Study on Caffeinated Beverages and Well-being

This study is looking at how different caffeinated beverages affect your well-being. Researchers want to understand how variations in sweetener and caffeine content in drinks like the "Caffeinated, low sugar beverage," "Caffeinated beverage," and "Control beverage" impact people. You might be able to join if you are between 18 and 55 years old, generally healthy, and regularly drink sweetened caffeinated beverages. The main goal is to see how you feel after drinking these beverages, measured by subjective caffeine visual analog scales (a way to rate your feelings) on Day 5. The current status of this study is unclear.

Study design
This interventional study plans to enroll 75 participants to evaluate responses to different caffeinated beverages.
What's involved
You would need to substitute your current caffeine routine for the test beverage daily. Subjective caffeine responses will be measured on Day 5.
Compensation
Not stated in the trial record.
Follow-up
Subjective caffeine visual analog scales are measured at Day 5, indicating follow-up for at least this duration.
