The Most Caffeinated Drinks

Coffee and tea are classic and natural sources of caffeine for a little pick-me-up, but if you’re in need of a bigger dose, more along the lines of a venti quad-shot latte at Starbucks (Stock Quote: SBUX), there are several drinks to choose from that come cheaper, and in much smaller packages. While we don’t condone over-the-top caffeine use, we are big proponents of smart spending, so here’s a look at 20 drinks with the highest caffeine content per ounce, according to energyfiend.com, that are likely to give you the most bang for your buck.

Two to four cups of coffee at day, or about 200 to 300 milligrams of caffeine should be fine for most people, according to the Mayo Clinic. But as many caffeine consumers know, these jolting drinks can leave you irritable, shaky, nervous and restless. Even worse, caffeine can make your heart beat at dangerously high rates and cause gastrointestinal problems. Extreme amounts of caffeine can even kill you. But if you can control your caffeine consumption and limit it to safe levels, here are a few small bottles that pack a potent punch. Photo Credit: 5150juice.com
