Great Britain FAQ and serving size.
Estimated caffeine remaining over time
These figures apply CaffCalc’s exponential model to the adjusted 34 mg starting value. They are calculations, not measurements of caffeine in a particular person.
| Hours elapsed | 3-hour half-life | 5-hour half-life | 7-hour half-life |
|---|---|---|---|
| 0 | 34 mg | 34 mg | 34 mg |
| 3 | 17 mg | 22.4 mg | 25.3 mg |
| 5 | 10.7 mg | 17 mg | 20.7 mg |
| 8 | 5.4 mg | 11.2 mg | 15.4 mg |
| 10 | 3.4 mg | 8.5 mg | 12.6 mg |
| 12 | 2.1 mg | 6.4 mg | 10.4 mg |
With the central five-hour model, the estimate falls below 25 mg after approximately 2.2 hours. The faster and slower columns show why one fixed clearance time should not be treated as a personal fact.
