The following is being released by the American Beverage Association:
Contrary to what you might have heard, the vast majority of energy drinks consumed in the U.S. – including Monster, Red Bull, Rockstar, AMP, Full Throttle and NOS – have similar or lower levels of caffeine than home-brewed coffee which many Americans enjoy on a daily basis. And many contain about half the caffeine of a similarly-sized coffeehouse coffee.
Check out the caffeine comparison chart.
A 16 fluid ounce energy drink typically contains between 160 and 240 milligrams of caffeine, while the same size coffeehouse coffee contains around 300 to 330 milligrams. Moreover, caffeine has been safely consumed around the world for hundreds of years.
