I’ve always thought it a bit interesting that the lethal dose of caffeine for most people is about 10 grams, that toxic effects (like seizures) can be observed with consumption of around just 1,200 milligrams of caffeine (which is actually not that much considering that a big ol’ cup of Joe can contain up to 200mg of caffeine), yet, on tons of supplement and bulk foods websites, including Amazon, one can buy one bottle of bulk caffeine capsules that contain enough caffeine to KILL ten people.
Now don’t get me wrong, I’m totally not against caffeine consumption. The stuff can literally be a superfood for the brain, performance, fat loss, and beyond. Heck, I consume caffeine in one form or another just about every day, with just a few slight but notable exceptions, which you’ll read about in this article.
But, as you’ll also learn in this article, caffeine is not something to just casually mess around with while assuming it’s not significantly, and sometimes deleteriously, affecting your neurotransmitters, hormones, and other precious elements of your nervous system (including most of your sleep architecture and circadian rhythmicity) because it just is. That fact can simply not be denied, and knowing how to mitigate risk is something you need to be aware of.
So, what do you do?
Drink coffee for all the health benefits therein, and keep your fingers crossed the caffeine isn’t going to be an issue?
Swear off coffee altogether?
Switch to decaf, but sacrifice flavor and enjoyment due to the bland, stale, chemical-laden nature of most decaf?
In today’s article, you’ll discover the answers to these questions, along with some of the many benefits of coffee (including decaf), how caffeine affects your body and why you should periodically take a break from it, how to identify the cleanest decaf coffee out there, and much more.
Benefits Of Coffee
The benefits of good, high-quality, antioxidant-rich coffee—emphasis on good because there are a lot of mycotoxin- and pesticide-laden coffee beans out there that will do you a lot more harm than good—are well-researched and include:
Despite all of the good things coffee can do for you, as I found out in my twenties, it’s easy to become addicted to, and dependent on, caffeine. Eventually, I couldn’t even function in the morning until I’d sucked down a 20-oz mug o’ Joe…minimum. I’m sure most folks out there could relate, so let’s dive into exactly how coffee and caffeine work in your body, how a caffeine addiction comes to, and how to steer clear of some of the negative effects caffeine can have on your body.
In a nutshell, when I was about 11, my dad decided to get into the coffee business. He bought a vintage Diedrich coffee roaster for the price of a small car and taught himself how to roast coffee, traveled the county hunting down the best beans he could find, and fulfilled his dream of launching a fresh-roasted coffee company with a focus on quality, sustainability, and extreme taste satisfaction.
Fast forward to today, and because of my early exposure to coffee, I’ve tried just about every type of coffee that exists in the health world and beyond—including smart drug-infused coffees, superfood-infused coffee powders, and any variation of coffee you can shake a stick at.
And I’m not alone. Caffeine is America’s—and arguably the world’s—most popular drug, by far.
Whether from coffee, energy drinks, gums, candies, or bars, 90 percent of Americans consume caffeine every single day. More than half of all American adults consume more than 300 milligrams of caffeine every day. Though recommendations by the U.S. Food and Drug Administration (FDA) and the American Medical Association (AMA) are to consider 300 milligrams (around two cups of coffee) the upper limit of a moderate daily dose, roughly 20 to 30 percent of Americans consume more than 600 milligrams on any given day (easy math: around four cups of coffee) every day of the year, backing up the fact that coffee consumption can very likely be categorized as an addiction. If you feel as though you cannot function in the morning without a cup of coffee to kick-start the day, you likely fall into the category of someone who has experienced such addiction, and kicking a caffeine habit can be quite difficult.
So is this amount of caffeine consumption an issue? Considering what you’ve already read in the introduction about the surprisingly low toxicity of coffee, I would argue that it definitely is.
I mean, c’mon folks: It’s a drug.
Caffeine falls into the category of a chemical stimulant scientifically known as trimethylxanthine, with a chemical formula of C8H10N4O2. With this formula, caffeine shares the traits of many “harder” illicit amphetamine-based drugs such as cocaine and heroin, including the ability to cause significant addiction. In its pure form, caffeine is a white crystalline bitter powder used in medical settings to stimulate the heart and serve as a mild diuretic, increasing urine production to flush fluid out of the body.
And just like other drugs, caffeine consumption is not completely devoid of adverse effects. Because it is both water- and fat-soluble, caffeine can easily cross your blood-brain barrier. As you dump more caffeine into your body, your brain cells actually grow an excess of receptors for an inhibitory neurotransmitter called adenosine. Adenosine causes feelings of tiredness and accumulates in your adenosine receptors over the course of the day, but it isn’t the only thing that can bind to your adenosine receptors.
