Transfer Factor – a biologically derived compound
Transfer Factors are naturally occurring substance found in blood and also sources like colostrum and egg yolk. While 4Life uses the term in its product names, it is not a marketing creation. In scientific literature, this compound is also known by names such as Dialyzable Leukocyte Extract, Bovine Transfer Factor, Facteur de Transfert, Factor de Transferencia, and more.
It is a biologically active component derived from immune-rich sources such as colostrum and egg yolk, which have been studied for their biological properties
Scientific background and research
Transfer Factors were first described in the 1950s and have since been the subject of numerous scientific studies. They have become a topic of interest in the field of immunobiology.
They are cited in scientific literature under a variety of names and acronyms, including TF, DLE, BTF, HDF, and others, depending on the source and method of extraction.
Do Transfer Factors support the immune system?
In accordance with EU regulations, food supplements cannot be marketed with claims to prevent or treat disease. However, it is worth noting that Transfer Factors are derived from biologically rich materials and have been the subject of scientific research in the context of immune-related studies, although no specific health claims are authorized in the EU.
For example, the review article Transfer Factor: an Overlooked Potential for Immune Support discusses their biological properties and the relevance of continued research into their activity in the human body.
