Host Defense® Mushrooms™ by Fungi Perfecti®, LLC

Nature's Nootropics

We are a family-owned company specializing in functional food mushroom mycelium supplements to support natural immunity and whole body wellness.* With over 40-years of experience, we are one of the best-documented and longest-standing certified organic mushroom companies in the U.S. Every mushroom ingredient in every Host Defense product is grown at our own farm near the Olympic Rainforest in Washington State.

For centuries, mushrooms have been trusted functional foods for supporting health. Host Defense not only preserves this wisdom of nature, but we also expand its impact through cutting-edge modern research and education about the power of mushroom mycelium. Mycelium helps to support the immune system of humans, as well as the health and immunity of the natural habitats where it grows.

Our global mission includes collaborating with doctors to help support immunity and health, educating communities about growing mushrooms for food, investing in integrated mushroom technologies to break down or neutralize toxic wastes, pioneering strategies to save the honey bee using fungi, and protecting the natural environment and all its inhabitants. As we continue to spread the word about the benefits of mushrooms and mushroom mycelium, Host Defense is committed to the integrity of our brand and putting people and planet at the forefront of what we do every day.
