Abstract: Caffeine is a widely consumed stimulating agent. Health authorities recommends daily intake below 3 mg/kg body weight. The study assessed caffeine content in different Egyptian caffeinated products and estimated the mean daily intake among Alexandria University Employees. Different caffeine containing products were analyzed using HPLC also a cross sectional study was conducted on randomly selected 500 Alexandria University Employees of both sexes to collect data about their frequency consumption using FFQ. Instant coffee black had the highest content of caffeine (0.891±0.094 mg/g). Daily caffeine Intake was more than the recommended level among 36.6% of studied sample while 61.4% consumed at least one caffeinated beverage per day. Mean daily caffeine intake was 254.58±230.78 mg. Caffeine intake among higher consumers was double the safe level which recommended by EFSA (190.86±100.35%). Tea followed by instant coffee black and cola beverages were the key contributors to daily caffeine intake.
