Cranberry pills tested for bathroom breaks
NCT ID NCT07393126
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a daily cranberry phospholipid supplement can reduce how often healthy Japanese adults need to urinate during the day. Over eight weeks, 76 participants will take either the supplement or a placebo and answer questionnaires about their bladder symptoms and quality of life. The goal is to see if the supplement eases urinary frequency without medical treatment.
