Over half the FDA daily limit in one serving. The tracker will flag stacking a second one — and the cutoff calculator will push this earlier than you expect. At 225 mg per venti (3 shots), this drink is 56% of the FDA's 400 mg daily ceiling for healthy adults.
Iced Ventis get a third shot — hot ones don't. Same drink, different bedtime math.
