Host Defense
Privately Held
Paul Stamets, Founder 1980

Mushrooms have surged in popularity in recent years, but long before they became a wellness trend, Paul Stamets was dedicating his life to understanding them. Widely regarded as the godfather of modern mycology, Stamets has spent more than forty years researching, discovering, and championing the power of beneficial mushrooms, and Host Defense is the culmination of that life's work. After vetting countless mushroom brands over the years, and being approached by many more, Host Defense remains the only mushroom line we carry.

What sets Host Defense apart begins with control. Every mushroom in their supplements is grown on their own certified organic farm in Washington state, giving them complete oversight from cultivation to finished product. But their true differentiator lies in their approach. While most mushroom brands on the market today build their products around the fruiting body, the visible part of the mushroom, Host Defense harnesses the mycelium, the longest living and most metabolically active part of the organism. Backed by years of research and independent testing, their mycelium-based formulas deliver the immune support and whole body benefits that have made them the number one selling mushroom supplement brand in the country. Their brain support formulas, including Lion's Mane, are consistently among the top selling products in our entire store.

Why we love Host Defense comes down to trust. In a market suddenly crowded with mushroom products chasing a trend, Host Defense stands on decades of genuine science, sustainable cultivation, and a founder whose devotion to fungi predates the fad by a lifetime. That authenticity is why Host Defense has been our go-to for mushrooms for nearly fifteen years.
