Bioavailability - The immune-supporting polysaccharides common to all medicinal mushrooms and mushroom mycelium are found inside of the cell walls. However, the cell walls are made from an indigestible fiber called "chitin", the same material a lobster shell is made of. Hot water extraction is the only clinically validated method for breaking these polysaccharides out of the indigestible cell walls. Even soft mushrooms like shiitake are prepared as a hot water extract or a tea when used medicinally.
Concentration - The immune supporting polysaccharides found in the cell walls of mushrooms and mushroom mycelium comprise only 0.5-2% of the total mass by dry weight (depending on the mushroom), not enough to have effect even if they were bioavailable. Most hot water mushroom extracts are at least a 20:1 concentration. Hot water extraction dissolves the indigestible fiber (chitin), allowing the fiber to be removed from the extract when the water is removed. This process concentrates the polysaccharides to the effective levels (30%) identified in the published research.
Dual extracts (dehydrated) are 50-80 times more potent than mycelium biomass.
