Caffeine; is it harmful?


Caffeine today is considered the most commonly used mind-altering drug in the world. Some of its benefits include: the ability to make you more alert, improved concentration, enhanced mood and a boost in your energy.
So what's the harm?
Medical experts say that while moderate caffeine intake (200 to 300 milligrams, or about two to four cups of brewed coffee a day) isn't likely to cause harm, too much can noticeably affect your health.
According to staff at the Mayo Clinic, heavy daily caffeine use—more than 500 to 600 mg a day, or about four to seven cups of coffee—can cause the following negative side effects.
