It’s about twice that in Scandinavia and South America. Yet women in the US would need to drink two to three times this average to lower their risk of basal cell skin cancer by 20%.
Of the beverages on the list, brewed coffee provides the greatest amount of caffeine, but a 5-hour energy drink provides a bit more. Espresso is lower in caffeine, but packs in more than brewed tea.

Warwick says different people experience the jitters differently than others. Also, we might add that the body adjusts to the caffeine from regular coffee drinking and the body may need increased amounts to reach the jittery stage after awhile.
