Matcha Nutrition Facts & Calories: What’s Actually in a Serving?
A practical look at calories, carbohydrates, sugar, caffeine, L-theanine and catechins in pure matcha—and why a matcha latte can have a very different nutrition profile.
Pure matcha is a finely ground green tea powder. Because the powder itself is consumed, matcha is different from ordinary brewed tea, where the tea leaves are removed after steeping.
A typical matcha serving is small—often around 2 grams—so plain matcha contributes very few calories. The ingredients that most dramatically change a matcha drink's calories are usually milk, sweetener, syrups, cream and toppings rather than the matcha itself.
Nutrition values vary by product, harvest and laboratory method. This guide therefore uses practical ranges and published examples rather than presenting one brand's numbers as universal facts.
Matcha nutrition facts at a glance
Multiple unsweetened matcha product labels list about 5 calories per 2-gram serving.
100% matcha contains no added sugar. Sweetened matcha mixes are a different product.
Published research has reported roughly 18.9–44.4 mg caffeine per gram of matcha, although actual products vary.
Matcha naturally contains catechins and L-theanine, but these are not usually listed in a standard Nutrition Facts panel.
If a café matcha latte contains substantial calories or sugar, look at the milk, sweetener, syrup and toppings before blaming the few grams of pure matcha.
How many calories are in matcha?
Unsweetened pure matcha is very low in calories. Several commercial nutrition labels for 100% matcha list approximately 5 calories per 2 grams.
Exact label values can differ because the serving is tiny and nutrition labeling rules involve rounding. For that reason, the numbers below are best used as practical estimates rather than laboratory values for every matcha.
| Pure matcha amount | Approximate calories | Typical use |
|---|---|---|
| 1 g | About 2–3 calories | Light serving |
| 2 g | About 5 calories | Common usucha / everyday serving |
| 3 g | About 7–8 calories | Stronger latte-style serving |
| 4 g | About 10 calories | Strong or thick preparation |
Traditional Japanese tea maker Ippodo uses 2 grams for a standard usucha preparation and commonly uses 3 grams for lattes and 4 grams for koicha in its recipes.
Typical nutrition facts for 2 grams of pure matcha
Product labels vary, but 2-gram servings of unsweetened matcha commonly fall around the following values:
| Nutrient | Typical label value for ~2 g | What it means |
|---|---|---|
| Calories | About 5 kcal | Very small contribution to total daily calories |
| Total fat | Usually 0 g on the label | Trace amounts may round to zero |
| Carbohydrate | About 0–1 g | Varies by product and label rounding |
| Dietary fibre | About 0–1 g | Small serving means matcha is not a major fibre source |
| Total sugar | Usually 0 g | Pure matcha has no added sugar |
| Protein | About 0–1 g | Not a meaningful protein source at normal serving sizes |
| Sodium | Usually 0 mg or negligible | Varies by label and rounding |
If you need exact nutrition values for a particular Blendit product, use that product's laboratory analysis or official package label. Matcha is an agricultural product and composition can vary.
How much caffeine is in matcha?
Matcha naturally contains caffeine. A scientific review reported matcha caffeine concentrations of approximately 18.9–44.4 mg per gram. At a 2-gram serving, that broad research range would correspond to roughly 38–89 mg of caffeine.
This does not mean every 2-gram matcha contains the same caffeine amount. Cultivar, leaf age, growing conditions, harvest and the individual matcha all influence composition.
| Matcha powder | Approximate caffeine using published 18.9–44.4 mg/g range |
|---|---|
| 1 g | About 19–44 mg |
| 2 g | About 38–89 mg |
| 3 g | About 57–133 mg |
The FDA cites 400 mg of caffeine per day as an amount not generally associated with negative effects for most healthy adults, but individual sensitivity varies and this is not a recommended daily target.

