Functional Coffee vs Coffee vs Matcha: What’s the Difference?

Coffee vs Functional Coffee vs Matcha: The Short Version

Before getting into the details, here is the simplest comparison.

That final row is particularly important.

A mushroom tincture is not another type of coffee.

It allows you to choose your mushroom extract separately from whatever you happen to be drinking.

That could be coffee.

It could be matcha.

It could be decaf.

Or it could contain no caffeine whatsoever.

What Is Regular Coffee?

Regular coffee begins with roasted coffee beans from plants belonging to the Coffea genus.

Depending on how it is prepared, those beans may be:

• Ground and brewed
• Used for espresso
• Filtered
• Prepared in a cafetière
• Freeze-dried or spray-dried into instant coffee

Coffee naturally contains hundreds of chemical compounds, including caffeine, chlorogenic acids, trigonelline, diterpenes and compounds produced during roasting.[1]

But for most people, one compound dominates the conversation:

Caffeine.

Caffeine stimulates the central nervous system and can increase alertness and reduce sleepiness.[2]

A 2025 systematic review and meta-analysis examining caffeine's acute effects on attention also found an overall improvement in measures of attention following caffeine consumption.[3]

This is why coffee works so well as a morning drink for many people.

But how much caffeine you actually receive can vary considerably.

How Much Caffeine Is in Coffee?

There isn't one universal amount.

Caffeine levels depend on factors including:

• Coffee species
• Bean variety
• Amount of coffee used
• Brewing method
• Extraction time
• Serving size

The European Food Safety Authority gives approximate figures of:

• Espresso, 60 ml: around 80 mg caffeine
• Filter coffee, 200 ml: around 90 mg caffeine[2]

These should be treated as general guides rather than exact values.

Research analysing coffee has repeatedly shown substantial variation between different coffees and preparation methods.[4]

That means two drinks both described as “a coffee” can deliver quite different amounts of caffeine.

What Is Functional Coffee?

This is where the terminology becomes less precise.

There isn't one universal recipe for functional coffee.

In everyday use, the term generally refers to a coffee or coffee-style drink containing additional ingredients beyond conventional coffee.

Those additions might include:

• Functional mushroom powders
• Mushroom extracts
• Botanicals
• MCT oil
• Protein
• Collagen
• Vitamins
• Minerals
• Plant extracts
• Prebiotics
• Other functional ingredients

So rather than thinking of functional coffee as a completely different drink, it is generally more useful to think of it as:

There is an important UK regulatory consideration here too.

Words such as “functional” can imply a health benefit depending on context. In Great Britain, nutrition and health claims made in commercial communications about foods and supplements are regulated, and health claims generally need to comply with the GB Nutrition and Health Claims Register.

For the purposes of this guide, we are using functional coffee simply as a broad descriptive term for coffee products containing additional ingredients.

Does Functional Coffee Still Contain Caffeine?

Usually.

If coffee remains the base ingredient, adding other ingredients does not remove its caffeine.

For example:

• Coffee + Lion's Mane = still caffeinated
• Coffee + Cordyceps = still caffeinated
• Coffee + Reishi = still caffeinated
• Coffee + botanicals = still caffeinated

How much caffeine the finished product contains depends largely on how much coffee is actually present.

Some functional coffee products use less coffee than a conventional cup and may therefore contain less caffeine.

Others use ordinary amounts of coffee.

Some use decaffeinated coffee.

And some products described as functional or mushroom “coffee” do not contain coffee at all.

This is why the ingredient list matters more than the category name.

Where Does Mushroom Coffee Fit In?

Mushroom coffee is best understood as one branch of the wider functional coffee category.

At its simplest, it combines coffee with a mushroom ingredient.

Common examples include:

• Lion's Mane
• Cordyceps
• Reishi
• Chaga
• Multi-mushroom blends

These may be incorporated as mushroom powders or mushroom extracts.

But the phrase “mushroom coffee” tells you surprisingly little about the actual product.

One mushroom coffee might contain mostly ordinary coffee with a small quantity of mushroom powder.

