Key Messages
Do you want to live in a world without caffeine? We sure don’t. Yet conflicting messages about caffeine and its sources continue to percolate, leaving many Americans unsure of whether they can enjoy their daily cup of joe. Good news! Multiple health authorities agree – moderate amounts of caffeine are safe and have been associated with various health benefits.
How much caffeine can you enjoy each day? The Food and Drug Administration says up to 400mg/day for most people. What does that translate to? One 8 oz cup of coffee (the most popular source of caffeine for Americans!) is about 100mg/caffeine, 1 oz of espresso is about 60mg and 8 oz of black tea is about 50mg.
Remember, caffeine isn’t just found in coffee and tea—it can come from many sources. Caffeine from soda, energy drinks, even foods like chocolate and coffee-flavored desserts can add up throughout the day. Curious how you measure up? The IFIC Caffeine Calculator is your new best friend!
