Many people can’t live without their daily coffee fix, and it’s ok to drink coffee every day. In fact, it may be good for you.

A 2015 study in the journal Circulation found that moderate coffee consumption (three to four cups daily) was associated with an 8 to 15 percent reduction in the overall risk of death. 

  • That said, it is possible to have too much of a good thing. The Food and Drug Administration (FDA) says healthy adults can consume up to 400 milligrams a day of caffeine (about four or five cups of coffee) without dangerous, negative effects. 
  • However, not everyone can drink even that much. Some people are naturally more sensitive to the effects of caffeine, certain medications may make people more sensitive to caffeine, and people who are pregnant, trying to become pregnant, or breastfeeding should not consume that amount. Talk to your doctor if you have any concerns about whether to limit your caffeine intake. 
  • The FDA has not set a level of caffeine consumption that is considered safe for children, but the American Academy of Pediatrics discourages the consumption of caffeine and other stimulants by children and adolescents.