Another may combine instant coffee with concentrated mushroom extracts.

Another might use decaffeinated coffee.

Another may contain chicory or roasted roots and no actual coffee beans at all.

That is why mushroom coffee cannot automatically be described as low-caffeine or caffeine-free.

The mushrooms themselves are not what normally supply the caffeine.

The coffee does.

What Is Matcha?

Matcha sits in a completely different category.

It isn't coffee at all.

Matcha is powdered green tea made from Camellia sinensis, the same plant species used to produce other green and black teas.

Unlike conventional green tea, where the leaves are steeped and then removed, matcha involves finely powdered tea leaves dispersed into the drink.

This creates a distinctive nutritional and chemical profile.

Matcha contains compounds including:

• Caffeine
• L-theanine
• Catechins
• EGCG
• Chlorophyll
• Other polyphenolic compounds[5]

One common misconception, however, is that matcha is a caffeine-free coffee alternative.

It isn't.

Does Matcha Have Caffeine?

Yes.

And potentially a meaningful amount.

Research reviewed in Molecules found matcha samples containing approximately 18.9–44.4 mg of caffeine per gram of powder.[5]

Using 2 grams of matcha at that published range would theoretically provide approximately:

Actual amounts can vary according to the product, cultivar, harvest and preparation.

A more recent analysis of commercially available green teas also found considerable variation in caffeine content between matcha products.[6]

So switching from coffee to matcha does not necessarily mean switching away from caffeine.

Depending on the preparation, their caffeine contents may overlap.

Why Does Matcha Feel Different From Coffee?

You will often hear people describe matcha as providing a “smoother” form of caffeine or claim that it causes no crash.

Those descriptions are subjective and should not be treated as guarantees.

However, matcha does differ chemically from coffee.

One particularly interesting difference is L-theanine.

L-theanine is an amino acid naturally found in tea, and matcha can contain both L-theanine and caffeine.

Research has investigated the two compounds both separately and together.

A systematic review examining caffeine and L-theanine reported evidence that their combination can affect certain measures of attention and cognition.[7]

More recently, a 2026 systematic review and meta-analysis of 31 randomised trials examined L-theanine itself across cognitive and affective outcomes and found some evidence of effects on specific attention measures, while also indicating that its overall clinical relevance remains an area of ongoing study.[8]

This doesn't mean matcha provides “better energy” than coffee.

It means you are consuming a different mixture of naturally occurring compounds.

Some people prefer how they feel after matcha.

Others prefer coffee.

Individual caffeine sensitivity still matters.

Coffee vs Matcha: Which Has More Caffeine?

There isn't a single answer because serving size matters.

As a rough comparison:

Coffee figures are EFSA approximate serving estimates.[2] Matcha estimates are calculated from a published compositional range of 18.9–44.4 mg caffeine per gram.[5]

The important lesson isn't that one always contains more.

It's that:

Matcha contains caffeine too.

If you're deliberately trying to reduce your caffeine intake, simply moving from coffee to matcha may reduce it.

But it might not.

Look at the amount of product being used.

Is Matcha a Coffee Alternative?

Yes, in the sense that it can replace the morning ritual of coffee.

No, if by coffee alternative you mean caffeine-free alternative.

Those are two different things.

Matcha can offer:

• A warm morning drink
• A café-style ritual
• Naturally occurring caffeine
• Naturally occurring L-theanine
• A very different flavour profile from coffee

But someone specifically looking for energy without caffeine would need a genuinely caffeine-free option instead.

Functional Coffee vs Matcha: What Is the Real Difference?

The simplest answer is that they start with completely different plants.

Coffee: Coffea species.

Matcha: Camellia sinensis.

Functional coffee then adds another layer.

Rather than being a specific plant or beverage, it is a product formulation.

Regular Coffee

A caffeinated beverage made from coffee beans.

Matcha

A caffeinated powdered green tea.

Functional Coffee

Coffee or a coffee-style beverage with additional ingredients.

