A Single-Arm Exploratory Study of NatureU Pelvic Health Pumpkin Seed in Women With Urinary Frequency and Leakage Symptoms

The study was designed as an exploratory self-controlled human evaluation of an oral functional food product containing pumpkin seed extract and soybean extract. Eligible female participants aged 35 to 55 years with urinary frequency and urinary leakage symptoms received the study product after investigator review of the inclusion and exclusion criteria. Participants received the product at the study center on Day 0 and took the product continuously for 7 days through Day 7. The report tables compare questionnaire scores at Day 0 and Day 8. Enrollment was completed on July 15, 2024, product intake was completed on July 21, 2024, and evaluation information collection was completed on July 22, 2024. The study was open-label, single-center, and exploratory, with no placebo or parallel control group. Within-participant changes from baseline were analyzed using paired t tests. Safety monitoring included adverse reactions and changes in blood pressure, fasting blood glucose, and waist circumference.
