Bifidobacterium bifidum Rosell-71
What does the research say about Bifidobacterium bifidum Rosell-71?
4 health outcomes synthesisedBifidobacterium bifidum Rosell-71 has been studied in four distinct health outcome areas, with the most researched being depressive symptoms, where 4 studies suggest beneficial effects. The strongest evidence, though still preliminary, points toward moderate effects on depression and cognitive function in adults with psychiatric disorders. No specific effective dose or form has been consistently reported across the available research.
Strongest evidence: The most robust findings are for depressive symptoms and reduced depression symptoms, both rated as low evidence strength. Across 4 studies (all reviews or meta-analyses), a moderate beneficial effect was reported, with one 2025 meta-analysis showing a statistically significant reduction (SMD -0.55; p=0.03). Cognitive function also shows a large effect (SMD -0.90; p=0.01) in one meta-analysis of adults with depression, but the evidence strength is very low due to the small number of studies.
Frequently asked
What is Bifidobacterium bifidum Rosell-71 good for according to research?
Research has explored its effects on depressive symptoms, cognitive function, and overall mental health. The most studied outcome is depressive symptoms, where 4 of 4 studies report beneficial effects (low evidence strength).What dose of Bifidobacterium bifidum Rosell-71 is typically used in studies?
No specific dose, form, or study duration was consistently extractable from the available research. As a result, no evidence-based dose range can be determined from the current syntheses.Who benefits most from Bifidobacterium bifidum Rosell-71?
The available evidence primarily comes from adults with psychiatric disorders (e.g., depression) and cognitive conditions. Limits in the data—such as pooling of multi-strain formulations—make it difficult to isolate who benefits most from this specific strain alone.Does Bifidobacterium bifidum Rosell-71 help with cognitive function?
Two of 3 studies reported beneficial effects on cognitive function, with one 2025 meta-analysis in adults with depression showing a large, statistically significant effect (SMD -0.90; p=0.01). However, evidence strength is very low due to the small number of studies and lack of dose and duration reporting.Are there caveats or limitations in the research on Bifidobacterium bifidum Rosell-71?
Yes: the evidence base is small for all outcomes (3–4 studies each), and most studies are reviews or meta-analyses rather than direct trials of this specific strain. Effects may be confounded by multi-strain formulations, and publication bias is a concern since null-result studies are less likely to be indexed.How strong is the evidence for Bifidobacterium bifidum Rosell-71 on mental health?
Evidence for improved mental health is very low across 3 studies, all of which reported beneficial but small effects that did not reach statistical significance. No specific dose, form, or population data were extractable.
