There are many benefits to drinking coffee every day ¡ª from disease-fighting antioxidants to improved memory and longevity ¡ª?but when it comes to your caffeine habit| there really can be too much of a good thing.
Just how much caffeine is too much? For the average person| up to 300 mg of coffee a day| or two to four cups of the average brewed coffee| is a moderate amount that isn’t harmful. But once you hit more than four cups| you may experience less-than-desirable side effects. Drinking more than 500 mg every day| in fact| can induce anxiety| insomnia| and muscle tremors and can even lead to increased heart rate and blood pressure| headaches| or digestion issues.
If you want to stay away from the caffeine jitters| then limiting yourself to under four cups of coffee per day is a perfectly reasonable plan. However| you may be surprised by how much caffeine is in your favorite caffeinated beverage; it can be much more than you think! See how much caffeine is in your favorite drink.
