennen, Ph.D. the second is called "Enhanced Transfer Factor", also by Dr. Hennen. A third booklet by a member of 4Life's Medical Advisory Board, Rita Elkins, MH, is also entitled "Transfer Factor", and is written in layman's terms so the general population can gain additional knowledge. Each of these booklets contains hundreds of additional references.

Why do we need to use Transfer Factor if we received immune information when we were infants?
The transfer factors we received as infants are just purposeful as those available in Transfer Factor. As infants, mother's colostrum gave immune information while our immune systems were not fully developed, but the transfer factors were absorbed into the bloodstream and eventually were used up to become part of the functioning immune system, consisting of lymphocytes, natural killer cells, macrophages, etc. The information provided at birth was to work against the specific threats experienced by your mother at that time; after years of life new threats to the immune system exist. By using oral transfer factor we are providing the same type of immune information we received at birth.
Will Transfer Factor or Transfer Factor Plus help my specific medically diagnosed condition?
Unfortunately, 4Life is unable to prescribe specific supplements for identified conditions; we are only able to describe system function that may be supported through supplementation. Overall, Transfer Factor and Transfer Factor Plus are designed to support normal immune function. Additional information is available in "Transfer Factor" or "Enhanced Transfer Factor" by William Hennen, Ph.D.
I have heard reports of people exceeding the recommended serving size of Transfer Factor. Is this safe?
Transfer Factor has been consumed for many years with no reported side effects. Studies have shown no toxicity. The recommended maintenance amount is 3 capsules a day.
Can a person use more than the recommended serving size of Transfer Factor Plus?
Some individuals do use more for added immune support during short duration. The best and safest way to begin using Transfer Factor Plus is to use the recommended serving size as listed on the product label.
How does Transfer Factor react to heat?
Long-term exposure to high temperatures can degrade potency and possibly neutralize Transfer Factor activity. Transfer Factor should be stored in a cool, dry environment.
Can people who are lactose intolerant use Transfer Factor?
Yes. The large proteins, such as lactose, are filtered out during the extraction process. Are transfer factors made of sugars, proteins or fats? Isolated transfer factors have been determined to be a chain of small peptides consisting of 44 amino acids. Amino acids are the building blocks of proteins.
Is Transfer Factor safe?
Yes. Researchers have given huge doses of transfer factor to volunteers in an attempt to trigger some sort of adverse reaction. No negative side effects were observed, even with massive doses.
