Caffeine & Coffee: How Much Is Too Much?

Thousands of business people rely on caffeine and coffee every day to improve energy levels. Studies suggest that caffeine can be part of a healthy diet for most humans, but too much caffeine could be detrimental to your health.

Caffeine, a natural stimulant found in various beverages and foods, is a central part of many people’s daily routines. From morning coffee runs to energy drinks during the afternoon slump, caffeine is consumed worldwide. However, there comes a point when indulging in this energising compound can have negative effects on health. In this article, we delve into the topic of caffeine consumption, exploring its benefits, potential risks, and most importantly, how much caffeine is too much.

Coffee is a brewed drink prepared from roasted coffee beans, the seeds of berries from certain flowering plants in the Coffea genus. From the coffee fruit, the seeds are separated to produce a stable, raw product: unroasted green coffee.

Up to 400 milligrams (mg) of caffeine per day appears to be a safe amount for most healthy adults. This is roughly the amount of caffeine in four cups of joe.

Exceeding this amount may cause these unpleasant side effects:

  • Restlessness
  • Dizziness
  • Anxiety
  • Fast heartbeat
  • Insomnia
  • Irritability
  • Tremors
  • Upset stomach

If you experience these symptoms after drinking a cup of coffee, you may be sensitive to caffeine and should consider avoiding caffeinated drinks altogether.

It’s not all bad though. Here are 7 health benefits of drinking coffee:

  • Improves your energy levels and concentration;
  • Assists you in burning fat;
  • Enhances your physical performance;
  • Contains essential nutrients and antioxidants;
  • Lowers the risk of Type 2 diabetes;
  • Lowers the risk of Parkinson’s disease;
  • Protects you from Alzheimer’s disease and dementia.

So is coffee good for you? The answer is Yes! But it depends on the kind of coffee and the quantity.


Caffeine can be a valuable tool for enhancing alertness, focus, and performance when consumed in moderation. However, excessive caffeine intake can lead to a range of health issues, including sleep disturbances, increased heart rate, and anxiety. Understanding your body’s tolerance and consuming caffeine mindfully is crucial for reaping its benefits while avoiding potential risks. As a general guideline, aim to stay within the recommended daily limit of up to 400 mg of caffeine, but always prioritise your individual health and well-being above all else.
