Talk to your doctor or pharmacist.
Roll Call does not check drug interactions or assess personal safety.
A species of bacteria naturally found in the human gut, especially in infants, cultured and used as a probiotic ingredient in supplements.
Why it’s used
Taken to support gut health, and sometimes marketed for digestive comfort or general immune support.
What the evidence is for
modest digestive or gut-microbiota effects in strain-specific trials.
What the evidence says
NIH ODS material on probiotics notes that effects are strain- and dose-specific. Some clinical trials of particular B. breve strains report modest effects on digestive symptoms or infant gut flora composition, but findings do not automatically generalize to every product simply labeled with the species name.
Context
Clinical trials of probiotic strains typically specify exact strain codes and colony-forming-unit counts rather than mass doses, and outcomes vary by strain, dose, and population studied, such as infants versus adults.
