Introducing Swanson Probiotics ProDURA™ Bacillus Coagulans—the indestructible probiotic. When it comes to probiotic supplementation, Bacillus coagulans has several advantages over other species. As a spore-forming bacterium, it is able to survive at higher temperatures, eliminating the need for refrigeration and greatly increasing its shelf life. More importantly, the spores’ protective coating shields them from destruction by bile and stomach acids until they meet the perfect conditions of temperature, moisture and pH found in the large intestine, where they become active lactic acid-producing probiotics.ProDURA is produced by Nebraska Cultures Inc., the industry leader in probiotic quality and stability. In a University of Nebraska-Lincoln study comparing the heat resistance of three leading commercially available Bacillus coagulans strains, ProDURA was approximately twice as durable as the other strains tested. In fact, ProDURA’s remarkable stability shows no loss in potency at room temperature for three years, and it can withstand near-boiling temperatures with almost no decrease in effectiveness.With 2 billion colony-forming units per serving, our ProDURA™ Bacillus Coagulans vegetarian DRcaps® are a great way to help maintain a favorable microbial balance for your intestinal health and comfort. Innovative DRcaps withstand stomach acid for slow release within the lower GI tract where probiotics flourish. And of course, like all Swanson® products, they’re backed by our 100% satisfaction, money-back guarantee.
