What’s in energy drinks that provides the “kick” that one otherwise doesn’t get from coffee, tea, etc?

Question

Should mention that I drink only no sugar drinks, so it can’t be that, and a single can of what I have is usually no more than 200MG of caffeine

Edit: Appreciate your responses. Thank you for the explanations and insights

Answer 1

Niacin!! It causes a flush feeling. Combined with caffeine it gives a mental association of that being the same as the caffeine.
