Mushrooms are edible fungi that are frequently consumed for their nutritional and medicinal benefits.

Furthermore, research shows that the beta-glucans in shiitakes can help increase energy efficiency and lower fat masses, suggesting that supplementing with shiitake can prevent obesity and related metabolic disorders. To experience the benefits of this mushroom without laboring over a stove, many consumers have turned to shiitake mushroom supplements.
