Combination of immunomodulating mushrooms to support immune function | There are over 20,000 different mushroom species, at least 50 of which have been determined to influence immune responses. The common attribute consistent among these species appears to be the polysaccharides, constituents shown to achieve additional immune system support. Polysaccharides from maitake, reishi, and shiitake are believed to be among the most nutritionally supportive for healthy immune function. Wide-ranging health properties of mushroom supplementation include liver, cardiovascular, healthy glucose metabolism, and cellular health support.
