maitake
Maitake (Grifola frondosa) is a medicinal mushroom rich in beta-glucan polysaccharides, particularly D-fraction and MD-fraction, which modulate immune function and support metabolic health. Research demonstrates its effects on immune system enhancement, blood sugar regulation, cardiovascular health, and potential anti-cancer properties through immunomodulation and antioxidant mechanisms.
