Summary and Appraisal of Key Evidence
Study 1 Howell, (2010) completed a multi-location randomized, double-blind versus
placebo study to evaluate whether cranberry powder can be utilized in the prevention of UTIs by
inhibiting bacterial adhesion and virulence in the urinary tract, providing Level 1, Grade A level
of evidence. Study participants included-32 women from Japan, Spain, France, and Hungary.
The women were sexually active, over the age of 18, and demonstrated normal renal function.
Participants were excluded if they had been on antibiotic therapy in the last 6 months, had an
allergy or intolerance to cranberry products, were pregnant, or routinely consumed food
supplements which had vitamins, minerals or trace elements. The study did not include the ages
of the women, and it cannot be assumed that the elderly population is represented in this study.
