The Buzz on Energy Drinks

Font Size: Reset

Sometimes coffee won't cut it. Sometimes you need something stronger, something with kick: caffeine, taurine, L-carnitine, ginseng and -- horny goat weed?

To test the effects, taste and consequences of energy drinks, my editor suggested I take a random sampling of a few of these potent potions. So, in a rare occurrence, he suggested I take $20 from petty cash and see what I could get.

I was excited about free anything, plus the chance to test the limits of human caffeine consumption. However, it would not be the nonstop party I anticipated.

Since more than 500 energy drinks were released last year alone, I had quite a few options. It's a nearly $3.5 billion-a-year industry, according to Beverage Digest. The drinks are primarily marketed toward teens and men in their 20s. That's not surprising when you consider the edgy names -- Monster, Full Throttle, Adrenaline, Red Bull and Cocaine.

I bought 10 different types of drinks, ranging in price from 99 cents to $2.50, some even being hybrids of malt-liquor and caffeine -- but more on that later. Since most of the larger cans (energy drinks come in two basic sizes: 8.4 and 16 ounces) recommend not exceeding three cans in a day, I decided to stretch the experiment over three fun-filled, sugar-buzzed, extra-edgy days.
