Does Mushroom Coffee Have Caffeine? The Honest Answer
Short version: yes, most mushroom coffee has caffeine — but not because of the mushrooms. If you're eyeing mushroom coffee hoping to quietly ditch caffeine, or worried it's a decaf gimmick that won't get you moving in the morning, the real answer sits somewhere in the middle. Let's clear it up honestly, because the marketing around this drink tends to muddy a pretty simple question.
Where the caffeine actually comes from
Mushrooms don't contain caffeine. Not lion's mane, not cordyceps, not chaga — none of them. So when a mushroom coffee has caffeine (and most do), it isn't coming from the fungi. It's coming from the actual coffee blended in.
That's the part a lot of shoppers miss. "Mushroom coffee" is a bit of a misnomer — it's usually real coffee plus mushroom extracts, not coffee brewed out of mushrooms. The caffeine content therefore depends entirely on how much real coffee is in the blend. A product built on genuine coffee beans will have a meaningful amount of caffeine. A product that leans hard on fillers and uses very little actual coffee will have very little.
This is exactly why "does mushroom coffee have caffeine?" doesn't have one universal answer. It depends on the brand, and specifically on whether that brand uses real coffee or treats the coffee as an afterthought.
How much caffeine is in mushroom coffee?
Here's the honest range. A standard 8-ounce cup of brewed coffee lands around 95 mg of caffeine. Most mushroom coffees come in noticeably lower — commonly somewhere in the neighborhood of 40 to 75 mg per serving, though it varies widely by brand and serving size.
Why the dip? In many blends, the mushroom powder essentially takes the place of some of the coffee. If half the scoop is mushroom extract, you're getting roughly half the coffee — and therefore less caffeine — than you would from a straight cup. That's the trade some brands make on purpose, marketing the lower caffeine as a feature.
We'll be straight with you about Kaizen: the Signature Mushroom Coffee Blend is built on organic instant arabica coffee as its very first ingredient, so it genuinely contains caffeine — this is real coffee, not a caffeine-free substitute. There's also a small additional contribution from the organic cacao in the blend, since cacao naturally carries a little caffeine (and its cousin theobromine). This combination comes out to about 90mg of caffeine, very close to a real cup of coffee. The reason for most jitters and anxiety isn't actually the caffeine, it's the mold & mycotoxins that wreak havoc on your nervous system.
Why mushroom coffee often feels smoother than the caffeine number suggests
This is where it gets interesting, and where the honest story is better than the hype. Two things shape how caffeine feels, not just how much you drink.
First, the total dose. A slightly lower caffeine load can mean a gentler on-ramp and a softer landing — fewer people report the mid-morning spike-and-crash when the dose isn't sky-high.
Second, and more importantly, what the caffeine is paired with. Kaizen Coffee includes L-theanine, an amino acid found naturally in tea leaves. There's a well-documented pairing effect here: L-theanine appears to take the sharp edges off caffeine — the jitters, the racing feeling, the anxious buzz — while keeping the alertness intact. Research on the theanine-and-caffeine combination points toward calmer, more focused energy rather than a wired one. It's associated with a "relaxed alertness" state, which is a big part of why a well-formulated mushroom coffee can feel steadier than a triple-shot americano even when both contain caffeine.
On top of that, the blend leans on cordyceps, a mushroom traditionally used for stamina and studied for its role in cellular energy production. Cordyceps doesn't add caffeine — it's not a stimulant — so any lift it contributes is separate from your caffeine dose. The idea behind the formula is that your energy isn't riding on caffeine alone.
So the honest framing is this: mushroom coffee usually isn't magic, and it isn't caffeine-free. But a thoughtfully built one can deliver caffeine that feels smoother, thanks to a lower-and-buffered dose rather than any mushroom sorcery.
Is mushroom coffee a good choice if you're cutting back on caffeine?
It can be — with a caveat. If your goal is less caffeine but not none, a real-coffee mushroom blend is a reasonable step down from a large drip coffee, especially paired with L-theanine to smooth the experience. Many people find they're comfortable drinking it a little later in the day than they would a full-strength cup.
But if you need to be genuinely caffeine-free — say, for pregnancy, certain medications, or a medical reason — mushroom coffee made with real coffee is not the answer. It still has caffeine. In that case you'd want a caffeine-free functional beverage or a mushroom blend explicitly labeled caffeine-free, and it's worth checking with your doctor. We'd rather lose a sale than have someone assume "mushroom" means "no caffeine." It doesn't.
What to look for on the label
If caffeine content matters to you, don't judge a mushroom coffee by the picture of mushrooms on the front. Read the ingredient list. The order tells you a lot: if real coffee (or organic instant arabica) sits at or near the top, you're getting genuine coffee and genuine caffeine. If coffee is buried near the bottom behind a stack of fillers, expect a much weaker cup. Look, too, for supporting ingredients like L-theanine that shape how the caffeine actually feels, and for third-party testing that verifies what's in the bag is clean — Kaizen Coffee is batch-tested for mold, mycotoxins, glyphosate, and heavy metals, which matters more with coffee than most people realize.
Frequently asked questions
Does mushroom coffee have caffeine?
Yes, almost always. The caffeine comes from the real coffee in the blend, not from the mushrooms, which are naturally caffeine-free. The exact amount depends on how much actual coffee the product contains.
How much caffeine is in mushroom coffee?
It varies by brand, but many land around 40 to 75 mg per serving, versus roughly 95 mg in a standard cup of brewed coffee. Blends built on real coffee sit toward the higher, more coffee-like end; filler-heavy blends sit lower.
Does Kaizen mushroom coffee have caffeine?
Yes. Its first ingredient is organic instant arabica coffee, with a small additional amount from organic cacao. We don't publish an exact milligram figure, but it's real coffee and it contains caffeine.
Will mushroom coffee give me the jitters?
It can if you're sensitive, since it still contains caffeine — but many people find it feels smoother. Kaizen Coffee includes L-theanine, which is associated with taking the edge off caffeine's jittery side while keeping you alert.
Can I drink mushroom coffee if I'm avoiding caffeine completely?
Not if it's made with real coffee. If you need zero caffeine, choose a product explicitly labeled caffeine-free and, when in doubt, check with your healthcare provider.
The bottom line
Mushroom coffee has caffeine — the mushrooms don't, but the coffee does. The real differences between products come down to how much genuine coffee is in the blend and what that caffeine is paired with. Kaizen's Signature Mushroom Coffee Blend is built on real organic arabica for a cup that still performs like coffee, then rounds it out with L-theanine and functional mushrooms so the energy tends to feel calmer and more sustained. No decaf sleight of hand, no pretending it's caffeine-free — just a more thoughtfully built cup.
