The Science

科学

Our dual hot water + ethanol extraction process unlocks both water-soluble beta-glucans and alcohol-soluble triterpenes, delivering the full spectrum of bioactive compounds.

Every batch is independently tested for purity, potency, and heavy metals. We publish results because transparency isn’t optional — it’s foundational.

We use 100% fruiting body extracts, never mycelium-on-grain. The difference matters: fruiting bodies contain up to 15x more beta-glucans than mycelium.
