Top picks by evidence
- Low evidence3 studies
Across 3 review-level studies, all report beneficial effects on gastrointestinal symptoms, with effect sizes ranging from small to moderate (two studies show moderate, one shows small). However, these reviews evaluate probiotics in general, not specifically Bifidobacterium animalis subsp. lactis LAFTI B94, and no primary RCTs with statistically significant findings were identified. The most studied population is athletes and recreationally active adults, but dose range and duration are not reported.
- Low evidence3 studies
Across 3 studies, all reported beneficial effects of Lactobacillus plantarum LP01 on reducing gastrointestinal symptoms, with 2 studies showing statistically significant findings and effect sizes ranging from small to moderate (predominantly moderate). The evidence is drawn from populations undergoing digestive surgery or bowel preparation, with no consistent dose or duration data available.
- Low evidence3 studies
Across 3 studies (2 systematic reviews/reviews and 1 RCT), 2 reported beneficial moderate-sized effects of Lactobacillus helveticus L10 on reduced gastrointestinal symptoms, while 1 small neutral RCT found no differences. All studies involved athletic or recreationally active adult populations, and no consistently reported dose ranges, durations, or forms were available. Evidence is preliminary and limited by the small number of studies and lack of statistically significant findings.

- Very lowBifidobacterium plantarumAcross 3 review papers, all report beneficial moderate-sized effects of Bifidobacterium plantarum (as part of probiotic supplementation) on reducing gastrointestinal symptoms. Evidence is drawn from general populations, athletes, and patients with chronic kidney disease, though no individual trial data or effect sizes are reported within these reviews. Doses, study durations, and forms were not extractable from the available data.3 beneficial3 studies
