About Host Defense - Reishi (Ganoderma lucidum) 120 capsules

Host Defense Reishi features Ganoderma lucidum mycelium, a traditional adaptogenic mushroom used to support stress resilience, restful sleep, and healthy immune function. Developed by mycologist Paul Stamets, this formula uses certified organic mycelium grown on whole oats, preserving a broad spectrum of naturally occurring beta-glucans, triterpenes, and other bioactive compounds.

Why It's Worth Considering: Host Defense uses a fresh, freeze-dried mycelium extraction process rather than dried powder alone, which may help retain a wider range of active constituents compared to conventionally processed mushroom supplements.