And this is where many of the newer categories begin to overlap.

Mushroom Coffee, Adaptogenic Coffee and Functional Coffee: Are They the Same?

Not exactly.

Think of functional coffee as the broad umbrella.

Under that umbrella you might find several different categories.

Mushroom Coffee

Contains one or more mushroom ingredients.

Adaptogenic Coffee

Contains ingredients marketed within the adaptogen category.

These may include botanical ingredients and sometimes mushrooms.

We'll cover this category in more detail in the next article in this series:

What Is Adaptogenic Coffee? Ingredients, Caffeine and What to Look for Before You Buy

Protein Coffee

Contains added protein.

MCT Coffee

Contains medium-chain triglycerides.

Vitamin or Mineral Coffee

Contains added micronutrients.

And many products combine several categories.

A product could theoretically contain:

It could therefore fit several descriptive categories at once.

That's why category names alone aren't always very useful for comparing products.

The ingredients are.

A Simpler Way to Understand Functional Drinks: Base + Additions

A much easier way to understand the whole category is to divide the drink into two layers.

Layer One: What Is the Base?

For example:

• Coffee
• Decaf coffee
• Matcha
• Green tea
• Chicory
• Roasted roots
• Herbal tea
• Water

This layer usually determines much of the drink's caffeine content and flavour.

Layer Two: What Has Been Added?

For example:

• Lion's Mane
• Reishi
• Cordyceps
• Chaga
• Botanical extracts
• Vitamins
• Protein
• MCT oil

This determines the additional ingredients.

Once you look at drinks this way, the terminology becomes much easier.

Mushroom Latte Made With Matcha

Matcha base + mushroom ingredient

Mushroom Coffee

Coffee base + mushroom ingredient

Caffeine-Free Mushroom Drink

Caffeine-free base + mushroom ingredient

And this brings us to a category that works differently again.

Where Do Mushroom Tinctures and Mushroom Liquid Extracts Fit In?

Mushroom tinctures don't really belong on the same branch as coffee and matcha.

They are a delivery format for the mushroom extract itself.

That difference is important.

With a mushroom coffee, the manufacturer has already chosen the combination:

With a mushroom tincture or mushroom liquid extract, the mushroom is kept separate.

You choose what to do with it.

A liquid mushroom extract can potentially be:

• Taken according to the product instructions
• Added to regular coffee
• Added to decaf coffee
• Added to matcha
• Added to herbal tea
• Added to water
• Added to another caffeine-free drink

This means your choice of functional mushroom no longer dictates your choice of beverage.

Mushroom Coffee vs Mushroom Tinctures

Imagine someone wants to include Lion's Mane in their morning routine.

There are several different ways to do it.

Option 1: Lion's Mane Mushroom Coffee

Coffee and Lion's Mane are already combined.

You consume both together.

If the product contains normal coffee, you also consume caffeine.

Option 2: Lion's Mane Tincture + Regular Coffee

You choose your coffee separately and add your Lion's Mane liquid extract.

Still caffeinated, but you control the coffee and mushroom products independently.

Option 3: Lion's Mane Tincture + Decaf

The same mushroom extract.

Much less caffeine.

Option 4: Lion's Mane Tincture + Matcha

The mushroom format stays the same, but the caffeine now comes from matcha rather than coffee.

Option 5: Lion's Mane Tincture + Caffeine-Free Drink

The mushroom extract remains part of the routine without coffee or matcha.

This is one of the biggest differences between mushroom coffee and mushroom tinctures.

Mushroom coffee makes the mushroom part of the beverage.

A mushroom liquid extract allows the mushroom and beverage to remain separate choices.

Why Does Mushroom Extraction Matter?

If you are comparing functional coffee products, simply seeing the word “mushroom” in the ingredients list doesn't tell you very much.

You may encounter:

• Raw mushroom powder
• Fruiting body powder
• Mycelium
• Mushroom extract powder
• Water extracts
• Alcohol extracts
• Dual extracts
• Liquid extracts
• Tinctures

These are not automatically equivalent.

