5-hour Energy Extra Strength vs coffee and espresso

How the number behaves

Energy drinks list an exact caffeine number because caffeine is a measured additive: every 1.93 oz shot of 5-hour Energy Extra Strength carries the same 230mg, unlike brewed coffee, where the beans, dose, and brew time move the figure around. That predictability is the one real advantage a can has over a cup: you always know exactly what you drank.

The mistake people make is stacking. One 1.93 oz shot is 57 percent of the 400mg FDA reference, so a can on top of a normal coffee habit adds up faster than it feels like it should. Run the math on your whole day, not the single can.
