Mushroom science is very interesting! Grifron Maitake D-Fraction Standard (Tincture) contains purified and standardized "active proteoglucan" from Maitake mushroom (Grifola frondosa) with standard strength. Maiktake D-Fraction is most suitable for regular health maintenance for healthy people. 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. Maitake 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.
Our marketing history shows that Grifron Maitake D-Fraction Standard is very safe and well tolerated. Grifron Maitake D-Fraction Standard 4 oz. bottle contains 3,000 mg of PD-Fraction, which is standardized to contain more than 900 mg (30%) of the active proteoglucan. Grifron Maitake D-Fraction Standard contains no alcohol, sugar, yeast, mold, gluten, dairy products, artificial colors, preservatives, pesticides, herbicides or fertilizers. What is D-fraction? Modern science has identified a unique polysaccharide compound, 1,3 branched 1,6 beta-glucan and 1,6 branched 1,3 beta-glucan in Maitake mushroom, which is the active constituent that support immune cell function.*
Unlike other 1,3 beta-glucans seen in other medicinal mushrooms such as reishi or shiitake, and also in some yeast cells, Maitake's 1,6 and 1,3 beta-glucans have more complex chemical structures with greater degree of branching, which may increase the chances to reach to each immune cell for activation. Maitake D-fraction is the combination of this 1,6 and 1,3 beta-glucans and some protein. It is most effective when taken orally. It is very important that D-fraction is effective in oral administration, because any pure beta-glucan alone is only effective through injection.
