Coffee & Caffeine: How Much Is Too Much? Can I Overdose?

In discussing the ideas of coffee, caffeine and how much is too much, we need to make a couple major distinctions, questions and definitions.

The most important distinction is are you concerned about coffee consumption or caffeine consumption? Each deserves its own conversation. Then of course there is a third conversation which is about caffeine in coffee and its effects.

How much coffee and caffeine is too much?

health benefits of coffee

Over 400 milligrams/day is too much. Exceeding 400 milligrams of caffeine/day puts you on the high side of the recommended amount considered okay for normal healthy a

dults. Who says so? The FDA and reported by the Mayo Clinic.

It is been clearly demonstrated that drinking coffee on a daily basis in light or moderate amounts is not harmful for almost everybody. In fact, the opposite is been true proven true. There are number of health benefits that are associated with drinking coffee.

The trick is all studies, research, and articles we have seen all make the important qualifier “coffee in moderate amounts”.

So the question becomes what is a moderate amount of coffee on a daily basis. The answer to that is approximately 400 mg of caffeine is considered “safe”. When it comes to coffee, that means 3 or 4 ‘standard’ cups per day. Some care has to be exercised in how we define a ‘standard cup of coffee’. The researchers believe it to be 4 ounces of coffee. I don’t think anyone these days has a cup of coffee that is only 4 ounces.

Did you know?: Standard Starbucks sizes are Short, (8 ounces), Tall (12 ounces), Grande (16 ounces), Venti (20 ounces), and Venti Iced (24 ounces), Starbucks is launching the 31-ounce Trenta.


The smallest Starbucks has 2 ‘standard’ cups of coffee. The Trenti, when it comes out will have 8.

Valuable Lesson Learned: one working as a substance abuse therapist, I remember one client who insisted he only had two drinks per day this did not seem to match up with the bad shape he was in. Upon further prodding I discovered his definition of a “drink” was to fill up a 32 ounce mug half with vodka, half with fruit juice so each drink consistent of a pint of booze. He was drinking a quart a day but to him it was two drinks.

How much caffeine is in my coffee, anyway?

The answer is – it depends. There are many variables.The amount of caffeine found in the coffee beans varies.

On average, a regular cup of coffee contains approximately 90 to 150 mg of caffeine. Coffee brewed in a drip coffee maker has about 115 to 175 mg of caffeine while other coffee makers may brew coffee with about 80 to 135 mg.

Typically, espresso has about as much caffeine as a regular cup of coffee. On average, a standard espresso cup would have about 100 mg of caffeine. However, the serving size for espresso is much smaller.

The actual content of caffeine per milliliter in an espresso is much higher than in a regular brew. Also, caffeine is assimilated quicker when ingested in a concentrated dosage such as an espresso cup.

The amount of caffeine found in coffee blends will also vary. The following are examples of the caffeine content for different coffee blends:

  • Decafs: contains 0.02% caffeine.
  • Brazilian Bourbons: contains 1.20% caffeine.
  • Vienna Roast: contains 1.27% caffeine.
  • Columbia Excelso: contains 1.34% caffeine.
  • Columbia Supremo: contains 1.34% caffeine.
  • French Roast: contains 1.22% caffeine.
  • Costa Rican Tarrazu: contains 1.35% caffeine.

People hypersensitive to the caffeine found in coffee may decide to drink decaffeinated coffee. This way, they can still enjoy the great coffee taste, yet avoid the caffeine. Coffee can be “decaffeinated” by treating the green beans with solvents called chlorinated hydrocarbons.

Once the solvents are removed, the beans are then roasted by ordinary procedures. Most people become accustomed to decaffeinated coffee and do not have to worry about the effects of caffeine..

Let’s take 150 mg per cup as an average. Simply dividing 12,240 milligrams of coffee by 150 mg per cup equals approximately 82 cups of coffee.
