Effects of the Consumption of Test Product on Urination in Healthy Japanese Adults: A Randomized, Placebo-Controlled, Double-Blind, Parallel-Group Comparison Trial

Обзор

The goal of this clinical trial is to test in Japanese adults who experience concerns regarding urinary frequency. The main question it aims to answer is: •Does consumption of Cranberry Phospholipids reduce daytime urinary frequency? Participants will be given the following tasks: * Take two tablets daily containing Cranberry Phospholipid for eight weeks. * Answer the questionnaire on the overactive bladder (OAB)-specific quality of life (QOL). * Answer the questionnaire on OAB symptoms. * Answer the questionnaire on urinary frequency during the study period. Researchers will compare Cranberry Phospholipids and placebo groups to see if Cranberry Phospholipids reduces daytime urinary frequency.
