If you have been struggling with getting back into the groove since returning from Christmas break, Dunkin' just might have a solution. Instead of ordering a regular coffee, try out what Dunkin' is calling its "Extra Charged" coffee.

Dunkin' says its "Extra Charged" coffees have 20 percent more caffeine than its normal hot or iced coffees. The additional caffeine comes from green coffee extract, meaning the caffeine is extracted from the coffee bean itself before it goes through the roasting process.

Bragging about extra caffeine boosts is nothing new in the beverage world.

Mountain Dew wasn't specifically marketed with the "we have high caffeine" message, but everyone knew what they were getting into when they cracked one open. Pepsi eventually did get into the caffeine race when it released Mountain Dew Kickstart – you know, just in case a regular Mountain Dew wouldn't do the trick.

Kids from the '80s might remember Jolt Cola. Jolt's slogan unapologetically boasted "All the sugar and twice the caffeine." Take THAT, Mom! In reality, it was the world's first energy drink.

Red Bull came out in the '90s, followed a few years later by Monster energy drinks. These caffeine-rich beverages were trailblazing in the energy drink industry.

If you are looking for something a little more direct, 5-Hour Energy concentrates your standard energy drink into the form of a shot. Amounts vary between the different selections, but you can expect to see somewhere between 200 and 250 mg of caffeine in a shot of 5-Hour Energy.

Adding a shot of espresso into your Dunkin' is also an option for some coffee lovers, but Dunkin' says its new Extra Charged coffee allows customers to get more caffeine without changing the taste of their favorite coffee.
