Host Defense supplements at Welzo offer expertly formulated mushroom-based solutions designed to support immune resilience, cognitive function, energy, and overall vitality. Host Defense was founded in 1980 by Paul Stamets as part of Fungi Perfecti. Fungi Perfecti, the parent company, was established with the goal of bridging the gap between people and fungi. Host Defense is globally recognised for its scientific integrity and commitment to using sustainably grown, organic mushrooms. Each product in this collection is crafted to deliver the natural therapeutic potential of functional fungi, helping users take a proactive, research-backed approach to long-term health.

For those seeking clinical-grade mushroom extracts, Host Defense shares similar values with MRL (Mycology Research Labs), known for its research-driven supplements used in integrative healthcare. Together, these collections offer users a comprehensive toolkit for natural immune and systemic support.
