Lactobacillus plantarum UALp-05M

What does the research say about Lactobacillus plantarum UALp-05M?

2 health outcomes synthesised

Lactobacillus plantarum UALp-05M has been studied for 2 health outcomes: improved growth performance and reduced inflammation levels. The strongest evidence, though preliminary, is for improved growth performance, supported by 4 studies that all reported beneficial effects with large effect sizes. The research on this probiotic strain has been conducted entirely in animals (livestock, aquaculture, and laboratory models) — no human studies are available, so relevance to human health is uncertain.

Strongest evidence: The only area with research is improved growth performance, where all 4 studies (in broiler chickens, weaning pigs, young piglets, and juvenile fish) reported beneficial effects, with 3 reaching statistical significance. Effect sizes were predominantly large. No consistent effective dose or duration was reported across these studies. The evidence strength is rated low due to the small number of studies and the fact that all were conducted in non-human species.

Mixed or weaker evidence: Reduced inflammation levels has been studied in 3 studies (cell lines, mice, intestinal epithelial cells), all reporting beneficial effects with moderate-to-large effect sizes — including statistically significant inhibition of IL-6, IL-8, and TNF-α, and increased IL-10. Evidence strength is very low because the evidence base is small, doses were not reported, and all studies were non-human.

Effective dose patterns: No consistent dose information is available from either synthesis. Doses and durations were not systematically reported, preventing any dose-response conclusions or cross-cutting comparisons.

Population insights: All studies were conducted in animal models — broiler chickens, weaning pigs, young piglets, juvenile fish, mice, and intestinal epithelial cell lines. No human populations have been studied, so population-specific insights (e.g., age, health status, deficiency) are absent.

Notable caveats: The clinical literature in both areas is susceptible to publication bias — null-result studies are less likely to be published. The evidence bases are small (4 and 3 studies, respectively). Most critically, no human trials exist for either outcome, so the relevance to human growth or inflammation is unknown. Conclusions should be considered preliminary.

Frequently asked

  • What is Lactobacillus plantarum UALp-05M good for according to research?
    Research on Lactobacillus plantarum UALp-05M has focused on two outcomes: improved growth performance and reduced inflammation levels. In all 4 studies on growth performance (in animals like broiler chickens, piglets, and fish), beneficial effects were observed. All 3 studies on inflammation (in cell lines and mice) also reported reductions in inflammatory markers. However, all studies were non-human, so applicability to humans is uncertain.
  • What dose of Lactobacillus plantarum UALp-05M is typically used in studies?
    No consistent or reproducible dose information is available from the current research. Doses and study durations were not reported in most studies, or varied too much to allow any dose-related conclusions. This means no supplementation guidance can be derived from the evidence.
  • Who benefits most from Lactobacillus plantarum UALp-05M?
    All studies to date have been conducted in non-human species — broiler chickens, weaning pigs, young piglets, juvenile fish, mice, and intestinal epithelial cell lines. No human populations have been studied, so it is not possible to identify which human groups might benefit most.
  • Are there caveats or limitations in the research on Lactobacillus plantarum UALp-05M?
    Yes, several major limitations exist. The evidence base is small (only 4 studies for growth, 3 for inflammation). All studies were performed in animals or cell models, not humans — human relevance is unknown. Publication bias is a concern, as null results are less likely to be published. Evidence strength is rated low to very low, meaning conclusions are preliminary.
  • Does Lactobacillus plantarum UALp-05M help with improved growth performance?
    Across 4 animal studies, all reported beneficial effects of Lactobacillus plantarum UALp-05M on growth performance, with 3 studies reaching statistical significance. Effect sizes were predominantly large. However, because the research was conducted in livestock and aquaculture species — not humans — it is unclear whether similar effects would occur in people.
  • Does Lactobacillus plantarum UALp-05M help reduce inflammation?
    Three studies (cell-based and mouse models) all reported beneficial effects on reducing inflammation, with effect sizes ranging from moderate to large. One cell experiment found significant inhibition of IL-6, IL-8, and TNF-α, and increased IL-10. However, evidence is very low strength due to the small number of studies and lack of human data, so no firm conclusions can be drawn.
