Bacillus coagulans is a shelf-stable probiotic that helps the body to restore healthy flora in the gastrointestinal system. B. coagulans passes through the stomach in its spore form and upon arriving in the duodenum, germinates, multiplies rapidly and becomes metabolically active in the intestines producing lactic acid (right spinning). This form of probiotic helps normalize pH, inhibits pathogenic bacteria growth and is especially useful in cases of diarrhea.
