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.
In general, 200 milligrams of caffeine is equal to one 12-ounce cup of coffee, but coffee drinkers should be aware that there can be tremendous discrepancies in different brews. For example, a grande 16-ounce Starbucks brewed coffee has 320 milligrams of caffeine.
