Polyporus-MRL is derived from a master strain of Polyporus umbellatus. The powder contains both mycelium and primordia (young fruit body) cultivated into a biomass that is grown on a sterilised (autoclaved) substrate.
Cultivation Process of Polyporus-MRL
MRL Ltd.´s Polyporus umbellatus powder contains both mycelium and primordia (young fruit body) cultivated into a biomass that is grown on a sterilised (autoclaved) substrate. The cultivation system is proprietary, allowing for standardised production of Polyporus umbellatus. The powder biomass is then sealed in plastic containers.
Manufacturing Process of Polyporus-MRL
The Polyporus umbellatus is processed under the same rigorously controlled conditions that are applied to the manufacture of a conventional pharmaceutical. This ensures that each tablet contains 500 mg of the standardised Polyporus product. The tablets are film coated to protect them from moisture, thus preserving the quality of the product and ensuring a long shelf life. After passing quality control testing the tablets are released for use. The choice of additives used in manufacture renders these tablets suitable for Kosher or vegetarian use.
Certified Organic
The fungal biomass Polyporus umbellatus that comprises Polyporus MRL is certified 100% Organic in the United States by Quality Assurance International (Certificate No. 103491-A). In December of 2005, MRL powder gained EU organic certification in accordance with EU Council Regulation (EEC) No. 2092/91 by Quality Assurance International (Certificate No. 105493-A).
