Support your dog’s immunity and longevity with beta-glucans: Whole mushrooms are the richest source of beta-glucans, which help activate the immune cells responsible for trapping and eliminating harmful foreign particles in the body. Overall, it provides powerful immune support and helps increase your dog’s chances for a long and happy life. Grown on wood, not on grains: Most mushroom products are grown on oats or rice, but ours are grown on wood, the way nature intended. As a result, they are rich in beta-glucans. Most mushroom powder products use mycelium grown on oats or rice, but it’s easy to spot them because they're light brown in color, not the dark-rich cocoa color of real mushrooms.
