Many energy drinks have high amounts of caffeine and other ingredients that can cause temporary increase in blood pressure. Unlike coffee, with which most people do not overdo it, energy drinks are sometimes consumed frequently and in large quantities. This can keep your blood pressure high. "Energy drinks offer a dose of highly concentrated caffeine, which makes it hard to stop when you feel you have drunk too much," says Joy Bauer, editor of nutrition and health for "Today Show" of the NBC.
Caffeine and blood pressure
The amount of caffeine in an energy drink ranges from 75 to 400 mg, according to Dr. Steven E. Lipshulz, chief of pediatrics at the University of Miami School of Medicine. Only 200 mg of caffeine can cause an increase of 14 points in your systolic pressure, or the higher number in a reading, and an increase of 13 points in the diastolic pressure, the lower number in a reading. Most people who like energy drinks drink them more quickly than other drinks, according to the University of Southern California. They also drink more often. Increased consumption, along with incomplete warning labels on these products can lead to an overdose of caffeine, according to the University of Southern California.
Other Energy Drink Ingredients
In addition to caffeine, energy drinks contain herbs and supplements that are not regulated by the U. S. Food and Drug Administration. According to the University of North Texas, both ginseng and guarana, typical additives in energy drinks, can increase your blood pressure. In high doses, yohimbine can also increase heart rate and blood pressure. Little or no research has been done on the interaction of these supplements with caffeine.
Children and Adolescents
The American Pediatric Association in 2011 issued a warning that children and adolescents should not consume energy drinks because of the effect of caffeine on their heart rate, blood pressure and other bodily functions. In a March 2011 article in the journal "Pediatrics," Sara Seifert, a researcher at the University of Miami Leonard M. Miller School of Medicine, wrote that children under 19 accounted for almost half of all overdose cases. caffeine reported in 2007. Teens and young adults consume between 30 and 50 percent of the energy drinks sold in the United States. The FDA limits the amount of caffeine in soft drinks, but not in energy drinks, which are considered supplements and not food.
