Give your gut a real advantage with Bacillus Coagulans from Swanson Probiotics--the superior, stable, spore- form probiotic that delivers viable nourishment you can depend on for lower GI health and comfort. In the century since Nobel Laureate Elie Metchnikoff first developed the use of beneficial bacteria to bolster human health, researchers have identified hundreds of probiotic species, but one stands apart from the other in terms of viability and efficacy: Bacillus Coagulans. This extraordinary probiotic was first identified in 1933 and demonstrates unique spore-forming capabilities, which give it some distinct advantages over other probiotic species. In its spore phase, this bacterium is able to withstand higher temperatures than common probiotics like L. acidophilus, which greatly increases its shelf- life and eliminates the need for refrigeration. Plus, in spore form the organisms are protected from degradation by stomach acids, enabling them to reach the lower GI tract intact--something many others fail to achieve. Once there, they be active lactic acid producing probiotics, helping to maintain a healthy microbial balance for comfortable gastrointestinal function.
