Mushroom Immune Support At It’s Peak Potential. For the last 5000 years, Chinese herbalists have processed mushroom fruiting bodies via hot water extraction for tonic immune support. Based on extensive HealthForce research, the fire-enhanced extraction process is essential in order to break down the tough, fibrous cell walls in mushrooms and thus render the beta-glucans (compounds which support the immune system) bioavailable. Fire-enhanced mushroom extracts are vastly superior to raw mushrooms. Some things are best raw and some things need to be enhanced by fire. HealthForce knows the difference! HealthForce Myco-Immunity contains fire-enhanced extracts of four different wood-grown mushroom fruiting bodies specifically chosen for theirpurity and immune supporting properties.
