This research aimed to investigate the perception and intake patterns of caffeinated beverages. Self-administered questionnaires were distributed to 394 adults in their twenties and thirties. The survey covered general information, awareness of caffeine, and the consumption patterns of caffeinated beverages. The primary factor influencing caffeine purchases was taste (75.3%), followed by price (10.7%) and health/nutrition considerations (10.2%). The reasons for caffeine intake included fatigue recovery (34.3%), improved concentration (22.1%), and taste preference (18.5%). Among the participants, 62.2% reported experiencing side effects from caffeinated beverages, including symptoms such as insomnia (21.6%), palpitations (18.0%), and frequent urination (11.4%). Remarkably, 90.6% of the participants were either unaware of or possessed incorrect information about the recommended daily caffeine intake. The average daily caffeine consumption for all participants was 104.66 mg, with men (113.34 mg) having a higher intake than women (97.79 mg). Most of the caffeine intake was from coffee at 85.6%, followed by carbonated beverages (6.4%), processed milk (3.5%), and tea (2.9%). These results highlight the critical need to disseminate accurate information to enhance public knowledge about caffeine.
