Across 3 review papers, all reported beneficial effects on gut health, with effect sizes ranging from small to moderate (predominantly small). No original clinical trials were included; the evidence is entirely from literature reviews, and no dose, duration, or population data were available. The only specific finding was from a review noting increased fecal lactobacilli and bifidobacteria and reduced clostridia and enterobacteria.
Caveats: Evidence base is small (only 3 studies) and consists entirely of review articles, not original clinical trials — conclusions should be considered preliminary. None of the studies reported statistical significance, so the observed beneficial effect may be smaller than suggested. Additionally, available evidence is overwhelmingly positive, which raises concern for publication bias (null-result studies are less likely to be published or indexed).
Lactobacillus fermentum HA-179... was shown to improve gut health in the literature reviewed
The consumption of probiotics in the context of a balanced diet through the consumption of functional foods or through the intake of pharmaceutical preparations has proven to contribute to the improvement of human health, even contributing to the prevention of diseases.
Lactobacillus fermentum HA-179 was found to increase the amount of fecal lactobacilli and bifidobacteria, while reducing the number of fecal clostridia and enterobacteria, indicating a beneficial effect on gut microbiota.
