Introduction and purpose: The gut microbiota plays a vital role in modulating health, immunity, and recovery, all of which are crucial for athletes. Limosilactobacillus reuteri DSM 17938 is a well-documented probiotic strain with anti-inflammatory, immunomodulatory, and gastrointestinal benefits. This review explores its potential application in supporting athletic performance and post-exercise recovery.
Material and method: A narrative literature review was conducted using PubMed, Scopus, and Google Scholar databases. Articles published between 2000 and 2024 were included, with a focus on clinical and experimental studies evaluating the effects of L. reuteri DSM 17938 on gastrointestinal function, inflammation, immune response, and athletic outcomes.
Results: Evidence suggests that L. reuteri DSM 17938 contributes to gut barrier integrity, reduces exercise-related gastrointestinal discomfort, modulates inflammatory cytokines (e.g., IL-6, TNF-α), and supports immune function. While direct evidence linking this strain to improvements in performance metrics (e.g., endurance, VO₂max) is limited, its supportive role in recovery and resilience is promising.
Conclusions: L. reuteri DSM 17938 shows potential as a functional supplement for athletes, particularly in improving gut health, reducing inflammation, and enhancing immune defense. Further clinical research is needed to confirm its direct effects on athletic performance
