Red Bull is a popular but controversial energy drink. Most of the concern has centered around its caffeine content. At least that's the case in this country, but some other countries have banned Red Bull - not because of the caffeine, but because of another ingredient called Taurine.
Each eight ounce can of Red Bull contains 1,000 milligrams of Taurine. Eight ounces of "Monster Energy" contains the same amount. The concern is little is known about putting Taurine into the body when most of that natural amino acid is already centered in the heart muscle.
So, Weill-Cornell Medical Center is calling for an investigation. "I think it would be a good idea for somebody to do some more detailed investigations of its cardiovascular effects in particular combinations with caffeine, since it's been a concern," said Neil Harrison, PhD, Weill-Cornell Medical Center Neuropharmacology.
Taurine is a synthesized form of that amino acid. France blocked the sale of Red Bull in 1996. Only this summer, did France finally approve it, with a warning urging ‘moderate consumption'.
Similar labeling appears on cans sold in Canada. Red Bull is not yet authorized for sale in Denmark and Norway. Here in America, Monster Energy cans already wear this label - encouraging drinkers to limit themselves to just 3 cans a day, and it says not recommended for children, pregnant women or people sensitive to caffeine.
