Host Defense® Mushrooms™ was founded by renowned mycologist Paul Stamets with the goal of building the bridge between people and fungi. We specialize in mushroom mycelium-based supplements to support natural immunity and whole body wellness.* Based near the Olympic Rainforest in Washington state, we’re one of the best-documented and longest-standing mushroom supplement companies in the USA.
Conveniently offering multiple delivery methods – including capsules, extracts, sprays, and powders - as well as other products like MycoBrew drink mixes, we work to increase accessibility to mushroom mycelium-based products. Our mushroom mycelium and fruit bodies are certified organic, non-GMO, vegan, and gluten-free. We base all product development and formulation on scientifically proven data to ensure the quality of our supplements.*
