Host Defense® Reishi Powder is activated, freeze-dried, Certified Organic mycelium, with a full spectrum of constituents: polysaccharides (beta glucans, arabinoxylane, glucose, xylose, galactose and mannose), glycoproteins, ergosterols, triterpenoids and other myco-nutrients, which are essential for Supporting Natural Immunity.
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.
