ClinConnect Summary

This clinical trial is looking into whether drinking cranberry juice for 70 days can help improve how well people think and perform tasks, especially when they are juggling multiple things at once. The study focuses on healthy men and women aged 30 to 55 who experience stress from multitasking. Researchers believe that cranberry juice, which is rich in beneficial compounds, may help reduce mental stress, improve focus, and even enhance memory. The trial will involve participants consuming either cranberry juice or a placebo (a drink that looks like cranberry juice but has no active ingredients) without knowing which one they are drinking.

To participate, individuals must weigh at least 110 pounds, be between 30 and 55 years old, and have a body mass index (BMI) within a certain range. However, those with certain health issues, high caffeine or alcohol intake, or other specific conditions will not be eligible. Participants can expect to undergo assessments of their cognitive abilities and stress levels during the study, and they'll also need to follow some dietary guidelines. This research might provide valuable insights into how cranberry juice could help people manage stress and improve their thinking skills in daily life.
