Cultivation Process of Maitake MRL
This  Grifola frondosa is not a mere extract of Grifola frondosa. The tablets  contain both mycelium and primordia (young fruit body) cultivated into a biomass that is grown on a sterilized (autoclaved) substrate.

This cultivation process ensures the powder is free from contamination by other fungi and that pesticides and heavy metals are absent.

Grifola frondosa The cultivation system is proprietary, allowing for standardized production of Grifola frondosa. The powder biomass is then sealed in plastic containers.

Manufacturing Process of Maitake MRL
Our Grifola frondosa 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 standardized Grifola 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.

All products are manufactured to pharmaceutical GMP standards in the United Kingdom (ML 10324).
