ABOUT HOST DEFENSE® MUSHROOMS™

Host Defense® Mushrooms™ is a U.S.-based functional mushroom supplement brand founded by mycologist Paul Stamets. Developed by Fungi Perfecti, the company draws on decades of mushroom cultivation, mycology, and ecological research.

Based in Washington State near the Olympic Peninsula, Host Defense focuses on connecting human health with the broader ecological role of fungi. Its philosophy extends beyond supplementation to the ways fungi interact with forests, soil, pollinators, and natural ecosystems.

The brand offers single-mushroom and multi-mushroom formulas in capsules, powders, extracts, and other convenient formats for everyday wellness routines.

THE HOST DEFENSE® APPROACH

Host Defense has built its identity around mushroom biology and the importance of the whole fungal life cycle.

Rather than viewing mushrooms simply as isolated ingredients, the company emphasizes the complex compounds produced by fungi throughout their development.

Its formulas may utilize mushroom mycelium and other fungal components depending on the individual product.

This approach distinguishes Host Defense from brands that focus exclusively on fruiting-body extracts.

WHAT IS MUSHROOM MYCELIUM?

Mycelium is the vegetative network of a fungus. It consists of microscopic branching structures called hyphae that grow through and interact with their surrounding environment.

The visible mushroom is the reproductive fruiting structure of certain fungi, while the mycelium represents another major part of the organism.

Different mushroom supplements may therefore use:

• Fruiting bodies

• Mycelium

• Extracts

• Cultured mushroom materials

• Combinations of fungal components

These preparations are not necessarily interchangeable, so consumers should compare the specific ingredients and serving amounts listed on individual products.

FUNGI PERFECTI® & PAUL STAMETS

Host Defense® Mushrooms™ is produced by Fungi Perfecti, a company founded by mycologist Paul Stamets.
