Abstract
Comprehensive review of probiotic health benefits including effects on gut microbiome, immune function, and metabolic health.
Methodology
Narrative review of probiotic mechanisms and clinical applications across gastrointestinal, immune and metabolic outcomes.
Key Findings
Reviewed evidence supports probiotics for antibiotic-associated and infectious diarrhoea, some benefit in irritable bowel syndrome symptoms, and modulation of mucosal immunity through competitive exclusion of pathogens, barrier reinforcement and cytokine modulation. Effects are strain-specific and dose-dependent; benefits shown for one strain cannot be assumed for others.
Conclusions
Probiotics are generally safe in healthy people and have credible benefit for specific diarrhoeal and gut conditions, but claims must be made at the strain level rather than for probiotics as a category.
Limitations
Narrative review without systematic search or pooled estimates; wide heterogeneity in strains, doses and endpoints; safety caution warranted in immunocompromised and critically ill patients.
Supplements Studied

Effects are strain-specific and dose-dependent; benefits shown for one strain cannot be assumed for others.