Mushrooms contain different groups of naturally occurring compounds with different chemical properties.

Water is particularly useful for extracting water-soluble components such as many polysaccharides and beta-glucans.

Alcohol can extract other less water-soluble compounds, including certain triterpenes and sterols.

That is why dual extraction uses both water and alcohol.

Rather than tying the mushroom extract into a pre-formulated coffee product, mushroom tinctures can provide the extracted mushroom separately.

How Mogo Farm Dual Liquid Extracts Are Made

At Mogo Farm, our liquid mushroom extracts are made using a 1:3 dual-extraction process, using mushroom fruiting bodies and both alcohol and purified water.

Our tinctures contain just three core ingredients:

• Mushroom fruiting body
• Alcohol
• Purified water

They are also:

• Caffeine free
• Made without added sugar
• Gluten free
• Suitable for vegans
• Made without grain-based mycelium
• Third-party laboratory tested

Can You Add Mushroom Tinctures to Coffee?

Yes.

A mushroom tincture doesn't need to replace coffee.

It can simply be added to it according to the product instructions.

This is an important distinction because conversations around mushroom supplements and conversations around reducing caffeine often get mixed together.

You may want functional mushrooms and still enjoy coffee.

That's perfectly possible.

You may also want mushrooms while drinking less coffee.

Or no coffee.

The tincture format lets you make those decisions independently.

Can You Add Mushroom Tinctures to Matcha?

Yes.

The two formats don't inherently conflict.

Matcha provides the tea base.

The mushroom tincture provides the mushroom liquid extract.

So someone who prefers matcha to coffee could build a routine around:

rather than buying a mushroom coffee.

It is worth remembering that the matcha itself will still contain caffeine.

Adding a caffeine-free mushroom extract to matcha does not make the resulting drink caffeine-free.

Are Mushroom Tinctures Caffeine-Free?

Mushrooms themselves are not dietary sources of caffeine.

Mogo Farm's mushroom tinctures contain no added coffee, tea, guarana or caffeine.

They consist of:

• Mushroom fruiting body extract
• Alcohol
• Purified water

They can therefore fit into either:

A caffeinated routine, by adding them to coffee or matcha.

Or:

A caffeine-free routine, by taking them separately or with a caffeine-free drink.

This is one reason liquid extracts are particularly flexible.

The mushroom doesn't determine the caffeine level.

Your chosen drink does.

Regular Coffee vs Mushroom Coffee vs Matcha vs Mushroom Tinctures

Putting everything together gives us a clearer comparison.

The biggest difference isn't necessarily which option is “best”.

It's how much control each format gives you.

Which Should You Choose?

There isn't one drink that is automatically superior.

It depends on what you're actually trying to achieve with your routine.

Choose Regular Coffee If...

You enjoy coffee and are comfortable with caffeine.

There is no need to replace ordinary coffee simply because functional beverages have become fashionable.

Coffee itself contains numerous naturally occurring compounds and has been extensively researched.[1,9]

Choose Matcha If...

You prefer tea to coffee and want a naturally caffeinated drink containing the characteristic compounds found in green tea.

Just don't assume that matcha is caffeine-free.

Choose Mushroom Coffee If...

You want the convenience of your coffee and mushroom ingredients already combined into one product.

Check the label carefully to see:

• How much caffeine it contains
• Which mushrooms are present
• Whether they are powders or extracts
• How much of each ingredient is provided

Choose a Mushroom Tincture If...

You want to choose the mushroom separately from your morning beverage.

This can be particularly useful if your routine changes.

Coffee today.

Matcha tomorrow.

Decaf in the afternoon.

No caffeine at all on another day.

The liquid extract remains the same while the beverage changes.

Choose a Caffeine-Free Alternative If...

Reducing or eliminating caffeine is actually your priority.

In that case, neither normal coffee nor matcha is genuinely caffeine-free.

What Should You Look for When Comparing Functional Coffee?

The front of the packet may tell you that something contains mushrooms, adaptogens or “functional ingredients”.

