While other mushrooms products are mycelium (a lab-grown fungus that's only part of a mushroom), Four Leaf Rover Immunity contains the fruiting body and the mycelium.
Mycelium is grown on grains like oats, sorghum or rice, not on wood where mushrooms would grow in nature. Mycelium products contain significantly lower levels of valuable beta-glucan, the active medicinal compound in mushrooms. Your dog deserves Four Leaf Rover's REAL mushrooms ... grown the way nature intended and complete with all their health-boosting properties.
