Across 3 studies, all reported beneficial effects of Bifidobacterium plantarum on gastrointestinal health, but effect sizes were uniformly small. No study reported statistically significant findings, and data on dose, duration, form, and population were largely absent. The evidence base is currently sparse and descriptive, limiting confidence in the observed benefit.
Caveats: All three studies are reviews or repository descriptions rather than original controlled trials; none reported effect sizes, doses, or durations. The lack of significant findings and absence of human clinical trial data make the evidence insufficient to draw reliable conclusions about efficacy.
advances in microbiome research have emphasized the fundamental role of probiotics-in addition to their inanimate form, postbiotics, and psychobiotics, a rapidly expanding group of probiotics with psychotropic potential
Bifidobacterium plantarum has been reported to confer health benefits, including improved gastrointestinal health, in consumers.
The Human Microbiota Biobank (HUMB) at University of Tartu, Estonia, was established to support and promote research activities in the field of human microbiota. The collection contains more than 20,000 bacterial strains, both lactic acid bacteria and opportunistic bacteria.
