Study: Energy drinks may increase your risk for heart disease

CLEVELAND, Ohio (ABC) - New research suggests that some energy drinks may increase your chances of contracting heart disease.

The ingredient in question is called carnitine. When it reacts with the bacteria in our intestines, doctors say it produces an artery-clogging compound.

Carnitine is most commonly found in red meat but is also a popular ingredient in energy drinks because it helps the body convert fat into energy.

"Carnitine is a cause for concern, I think, because our data really suggests that this is a risk factor for accelerated heart disease," said Dr. Stanley Hazen of the Cleveland Clinic.

Dr. Hazen led this study. He said that while some energy drinks have small amounts of carnitine, others have as much as a porterhouse steak.
