Many people insist they cannot make it through a morning without their favorite cup of coffee. For some, the taste of the coffee might be a secondary consideration. In such instances, caffeine, and the jolt it provides on sleepy, early mornings, is the true allure of that morning cup of joe.

Consuming caffeine in moderation should not have an adverse effect on many people’s overall health. However, it’s important to learn just how much caffeine is in your morning coffee. That’s because the side effects of consuming too much caffeine can be severe. According to the U.S. National Library of Medicine, consuming more than 400 milligrams of coffee can be harmful. The potential side effects of overconsumption of caffeine include:

• restlessness and shakiness

• insomnia

• headaches

• dizziness

• rapid or abnormal heart rhythm

• dehydration

• anxiety

• dependency
