Gas. Bloating. Bad breath. Diarrhea. Constipation. BioDIGEST helps tackle the root cause of these problems by acting as a foundation for intestinal health. BioDIGEST is a plant-based probiotic and prebiotic, digestive, and immune system support formula in a lignan-rich base. BioDIGEST helps maintain proper gut pH, intestinal health, and flora in the digestive tract. Most human probiotic strains are not acid-resistant enough to survive the digestive tract of cats and dogs so using a clinically proven, acid-resistant strain like BioDIGESTs Pediococcus acidilactici is essential to get the benefits and results pets need. Does not contain any artificial: flavors, colors, preservatives, or binders.
