In this randomized clinical trial, probiotics in differing potencies were given to patients on antibiotic therapy. The severity of digestive side effects from the antibiotic – bloating, cramping, and diarrhea – were measured in the groups receiving high dose antibiotics, low dose antibiotics, and no probiotics.
The group receiving high dose probiotics were almost 50% less likely to have diarrhea than the group who did not take probiotics after antibiotic therapy.
The researchers concluded:
“The tested four strain probiotic combination appears to lower the risk of antibiotic-associated diarrhea and gastrointestinal symptoms in a dose-dependent manner in adult in-patients.”
