Is the problem only with the caffeine? What else might be dangerous in these drinks?
But if you are a Starbucks fan, a 16-ounce serving (Grande) of their regular brewed coffee ( not espresso-based) there can average 330 milligrams of caffeine but range from 259 to a whopping 564! These are Starbucks' own reported values, levels that led to list this product's caffeine content as "Extreme."īut think about this: that high end for the "Extreme" content of Starbucks is roughly the same as only two small bottles of 5-hour Energy, perhaps telling us how deceivingly potent these "shots" can be. There you'll see that a large McDonald's coffee (16-ounce) has 145 milligrams of caffeine, just a bit less than the same as in a typical regular Rockstar or Monster product. One of the most comprehensive sources for caffeine content of beverages is this database at. Well, it depends on where you get your coffee. bottle (the "extra strength" only contains a bit more at 242 milligrams.). The more concentrated 5-hour Energy doesn't list its caffeine content but Consumer Reports recently determined that it contains 215 milligrams of caffeine per 2 fl. That's about three-to-five times the amount of caffeine in 12-ounce serving of a typical mass-marketed soda. Monster and Rockstar are brightly-labeled beverages that contain 160 to 175 milligrams of caffeine in drink sizes ranging from 5 to 16 fluid ounces. Rockstar was listed in 13 cases, none of which were deaths.
Monster drinks were listed in five deaths and about 35 other non-fatal adverse reactions. The non-fatal reports extend back to 2005 and include typical symptoms such as dizziness, anxiety, and nausea all the way to seizures, brain hemorrhages, and heart attacks.