Caffeine, with a structure that closely resembles that of adenosine, also easily fits into your brain’s adenosine receptors. With its receptors constantly plugged up by caffeine, adenosine can no longer bind to them to make you feel tired. Adenosine inhibition also increases the activity of dopamine and glutamate—two feel-good, alertness-increasing, brain-stimulating compounds.
Sounds great, right?
Not so fast. Unfortunately, your body responds to its adenosine receptors being infiltrated by caffeine by creating more and more adenosine receptors, so you eventually need more and more caffeine to block the feelings of tiredness, creating the vicious cycle caffeine addicts are all too familiar with.
See, to a nerve cell, caffeine looks just like adenosine, but caffeine doesn’t slow down cellular activity like adenosine does. As a result, the nerve cell can no longer identify adenosine because caffeine is taking up all the receptors that adenosine would normally bind to. So instead of slowing down, the nerve cells speed up. Make sense?
But because it blocks adenosine’s ability to open vessels, caffeine also causes your brain’s blood vessels to constrict. This is actually why some headache medicines (like Anacin) contain caffeine. The caffeine constricts blood vessels in the brain and that can help to stop a vascular headache.
Caffeine also causes increased neuron firing in your brain. Your pituitary gland senses this activity and releases hormones that tell your adrenal glands to produce adrenaline (AKA epinephrine), a “fight and flight” hormone, which has a number of effects on your body, including:
Increased heart rate
High blood pressure
Low blood flow to the gut
Release of sugar by the liver
This is why, after consuming a cup of coffee, your hands can get cold, your muscles get tense, you feel more excited or jittery, and your heart beats faster.
But adenosine isn’t the only neurotransmitter affected by caffeine. Caffeine also affects dopamine, a neurotransmitter that activates pleasure centers in certain parts of your brain. Heroin and cocaine do the same thing by slowing down the rate of dopamine reabsorption. This dopamine connection contributes heavily to caffeine addiction.
Perhaps the most important potential problem with caffeine is its effect on sleep quality since the half-life of caffeine is about six hours in most people. That means that drinking a cup of coffee containing 200 milligrams of caffeine at 3 pm still leaves around 100 milligrams of caffeine in your system at 9 pm. You’ll be able to fall asleep, but because so much adenosine is blocked, it won’t be high-quality deep sleep. When this cycle continues day after day, a deep sleep deficit accrues. Your body doesn’t heal as readily, nor does learning or memory consolidation occur. This means the sleep you do actually feel like you are getting is not high-quality sleep, creating a vicious cycle in which you crave another cup of caffeinated coffee the next morning.
So ultimately, caffeine blocks adenosine receptors so you feel alert, which significantly impacts sleep quality later in the evening, and it does this whether you are a “fast” or a “slow” caffeine metabolizer. In addition, it injects adrenaline into your bloodstream to give you a boost, while manipulating dopamine production to make you feel good, and also feel addicted.
Then, once caffeine-induced adrenaline wears off, many people experience withdrawal symptoms including headaches, fatigue, and depression, requiring yet another cup of coffee (or energy drink) to get the adrenaline flowing again. This leaves your body in a state of emergency with a lack of focus, jitteriness, and irritability all day long, which isn’t quite a healthy way to go about living every day of the year.
The good news is that it’s fairly simple to kick a caffeine habit and “reset” your adenosine receptors while getting rid of your addiction to the high amounts of dopamine and epinephrine constantly flooding your system.
To do this…
….you only need to get through about 7-12 days of caffeine avoidance…
..which is exactly why I take a week-long break from coffee about once every one to two months—and highly recommend that you do the same.
Yes, you can simply steer clear of all coffee during this week, but since most of the health benefits of coffee having nothing to do with caffeine, you can simply swap your caffeinated coffee for some high-quality, toxin-free decaf coffee during your weeklong caffeine reset. Doing so allows you to also tap into the wonderful aroma, taste, social benefits, and bowel-moving glory of a hot morning beverage…without exhausting your neurotransmitters.
Not All Decaf Coffee Is Created Equal
Now, it’s important to understand that not all decaf coffee is created equally, so if you’re going to use the same strategy I do, you’ll need to proceed with caution.
