No trial of this product was found. Bacillus coagulans dog trials exist only for strain GBI-30, 6086 (PMIDs 40831181, 41304148, 33940614), which the label does not name.
What the label discloses
The brand page lists a proprietary blend of Bacillus coagulans, B. clausii and B. subtilis at 3 billion CFU per chew with FOS 100 mg, GOS 100 mg and a 75 mg postbiotic yeast blend. The Amazon listing read on the same day lists an eight-strain blend (B. coagulans, L. reuteri, B. bifidum, B. longum, L. brevis, L. casei, L. plantarum, S. thermophilus) with pumpkin, honey, inulin and FOS, so the formulation in circulation should be checked on the physical label. Inactive ingredients on Amazon include dried whey, pork gelatin, pork liver and salmon oil.
