Top picks by evidence
- Low evidence3 studies
Across 3 review-level studies, all reported small beneficial effects of Lactobacillus helveticus Rosell-52 on mental health outcomes, though no statistically significant findings were individually noted. The evidence is derived entirely from reviews rather than direct interventional trials, and no specific dose range or study duration was consistently reported. General adult populations were the most common focus, but the lack of primary data limits specificity.
- Very low evidence3 studies
Across 3 review-based studies, all reported beneficial but small-sized effects of Bifidobacterium bifidum Rosell-71 on improved mental health. No studies reported statistically significant findings for this specific strain, and doses, study durations, and forms were not consistently reported.
