Yes, energy drinks can contain as much as 10 times the caffeine of regular soft drinks.

Thatís why a new study recommends that energy beverages like Red Bull and Rockstar include a warning about the health risks of ingesting too much caffeine.

So how much caffeine is too much? It depends on the consumer. But generally, experts say that anything in the ballpark of 200-300 milligrams of caffeine per day is okay -- thatís the equivalent of two or three cups of coffee.

But when you hit the 500 to 600 milligram level that could be too much. Overdoing your caffeine intake can cause restlessness, anxiety, irritability, headchaches, abnormal heart rhythms and other symptoms.

According to a report authored by researchers at Johns Hopkins University, a typical soft drink has around 35 milligrams of caffeine. Rockstar, a top-selling energy drink, has 160 milligrams. The energy drink Wired X505 has a 505 milligrams of caffeine.

The FDA doesnít limit caffeine in energy drinks and doesnít require warning labels. The studyís authors think warning labels are necessary though, to alert energy consumers to just how caffeine theyíre putting in their bodies.

And now you know.
