[tab name="Overview"]

Like other polypores, Maitake contains polysaccharides that stimulate the immune system. As well as being identified to enhance the immune system, research has also indicated that whole Maitake may regulate blood pressure, glucose, insulin, and both serum and liver lipids, such as cholesterol, triglycerides, and phospholipids. One active constituent in Maitake for enhancing the immune activity was identified in the late 1980s as a protein-bound beta-glucan compound.
