About 8 in 10 Americans consume some form of caffeine each day. So, how much is safe?

Research shows that consuming up to 400 mg of caffeine a day is safe for most adults — this equals roughly 2-4 cups of brewed coffee. (Note: It's recommended that pregnant or lactating women limit their daily caffeine consumption to 200 mg.) However, consuming more than 400 mg of caffeine a day may increase your risk of heart disease by raising your heart rate and blood pressure over time.

A small change you can make: If you’ve had four cups of coffee in a day and want to have more (we've been there), you can switch to half-caff or decaf.

Did you know?Consuming a moderate level of caffeine (200-300 mg a day) may actually reduce your risk of heart disease.

A small change you can make: If you typically have 3-4 cups of coffee a day, try to cut back by one cup.

Keep in mind, though, that many caffeinated drinks — like soda, energy drinks, and blended iced coffees — contain a good bit of added sugar, and consuming too much can lead to diabetes, a major risk factor for heart disease.

A small change you can make: If you drink multiple sodas per day, try swapping one out for sugar-free sparkling water.

Some people may be more sensitive to the effects of caffeine, depending on their current health conditions and medications. Be sure to discuss your caffeine habits with your primary care provider and/or your cardiologist.
