6 ways energy drinks can hurt your body | MNN – Mother Nature Network
The concept seems relatively innocuous. Get a burst of energy by drinking something out of a colorful can that looks an awful lot like a soda. But energy drinks have a lot more going on under that pop top.
Here’s a look at some of the potentially harmful ingredients and some of the health problems that can result if you drink too many of the beverages that promise a buzz.
A lot of the energy you get from an energy drink comes from caffeine. The quantity can vary widely — from 80 milligrams in an 8.4-ounce Red Bull to 357 milligrams in a 16-ounce Bang energy drink — according to the Center for Science in the Public Interest. Compare that to 35 milligrams in a 12-ounce Coke or 150 milligrams in a 16-ounce Starbucks cappuccino or 330 milligrams in a regular 16-ounce Starbucks coffee.
A 2017 study published in the Journal of the American Heart Association says energy drinks are more dangerous to your heart than drinks with just caffeine alone. The study author is Dr. Emily Fletcher, deputy pharmacy flight commander from David Grant USAF Medical Center in California. She and her colleagues began studying the effects of energy drinks on the heart after research showed 75% of military personnel on the base had consumed an energy drink. They found that one 32-ounce energy drink caused elevated blood pressure and could cause a life-threatening arrhythmia.
Experts generally agree that it’s OK for most healthy adults to consume up to 400 milligrams of caffeine a day, reports the Mayo Clinic. But when it comes to adolescents, the American Academy of Pediatrics recommends they get no more than 100 milligrams a day.
If you’re downing several of these drinks (and maybe also drinking coffee and caffeinated sodas), it’s easy to exceed the daily recommended limit for caffeine.
Too much caffeine can cause a rapid heartbeat and high blood pressure. In addition, it can cause side effects such as:
Caffeine can cause more serious issues for people who have heart problems or who take certain medications.

Energy drinks can have between 21 and 34 grams of sugar per serving, according to a 2013 study in Pediatrics in Review. Sometimes the sugar comes in the form of high fructose corn syrup.
“Users who consume two or three energy drinks could be taking in…4 to 6 times the maximum recommended daily intake [of sugar],” the authors write. They point out that young people who regularly consume energy drinks could have a higher chance of obesity and dental issues.
Over time, the consumption of many energy drinks could possibly also lead to type 2 diabetes.
Blood pressure and heart disease
Drinking just one 16-ounce energy drink can increase your blood pressure and stress hormone levels, according to a study by Mayo Clinic researchers published in the Journal of the American Medical Association. Although those changes are short term, they could increase a person’s long-term risk of developing heart disease.
“In previous research, we found that energy drink consumption increased blood pressure in healthy young adults,” said study co-author Anna Svatikova, M.D., Ph.D., in a statement. “We now show that the increases in blood pressure are accompanied by increases in norepinephrine, a stress hormone chemical, and this could predispose an increased risk of cardiac events — even in healthy people.”
A 2019 study published in the Journal of the American Heart Association found that energy drinks can raise blood pressure and impact the heart’s electrical activity.
Liver issues

In a November 2016 case study, a man reported signs of dark urine, abdominal pain and jaundice. His consumption of four to five energy drinks a day over the course of three weeks resulted in the buildup of niacin in his liver, leading to the development of hepatitis. Niacin, also known as vitamin B3, appears in at least three popular energy drinks — Red Bull, Monster and Rock Star — and it has been shown to lower cholesterol. Too much, however, isn’t good for your body. In addition to hepatitis, too much niacin in your body can also increase your diabetes risk.
In June 2016, a woman in Devon, England, was found to have a liver twice its normal size, thanks to drinking 20 cans a day of energy drinks, reported The Telegraph. When doctors saw the woman’s MRI scan, they originally thought she was an alcoholic because of her liver damage, the paper reported.
In 2013, Dr. Brian Huang treated a 36-year-old patient who came in with severe abdominal pain at Cedars Sinai Medical Center. Although the man admitted to some episodes of binge drinking, he also said that he drank three energy drinks every day for the past year. His liver function deteriorated to the point that he needed a liver transplant.
“As energy drinks have become increasingly popular over the years, their ingredients are being looked at more closely, many which do not have a well-established safety profile. Some of these products have even been banned in other countries. While drinking modest amounts of energy drinks may be relatively safe, frequent consumption over an extended period of time has been linked with liver injury,” said Dr. Huang in the study.
Taurine is an amino acid commonly found in energy drinks. Some studies suggest it may help boost athletic performance, according to the Mayo Clinic. Other studies suggest that when taurine is combined with caffeine, it can increase mental ability.
Because the two ingredients intensify each other’s effects, they may cause issues with the heart, Fahad Ali, an internal medicine resident at Guthrie Robert Packer Hospital in Sayre, Pennsylvania, told U.S. News & World Report. Ali and his colleagues saw young male patients who were experiencing chest pain, heartbeat issues and cardiac arrest, but no clogged arteries, family history of heart disease or other usual causes of heart issues.
The doctors eventually found a link. “We [dug] down more in the history and found that those patients were consuming energy drinks every day,” Ali said.
Ginseng is an incredibly popular herbal supplement because of the belief it can treat or prevent many illnesses. It is purported to help ease stress and fatigue and increase memory, energy and athletic performance.
Possible side effects from too much ginseng include rapid heartbeat, headache, appetite issues, vertigo, fever and insomnia.
However, some studies say the amount of ginseng found in energy drinks is likely not enough to either cause problems or be beneficial.
