How it compares
Dark Chocolate Bar (70–85%) 80 mg
Green tea (8 oz) 28 mg
Black tea (8 oz) 47 mg
Brewed coffee (8 oz) 96 mg
Monster (16 oz) 160 mg
Bang (16 oz) 300 mg
Roughly a standard cup of coffee's worth. Fine in the morning; for an average metabolizer, finish it a few hours before bed. At 80 mg per 3.5 oz bar, this drink is 20% of the FDA's 400 mg daily ceiling for healthy adults.
A full dark bar is a cup-of-coffee-equivalent hiding in dessert.
