Methods: This is across sectional study was conducted among 395 of the students of Northern Border University, KSA. Respondents were interviewed and filled a predesigned questionnaire. Results: The percentage of pupils that use caffeine was determined to be 92.2% in our survey. Caffeine use had no significant relationship with sex, age, BMI, study level, or GPA (P> 0.05). Coffee was the most prevalent source (89.3%), followed by chocolate (54.4%). In terms of daily caffeine use, 29.9% consume it three times a day, 28.6% two times a day, 13.7% four times a day, and 17.0% three times a day. When it comes to the rationale for daily intake, 40.9% use caffeine to improve attention, 29.7% use it to stay awake during courses, and 28.6% use it for morning vigour.When it comes to the time of day when people consume the most caffeine, 40.1% consume it in the late evening, which accounts for more than half of all cases. 61.3% believed that caffeine improves his or her GPA, and 59.9% agreed that caffeine extends study time. The majority (60.4%) believe that caffeine reduces body weight, while 44% have experienced negative side effects as a result of caffeine usage. 16.8% of people suffered tachycardia, while 14% felt gastrointestinal discomfort. Conclusion: Almost all studied students of NBU consume caffeine products. The most common source was coffee. Most of the students agreed that caffeine increases study hours and increases his/her GPA.
