How much caffeine is too much? Most people can consume up to 400 milligrams of caffeine in a day without serious side effects. That's around five cups of espresso.
However, certain medications and health conditions can change the way your body metabolizes caffeine. For example,
birth control pills can slow the breakdown of caffeine in the body, so its side effects can become more pronounced.
Also, most health experts recommend that pregnant women avoid consuming more than 200 milligrams of caffeine (around 2 cups of coffee) daily.
But what's the right dose for you? You can use an online caffeine calculator to get a rough estimate, but it doesn't take your individual metabolism into account.
Some people feel serious side effects after a single cup of coffee, while others binge on energy drinks without any noticeable problems. If you want to find your ideal dose of caffeine, you might have to experiment, but please consult your doctor before going overboard.
