Host Defense and founder Paul Stamets — mycologist and author of six books on mushroom cultivation and identification, including the definitive text Growing Gourmet & Medicinal Mushrooms—are proud to offer the finest mushroom supplements available today. 

Host Defense is built on Paul Stamets' visionary research into the power and potential of mushrooms, especially mushroom mycelium, the root-like structures found growing below ground. The power of Host Defense comes from the discovery that the mycelium is the immune system of the mushroom.

Just as mycelium helps to support the immune system of humans, it also supports the health and immunity of the natural habitats where it grows. Mushroom mycelium is a cellular bridge connecting bees, trees, bears, plants and humans to the ecosystems in which they live. Our work is to build a healthier world with the power of mushrooms.
