    How much caffeine is too much?

    The FDA cites 400 mg a day as an amount not generally linked to dangerous, negative effects in most healthy adults. People react differently, and some should have less. If you're pregnant, breastfeeding, take medication or have a heart condition, ask your doctor how much is right for you.

    Every drink's caffeine by size is on its own page in our Starbucks drinks list. For calories and sugar too, use the Starbucks calculator.

    Caffeine values are Starbucks' published approximations for the standard recipe. Brewed coffee varies by bean and batch.
