How much caffeine is in Aspire Energy?

Aspire Energy is a gentler choice, carrying about 80 mg of caffeine in a 12 oz can, roughly a cup of coffee. Zero-calorie and zero-sugar, it offers a moderate lift without the heavy doses of bigger cans.

Will Aspire Energy affect your sleep?

At 80 mg, Aspire needs around three hours to fall under 50 mg, so a mid-afternoon can is usually clear by bedtime. An evening one may still register a little, but it's far gentler than most energy drinks.
