What probiotics are best for preventing UTIs?
Probiotics containing Lactobacillus strains, especially Lactobacillus rhamnosus and Lactobacillus reuteri, have shown the most evidence for helping to prevent recurrent urinary tract infections in women.
Detailed Medical Explanation
Multiple clinical studies support the use of vaginal and oral probiotics with Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 for reducing UTI recurrence. These beneficial bacteria help restore the natural vaginal flora and may inhibit pathogenic bacteria. While promising, probiotics are an adjunct to—not a substitute for—medical treatment.

Clinical Context
Clinics sometimes recommend specific probiotic strains for women with recurrent UTIs. Discuss the best options with your clinician before starting supplements.
Evidence-Based Approaches
NICE and NHS recommend probiotics only as part of a comprehensive prevention plan, especially for women with repeated infections.
