Heavy marketing of energy drinks, packaged 'health drinks', packaged fruit juices and supplement shakes are all responsible for people having the impression that these are healthy!
Nothing is further than the truth! These drinks - similar to all packaged / processed modern food contain mostly sugar, caffeine and a lot of other chemicals mixed in which are fully unnatural and nothing but lab formulations.
Stick to natural drinks like water and coconut water for your hydration! Drink these when you are thirsty according to your thirst levels
