What they do
Host Defense grows mushroom mycelium on certified-organic substrates at the Stamets [[farm|family farm]] in Washington State and produces the resulting biomass as supplements across formats — capsules, powders, liquid extracts, gummies. The catalog covers the major medicinal species: reishi, [[lions-mane|lion’s mane]], turkey tail, chaga, cordyceps, agarikon, maitake, plus species-specific blends targeting immune, cognitive, respiratory, and other functions.
Why it’s listed
[[paul-stamets|Paul Stamets]] is one of the most visible mycologists on Earth, and Host Defense is the operational form of his lifetime body of work — research, agar plates, fruiting chambers, supplement bottles, all on one farm. The directory cares about mycology because mushrooms are a substrate-builder layer the food and medicine systems have barely begun to use. Host Defense is the consumer-scale anchor for that whole conversation.