The back of the packet usually tells you much more.

1. What Is the Base?

Coffee?

Decaf?

Matcha?

Chicory?

Something else?

This gives you your first clue about caffeine.

2. How Much Caffeine Is There?

If the manufacturer provides caffeine per serving, that is much more useful than vague phrases such as:

• Reduced caffeine
• Gentle energy
• Morning energy
• Natural energy

If you specifically care about caffeine, look for the number.

3. Which Mushroom Is Included?

“Mushroom blend” is less informative than a clear ingredient list.

Look for the actual species.

4. Is It Mushroom Powder or Mushroom Extract?

These are different preparations.

If it is an extract, look for information about:

• Extraction method
• Concentration
• Mushroom material used
• Serving size

5. How Much Mushroom Are You Actually Getting?

A long ingredient list can look impressive while providing very small quantities of each ingredient.

Transparency matters.

6. What Else Is in the Product?

Check for:

• Added sugar
• Sweeteners
• Flavourings
• Creamers
• Botanicals
• Additional caffeine sources
• Guarana
• Tea extracts

The word mushroom on the front tells you very little about everything else in the cup.

What About Adaptogenic Coffee?

Adaptogenic coffee overlaps significantly with functional and mushroom coffee.

But adaptogen is another term that deserves proper explanation rather than simply being treated as shorthand for “healthy coffee”.

Some adaptogenic coffees contain mushrooms.

Some contain botanicals such as ashwagandha or rhodiola.

Some contain both.

Some contain substantial caffeine.

Others don't contain coffee at all.

We'll look at this properly in the next article in this series:

What Is Adaptogenic Coffee? Ingredients, Caffeine and What to Look for Before You Buy

Is Coffee or Matcha Better for Energy?

This question sounds simple but is actually difficult to answer.

Both contain caffeine.

Caffeine can improve alertness and reduce sleepiness.[2,3]

But the caffeine dose, your own sensitivity, when you drink it and how much you habitually consume all influence how you experience it.

Matcha also contains L-theanine and a different mixture of polyphenols and other compounds from coffee.[5]

Coffee contains chlorogenic acids, trigonelline and numerous compounds produced during roasting.[1]

Neither drink needs to be declared the universal winner.

For some people:

Coffee works better.

For others:

Matcha works better.

And for someone deliberately trying to move away from stimulants:

Neither may be the answer.

That's why it is useful to separate the question of functional ingredients from the question of caffeine.

Can Functional Mushrooms Replace Caffeine?

This is another area where marketing language can become confusing.

Functional mushrooms should not simply be presented as a caffeine substitute.

Caffeine has a well-characterised stimulant action on the central nervous system, primarily involving antagonism of adenosine receptors.

Mushrooms do not work like caffeine.

Research is investigating individual mushroom species in areas including cognition, exercise, fatigue and other physiological outcomes, but the evidence differs significantly between mushrooms, preparations and study populations.

So adding Lion's Mane or Cordyceps to a drink does not turn it into a caffeine equivalent.

And removing caffeine from a drink doesn't mean a mushroom ingredient has somehow replaced its pharmacological effect.

The better way to think about the two is:

That brings us back to why keeping them separate can be useful.

You Don't Have to Choose Between Coffee and Functional Mushrooms

This may be the most important takeaway from the entire comparison.

Functional mushrooms do not require mushroom coffee.

You can enjoy ordinary coffee and take a mushroom liquid extract separately.

You can drink matcha and use a mushroom tincture.

You can switch to decaf and keep the same mushroom routine.

You can remove caffeine altogether without necessarily removing mushrooms.

That makes the decision much simpler.

Instead of asking:

“Should I drink coffee, mushroom coffee or matcha?”

Ask two separate questions.

Question One: How Much Caffeine Do I Actually Want?

Then choose:

• Coffee
• Matcha
• Decaf
• Caffeine-free

Question Two: Do I Want to Incorporate a Functional Mushroom?

If the answer is yes, choose the mushroom format separately.

That could be a mushroom coffee.

