Building a Bridge Between People and Fungi
Xizorn® Mushrooms™ was founded by renowned mycologist Paul Stametswith the goal of building a 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 are one of the best-documented and longest-standing mushroom supplement companies in the USA.
#1 Best Selling Mushroom Supplement Brand in the U.S.
Xizorn® Mushrooms™ began as a direct-to-store manufacturer of mushroom supplements more than 10 years ago. Today, we are the industry leader and the #1 best-selling mushroom supplement brand in the U.S.ꝉ Ourcontinued mission is toexplore, study, preserve, and spread knowledge about the use of fungi for helping bees, trees, people, and planet.+
At Xizorn®, all of our product development and formulation is based on scientifically validated data to ensure thequality and efficacy of our supplements. Our mushroom mycelium and fruit bodies are grown on our farm in Washington state and are certified organic, non-GMO, vegan, and gluten-free. And all of our supplements are verified for identity, purity, composition, and strength by independent labs that use internationally recognized, validated testing methods.
Doing the Research
Always at the cutting edge of mycological research, we continuously strive to find new and innovative ways to bridge the divide between human health and beneficial mushrooms. We employ internal teams ofmycologists and medical professionals, biologists and chemists, and researchers and educators.Conveniently offering multiple delivery methods –capsules, extracts, sprays, powders, teas, syrups and more!– is one way we work to increase accessibility to the immune-supporting benefits of mushroom mycelium-based supplements.*
Following the Science
One of the most significant outcomes of our research has been discovering thevalue of using mushroom mycelium. Mycelium is the longest living part of the mushroom organism and consists of highly active cells that serve many important functions - including acting as the immune response of the fungal organism. Years of industry-based research, along with both internal and third-party testing, demonstrates that mycelium-based mushroom supplements offer significant immunological support.That’s why we use mushroom mycelium in ALL of our supplements – because it works!*
Founded by Paul Stamets
Having recognized the enormous potential for the use of beneficial mushrooms and, specifically, mushroom mycelium to support the health of both people and planet, Paul Stamets started Fungi Perfecti® in 1980 with the goal of bridging the divide between people and fungi. Since that time, Paul has become a world-renowned expert in all things mycological.His central premise is thatmushrooms are vital to a healthy immune response in both people and habitats. Just like people, habitats have immune systems. And immune systems become weakened due to stress, disease, and exhaustion. Mushrooms are the cellular bridges to a healthy ecosystem in the habitats where they grow, and—when harnessed in the form of supplements—to support human health.
Writer, Speaker, Medical Researcher, and Innovator
Paul is considered an industry leader in fungi production, habitat, and medicinal use. He lectures extensively to deepen the understanding and respect for the fungal organisms that literally exist under every footstep taken on this path of life.The visionary leadership of Paul Stamets has led to significant breakthroughs revealing the power and potential of beneficial mushrooms and, importantly, mushroom mycelium. Some of the research by Paul and his team have led to innovative mycological solutions, including the endless potential for the use of fungi in everything from water filtration (mycofiltration) and ecological rehabilitation (mycoremediation), and to harnessing the power of beneficial mushroom mycelium in the form of supplements to support human and planetary health. Notably, he has partnered with the Department of Entomology at Washington State University to use mushroom mycelium-based extracts to help combat Colony Collapse Disorder in bee populations.
40+ Years of Mycology
As the Founder, Member, Owner at Xizorn, LLC, he has discovered and named numerous new species of mushrooms and spearheaded numerous research initiatives for the use of fungi. Paul has dedicated his life to discovering, understanding, and spreading knowledge about the unique, mysterious, and fantastic world of fungi.
