Are Energy Drinks Safe?

What Is In Energy Drinks?Precise recipes vary, but the common element is caffeine. Caffeine is the key ingredient in energy drinks.A standard cup of coffee has about 100 mg of caffeine, a cup of tea 50 mg and a can of cola 35-55 mg. Energy drinks usually have more. A single serving of an energy drink can have anywhere from 50 to 500 mg of caffeine. And the addition of guarana (a South American plant extract that contains additional caffeine) ups the caffeine dose even more. Although the FDA regulates the amount of caffeine in soft drinks (maximum of 71 mg per 12–oz serving), there is no such limit for energy drinks.Caffeine is a stimulant. Scientific studies in adults show that caffeine can increase alertness, improve concentration and enhance mood. Modest caffeine intake (less than 400 mg per day) is safe for most adults. But too much caffeine can cause problems, including restlessness, irritability and difficulty sleeping. Massive caffeine overdoses can cause reduced blood flow to the heart and abnormal heart rhythms.Many energy drinks also contain sugar. Sugar is “real energy.” Your body can use the sugar as fuel to do work. But don’t forget that extra sugar means excess calories. A steady consumption of sugar-filled energy drinks will lead to weight gain.Other ingredients, including the amino acid taurine, ginseng and assorted vitamins, probably have little to no impact on a person’s perceived energy level. Although manufacturers tout the importance of these additives, their purported benefits are unproven.  One note of caution—ginseng can interact with a variety of prescription medicines.RECIPE: Healthy AND Tasty Recipes to Boost EnergyEnergy Drinks vs. Sports Drinks: Know the DifferenceAlthough often displayed in the same section of the store or even right next to each other, energy drinks (e.g. Monster, Five Hour Energy) and sports drinks (e.g. Gatorade, Powerade) are not interchangeable. Containing water, carbohydrates and electrolytes, sports drinks help athletes to rehydrate and replenish electrolytes and carbohydrates lost during strenuous athletic activity; this is a perfectly legitimate use of these products.Energy drinks are different. Containing stimulants, they do not replenish electrolytes. Furthermore, caffeine can be dangerous for the dehydrated athlete who already has an elevated heart rate and blood pressure from physical exertion. Do not use energy drinks during sports—they do not provide the “energy” you need.Energy Drinks Are Not for KidsMore than half of the energy drink market consists of children and young adults. Although endorsed by sports stars and targeted to younger people, energy drinks are not for kids. The American Academy of Pediatrics summed it up, concluding that “energy drinks have no place in the diet of children and adolescents.”MORE: The Downfall of Drinking Your CaloriesEnergy Drinks and Alcohol: Danger!On November 17, 2010, the FDA ruled that premixed drinks that include both alcohol and caffeine (alcoholic energy drinks) are unsafe. Although this stopped sales of such beverages, the ruling did not curtail the practice of combining alcohol with energy drinks. People just mix the drinks themselves. Surveys find that 25 to 50 percent of college students regularly consume combinations of energy drinks and alcohol. This is a dangerous practice.The caffeine in energy drinks can counteract the drowsiness normally caused by alcohol. Drinkers stay awake longer and often drink more. This increases the risk of alcohol poisoning.In addition, the energy drink can create the perception that the drinker is not impaired by the alcohol; the drinker feels more “alert” and believes that his reflexes (and driving ability) remain intact. This can lead to serious problems behind the wheel. Energy drinks do not counteract alcohol’s effect on dulling reflexes.If you are of age, drink alcohol responsibly. Don’t mix alcohol and driving. And don’t mix alcohol and energy drinks.MORE: Drinks That Reduce AppetiteAre Energy Drinks for You?In a court of law, we presume that a person is innocent until proven guilty. When it comes to medicine, we take the opposite approach. A drug or supplement is considered dangerous until proven safe.Energy drinks have not been proven safe. In fact, because they are classified as supplements, they are not even regulated by the FDA. This means that their ingredients are not tightly controlled and their health effects are largely unstudied.We do think that an adult who consumes an occasional energy drink (one a day) is unlikely to suffer harm. But too much can lead to caffeine overdose and health problems, and mixing energy drinks and alcohol is a bad idea. And remember—there is no justification for giving these drinks to children and teens.Seek simpler and safer ways to maintain your energy and stay alert. Get a good night’s sleep. Exercise daily. Eat well. These are the real magic bullets.
