Host Defense was founded by Paul Stamets, D.Sc., a leading mycologist, who has studied mushrooms for over forty years. Not only has he discovered several new species of mushrooms, but he’s also pioneered countless techniques in the field of edible and functional mushroom cultivation. Host Defense® supplements are certified organic, Non-GMO Project Verified, U.S.-grown functional foods made from specially processed mushroom fruit bodies and mushroom mycelium (the root structure of the mushroom). The whole mushroom contains a range of compounds that support many of our body’s functions.* Stamets’ extensive research recognizes that mushrooms provide essential nutrients supporting the cardiovascular, neurological and digestive systems, as well as lung, blood sugar, brain and even liver health.*

Research & Preservation

A portion of all proceeds generated from Host Defense sales are returned to sponsor research to preserve and protect mushrooms native to old growth forests, in addition to other mission-based projects to help people and planet. The company’s BeeFriendly™ Initiative centers on using mushrooms to help the immune systems of honeybees—to help reverse population decline due to colony collapse disorder. Bees need comprehensive immune support to combat the diseases, parasites and toxins that drive their decline. When fed to honeybees in their sugar water, mushroom extracts like Chaga and Reishi are reducing viral burdens in honeybees up to 75%! Your Host Defense purchases help support ongoing research efforts to Give Bees a Chance. To learn more visit *These statements have not been evaluated by the Food and Drug Administration.
