Your body quickly absorbs caffeine. But it also gets rid of it quickly. Processed mainly through the liver, caffeine has a relatively short half-life. This means it takes about five to seven hours, on average, to eliminate half of it from your body. After eight to 10 hours, 75% of the caffeine is gone.For most people, a cup of coffee or two in the morning won't interfere with sleep at night.Consuming caffeine later in the day, however, can interfere with sleep. At high levels (more than 744 milligrams/day), caffeine may increase calcium and magnesium loss in urine. 2  But recent studies suggest it does not increase your risk for bone loss, especially if you get enough calcium. 3  You can offset the calcium lost from drinking one cup of coffee by adding just two tablespoons of milk.
