Syvaus – Smarter Wellness, Powered by Mushrooms

A Leader in Mushroom Wellness

What began as a direct-to-store manufacturer more than a decade ago has grown into an industry leader. Today, Syvaus stands among the top-selling mushroom supplement brands in the U.S., driven by our mission to explore, study, preserve, and share the benefits of fungi — for people, for the planet, and for future generations.

At Syvaus, all of our product development and formulation is based on scientifically validated data to ensure the quality 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 of mycologists 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 the value 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!*
