Cranberry & Recurrent UTIs
Recently The American Journal of Clinical Nutrition, reported on the efficacy of supplementing with whole cranberry fruit powder for women with recurrent urinary tract infections (UTIs). 150 women with a history of recurrent UTIs, defined as ≥ 3 UTIs in the last year or ≥ 2 UTIs in the last 6 months (but excluding women with > 5 within 6 months), received one daily capsule of either placebo or 500 mg whole cranberry powder. Urine cultures were performed at baseline, 3 months, 6 months, and any time a woman presented with symptoms of a UTI.
At 6 months, the whole cranberry extract reduced culture-confirmed UTIs by 52% compared to placebo. Additionally, E. coli was the most frequently detected uropathogenic species in UTIs, and its incidence was also reduced by 51% among women taking cranberry extract. UTIs with symptoms of frequency and urgency were reduced by 71%, with a 59% reduction in the mean total number of UTIs per participant. There was no difference between groups regarding safety outcomes, with no serious adverse events reported.
We use Cranberry Complex which is a combination of cranberry and other herbs which support the urinary tract. Most of our patients have commented that the discomfort from a UTI is greatly or completely relieved within 30-60 minutes from taking this supplement, often with Golden Seal from MediHerb. It is prudent to take the combo - generally 2-3 tablets of each 2x/day for 10 days. Repeat urinalysis confirms that most women and men have complete resolution of a UTI without the use of antibiotics that often cause a secondary yeast infection.
