Rating (out of 5): 3

Lactobacillus species, particularly Lactobacillus rhamnosus and Lactobacillus reuteri, have been studied for their role in supporting urinary tract health, with a primary focus on preventing recurrent urinary tract infections (UTIs). The rationale is based on their ability to colonize the vaginal and periurethral region, thereby providing a protective barrier against uropathogens such as Escherichia coli. Several randomized controlled trials and meta-analyses (notably in women with recurrent UTIs) have shown that certain probiotic strains can reduce UTI recurrence, though results are mixed and efficacy appears to depend on the strain, dosage, and delivery method (oral vs. vaginal). The proposed mechanisms include production of bacteriocins, lowering of pH through lactic acid production, and competitive exclusion of pathogens. However, while promising, the clinical evidence is not uniformly strong across all Lactobacillus strains, and guidelines do not universally recommend their use as a primary preventive measure. Nevertheless, scientific literature supports a moderate benefit, particularly as an adjunct to conventional therapy or for individuals seeking alternatives to antibiotics. The evidence for general urinary system "support" beyond UTI prevention is less robust. Overall, use of Lactobacillus for urinary tract health is partially validated by scientific studies, meriting a mid-range evidence rating.
