They have a lot more caffeine than an 8-ounce cup of coffee.. 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.
The caffeine content in a cup of coffee is highly variable, ranging from 50 to 400+ mg per cup. A small home-brewed cup of coffee could contain 50 mg, while a big 16 oz Starbucks grande can contain over 300 mg. As a general rule, you can assume that an average 8 ounce cup of coffee contains around 100 mg of caffeine. Several sources suggest that 400 mg of caffeine, or 4 cups of coffee, are safe for most healthy adults (3, 5). However, many people (including myself) drink much more than that without any issues.
