M/R/S Mushroom Formula provides a dynamic combination of maitake, reishi and shiitake mushrooms to promote exceptional antioxidant support for the maintenance of daily wellness. There are over 100000 different mushroom species, only 10% of which have been identified and investigated by researchers. The common attributes consistent among these species appears to be the polyphenols and polysaccharides, constituents shown to provide high antioxidant support. In a preclinical study investigating the composition of a number of mushroom species, maitake, reishi, and shiitake were found to contain high levels of phenolic compounds and polysaccharides. Furthermore, these mushrooms were among the most supportive for enhancing antioxidant activity. M/R/S Mushroom Formula also provides vitamin C for additional antioxidant support.
