Energy Drinks: Hazardous to Your Health?

Sept. 24, 2008 — Caffeinated energy drinks that promise super alertness — and in some cases suggest better sports execution — should carry names that specify their amount of caffeine, says a Johns Hopkins College researcher.

Drinks with the highest caffeine content ought to too caution of potential health perils, says Roland Griffiths, PhD, a professor of psychiatry and neuroscience at Johns Hopkins University School of Pharmaceutical, Baltimore, and senior author of a new report on the beverages.

“Many of these drinks don’t name the caffeine content,” he says, and some vitality drinks contain as much caffeine as found in 14 cans of soda.

The industry asks to differ, with representatives indicating out that most “mainstream” vitality drinks contain the same sum of caffeine, or indeed less, than you’d get in a glass of brewed coffee. If labels listing caffeine substance are required on energy drinks, they should too be required on coffeehouse coffee, says Maureen Story, PhD, a representative for the American Refreshment Affiliation.

Vitality Drinks: The Back Story

Since Red Bull, the first vitality drink to hit the U.S. market, launched in 1997, the showcase has boomed, Griffiths says, presently totaling at least $5.4 billion a year within the U.S. Hundreds of brands are available.

Although the FDA limits the caffeine contents of cola-type delicate drinks to 71 milligrams per 12 fluid ounces, no such restrain is required on vitality drinks, Griffiths tells WebMD.

“Creators of so-called “energy” drinks for the most part advertise them as dietary supplements,” says Siobhan DeLancey, an FDA representative. Dietary supplements are directed differently than food. The FDA does not approve or audit the products before they are marketed.

Vitality Drinks: Caffeine Substance

Griffiths and his colleagues contacted more than two dozen creators of energy drinks, asking for caffeine substance. Here are some of the discoveries:

(The caffeine content is in milligrams per serving. Although serving sizes vary, Griffiths fights that most people will drink the whole can, anything the number of ounces.)

Ruddy Bull: 80 milligrams per 8.3-ounce serving Tab Vitality: 95 mg per 10.5-oz serving Beast and Rockstar: 160 mg per 16-oz serving No Fear: 174 mg per 16-oz serving Fixx: 500 per 20-oz serving Wired X505: 505 mg per 24-oz serving

In comparison, according to Griffiths:

Brewed coffee: 200 milligrams per 12-oz serving Moment coffee: 140 mg per 12-oz serving Brewed tea: 80 mg per 12-oz serving Mountain Dew: 54 mg per 12 oz. serving Dr. Pepper: 41 mg per 12-oz serving Pepsi Cola: 38 mg per 12-oz serving Coca-Cola Classic: 34.5 mg per 12-oz serving Canned or bottled tea: 20 mg per 12-oz serving

A few of the energy drinks have lower caffeine substance, Griffith says. Among the lower doses:

Bomba Energy has 75 mg per 8.4-oz serving Whoop Ass has 50 mg per 8.5-oz serving

Energy Drinks: The Report

Energy drinks are prevalent with high schoolers and young adults, Griffiths found in his inquire about. In a 2007 overview of 496 college students, 51% said they had expended at slightest one energy drink amid the past month.

Bad reactions to energy drinks have been detailed to U.S. poison control centers, Griffiths writes in the report, published within the journal Sedate and Liquor Reliance. From 2002 to 2004, he says, 41 cases of caffeine manhandle from caffeine-enhanced beverages were detailed.

In a report of nine cases of antagonistic responses to the energy drink Redline, the patients detailed queasiness and spewing, high blood pressure, tremors, tipsiness, and numbness.

Data also propose those who drink the energy drinks may combine them with alcohol, Griffiths tells WebMD. In the college student overview, 27% said they blended alcohol and energy drinks at least once within the past month. One peril to that: Clients may feel alert sufficient to drive, indeed if they are inebriated.

Griffiths worries that the energy drinks are some of the time “gateways” to utilize of other substances. In one study, college students who used energy drinks were more likely to afterward use stimulants for recreational use, he says.

Energy Drinks: Industry View

Storey, of the American Beverage Association, took special case with Griffiths’ see. “It’s a survey, not a consider,” she says of his report. “We need to use caution around taking too much out of one survey. He looked at a few thinks about.”

In a articulation issued by the affiliation, authorities note that most “mainstream” vitality drinks regularly contain half the caffeine found in normal coffeehouse coffee. A 16-oz cup of coffeehouse coffee has about 320 milligrams of caffeine, according to the statement, while a ordinary 16-oz mainstream energy drink has 160 mg.

In case names ought to be required on energy drinks, Story says, coffeehouse coffee ought to also be required to label caffeine substance.

Most companies advertise their vitality drinks responsibly, the association fights. Only a few companies allow the products unlawful or suggestive names (such as Cocaine, an energy drink that triggers discussion).

“Vitality drinks can be part of a balanced lifestyle when devoured sensibly,” the statement peruses.

Vitality Drinks: Griffiths’ Reaction

Griffiths stands by his proposal to require warning labels on the energy drinks with the highest caffeine content, although he isn’t certain what that threshold should be.

There’s a difference, he says, within the marketing of energy drinks and showcasing of traditional caffeine refreshments. The vitality drink creators, he says, ”are promoting to powerless populaces.”
