Short answer: it depends on the formula, and the mushrooms have nothing to do with it.
That second part surprises people. There's a widespread assumption that mushroom coffee is automatically the lower-caffeine option — that adding functional ingredients somehow dilutes the coffee. It doesn't. The caffeine comes from the coffee base, exactly as it would in any other cup, and how much ends up in your mug is a formulation decision the brand made, not a property of the category.
Mushroom coffee contains anywhere from 0 mg to over 100 mg of caffeine per serving depending on the coffee base used. Bevzilla's range runs 65 mg for Coffee+ Focus, 60 mg for Coffee+ Energy and 1 mg for Coffee+ Calm.
Every one of those numbers is on the pack. That last one is worth explaining, and we'll come back to it.
Mushroom coffee caffeine compared with other drinks
| Drink | Serving | Caffeine |
|---|---|---|
| Bevzilla Coffee+ Focus | 1 sachet, prepared as a standard cup | 65 mg |
| Bevzilla Coffee+ Energy | 1 sachet, prepared as a standard cup | 60 mg |
| Bevzilla Coffee+ Calm | 1 sachet, prepared as a standard cup | 1 mg |
| Brewed coffee | 8 oz | ~96 mg |
| Espresso | 1 oz | ~63 mg |
| Instant coffee | 8 oz | ~62 mg |
| Energy drink | 8 oz | ~79 mg |
| Black tea | 8 oz | ~48 mg |
| Cola | 8 oz | ~33 mg |
Reference values for non-Bevzilla drinks are typical figures published by the FDA and Mayo Clinic, and vary considerably with bean, roast, brewing method and brand. Bevzilla values are from the product label.
One caveat on reading that table: the espresso row is 1 ounce. Our sachets make a full-sized cup. So Focus and a single espresso land at roughly the same caffeine, delivered in wildly different volumes — one is a concentrated shot, the other is a mug you drink over twenty minutes. Same milligrams, different experience.
Where does the caffeine in mushroom coffee come from?
The coffee provides the caffeine. The mushrooms provide the mushroom ingredients. They're separate parts of the formula and one doesn't affect the other.
Our sachets are built on 2 g of instant coffee, which is what puts Focus at 65 mg and Energy at 60 mg. A brand using a heavier coffee load, or espresso, or a different bean, lands somewhere else entirely. That's why two mushroom coffees on the same shelf can be 40 mg apart, and why the word "mushroom" tells you nothing useful about caffeine.
If caffeine is something you track, the only reliable move is reading the milligram figure on the label — and noticing when there isn't one.
Caffeine in each Bevzilla blend
Coffee+ Focus — 65 mg
Roughly a single espresso's worth, in a full cup. Focus pairs its coffee base with Lion's Mane and L-theanine.
Coffee+ Energy — 60 mg
Slightly below Focus, and well under the roughly 96 mg in an average 8 oz brewed coffee. Energy combines the coffee base with Cordyceps and Chaga.
Coffee+ Calm — 1 mg
Calm is built on a decaf base, and this is the number we get asked about most.
We could print 0 mg. Decaffeination removes the overwhelming majority of caffeine but not every last molecule, and 1 mg is small enough that most brands would round it away without thinking twice — it's roughly one-sixty-fifth of what's in Focus, and less than you'd get from a square of dark chocolate.
We print 1 mg because that's what's in it. If the argument is that people deserve accurate numbers on labels, that argument doesn't get suspended when the accurate number is slightly less flattering than the round one. Calm contains Reishi, Shiitake, Ashwagandha and 930 mg of Magnesium Bisglycinate, delivering 210 mg of elemental magnesium — 50% of the Daily Value.

Is mushroom coffee lower in caffeine than regular coffee?
Sometimes, but there's no rule. A mushroom coffee can contain more caffeine than a standard cup, less, or the same — it depends entirely on the coffee base.
An 8 oz brewed coffee averages around 96 mg, though that figure moves a lot with beans and brewing. Our caffeinated blends sit below it at 65 mg and 60 mg. A different brand's mushroom coffee could easily sit above it.
Compare milligrams per serving. Don't infer caffeine from the category name.
Does more caffeine mean stronger coffee?
No. Caffeine content and perceived strength are different things, and they routinely move in opposite directions.
A dark roast tastes bolder than a light one while often containing marginally less caffeine, because roasting burns some off. Espresso tastes intense because it's concentrated into an ounce, not because it holds more caffeine than a mug of drip — it usually holds less in absolute terms. Strength is about extraction, roast and volume. Caffeine is a number.
Which is a long way of saying you can't taste your way to a caffeine estimate. Read the figure.
How much caffeine is safe per day?
The FDA has said that up to 400 mg of caffeine a day is not generally associated with negative effects in healthy adults, though individual sensitivity varies considerably.
That's a ceiling for most people, not a target. Sensitivity varies with genetics, medications, pregnancy and how much sleep you're running on, and caffeine accumulates across everything you drink — coffee, tea, cola, energy drinks, chocolate, some medications. A 65 mg cup looks small on its own and less small as the fourth thing on a list.
If you're managing intake for a specific reason, that's a conversation for a doctor rather than a coffee brand's blog.
Frequently asked questions
Does mushroom coffee have caffeine?
Usually, yes. Most mushroom coffees are made with regular coffee and contain caffeine accordingly. The amount depends on the coffee base, and some products are made with decaf. The mushrooms themselves don't contribute caffeine.
How much caffeine is in mushroom coffee?
There's no standard amount. Bevzilla's range contains 65 mg in Coffee+ Focus, 60 mg in Coffee+ Energy and 1 mg in Coffee+ Calm. Other brands vary widely, from caffeine-free formulas to over 100 mg per serving, so check the specific product's label.
Is mushroom coffee less caffeinated than regular coffee?
Not by default. An 8 oz brewed coffee averages roughly 96 mg, and Bevzilla's caffeinated blends sit below that at 65 mg and 60 mg — but a different mushroom coffee could contain more. The category name doesn't determine the caffeine level.
Does mushroom coffee have more caffeine than espresso?
Roughly comparable, depending on the product. A 1 oz espresso contains about 63 mg. Bevzilla Coffee+ Focus contains 65 mg and Coffee+ Energy contains 60 mg, though those arrive in a full cup rather than a concentrated shot.
Is Coffee+ Calm caffeine-free?
Not quite, and we'd rather say so. It's made on a decaf base and contains 1 mg of caffeine per serving. Decaffeination removes the vast majority of caffeine but not all of it, so we print the actual figure instead of rounding it to zero.
Which Bevzilla mushroom coffee has the most caffeine?
Coffee+ Focus, at 65 mg per serving, followed by Coffee+ Energy at 60 mg. Coffee+ Calm contains 1 mg.
