According to a new study by Michigan State University, energy drinks can have up to FIFTEEN TIMES the amount of caffeine of a can of Coke.
A can of Coke has 34 milligrams of caffeine. A can of an energy drink… from Red Bull to Rockstar to Amp…has between 80 and 500 milligrams.
For reference, the average cup of coffee has between 90-150 milligrams of caffeine. A Venti at Starbucks… meaning the really big one… has 480 milligrams of caffeine… the same as the most caffeinated energy drinks.
