How much caffeine is too much?
For most healthy adults, the FDA points to about 400 mg of caffeine a day — roughly four cups of coffee — as an amount not generally associated with negative effects. That’s a population guideline, not a target: sensitivity varies a lot, and what’s fine for one person can cause jitters, a racing heart, or poor sleep in another.
This tracker adds up your typical drinks so you can see where your day lands and adjust — especially in the afternoon and evening.
Where caffeine adds up
- Brewed coffee: ~95 mg per cup (large coffees can be 200 mg+).
- Espresso: ~65 mg per shot.
- Tea: ~47 mg per cup.
