Important Recomendations

Has anti coagulant effects


The Shiitake-MRL biomass contains the mycelium and primordia (young fruiting body) of the mushroom Lentinula edodes. In comparison to Shiitake extracts, biomass has the advantage of no unwanted shift in effect which occurs with extracts or concentrates, including lyophilisation, and thus the activity of the product corresponds with the source mushroom. The biomass is certified organic in the United States. The biomass form allows for the mushroom enzymes and beta-glucans to be resistant to proteolytic enzymes found in the stomach.


The MRL cultivation system is proprietary allowing for the standardized production of Shiitake in California. With cultivation complete, the biomass powder is sealed in plastic containers and shipped to Holland. In Holland the Shiitake biomass is packed to food grade standards into 500 mg tablets and powder presentations.
