However, its peak of action occurs between 30 and 60 minutes after consumption, depending on each person’s metabolism and the form in which it was ingested (capsule, liquid, etc.). The substance remains in the body for three to six hours, until it is metabolized by the liver and excreted in the urine.

Caffeine has an average half-life of eight hours, which means 200 milligrams at 7:00 am becomes 100 milligrams at 3:00 pm and 50 mg at 11:00 pm. Hare that caffeine is also present in cola-based soft drinks, cocoa and various teas (black, mate, green etc).
