UTI Prevention

Reviewed by the Nimbera editorial team · Last updated May 2026

Urinary tract infections are bacterial infections (most commonly E. coli) affecting the bladder and urethra. These remedies are for prevention of recurrence in people with a history of UTIs - they are not treatments for an active infection.

When to see a doctor

See a doctor immediately for any suspected active UTI (burning urination, frequent urge, cloudy or bloody urine, fever, or back pain). These remedies are not a substitute for antibiotic treatment of an existing infection. Also see a doctor if you have more than 3 UTIs per year.

Cranberry (Proanthocyanidins)

ingestible
Fu et al. (2017, PMID 29046404) meta-analysis of 7 RCTs (n=1,498) found cranberry reduced UTI recurrence risk by 26% (pooled RR 0.74; 95% CI 0.55-0.98) in otherwise healthy women. Active component is type-A proanthocyanidins (PACs); juice and capsule forms both studied.

D-Mannose

ingestible
Kranjcec et al. (2014, PMID 23633128) 3-arm RCT (n=308 women) found D-mannose 2 g/day for 6 months reduced UTI recurrence to 14.6% vs 60.8% in no-prophylaxis controls. Recurrence was comparable to nitrofurantoin (20.4%) but with significantly fewer side effects. Note: a 2024 JAMA Internal Medicine RCT (PMID 38587819) found no significant benefit in a broader population.

Lactobacillus Probiotics

ingestible
Beerepoot and Geerlings (2016, PMID 27092529) review found intravaginal Lactobacillus crispatus in premenopausal women and oral L. rhamnosus GR-1 + L. reuteri RC-14 in postmenopausal women are promising for UTI prevention, though overall RCT results remain inconclusive due to small sample sizes and inconsistent dosing strategies.
$25-$45 per month

Increased Water Intake

lifestyle
Hooton et al. (2018, PMID 30285042) RCT (n=140 premenopausal women with recurrent UTI and low baseline fluid intake) found adding 1.5 L water/day reduced mean annual cystitis episodes from 3.2 to 1.7 and extended infection-free interval from 84 to 143 days.
