With lifestyles becoming busier than ever and everyone trying to cram in as many things as they can in a day, caffeinated drinks have risen to stardom over the past few years. Just go take a look in your convenience store and you’ll know what I’m talking about. Fridges stocked full of energy drinks in many different flavors to accommodate people’s needs.

Caffeinated drinks are the best and quickest way to give you a boost of energy, increase mental alertness when needed, and alleviate fatigue so you can tackle that task you have ahead of you.

If you’re someone who regularly drinks coffee, or relies on more than one or two caffeinated beverages a day, have you ever thought of how much caffeine is the limit before it affects your health? Is too much caffeine bad for you?

It wasn’t until recently that I thought of this. I’m someone who loves the morning cup of coffee or two as a wake-me-up and also loves to take a pre-workout energy powder before a gym session. So I did some research on how much caffeine is safe for the normal person in a day.

Research has shown that healthy adults can safely consume between 400-500 mg of caffeine a day without risking any serious health issues and side effects. This amount of caffeine is usually equal to 4-5 cups of brewed coffee, 10 cans of caffeinated soda, or about 2-4 cans of an energy drink (depending on the size of the can).

Many people stay between 150-250 mg of caffeine in a day with their morning coffees. But what happens if you go over this 400-500 mg limit daily?

Can you overdose on caffeine?

Though it’s very rare to die from too much caffeine (you would have to consume 100 cups of coffee a day to maybe do that) some people experience side effects such as:

  • Insomnia
  • Nervousness
  • Restlessness
  • Irritability
  • Stomach upset
  • Fast heartbeat
  • Muscle tremors
  • Nausea


For the average person, it’s very seldom that they will go beyond this amount in a day and experience these side effects. With caffeine consumption, it also depends on the person and their caffeine tolerance. When you consume caffeine on a regular basis, your body adapts to the caffeine, and in a sense becomes caffeine tolerant over time. This can lead to someone needing more and more coffee or energy drinks over time to experience the same alertness and wakefulness that they once achieved with less caffeine.

To sum up the question of: Is too much caffeine bad for you? It really depends on how much you can tolerate. As long as you stay within the guidelines provided and note how your body responds to the caffeine intake and know when to back off, caffeine can help give you a jolt to your day.
