Mushroom Gold is based on three edible mushrooms – organic Maitake, Reishi and Shiitake. Rich in Vitamin D*, these mushrooms have been used for centuries to help support a healthy ecosystem. We ensure that the fruiting body and mycellium as well as the extra-cellular metabolites are blended to deliver the concentrated polysaccharides and beta-glucans. This broad-spectrum formula contains the highest organic grade, sustainably cultivated herbs, carefully selected to boost your wellbeing with nature’s goodness. *Each daily serving gives you: 248% NRV of Vitamin D naturally occurring in mushrooms. Vitamin D contributes to the normal function of the immune system and process of cell division.
