Which one should you pick?
Take brewed coffee when you want the smallest dose of the three, Starbucks cold brew (grande) when you want a middle number without thinking about it, and Starbucks Nitro Cold Brew (grande) when you actually want the 280mg and know how you handle it. If you drink more than one caffeinated thing a day, the useful move is adding the day up against the 400mg reference rather than judging each drink alone.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
