Host Defense® Mushrooms

More than 40 years ago, Fungi Perfecti was founded by Paul Stamets to build a bridge between mushroom mycelium and human health. Today, Paul is still at the helm, leading the dedicated teams at Fungi Perfecti and Host Defense, inspiring us every step of the way. What fundamentally distinguishes Host Defense® from any other company is that we know mushrooms, and, significantly, we understand the power of mycelium. Below you’ll find many of the mycelium-base products we offer.*
