Top picks by evidence
- Low evidence3 studies
Across 3 studies, all reported beneficial effects on gastrointestinal symptoms, with effect sizes ranging from small to moderate. No statistically significant findings were observed. One systematic review (n=1769) showed a small beneficial effect in an ASD population, while two smaller or less-robust studies (a clinical trial and a review) reported moderate benefits in oncological patients and general populations, respectively. The evidence base is too limited to identify a typical dose range.
- Very low evidence3 studies
Across 3 studies, all reported beneficial effects of Enterococcus faecium R0026 on gastrointestinal symptoms, with small to moderate effect sizes. Most evidence comes from reviews, not original trials, and study durations were not consistently reported. No statistically significant findings were identified in any study.
