How to know if you drink too much caffeine

The first important thing is to note that everyone can have a different threshold, as each of us metabolizes caffeine differently. Some people are fast metabolisers and others are slow metabolisers, so this will affect the degree and threshold of tolerance.

The general rule of thumb is to stick to 200 mg of caffeine if you are a slow metabolizer (i.e. 2 cups of coffee), and take up to 400 mg of caffeine if you are a fast metabolizer (equivalent to about 4 cups of coffee).

If you don't pay attention to the doses of caffeine you ingest, here are the 10 side effects that you might find:

  • rapid heartbeat (tachycardia or palpitations)
  • nervousness
  • anxiety
  • high blood pressure
  • sodium and water retention
  • electrolyte imbalance
  • dehydration
  • insomnia
  • headache
  • digestive problems (such as frequent bowel movements, indigestion, acid reflux)

Be careful what you drink

Often excessive levels of caffeine can result not only from coffee, but also from the consumption of energy drinks, which often contain much more caffeine than coffee itself.

It is also important to consider other effects and ingredients found in most energy drinks; in fact, you should know that there could be up to 35 grams of sugar in a drink medium sized. (Read also: Coffee does not increase the risk of heart arrhythmias)

What to do if you drink too much caffeine

The first thing to do is to look at the quality of caffeine you're drinking and, above all, read the list of ingredients in your caffeine-based energy drink.

In addition, you can also undergo a genetic test, to see if you are a fast metabolizer or a slow metabolizer of caffeine, since in this way you can be able to understand how much to take per day and what is the limit not to exceed. Hence, one of the most important steps is to understand of how much caffeine do you need to ingest and over what period of time, so as to reap only the benefits without the negative effects. 

In fact, it should be noted that it has been shown that our performance can improve if we take small doses of caffeine over a long period of time. 


In conclusion, remember that everyone is different and everyone will have different set points regarding how much caffeine they can tolerate or should drink throughout the day. It is also important to keep an eye on any signs related to the excessive consumption of caffeine, in order to take care of your health.
