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.

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.
