I am aware on many cans/bottles of energy drinks it says not to drink too much within a day. For example Redbull cans say not to consume more than 500ml/day. What difference does this have compared to coffee? I have never seen a coffee recommendation other then for pregnant women (not to drink more than 4 cups/day i think). Is anyone aware of a longterm impact of consuming excess energy drinks? I guess they haven’t been around for long enough.
