Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Lactobacillus is a genus of probiotic bacteria that has been investigated for its potential to alleviate symptoms of Irritable Bowel Syndrome (IBS). Scientific interest in Lactobacillus stems from its role in maintaining gut microbiota balance, enhancing the intestinal barrier, and modulating immune responses. Several randomized controlled trials (RCTs) and meta-analyses have assessed the efficacy of various Lactobacillus strains (e.g., L. plantarum, L. acidophilus, L. rhamnosus) for IBS symptom relief.

Overall, the evidence suggests that certain strains of Lactobacillus can provide modest improvement in overall IBS symptoms, particularly bloating and abdominal pain. For example, meta-analyses published in reputable journals such as Alimentary Pharmacology & Therapeutics and Gut have found that probiotics, including Lactobacillus species, may reduce global IBS symptoms compared to placebo. However, the heterogeneity of study designs, strains used, dosages, and outcome measures makes it difficult to draw definitive conclusions. Not all Lactobacillus strains are effective, and benefits appear to be strain-specific.

Current clinical guidelines, such as those from the American College of Gastroenterology (ACG), recognize probiotics (including some Lactobacillus strains) as a potential adjunct for symptom management in IBS, but they emphasize the limited and inconsistent quality of evidence. Thus, while there is scientific validation for the use of certain Lactobacillus strains in IBS, the strength of evidence is moderate, justifying a rating of 3 on the evidence scale.
