Buying Guide
Extraction Method: Mycelium vs Fruiting Body
The primary difference between Host Defense and Real Mushrooms lies in what part of the mushroom they use. Host Defense grows its mycelium on organic brown rice substrate, creating a matrix of mycelium and fermented grain. This method yields a broader spectrum of beta-glucans and other active compounds. Real Mushrooms, on the other hand, extracts only the fruiting body, which is the mushroom cap and stem. Each approach has its advocates. For those who prefer a whole-food-based mycelium product, Host Defense offers a unique option.

Frequently Asked Questions
