Cultivation Process of Pleurotus MRL™
Mycology Research Laboratories Ltd.´s Pleurotus ostreatus, is grown on a sterilised (autoclaved) substrate and 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).
The cultivation system is proprietary, allowing for standardised production of Pleurotus ostreatus.
MRL mushrooms biomass offers a mixture of many co-operating and co-related healthful bioavailable ingredients prepared by nature itself – it is thus a truly pure natural product.
After cultivation the Pleurotus ostreatus is then manufactured in the Netherlands into 500 mg tablets and in various powder forms to FSSC 22000 (Version 4.1) standards.
Veterinary products are manufactured under veterinary registration number (NL217476).
Moreover, all powder presentations are produced and manufactured in accordance with both EU and UK organic standards.
