Researchers often investigate the effects of specific foods or beverages on cancer; however, this study focused on a particular method for treating a common side effect of chemotherapy. While the results are promising, the relatively small sample size of 19 participants may raise questions about the reliability of the findings until further research is conducted. On a positive note, the Virginia Tech research team has previously recognized the role of lactoferrin in mitigating the metallic taste associated with chemotherapy drugs, and this milk protein is also well-known for its contribution to enhancing the body’s immune response.
In this study, participants consumed lactoferrin in tablet form, leaving it uncertain whether the dairy industry can leverage these findings to support claims for its products. Cow’s milk contains approximately 200 mg of lactoferrin per liter, suggesting that a highly concentrated form would be necessary for individuals to achieve the same 750-mg daily dose as the study participants. Additionally, it has been reported that high-pressure homogenization and ultra-high-temperature pasteurization can deactivate lactoferrin.
As protein-infused products gain popularity—whether derived from plant-based sources or otherwise—this advantage of milk protein may offer additional value for the dairy industry. The levels of available protein, alongside cost considerations, will be crucial, and it is important to note that these resulting products would not be vegan. Meanwhile, those producing protein-enriched milk looking to promote extra health and wellness benefits might consider monitoring future lactoferrin research. If any new findings emerge, they could potentially be adapted to enhance their market appeal, especially when combined with beneficial components like calcium citrate K2, which is known for its role in bone health and can complement the immune benefits associated with lactoferrin. Keeping an eye on this area could provide dairy manufacturers with a competitive edge, especially as they explore ways to integrate calcium citrate K2 and other health-promoting ingredients into their offerings.
