Whether or not caffeine is good for you remains a mystery. Amazingly, an estimated 21,000 studies have been conducted to finally put an end to this debate. But, so far, nothing has been determined with any degree of certainty. So, we’ll instead focus on the one thing we know for sure: excessive amounts of caffeine—like the ones in the list below—can make you feel, shall we say, amped up.
1. Nestea Cool Ice Tea
A Nestea bottle the same size as that of the Diet Coke is actually one of the lesser offenders on this list. At just under 1 milligram per ounce of caffeine, a 20-ounce bottle contains about 20 milligrams of caffeine in it. Be advised and aware of the high sugar content in bottled ice teas. Perhaps reaching for a diet version of the drink is the way to go.
2. SoBe Adrenaline Rush
They don’t call this Adrenaline Rush for nothing! Don’t let this skinny little can fool you—even at a mere 8.3 ounces, this energy drink has 79 milligrams of caffeine in it. Making matters worse, because the can is smaller than a typical soda can, people sometimes feel the need to drink two of them at a time. 79 + 79 = 158 milligrams. Not good.
3. Mountain Dew
A 12-ounce can of this known high-sugar, high-caffeine soda has almost the same amount of caffeine in it as the aforementioned 20-ounce bottle of Diet Coke. What if the Mountain Dew was in the 20-ounce bottle? Well, you’d be gulping down close to 118 milligrams of leaded fuel.
4. Diet Coke
66 milligrams of caffeine are packed into a 20-ounce bottle of this sugar-free soft drink. If you need a visual on how big a 20-ounce bottle is, know that it is the is the same size as a bottled water.
