Summary

This study looks at whether a fermented papaya supplement can help older adults (ages 70-80) make fewer mistakes while driving. Participants take three doses of the supplement in one day and then complete a driving simulator test. The goal is to see if the supplement improves attention, memory, and reaction time behind the wheel.
