Tag: Caffeine elimination

The average half-life of caffeine in a healthy adult is approximately five to six hours, meaning half the amount consumed remains in your body. However, the time it takes for caffeine to completely leave your system varies significantly from person to person.

According to the FDA, the half-life of caffeine can range from 1.5 to 9.5 hours, though the average is about five hours for healthy adults. Understanding how is caffeine eliminated from your body is key to managing its stimulant effects and improving sleep quality.
