Does Mushroom Coffee Have Caffeine? Milligrams by Product Type
In one line
Mushroom coffee does have caffeine in most cases — typically 30–60 mg per serving for instant blends and 80–100 mg for ground blends, versus about 95 mg in an 8 oz brewed coffee — while decaf versions and mushroom coffee alternatives range from 0 to about 35 mg, and the mushrooms themselves contribute none.

Caffeine by product type
| Product type | Typical caffeine per serving | What's in the cup |
|---|---|---|
| Instant mushroom coffee blend | 30–60 mg | Instant arabica plus mushroom extracts, sometimes MCT, collagen or L-theanine |
| Ground or whole-bean mushroom coffee | About 80–100 mg | Roasted beans with extract mixed in; brewed like normal coffee |
| Decaf mushroom coffee | Trace (under about 5 mg) | Decaffeinated beans plus extracts |
| Mushroom coffee alternative | 0–35 mg | Cacao, chicory, roasted grains or tea plus extracts; no coffee |
| Regular brewed coffee, 8 oz | About 95 mg (95–200 mg range) | Coffee |
The brewed-coffee figure comes from Harvard's Nutrition Source; MedlinePlus gives a wider 95–200 mg range because strength and cup size vary. The mushroom coffee figures are the ranges we see on labels and in brand disclosures across our reviews. Where a brand discloses a number we list it on its review page.
Why instant blends have about half a cup's worth
The mushrooms contribute no caffeine. The difference is simply how much coffee is in the scoop. A typical instant serving is 5–8 g of powder, and a large share of that is mushroom extract, cacao, MCT or other add-ins. What's left is a few grams of instant coffee, and instant coffee at that dose lands at roughly 30–60 mg. Ground mushroom coffees put extract into a normal dose of beans, so they brew like normal coffee and carry normal caffeine.
Some brands frame the lower number as a feature ("no jitters"), and for caffeine-sensitive people it genuinely is. It also means two servings of an instant blend equal about one strong regular cup, which matters if you are counting toward the 400 mg a day that MedlinePlus cites as the level most healthy adults tolerate.
L-theanine changes the feel, not the number
A few blends add L-theanine, the amino acid found in green tea. Memorial Sloan Kettering's summary notes that theanine and caffeine have interacting effects on mood and cognition, and many drinkers describe the combination as smoother. It does not reduce the caffeine content, so a label that promises "calm energy" from L-theanine should still show a caffeine figure.
How to read caffeine on a label
- Look for an explicit milligram figure per serving. Good brands print one; vague phrases like "half the caffeine of coffee" are a yellow flag.
- Check the serving size. A 6 g scoop and a 10 g scoop from two brands are not comparable per scoop, only per serving.
- Read the base ingredient. "Instant coffee" means 30–60 mg territory; "ground coffee" means a full cup; "cacao" or "chicory" means an alternative.
- Decaf still has trace caffeine. U.S. rules require at least 97% removal, so a decaf serving carries a few milligrams.

Frequently asked questions
Does mushroom coffee have caffeine?
Yes, unless the label says decaf or the product is a coffee alternative. Most instant mushroom coffees contain 30–60 mg of caffeine per serving, roughly half of an 8 oz brewed cup. Ground mushroom coffees, which are mostly real coffee beans, land near a normal cup at around 80–100 mg. Mushrooms themselves contribute no caffeine.
How much caffeine is in mushroom coffee compared to regular coffee?
An 8 oz cup of brewed coffee has about 95 mg of caffeine according to Harvard's Nutrition Source, with MedlinePlus giving a 95–200 mg range depending on strength. A typical instant mushroom coffee serving has 30–60 mg, so one mushroom coffee is roughly half a regular cup. Two servings equal about one strong coffee.
Is there caffeine-free mushroom coffee?
Yes, in two forms. Decaf mushroom coffee uses decaffeinated beans, so it carries trace caffeine like any decaf. Coffee alternatives replace coffee entirely with cacao, chicory, roasted grains or tea plus mushrooms; these range from zero caffeine to about 35 mg when they include cacao or black tea. Check the label, because coffee-free does not always mean caffeine-free.
Why does mushroom coffee have less caffeine than regular coffee?
Because a scoop contains less coffee. An instant blend serving is usually 5–8 g of powder, and a third or more of that is mushroom extract and other add-ins, leaving a few grams of instant coffee. A regular cup uses roughly 10 g of ground beans. Some brands also add L-theanine, which does not lower caffeine but may soften its edge.
