Are Caffeine and Pre-Workout Drinks Ototoxic?

Just wondering if anyone knows whether or not caffeine is ototoxic and also pre workout drinks and protein??

Pre workout drinks contain mostly caffeine but have slot of other ingredients designed to increase mental alertness and give a "pump" during weight training.

 

Not sure about pre but protein is just a protein supplement. It contains protein which you find in food, with additional sugars for flavouring etc. If protein supplements were ototoxic then so would every food on earth

 

There is a crapload of different products on the market. It's virtually impossible to give an answer that would be true for all of them.

I wouldn't be too concerned about ototoxicity, however I would not recommend caffeine before workout. Your blood pressure will thank you.
