Transfer Factor

How does Transfer Factor work?

Transfer factor might boost immunity to specific diseases.

Are there safety concerns?

Transfer factor that has been derived from humans seems to be safe when used for up to two years. Transfer factor that is derived from cows seems to be safe when used short-term, up to three months. It can cause fever in some people. Transfer factor given by injection (shot) can cause swelling and pain where the injection is given.

There is some concern about the possibility of catching "mad cow disease" (bovine spongiform encephalitis, BSE) or other diseases from products that come from animals. "Mad cow disease" has not been transmitted by transfer factor, but it is probably wise to avoid animal products from countries where mad cow disease has been found.

Do not take transfer factor if:
  • You are pregnant or breast-feeding.

Dosing considerations for Transfer Factor.

The following doses have been studied in scientific research:

  • For preventing shingles (varicella zoster infection) in children with leukemia: a single dose of transfer factor (from humans) that is specific for the varicella virus is given. The health provider giving the shot calculates the proper dose based on the child's weight.
