Maitake mushroom (Grifola frondosa) is an edible tasty mushroom prized in Asian countries for centuries. Since the 1980s Maitake mushroom became a subject of scientific studies, and researchers found that it supports healthy immune functions, healthy blood glucose levels and healthy blood pressure in laboratory animals.*

The active proteoglucan, often referred to as D-fraction by scientists, is a unique beta-glucan conjugated with protein, which has been identified and isolated as a responsible substance for potent immune-activating property of Maitake mushroom.*
