Across 3 studies, all reported beneficial moderate-sized effects of Lactobacillus plantarum LP01 (administered in combination with other probiotic strains) on improved stool formation. The evidence primarily comes from large outpatient populations, including individuals undergoing digestive surgery or bowel preparation and those with chronic intestinal disorders, with doses reported as 1 billion living cells/day in one study. However, the evidence base is small and conclusions should be considered preliminary.
- Effective dose range: 1 billion living cells/day
- Studied populations: outpatients undergoing digestive surgery, outpatients with chronic intestinal disorders, outpatients undergoing bowel preparation
Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). All studies tested a multi-strain formulation, so the specific contribution of Lactobacillus plantarum LP01 alone cannot be isolated.
