The half-life of caffeine, the time it takes for your body to eliminate half of the dose, is approximately 5 hours for an average healthy adult. This means if you consume 200mg of caffeine, around 100mg will still be active in your system about five hours later. However, the duration of effects can vary significantly based on individual differences.
