How much caffeine is too much?

Save

Hi there and thank you for your question!

For most healthy adults, the Food and Drug Administration (FDA) recommends 400mg of caffeine per day - that's roughly 4 to 5 cups of coffee (1). A cup is 8 ounces, which is most likely less than the amount of regular coffee most people pour themselves. Some people are more sensitive to caffeine than others so they can only tolerate a limited amount. However, there are some people who metabolize and break down caffeine faster than others so they can tolerate more. 

The FDA has not set a level for children, but the American Academy of Pediatrics discourages children and adolescents from drinking caffeine (1). 

If you have a health condition (that includes pregnancy and lactation) and/or taking medication, I encourage you to talk to your doctor or healthcare provider about whether you need to limit your caffeine. 

Hope this helps!

 

Cheers,

Anna Ng, RD
