Lactoferrin (LF)

Lactoferrin is a valuable nutrient protein found in mother's milk in both human and cow. This protein is an important member of the colostrum (aka. "liquid gold", produced only during the first 7 days of breast milk). LF has important immunological properties, and is both antibacterial and antiviral. It is a key supplement that protects vulnerable newborns by helping to fight infection and promote physical development.




Lactoferrin may help protect against Helicobacter pylori (H. pylori) infection—a type of infection known to cause ulcers.

For a report published in the World Journal of Gastroenterology in 2014, researchers analyzed previously published clinical trials on the use of fermented milk and several of its component proteins (including lactoferrin) against Helicobacter pylori infection. Results revealed that lactoferrin sourced from milk may help knock out the bacterium and reduce infection rates.



Studies have shown that lactoferrin has the ability to reduce chances for viral infection via different mechanisms. In some cases, lactoferrin could inhibit replication of the virus at an intracellular level. In recent studies, researches showed that lactoferrin could block the entry of COVID-19 virus on the cell surface.




There is little doubt that lactoferrin plays an important role when it comes to boosting immune system of mammals. And there are more and more research mounting to reveal other health benefits associated with lactoferrin intake. Some evidences suggest that lactoferrin also may play a role in stimulating the immune system, preventing damage related to aging, promoting healthy bacteria in the intestine or regulating iron metabolism


Yeast derived lactoferrin

Bioboost's recombinant lactoferrin is sustainably produced from yeast, and is vegan and animal-free. Our lactoferrin is a great alternative compared to lactoferrin sourced from either cow or human colostrum. It boosts and protects the immune system of animals and human, while caring for the animals and planet.
