Digestive enzymes play a crucial role in breaking down yeast biofilm, a protective layer that yeast cells create to shield themselves from the immune system and yeast treatments. Enzymes such as protease and cellulase, can degrade the components of biofilm, exposing yeast cells to the immune system and making them more susceptible to the ingredients in Yeast Guard. Digestive enzymes also ensure that undigested food particles, which can feed harmful bacteria and yeast, are minimized, thereby supporting the growth of beneficial gut flora. This dual action of breaking down biofilms and promoting nutrient absorption helps in maintaining a healthy gut environment in dogs with yeast issues.
