For more than 2,000 years, Chinese herbalists have valued reishi as one of nature's premier tonic mushrooms for enhancing immune function and general vitality. We now know that reishi mushrooms have unique polysaccharides and triterpenes that support the body's defenses at the cellular level. But, while both of these components have been found to be important to reishi's benefits, most extracts are standardized to only one or the other. Super Potent Reishi Mushroom Complex from Swanson Superior Herbs features an advanced, double- standardize extract guaranteed to contain a minimum 15% polysaccharides. Furthermore, the highest concentrations of these health- promoting compounds are normally locked inside the reishi spores, which have a remarkably tough outer shell. That makes it difficult to obtain all the benefits from consuming the whole mushroom itself; yet the fibers and other components not found in concentrated extracts provide additional nutritive benefits. That's why our Super Potent Reishi Mushroom Complex includes whole reishi spores gently processed to break the shell walls. Our shell-broken spores deliver the added value of the whole mushroom with the potential to release even more active phytonutrients.
