Modern science continues to recognize the array of health-supporting compounds found in mushrooms. Host Defense is a strong proponent of the peer-reviewed process and scientific studies. This rigorous vetting process is the best way we have today to separate scientific research on mushroom efficacy from opinion or marketing tactics.

Host Defense has a dedicated research team of over ten mycologists that studies mushrooms. For 35 years we have been researching, writing on, teaching about, cultivating, and producing mushrooms. Our staff is active within the mycological communities, attending, teaching, and sharing our knowledge of mushrooms at educational and scientific congresses throughout the world.
