Probiotics are the beneficial bacteria that live in your digestive tract and help maintain overall digestive and immune health. The Problem: Many probiotics can't survive the harsh acidic environment of the stomach. Probiotics that fail to reach the intestinal tract alive are less able to provide digestive and immune health benefits there. The Solution: Schiff Sustenex contains a unique strain of probiotic called BC30. BC30 is protected by an outer layer of natural organic material, which allow to better withstand the acidic environment of the stomach and take its place in both the small and large intestine where it can promote healthy digestive and immune health. Schiff Sustenex helps lessen abdominal discomfort and bloating and may help relieve occasional diarrhea. The Prolific Probiotic: Along with being prolific colonizers, studies are revealing that BC30, the probiotic bacteria in Schiff Sustenex, have much higher survival rates than some other probiotic capsules, pills and yogurts.
