2Systematische Übersichtn=8,857 · very large study2023
These data support the use of cranberry products to reduce the risk of symptomatic, culture-verified UTIs in women with recurrent UTIs, in children, and in people susceptible to UTIs following interventions.
Williams G et al. · Cochrane Database of Systematic Reviews (2023)
Fifth update of the Cochrane review; 50 included studies with 8857 randomised participants.
Cranberry products reduce the risk of symptomatic, culture-verified UTIs in women with recurrent UTIs.
Benefit also seen in children and in people susceptible to UTIs following interventions.
3UTI incidence in susceptible populationsMeta-Analysen=3,979 · very large study2021
We found that cranberry-based products intake can significantly reduce the incidence of UTIs in susceptible populations (risk ratio (RR) = 0.70; 95% confidence interval(CI): 0.59 ~ 0.83; P<0.01).

Meta-analysis of 23 trials with 3979 participants.
Cranberry intake significantly reduced UTI incidence in susceptible populations (RR = 0.70; 95% CI: 0.59-0.83; P<0.01).
Risk reduction of 32% in women with recurrent UTIs, 45% in children, and 51% in patients using indwelling catheters.
18Symptomatic UTI recurrenceRCTn=145 · medium study2021
Post-hoc results reveal that this high dose of proanthocyanidins may have a preventive impact on symptomatic urinary tract infection recurrence in women who experienced less than 5 infections per year.

Randomized, double-blind RCT in 145 healthy women with recurrent UTI over 24 weeks.
High dose (2 x 18.5 mg PACs/day) vs low dose (2 x 1 mg PACs/day).
Non-significant 24% decrease in symptomatic UTIs between groups (incidence rate ratio 0.76, 95% CI 0.51-1.11).
Larger, multicentre randomised controlled trials are required to establish optimal dosing, long-term safety, and therapeutic potential.

Nanocurcumin consistently improved EDSS in relapsing-remitting MS (3 trials, n = 150; p = 0.039-0.041), while epigallocatechin-3-gallate, silymarin (SM), cranberry extract, and bio-enhanced curcumin extract (BCM-95) curcumin showed no significant impact on disability, relapse rates, or MRI outcomes.
Meta-analysis was not possible due to the heterogeneity of included studies.
Conclusions : Nanocurcumin may contribute to improvements in disability outcomes in Relapse Remitting Multiple Sclerosis (RRMS), whereas other polyphenols lack consistent efficacy.
