Shiitake mushrooms contain eritadenine, sterols, and beta-glucans - nutrients that are believed to help combat “bad” cholesterol and improve stamina. Shitake may also improve heart health and immune function.
People choose Shiitake as a supplement because these mushrooms also contain amino acids, B Vitamins, Vitamin D, and a range of trace elements including iron, manganese, phosphorus, selenium, potassium, copper, and zinc.
Shiitake also contains a unique polysaccharide known as lentinan, the benefits of which are still under debate in the scientific community.
