When should i drink energy drinks?

Answer 1

There are three kinds of "energy" drinks.

Each one fulfils a different function.

Firstly you have straight forward energy drink such as Red Bull. Not everyone reacts well with them, most kids don't so never give them to under 16yr olds, and some states and countries have banned then due to the levels of caffeine and taurine. They're drunk in vast quantities elsewhere and should ideally be used sparingly and before you fatigue, not once you're fatigued. If you have a pre-existing heart complaint you should avoid Red Bull and the like especially if combined with elevated HR levels such as exercise or trauma.

Secondly you have isotonic / electrolytes drinks or powders that you add to water.

Thirdly you have carbohydrate drinks and powders which you again add to water.

I don't know any mtn bike racers, amateur or professional who don't use both of the above powders in their bladders / water bottles every training ride or race or event. That's how much we rate them.

Answer 2

According to most studies, you should be at least 15 before consuming an energy drink.
