Synergistic Anti-Helicobacter pylori Effects of Takifugu obscurus Skin Peptides and Lactobacillus plantarum: A Potential Gastric Health Dietary Supplement.

Our assessment

This 2025 study investigated a potential dietary supplement for gastric health by combining two natural compounds. Researchers tested the antibacterial activity of Takifugu obscurus (pufferfish) skin peptides and a cell-free supernatant from Lactobacillus plantarum WUH3 against Helicobacter pylori. The study design was laboratory-based, meaning it did not involve human participants, so no sample size, duration, or participant demographics are available. This is a preclinical study that evaluates a concept, not a clinical trial on people [Data not available].

How it works

The researchers found that the combination of pufferfish skin peptides and the Lactobacillus supernatant worked together to fight H. pylori bacteria. The key finding was a synergistic antibacterial effect, meaning the combined ingredients were more effective than either one alone. For you, this suggests that a dietary supplement made from these compounds might one day offer a new, non-antibiotic approach to managing H. pylori infections, which are a common cause of stomach ulcers and gastritis. However, since this is a laboratory study, it does not yet show how this would work in the human body [Data not available].

Safety profile

Data not available. This study did not provide any information on side effects, adverse events, or safety reports for the compounds tested. No FDA adverse event data was provided for Takifugu obscurus skin peptides or Lactobacillus plantarum supernatant FDA FAERS ↗. No safety information from the NIH ODS or NIH DSLD was included NIH ODS ↗ NIH DSLD ↗.

Our recommendation

This research is at a very early, preclinical stage. The findings are promising for developing a new dietary supplement, but they do not support any current use for treating H. pylori in humans. Do not attempt to use pufferfish skin peptides or Lactobacillus preparations for this purpose, as safety and effectiveness in people have not been established. If you have an H. pylori infection, stick with your doctor's prescribed antibiotic treatment [Data not available].
