- Low evidence3 studies
Across 3 studies, all 3 reported beneficial moderate-sized effects of Bifidobacterium plantarum on reducing gastrointestinal symptoms. The evidence is drawn from review articles covering varied populations, including patients with chronic kidney disease, athletes, and general populations, but lacks information on specific doses, forms, or study durations.
- Low evidence3 studies
Across 3 studies (all reviews), 3 reported beneficial moderate-to-small effects of Bifidobacterium animalis subsp. lactis LAFTI B94 on reducing gastrointestinal symptoms in athlete or recreatively active populations. The predominant effect size is moderate, though one review reported a small effect. No dose or form data were reported, and study durations were not consistently available.
- Low evidence3 studies
Across 3 studies, all reported beneficial effects of Lactobacillus plantarum LP01 on reducing gastrointestinal symptoms, with moderate effect sizes in 2 studies and a small effect in the third. Two of the three studies found statistically significant improvements. The evidence primarily comes from clinical populations undergoing digestive surgery or bowel preparation, using a probiotic mixture containing LP01 at a dose of 1 billion living cells/day in one study.
