Transfer factors are tiny molecules that educate the immune system about known and potential threats from foreign invaders and even cancer cells. They were discovered in 1949, but the discovery caused only quiet celebration as the technology needed to produce large quantities for disease treatment did not exist. It does now. More than 50 years after their discovery, the true utility of transfer factors in disease treatment and prevention can finally be researched and realized. Several issues are yet to be resolved — including optimal dosing strategies and how immune system activation via transfer factors affects autoimmune conditions. Who knows what the story on transfer factors will read like in ten years. However, perhaps more than any other emerging modality in the treatment and prevention of disease, transfer factors hold incredible promise.
