How much coffee is too much coffee? is there a thing as too much coffee? Look - there are several undeniable health benefits linked to daily coffee consumption, and every day its seems scientists gather more hard evidence to strengthen the case.

On average, if you drink the following cups of coffee (black, no milk, no cream, no sugar) per day you'll also benefit from:

  • 35% lower risk of developing type 2 diabetes from 6 to 7 cups.
  • 20% lower risk of being hospitalized for arrhythmia or strokes from 1 to 3 cups.
  • Decreased risk of developing Parkinson's disease (stats not available).
  • Decreased risk of developing cirrhosis and also liver cancer (stats not available).
  • 65% lower risk of developing dementia and also Alzheimer's disease from 3 to 5 cups.

The evidence is overwhelming, so let's raise our mugs and drink up to the magical fountain of caffeinated youth, right? Right? Well, you just hang on to that thought, because a critical question arises here: Is there such a thing as a caffeine overdose?

How much coffee is too much coffee? See, there are many factors involved, and this also varies from person to person, but we'll walk you through absolutely all the details.

The Basics of Coffee & Caffiene

It's paramount that you understand that when we refer to coffee, we are talking about regular, black coffee. This means NO milk, or cream, or sugar.

A standard cup of coffee has roughly two calories, approximately 80-100mgs of caffeine, and packs a powerful source of antioxidants that will get you covered for your daily needs (whether it's caffeinated or decaf, the benefits are the same).

Caffeine Sensitivity and Caffeine Tolerance.

We all react very differently to the substances we consume, and coffee is no different. This is because our unique genetic makeups and the genes responsible for metabolizing caffeine do it through our livers.​

All existing variations give room to something known as caffeine sensitivity, and there are three large groups:

Hyper-sensitive: People in this group get reactive to small amounts of caffeine, sometimes a cup or less will cause them insomnia, accelerated heart beat, and jitters. Also worthy of note, all of the health benefits mentioned above, are not established as true for people under this category.​

Normal: The vast majority of the population lies under this group. They can usually take up to 400mgs of caffeine daily without showing any side effects. All of the studies made about the caffeine benefits are proven right for people with normal sensitivity.​

Hypo-sensitivity: Roughly 1 out of 10 people are born hypo-sensitive to caffeine, which means they can take massive doses (sometimes more than 600mgs per day) and not show any side effect at all. People in this group might not experience the same health benefits from drinking the recommended amount of coffee per day.​

After reading the above groups, can you take a guess at which one you fall under?

On the other hand, we have caffeine tolerance, and this happens when your body slowly generates a natural resistance to the effects of caffeine, as opposed to the first time you had it.

Caffeine tolerance can develop in as early as one day, or take up to four. You can also reset your caffeine tolerance level by detoxing your body completely from it; this can take anywhere between 2-8 weeks.

However, our bodies have simple detoxing protocols for all foreign substances, and they do it now and then, so you don't have to worry about this.​

Simply put, regular coffee drinkers have a higher tolerance for caffeine. So do people with a higher metabolism rate, and women in general when compared to men (unless they are taking contraceptive pills, in which case their tolerance level is up to 33% slower than females who are not on the pill).

Caffeine Concentration in Certain Types of Coffee

Remember how we stated earlier that a regular cup of black coffee has roughly 80-100 mgs of caffeine? Well, now that you can consider yourself some sort of coffee guru, how about we go a little deeper?

Let's analyze the amount of caffeine found in the following 8 oz samples, measured consistently over time. After all, plain black coffee can't be everyone's vice:

  • 3-12mgs for decaffeinated.
  • 27-173mgs for instantaneous.
  • 102-200mgs for plain and brewed.
  • 240-720mgs for espresso.

Notice the limits? Maybe your wondering why the heck there such a broad range in the first place? Well, the caffeine molecule is a natural occurrence in around 60 different types of plants.

The biological evolution of a certain plant, combined with environmental conditions, and even the brewing method used, all play a role in the amount of caffeine a sample will have. Also different types of coffee beans will have different levels of caffeine, such as:

  • 1.13% for Ethiopian.
  • 1.42% for Tanzanian.
  • 1.5% for Arabica.
  • 2.4% for Robusta.

Safe Amounts of Caffeine Intake

Safe amounts of caffeine

Disclaimer - we are coffee fanatics - not doctors. Please consult with a medical professional before going on a wild coffee binge based on the above figures

While it would be almost impossible to set an accurate amount of caffeine that would be safe for absolutely everyone (for all the reasons stated above), there is a consensus for most of the general population, distributed like this:

  • 400mgs or less for healthy adults.
  • 300mgs or less for pregnant women.
  • 0mgs for children from 0 to 4 years old.
  • 2.5mgs or less for every kilogram of body weight for children from 4 to 12 years old.
  • 200mgs or less for people who suffer from arrhythmia, hypertension or type 2 diabetes.

The bottom line is: coffee has way more positive effects on our overall health than negative ones. The evidence gathered can't be argued with and if you get yourself the time to analyze exactly how your body reacts to caffeine, and adhere to the safe amounts recommended (about 4 to 5 cups daily for adults), you will be just fine.

Not only that, you will benefit hugely from it, in the long run, because a regular intake of caffeine WILL improve your overall quality of life.

PRO TIPS

  • Because coffee's boosting effect usually takes about 30 minutes to act, you should take your cup of coffee right before your 26-minute Power Nap (yes, scientists figured out exactly how much you should nap for optimal results). Try it out, and your energy level will go Beast-Mode to help you out on those never-ending office days. Works best with an espresso, or other highly caffeinated coffee types.
  • Do you love the smell of freshly made coffee in the morning, but can't finish one cup without feeling jittery? Try lower caffeine types of coffee, like instant (god forbid) or Ethiopian beans.
  • Time to go to bed but you get a craving for a Cup of Joe? Go decaf. While technically still caffeinated, for a coffee to be considered decaf it must have 97% of its total caffeine removed. Hard to argue with that. And you will still get a good night's sleep.
