Caffeine takes a certain amount of time to work through your system. One study some years ago showed that the half-life of caffeine in healthy adults is 5.7 hours (see source). This means if you consume 200mg of caffeine at mid-day, you would still have 100mg in you at around 5.45pm.irst, youâre right about caffeine having a half-life of around 6 hours. If you consume 200 mg of caffeine, youâd still have 100 mg in you after 6 hours. Compromised liver function increases half-life by slowing metabolism.
