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.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Cranberry phospholipids
What this could lead to
If it works, this could point toward a natural supplement to ease frequent urination in healthy adults.
What could go wrong
This is a small, early-stage trial with only 76 participants. The effect may be small or no better than placebo, and results may not apply to other groups.
