- Low evidence3 studies
Across 3 review-level studies (no original RCTs), all reported small beneficial effects of Lactobacillus helveticus Rosell-52 on mental health outcomes in adult humans. No statistically significant findings were documented in the database, and no specific dose, form, or duration data were extracted. Effects were consistently small in magnitude.
- Very low evidence3 studies
Across 3 studies (all reviews), beneficial small-sized effects were reported for Bifidobacterium bifidum Rosell-71 on mental health outcomes, though none of the findings reached statistical significance. Doses and study durations were not consistently reported, and the evidence comes entirely from general reviews of probiotics rather than direct interventional trials on this specific strain.
