That 8-ounce cup of coffee has about 100 milligrams of caffeine, although coffees and teas vary widely in their caffeine content depending on how they are brewed. For example, CR finds that 8 ounces of Starbucks coffee has 165 milligrams of caffeine. CR says safe limits of caffeine are up to 400 milligrams per day for healthy adults, 200 milligrams a day for pregnant women, and up to 45-85 milligrams per day for children, depending on weight.
One day, a 16-ounce cup had 259 milligrams of caffeine. Another day, the same size coffee contained 564 milligrams. Tea offers a much gentler lift. A cup generally contains from 30 to 90 milligrams of caffeine, depending on the variety and how long the bag is steeped.
