In addition to taking steps to ensure purity and a high constituent content, we are also concerned about providing mushroom products in which the constituents are in a bioavailable form. The main constituents of mushrooms, the 1,3-Beta Glucans, are tightly bound to the cell walls and have a low degree of bioavailability in raw mushrooms. To overcome this and increase the bioavailability of the constituents, all of our mushrooms undergo a steam activation process that breaks down the cell walls and frees the 1,3-Beta Glucans from the chitin.