But it could also be a concentrated mushroom liquid extract.

Separating those decisions gives you much more control over your routine.

Frequently Asked Questions

Is Functional Coffee the Same as Mushroom Coffee?

Not necessarily.

Mushroom coffee can be considered one type of functional coffee, but functional coffee may contain many other added ingredients including botanicals, MCT oil, protein, vitamins or minerals.

Does Functional Coffee Have Caffeine?

Usually, if ordinary coffee is the base.

However, some products use decaffeinated coffee or coffee-free bases.

Check the ingredients and caffeine declaration.

Does Mushroom Coffee Contain Caffeine?

Most conventional mushroom coffee does because it still contains coffee.

The mushroom itself is not what normally contributes the caffeine.

Read our full guide Does Mushroom Coffee Have Caffeine? for a detailed comparison of regular, low-caffeine, decaf and caffeine-free mushroom drinks.

Does Matcha Have Caffeine?

Yes.

Research has reported considerable variability, with one review identifying approximately 18.9–44.4 mg caffeine per gram of matcha.[5]

Is Matcha Lower in Caffeine Than Coffee?

It can be, but not necessarily.

The amount depends on how much matcha powder is used and how the coffee is prepared.

A strong matcha and a standard coffee can have overlapping caffeine levels.

Is Matcha Caffeine-Free?

No.

Matcha naturally contains caffeine.

Is Mushroom Coffee Caffeine-Free?

Not automatically.

If it contains ordinary coffee, it contains caffeine.

Do Mushroom Tinctures Contain Caffeine?

Mogo Farm mushroom tinctures do not contain caffeine-containing ingredients.

They consist of mushroom fruiting body extract, alcohol and purified water.

Other manufacturers may formulate their products differently, so always check the label.

Can I Put Mushroom Tincture in Coffee?

Yes.

Mushroom liquid extracts can be taken according to their product directions or incorporated into drinks such as coffee.

The resulting drink will still contain whatever caffeine was already present in the coffee.

Can I Put Mushroom Tincture in Matcha?

Yes.

Again, the matcha itself contains caffeine even though the mushroom tincture does not.

Can I Use Mushroom Tinctures Without Coffee?

Yes.

This is one of the main differences between tinctures and mushroom coffee.

A liquid extract can be used independently of coffee and incorporated into a caffeine-free routine if desired.

Is Mushroom Coffee Better Than Regular Coffee?

Neither format is automatically better.

Mushroom coffee provides the convenience of coffee and mushroom ingredients combined.

Regular coffee allows you to enjoy coffee without additional ingredients.

A mushroom liquid extract offers another option: keeping the mushroom separate and choosing your coffee or other drink independently.

Is Matcha Better Than Coffee?

It depends on your preferences and what you want from the drink.

Both contain caffeine, but they have different chemical profiles and flavour characteristics.

Which Option Is Best if I'm Reducing Caffeine?

Start with the actual caffeine content rather than the product category.

Decaf coffee, caffeine-free coffee alternatives and mushroom tinctures used independently of caffeinated drinks provide more control over caffeine intake.

The Bottom Line: Coffee, Matcha and Mushrooms Don't Have to Compete

Regular coffee, functional coffee and matcha are often discussed as though you need to pick a side.

You don't.

They are different drinks serving different purposes.

Regular coffee is coffee.

Matcha is powdered green tea.

Functional coffee is generally coffee or a coffee-style drink with additional ingredients.

Mushroom coffee usually combines a coffee base with one or more mushroom ingredients.

And mushroom tinctures or mushroom liquid extracts allow you to take the mushroom out of that fixed formula altogether.

That last distinction opens up far more choice.

Want coffee?

Add your mushroom extract to coffee.

Prefer matcha?

Use matcha.

Cutting down on caffeine?

Choose decaf.

Avoiding caffeine altogether?

Use a caffeine-free drink.

The mushroom itself doesn't have to determine what is in your cup.

And once you understand that distinction, the increasingly crowded world of functional coffee becomes much easier to navigate.
