Caffeine is a natural stimulant found in coffee, tea, and chocolate and a common additive to some drinks and powders.

Males and females had similar intakes of caffeine for each age group. Both males and females over 30 years consumed more caffeine than younger age groups on average, with daily median intakes of over 150 mg and daily mean intakes of over 170 mg for age groups 31-50 and 51-70 years. This is the equivalent of over four cups of black tea, or one and a half espresso shots of coffee. Approximately one quarter of 51-70 year olds consumed the equivalent of six to seven cups of tea or two to three espresso shots of coffee each day (75th percentile of caffeine intakes of 259 mg for males and 238 mg for females aged 51-70 years).
