Problems existing energy drinks

What are the problems of the existing energy drinks?

The existing enery drinks contain too much caffeine. One 250 ml can of Red Bull Energy Drink contains 80mg of caffeine, about the same amount of caffeine as in a cup coffee, the problem is also that a lot of teenagers are drinking this, even sometimes more than one can.
The message we wanna bring over to the companies, is that our new energy drink prevent this kinds of problems. That all those existing energy drinks contain too much caffeine.
Our target group are both male and female, how whats that energy boost, but don't wanna have to drink all that caffeine.

we want people to be more carefull about the amount caffeine they drink! People can drink energy drinks, but this can be done in a much healthier way!
