Healthy Limits

The FDA recommends consuming a maximum of 400 milligrams of caffeine a day. That’s a little over six espresso shots. But that’s a healthy limit, so it doesn’t mean that drinking seven espressos will kill you!

The biggest thing to keep in mind is that caffeine tolerance varies. Your ability to handle a cup or three of coffee depends on things like your weight, what you’ve eaten, and how sensitive you are to caffeine. If you have questions about your caffeine intake, talk to your doctor.

How much caffeine is too much?

According to experts, between 5 and 10 grams of caffeine is a potentially lethal dose. We typically measure caffeine in milligrams, so that would be 5,000 to 10,000 milligrams.

Although coffee has a lot of proven health benefits, like protection from diseases like Alzheimer’s, Parkinson’s, and some types of cancer, drinking too much can harm your health. Just like drinking too much alcohol, caffeine can build up in your blood, causing symptoms like heart problems, insomnia, sweating, dizziness, and anxiety.

How many shots of espresso will kill you?

So how much espresso is that? The average 8-ounce cup of coffee has 95 milligrams of caffeine, and the typical shot of espresso has 65 milligrams. To drink 10,000 milligrams of caffeine, you’d have to consume 156 shots of espresso or 105 cups of coffee in one day.

That’s an incredible amount of coffee, and your body likely wouldn’t let you get that far anyway. Some of the symptoms of caffeine overdose include nausea and vomiting, which is your body’s way of getting rid of potentially dangerous toxins.


The Bottom Line

To enjoy your espresso without risking your health, you’ll probably want to limit yourself to a maximum of six single espresso shots in one day. But how many shots of espresso will kill you? Depending on factors like your weight and caffeine sensitivity, drinking 156 shots of espresso or 105 cups of coffee in a single day could kill you! Luckily, that’s a pretty extreme number that’s easy to avoid. You want to enjoy your espresso, right?
