New evidence
Probiotic Bacillus coagulans increased bowel movements and improved stool consistency in a 111-person trial — but it’s one of the first solid studies on this specific pairing.
This is an early, well-designed trial suggesting the probiotic helps with constipation and bowel regularity, but a single study — even a rigorous one — isn’t enough to call the effect established.
In a randomized, double-blind trial of 111 healthy adults in China who had mild digestive complaints, those taking the probiotic Bacillus coagulans GBI-30, 6086 reported more frequent bowel movements and firmer, healthier stool consistency compared to the placebo group. The changes were statistically significant, but because this is among the first indexed studies on this specific probiotic and outcome, the findings should be considered promising rather than conclusive.
Where this fits in the evidence
This is among the first studies we've indexed on Bacillus coagulans GBI-30, 6086 for Improved Gastrointestinal Function — treat it as an early signal until more research accumulates.
