- Who discovered transfer factors and when?
H. Sherwood Lawrence discovered a revolutionary substance. He determined that an improved immune response could be transferred from an individual who has recovered from a specific illness to a recipient who has not experienced that illness. He referred to this substance as transfer factors. It was in 1949, Dr. H. Sherwood Lawrence made the revolutionary discovery while studying tuberculosis. He determined that an immune response could be transferred from a donor to a recipient by injecting an extract of white blood cells (leukocytes) from a previously infected, now healthy, subject into a newly infected patient. He found that this extract contained a factor capable of transferring immunity. He named the substance "transfer factor." Dr. Lawrence's discovery came in the midst of the discovery and use of antibiotics. Transfer factors have been used throughout the antibiotic age in different regions of the world such as China, Poland, Italy and others, but never have been available commercially due to the lack of technology. In the fifty years since Lawrence's pioneering work, an estimated $40,000,000 has been spent on research resulting in over 3,000 published scientific papers documenting the benefits of transfer factors. The world's leading scientists and physicians have established the safety and remarkable immune system benefits of transfer factors. The processing methods that allow for large scale extraction of transfer factors have only recently been perfected and a commercial product has only been available within the last few years.
- How does ingesting transfer factors orally compare to injecting transfer factors from blood preparations?
Generally, the effects are very similar no matter how transfer factors enter the body. Because transfer factors originate in the blood, the source of transfer factors is identical whether they reenter the body in concentrated form such as 4Life® Transfer Factor™, or by injection. Injectable transfer factors are often prepared from blood, while orally ingested transfer factor products are generally prepared from colostrum and egg yolk. Both are well absorbed by the body, but orally ingested transfer factor products can be consumed on a daily basis without discomfort or safety issues associated with injections.
