LactoSpore (Bacillus coagulans) is a shelf-stable probiotic which when ingested, can withstand the acidic environment of the stomach. These spores then germinate and proliferate within the GI tract. After germination, B. coagulans is metabolically active as part of facultative anaerobes in the intestine, producing lactic acid, as primary product of fermentation. The main mechanism of survival is competitive exclusion. B. coagulans is a temporary resident of GI tract: following discontinuation of its administration, it is slowly excreted from body (within seven days). LactoSpore® may be chosen as the probiotic of choice for several reasons including history of use, stability of spores, Generally Recognized As Safe (GRAS) status, documented clinical effectiveness and potential health benefits (normalizing intestinal flora/immune enhancement and non-GI tract conditions). Fructooligosaccharides (FOS) present in this product function as a prebiotic (food for probiotic).
