Overview
This is a 6-month, three-arm randomized controlled trial evaluating the efficacy and safety of a dietary supplement drink mix on urinary health outcomes in adult females. Participants will be randomly assigned to one of three study arms and followed for six months to assess changes in urinary health measures.
Description
Urinary tract infections (UTIs) are extremely common, affecting up to 60% of women in their lifetime, with 20-40% experiencing recurrent infections. Recurrent UTIs-defined as two infections in six months or three in one year-create a significant burden on quality of life and healthcare costs. Antibiotics are the standard treatment, but repeated use can contribute to antibiotic resistance, incomplete bacterial clearance, and disruption of the microbiome.
Non-antibiotic approaches, such as D-mannose, vitamins, and hydration support, have shown potential to help reduce UTI recurrence. D-mannose may prevent E. coli-the most common UTI-causing bacteria-from adhering to the urinary tract, while vitamins and electrolytes may support hydration, urinary pH, and immune function.
This clinical trial will evaluate the efficacy of a dietary supplement drink mix containing D-mannose, vitamins, and electrolytes in improving urinary health outcomes over a 6-month period in adult females. The goal is to determine whether this non-antibiotic approach can support urinary health and help reduce factors associated with recurrent UTIs.
