Technical View on D-fraction: D-fraction is a highly standardized and purified beta-1,6 glucan (1,6 main chain with 1,3 branches in its chemical structure) and beta-1,3 glucan (1,3 main chain with 1,6 branches in its chemical structure)with about 30% of protein, extracted from Maitake mushroom fruit body. D-fraction has the unique polysaccharide compound. The degree of branching is greater than that of 1,3 beta-glucan often found in other medicinal mushrooms. Researchers theorize that the complexity of branching may make Maitake superior to other beta-glucan products. An essential fact about the D-fraction is that it is effective when consumed orally.

Some of the recent studies indicates that D-fraction is possibly useful in conjunction with conventional chemotherapeutic agents, by not only improving the agent's positive benefits, but it also aids in the amelioration of many of the side effects of the agents.