If you already shop for decaf coffee, you are probably familiar with or have heard of Swiss Water Process (SWP), and seeing this stamped on a coffee label is a good indicator that you’re most likely getting a high-quality decaffeinated product.
Other, more common caffeine-extraction methods that comprise the bulk of the type of decaf you get at most grocery stores and coffeeshops involve the use of heavy, harmful chemicals—one of which, methylene chloride, can also be used as a paint stripper and degreaser (perfect for those who love 3-in-1 deals, but not ideal for those looking for high-quality, longevity-enhancing, flavorful morning brews). Unfortunately, these decaf coffees, although containing less caffeine than their regular counterparts, still contain significant amounts of caffeine. For example, some decaf coffees can have up to 15 milligrams in an 8-ounce cup, which is enough caffeine to disrupt sleep and also keep your adenosine receptors from resetting.
SWP, the Swiss process mentioned above, involves introducing a green coffee extract (GCE) to a mix of water and green coffee beans. Caffeine begins to flow out of the beans until there’s an equal amount of soluble compounds in the GCE and in the coffee beans. Then, water is run through carbon filters to remove the caffeine, and the GCE-rich water is restored and recycled over a 10-hour period until nearly all of the caffeine has been removed from the coffee. So this is both a more natural and more complete form of decaffeinating coffee.
Another process—one that you’re likely less familiar with, but one I’ve been studying up on quite a bit lately—is Mountain Water Processing (MWP). MWP uses—you guessed it—pure mountain water and also removes nearly all of the caffeine. While MWP is nearly identical to SWP in that it maintains the beans’ original components and elements of flavor, I have found that MWP gives you a delicious, aromatic, coffee with almost zero caffeine and a flavor profile that goes above and beyond that of SWP.
When shopping for decaf coffee in the past, I’ve always looked for a high-quality, organic roast that uses SWP to remove caffeine. This has served me well in weeding through the options to wind up with something that more closely resembles coffee in its natural state (and not some Frankencoffee that could double as a paint thinner). Now that I’ve discovered MWP, I’ve got an even better option…
…and, as of very recently, because of everything new I’ve discovered about decaf, I have decided to bring straight to you a new, unique, and incredibly clean decaf coffee.
That’s right: Fresh from our high-end roasters and Kion headquarters in Boulder, Colorado, Kion Decaf Coffee is finally here.
Kion Decaf Coffee—just like its delicious and wickedly popular caffeinated predecessor—uses specialty-grade coffee beans and the absolute highest standards of testing to bring you beans that are 100% organic and free of mold and mycotoxins.
Decaffeinated using the MWP you just learned about, Kion Decaf Coffee offers a clean, pure, “can’t-even-tell-it’s-decaf” taste that’s the result of our using only the top, highest-quality 3% of beans grown worldwide, along with our strict roasting protocol that minimized acrylamide and maximizes antioxidants. Professional cuppers have described Kion Decaf Coffee as…
“Balanced, with a very clean flavor. Medium body, smooth and rich. Sweet apple, marzipan, baking spices. As the cup cools, a nice dark chocolate character emerges.”
Because Kion Decaf Coffee is a medium roast, you can use a variety of brewing methods. It’s great as espresso, French press, or pour-over. (Here’s a handy article that will help you find your perfect brewing method.)
Better yet, you get to switch to decaf every month or two (I personally go through one bag of decaf for every three bags of regular coffee) without sacrificing your flavor or enjoyment.
So to all of my fellow coffee lovers out there: You can now rejoice in knowing that your beloved morning pick-me-up has a hallowed place in promoting total body health.
And with delicious decaf options like Kion Decaf Coffee, you can also now continue enjoying the health benefits (and the taste) of coffee—while giving your adenosine receptors and nervous system a precious break every now and then.
Again, the next time you need a break from caffeine, or if you feel like you’ve been getting too many jitters or need to resensitize yourself to caffeine, just replace your regular brews with Kion Decaf Coffee for a week or so, once per month or once every couple of months.

As an added bonus, below you’ll find two of my favorite coffee recipes—one hot (for those chilly, rainy days) and one cold (for a pre-workout energy boost or a hot day cognitive-enhancing treat):
Prepare yourself for an intense chocolate-sipping experience with a hint of java. Into a blender, combine:
Place all ingredients in blender and purée until smooth, adding water to blend as necessary. Oh, and be careful when you open the lid. This stuff can get a bit…”fizzy.”
This one is a bit more like a milkshake-coffee combo with a bit of a superfood crunch you add in at the end. Into your blender, add the following ingredients:
