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.

Primary outcome measure(s)
Time to recurrence of clinically suspected UTI — 6 months Time (days) to recurrence of clinically suspected UTI
Symptom Severity as Measured by the Urinary Tract Infection Symptom Assessment Questionnaire (UTI-SIQ-8) — 6 months Change from baseline to 6 months in total score on the Urinary Tract Infection Symptom and Impairment Questionnaire (UTI-SIQ-8). The UTI-SIQ-8 consists of 8 items scored from 1 to 5. Total scores range from 8 to 40, with higher scores indicating worse urinary tract infection symptom severity and impairment.
Ratio of Good to Bad Urinary Health Days — 6 months Ratio of self-reported "good urinary health days" to "bad urinary health days" recorded in daily electronic diaries over 6 months. A higher ratio indicates a greater proportion of good urinary health days relative to bad urinary health days.
Patient Global Impression of Change (PGIC) — 6 months Patient-reported global impression of change at 6 months as measured by the Patient Global Impression of Change (PGIC). The PGIC is a 7-point ordinal scale ranging from 1 (Very much improved) to 7 (Very much worse). Higher scores indicate worse perceived change.
Quality of Life as Measured by the Modified Recurrent Urinary Tract Infection Impact Questionnaire (m-RUTIIQ) — 6 months Change from baseline to 6 months in total score on the Modified Recurrent Urinary Tract Infection Impact Questionnaire (m-RUTIIQ). Total scores range from 0 to 100, with higher scores indicating greater negative impact of recurrent urinary tract infections on quality of life.
Symptom Severity as Measured by the Recurrent Urinary Tract Infection Symptom Scale (RUTISS), Section C — 6 months Change from baseline to 6 months in Section C score of the Recurrent Urinary Tract Infection Symptom Scale (RUTISS). Section C items are scored on an 11-point numeric rating scale (0-10) and transformed to a total score ranging from 0 to 100. Higher scores indicate greater urinary tract infection symptom severity.
