Mycology Research Labs
United Kingdom based, MRL was founded in 1997 and develops mycology (mushroom nutrition) and non-mycology products as dietary supplements or 'functional foods'. MRL utilises proprietary Japanese production technology to cultivate selected strains of the different mushrooms in California. The strains have been selected for their overall bioactivity and for their stability (purity).
These mushroom nutrition products are not extracts, but instead contain both the mycelium and primordia (young fruitbody) of the mushroom cultivated into a biomass on an edible, sterile (autoclaved substrate). Advantages over an extract are that we supply not only beta-glucans but also enzymes and secondary metabolites. Furthermore, the biomass protects the beta-glucan content from the proteolytic enzymes in the gut.
The cultivation process ensures that the biomass is free from contamination by other fungi or bacteria and that heavy metals (pesticides) are not present. Following cultivation, the biomass is dried, powdered and tableted to food grade Good Manufacturing Practice (GMP) standards.
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)
