Description
Maitake Pro-D by mushroom wisdom is a professional strength tincture that contains the active proteoglucan D-fraction from Maitake mushrooms. Our “Pro” products are the most concentrated within our D-Fraction® line.
The Maitake mushroom (Grifola frondosa) is prized in Asia for its significant health benefits. Maitake contains a unique, protein-bound Beta-1,3 glucan and Beta 1, 6 glucans that scientists call “D-fraction.” Research at leading university medical centers demonstrates that D-fraction is a powerful immune support nutrient that may help support the overall functioning of the immune system.
Maitake D-Fraction Pro® has been the subject of many clinical and non-clinical studies in the US, Japan and other countries. Our studies and marketing history show that it is safe and well tolerated.
