Transfer Factor is a term for low-molecular-weight molecules derived from colostrum or leukocyte extracts, thought to transfer cell-mediated immunity. Its use to support the lymphatic system is based on its immunomodulatory effects, as the lymphatic system is central to immune function. Scientific studies, mostly in vitro or in animal models, have shown that Transfer Factors can enhance certain immune responses, such as increasing natural killer (NK) cell activity and modulating cytokine production. However, high-quality human clinical trials are limited, and many published studies are small, lack rigorous controls, or are conducted by groups with commercial interests.

Historically, Transfer Factors were first described in the 1950s and explored as a way to confer immunity to specific pathogens. While there is some evidence that oral or injected Transfer Factor preparations may enhance immune responses, especially in immunocompromised patients, the direct impact on the lymphatic system as a whole is less well studied. Most claims focus on general immune enhancement, not specific lymphatic support.

Overall, while there is a scientific rationale for Transfer Factor influencing the immune system—which includes the lymphatics—the direct evidence specifically supporting its use for lymphatic health is limited. The strength of the evidence is modest, with more robust studies needed to confirm its efficacy and mechanism of action in this context.
