Shiitake mushroom is one of the five most cultivated edible mushrooms in the world, having been highly recognized in Far Eastern countries (e.g. Japan, China and Korea) as a food and recipe for well-being for thousands of years. In 199 AD, Kyusuyu, a native tribe of Japan offered the Japanese Emperor Chuai a Shiitake mushroom (Lentinus edodes), because of its properties that: “accelerated vital energy, satisfied hunger, benefited the body and defeated the body's fluid energy.” MARNYS® ?-glucanforte Shiitake is an ideal food supplement for those who want to maintain their physical well-being in demanding situations.
