According to a new study, consuming enough energy drink can lead to certain concerning characteristics in heart function and blood pressure outside of those seen solely from caffeine. Energy drinks are extremely popular with hundreds of versions currently available for sale. Unfortunately, these beverages have become associated with emergency-room visits and even death. While the makers of energy drinks claim that the products pose no more dangers than those related to caffeine, the evidence does not necessarily reflect this assertion.

While the dangers of energy drinks are usually related to their caffeine content, it is the other ingredients which may pose the risk. The physical changes in a group of subjects (both male and female) were observed after the subjects had consumed an energy drink and a caffeinated beverage that lacked the other types of ingredients energy drinks are known for. These additional ingredients include 4 ounces of sugar, taurine, B vitamins, and other contents found in brand-name energy drinks like Red Bull, 5-Hour Energy, and Monster. The results showed certain concerning cardiovascular changes including an increase in blood pressure after the consumption of energy drinks. Be smart and play it safe. If you choose to consume energy drinks, do so in moderation and ensure you do not suffer from any sort of cardiovascular conditions or issues or other health ailments that could result in a visit to the emergency room or worse.
