Key Messages

  • What is caffeine? Caffeine is a natural stimulant found in familiar favorites like coffee and tea. It can also be produced synthetically and added to foods and beverages. As one of the most studied ingredients in the world, caffeine is known for its ability to enhance alertness – and when consumed in moderation, it’s considered safe for most healthy adults.[1],[2],[3]
  • What are some foods with caffeine? Coffee and tea are the most well-known foods with caffeine, but they are not the only ones. You can also find it in sodas, energy drinks, chocolate and coffee-flavored treats.
  • How much is safe, and what is the caffeine content for certain foods? The Food and Drug Administration says up to 400 milligrams of caffeine per day is safe for most people to consume.[4] That’s roughly four 8-ounce cups of coffee. Other common sources include espresso (60 mg per 1 oz) and black tea (50 mg per 8 oz).
