The half-life of caffeine

84 viewsBiologyOther

It’s ~6 hours. A person takes in 200mg at 6:00 each morning. They have 12.5mg in their system at 6:00 the next morning. The cycle continues. Each morning, they take in 200mg of caffeine and have more caffeine in their system than the day before until they have thousands of mgs of caffeine in their system. Yes?

Putting aside for the moment that this is a rule of thumb.

You are ignoring the fact that the following morning the person has slightly more caffeine in their system, so the rate at which it leaves their system is higher. This continues each day until the amount removed over a 24 hour period is equal to 200mg, at which point you have a steady state.
