Across 3 studies, all reported beneficial but small effects for improved gastrointestinal health with Bifidobacterium plantarum. No doses, forms, or durations were consistently reported, and none of the included studies reached statistical significance. The evidence base is too limited to draw firm conclusions.
Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). Many of the included studies did not reach statistical significance — effect may be smaller than the predominant direction suggests. Additionally, the studies are reviews or a collection description, not original trials.
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.
