Drinking 32 ounces of energy drink is associated with potentially harmful changes in blood pressure and heart function that are beyond those seen with caffeine alone, according to a new study. – NBC News
The FDA (Food and Drug Administration) states that caffeine in doses up to 400mg, which is about 5 cups of coffee, is recognized as a safe amount.
Many of the energy drinks on the market contain almost the full amount of caffeine recognized as safe by the FDA, plus a concoction of other ingredients like taurine, who’s safety is unknown.
The study showed that individuals who drank an energy drink had drastically different results to those who just drank caffeine (like coffee).
An ECG change known as QTc prolongation and sometimes associated with life-threatening irregularities in the heartbeat was seen after drinking the energy drink, but not after drinking the caffeine beverage, the study team reports. Blood pressure increased by close to 5 points after drinking the energy drink, but by just under 1 point after drinking the caffeine beverage. Blood pressure also remained elevated six hours later. – NBC News
Researches said that this may not be an issue for healthy individuals, but for those with heart conditions should be very cautious with energy drinks.
I get enough energy from coffee alone, so I’ll stay away from the energy drinks.
