I am interested to find out how long the side effects of caffeine last once you stop taking it?
4 Nov 2012
Caffeine is fully absorbed by the digestive system in approximately 45 minutes, according to the Coffee Science Information website. Typically, the peak of concentration is 15 to 120 minutes after caffeine is consumed. Caffeine stays in the bodies of men for five to nine hours, but the amount of time is reduced by 30 to 50 percent in smokers. The length of stay for caffeine in women using oral contraceptives is approximately 12 to 15 hours, and can be as long as 15 hours in pregnant women as well, according to the Coffee Science Information Centre and the International Coffee Organization.
