Energy drinks are highly caffeinated beverages designed to provide a short-term energy boost.
These drinks typically contain as much caffeine as a cup of coffee and three times as much as a standard soft drink, with some brands containing much higher doses. Energy drinks also contain sweeteners, amino acids such as taurine or l-carnitine, massive doses of B vitamins, and plant or herbal extracts such as gingko biloba, ginseng, or milk thistle. The potential interactions among these ingredients are not well understood.
With sales expected to approach $20 billion a year by 2013 in the U.S. alone, energy drinks such as Red Bull, Monster, and Rockstar have become staples of the adolescent and young adult market. Although provocatively named brands such as Full Throttle, Daredevil, Havoc, Rage, Bawls, Who’s Your Daddy, Whoop Ass, and Extreme Ripped Force are designed to appeal to a target demographic of 18-25 year olds, they are nearly as common among high school students.
Excessive energy drink use is associated with several potential health risks. Overuse can lead to symptoms ranging from mild (headaches, jitteriness, anxiety) to severe (insomnia, heart palpitations, seizures). Poison control centers and emergency rooms have documented a rapidly growing number of cases of caffeine intoxication involving energy drink use, particularly when coupled with alcohol or other substance use. After several highly publicized cases in 2010, the FDA no longer permits ready-to-drink alcoholic beverages such as Four Loko, Joose, or Maxx to contain caffeine. However, caffeinated mixed drinks such as Red Bull & vodka or Jagerbombs remain extremely popular.

ATHLETES: Energy drinks before or during games or practices? Probably not a good idea. Though often confused, energy drinks are not sports drinks. Where Gatorade or Powerade are designed to provide hydration and replace electrolytes, caffeine actually contributes to dehydration. Adults and especially children may experience headaches, heart palpitations, hypertension, or blackouts if they combine energy drinks with heavy exercise.
CAFFEINATED COCKTAILS: Combining alcohol (a depressant) with caffeine (a stimulant) may make drinkers look, sound, and feel less drunk than they actually are. Underestimating one’s own intoxication puts you at greater risk for drunk driving, alcohol poisoning, and even sexual victimization. Mixing caffeine and alcohol may also lead to heavier drinking than alcohol alone for three reasons: (1) caffeine postpones the sleepiness associated with intoxication, so you can drink longer; (2) energy drink flavors mask the taste of alcohol, so drinks taste better; and (3) caffeine has a “priming” effect on alcohol—that is, it strengthens cravings for another drink.
CAFFEINE: Many consumers of energy drinks and other caffeinated beverages forget that caffeine is a psychoactive stimulant drug, and like other drugs, it is highly addictive. Just like alcohol, if you’re going to drink energy drinks, do it responsibly! Unlike soft drinks, there are no official limits on how much caffeine an energy drink may contain. Read the label, and if it doesn't specify the exact caffeine content (many don’t), go on-line and find out. Knowledge is power.
MYSTERY INGREDIENTS: Energy drinks typically contain a brand-specific proprietary blend of plant and herbal extracts. Most of these ingredients (such as gingko biloba or ginseng) are probably harmless. Others may not be. For example, the bitter orange found in some brands is closely related to ephedra, a compound banned by the FDA in 2004 due to a number of consumer deaths. Because energy drinks are classified as dietary supplements, their content is not subject to direct regulation or oversight by the FDA. It’s up to the user to investigate the label. Buyer beware-- Know what you’re drinking!
