Cultivation Process of Shiitake-MRLTM

MRL Ltd.´s Lentinula edodes powder contains both mycelium and primordia (young fruit body) cultivated into a biomass that is grown on a sterilised (autoclaved) substrate.
This cultivation process ensures the powder is free from contamination by other fungi and that pesticides and heavy metals are absent.

The cultivation system is proprietary, allowing for standardised production of Lentinula edodes. The powder biomass is then sealed in plastic containers.

Manufacturing Process of Shiitake-MRLTM

The Lentinula edodes is processed under the same rigorously controlled conditions that are applied to the manufacture of a conventional pharmaceutical. This ensures that each tablet contains 500g of the standardised Shiitake 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: USA/EU
The fungal biomass Lentinula edodes that comprises Shiitake-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).
