Grifron®-Pro Maitake D-Fraction® (Tincture) contains purified and standardized "active proteoglucan" from Maitake mushroom (Grifola frondosa) with professional strength.
The "Grifron®-Pro" products are the most purified and concentrated version among our D-Fraction line.
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.
Grifron®-Pro Maitake D-Fraction® has been the subject of many clinical and non-clinical studies in the US, Japan and other countries. It was honored to be referred to by many prominent healthcare professionals in their books and articles repeatedly. Our studies and marketing history show that it is very safe and well tolerated.
Grifron®-Pro Maitake D-Fraction® 1 oz. bottle contains 3,000 mg of PD-Fraction, which is standardized to contain more than 900 mg (30%) of the active proteoglucan.
(Please note that other maitake extract products on the market contain no more than 1,000 mg of crude extracts in 1 oz. Further, the levels of active substances in such crude extracts have never been disclosed.)
Grifron®-Pro Maitake D-Fraction® contains no alcohol, sugar, yeast, mold, gluten, dairy products, artificial colors, preservatives, pesticides, herbicides or fertilizers.
