The new supplement features a blend of mycelium from five mushroom species: Lion's Mane, Reishi, Turkey Tail, Chaga, and Maitake. According to the company, the powder is formulated to assist with cellular health, immune function, and DNA activity across all life stages of domestic pets. The ingredients are sourced from the brand's own cultivation facilities within the Pacific Northwest forests.

Betsy Bullman, president of Host Defense, stated that the move aims to bring their existing mycological expertise to household companions. The product is currently available for purchase through the company's website and select retail partners nationwide. This launch serves as a significant portfolio expansion for the brand, which was founded by mycologist Paul Stamets and has focused primarily on human dietary supplements for over four decades.
