The latest research in human and animal medicine points to the gut being responsible for more than 80% of the immune system! The main component of a healthy gut is the friendly bacteria that live there (probiotics). This bacteria combats bad bacteria. They are the gatekeepers that stop intruders and keep the mucosal lining healthy so the body receives its vital nutrition.These “good soldiers” need to be able to have the proper fertilization in order to set up a colony and continue to produce and repopulate. Essentially, you need to feed the probiotics. This happens by giving a prebiotic.Probiotics are not nearly as successful at reproducing and flourishing without the help of a prebiotic. Love Bugs encourages the growth of friendly bacteria to protect the gut for cats and dogs. Contains 14 strain probiotic with 30 billion allergen-free CFU.
