Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Leuconostoc is a genus of lactic acid bacteria commonly found in fermented foods and sometimes included in probiotic formulations. Its use in supporting or treating Irritable Bowel Syndrome (IBS) is grounded in scientific exploration, though the evidence is limited and not robust. Clinical studies investigating probiotics for IBS have primarily focused on genera like Lactobacillus and Bifidobacterium. However, some multi-strain probiotic products that include Leuconostoc species (such as Leuconostoc mesenteroides) have been tested in small-scale studies and have shown modest benefits in improving IBS symptoms, likely due to their ability to modulate gut microbiota, produce short-chain fatty acids, and inhibit pathogenic bacteria. A few clinical trials and reviews (e.g., in Beneficial Microbes and World Journal of Gastroenterology) mention Leuconostoc as a minor component in multi-strain probiotics with some reported symptom relief, but they do not attribute specific effects to this genus alone. Overall, while Leuconostoc is present in some probiotic interventions for IBS, direct high-quality evidence for its efficacy as a primary or standalone treatment is lacking. Its use is thus scientifically motivated but evidence remains preliminary and indirect, justifying a low-to-moderate rating.