Does matcha contain L-theanine?
Yes. L-theanine is an amino acid naturally found in tea. Shade-growing, which is part of traditional matcha production, helps preserve amino acids in the leaves.
Published matcha analyses show that L-theanine content can vary substantially. A 2026 scientific review summarized one analyzed approximately 2-gram matcha portion containing about 50.3 mg of L-theanine. That should be viewed as an example, not a guaranteed amount for every product.
Standard Nutrition Facts panels focus on required nutrients such as calories, fat, carbohydrate, sugars and protein. Naturally occurring L-theanine is not usually declared unless a producer specifically tests and chooses to provide it.
What about antioxidants, catechins and EGCG?
Matcha naturally contains tea polyphenols known as catechins, including epigallocatechin gallate (EGCG). These compounds are one reason matcha is frequently studied in nutrition research.
A recent review summarized one approximately 2-gram matcha portion containing about 170 mg total catechins, including around 109.8 mg EGCG. Again, these values come from a published analysis and should not be treated as the guaranteed composition of every matcha.
The presence of catechins does not mean a cup of matcha prevents, treats or cures disease. Matcha is a tea and food ingredient, not a medication.
Does matcha contain sugar or carbohydrates?
Pure 100% matcha contains no added sugar. Many 2-gram product labels list 0 grams of total sugar and around 0–1 gram of total carbohydrate.
The confusion usually comes from products called “matcha” that are actually pre-sweetened latte mixes or café drinks.
| Product | Sugar situation |
|---|---|
| 100% pure matcha powder | No added sugar |
| Matcha + water | No added sugar unless you add it |
| Matcha latte | Depends on milk and sweetener |
| Sweetened matcha powder | Can contain significant added sugar |
| Café flavoured matcha drink | Depends on syrups, sauces, sweetened milk and toppings |
When buying matcha, check the ingredient list. If you want pure matcha, the ingredient list should simply identify matcha / green tea powder rather than sugar as a major ingredient.
How many calories are in a matcha latte?
The matcha itself usually contributes only a few calories. Most of a matcha latte's calories come from the milk and any sweetener.
| Drink component | Effect on calories |
|---|---|
| 2 g pure matcha | About 5 calories |
| Water | No meaningful calories |
| Dairy or plant milk | Can become the main calorie source |
| Honey, sugar or syrup | Adds carbohydrates, sugar and calories |
| Cream, cold foam or toppings | Can increase calories substantially |
A simple way to calculate your matcha latte
Add the calories from your measured matcha serving to the calories on the milk label for the amount you actually use, then add any sweetener or topping.
If your matcha contributes about 5 calories, almost the entire difference between a light matcha latte and a high-calorie café drink comes from what is added to those 2 grams of matcha.
Does ceremonial matcha have fewer calories than culinary matcha?
Not in a way that normally matters nutritionally. Both are powdered green tea, and their calorie contribution at a 1–2 gram serving is very small.
The more important differences are usually taste, aroma, colour, harvest, leaf selection, processing and intended use. Also remember that “ceremonial grade” is not a globally standardized legal nutrition grade.
Usually selected for smoother flavour, aroma, umami and drinking straight or in high-quality lattes.
Usually chosen for recipes where a stronger tea flavour must remain noticeable among other ingredients.

Does organic matcha have different nutrition?
Organic certification describes how the tea was produced and certified; it does not automatically mean the matcha contains fewer calories or a guaranteed higher level of caffeine, catechins or L-theanine.
If organic sourcing matters to you, choose it for the certification and agricultural standards rather than assuming the word “organic” guarantees a particular nutrient profile.

Choose matcha for quality—not because it is “zero calorie”
Pure matcha is naturally very low in calories. Focus on origin, freshness, flavour and the ingredients you add to your drink.
Matcha nutrition FAQs
How many calories are in 1 teaspoon of matcha?
A level teaspoon is often around 2 grams, though measuring spoons vary. Many pure matcha labels list about 5 calories per 2-gram serving.
How many calories are in 2 grams of matcha?
Around 5 calories is common on commercial nutrition labels for unsweetened 100% matcha, although exact values can vary.
Does pure matcha have sugar?
Pure 100% matcha has no added sugar and many nutrition labels show 0 grams of total sugar at a normal 2-gram serving.
Does matcha have carbohydrates?
In a typical 2-gram serving, commercial labels commonly show around 0–1 gram of carbohydrate. Some of that may be dietary fibre.
Does matcha have protein?
Matcha contains very small amounts of protein, but a normal serving is too small for matcha to be considered a meaningful protein source.
How much caffeine is in 2 grams of matcha?
Using a published matcha range of 18.9–44.4 mg caffeine per gram, a 2-gram serving could contain roughly 38–89 mg. Individual products vary.
Does matcha contain L-theanine?
Yes. Matcha naturally contains L-theanine, but the amount varies and is not normally shown on standard nutrition labels.
Is a matcha latte low in calories?
It can be, but the final calorie count depends mainly on the type and amount of milk, sweetener, syrup and toppings rather than the matcha powder itself.
Is sweetened matcha the same nutritionally as pure matcha?
No. A matcha mix containing sugar or other ingredients can have a very different calorie and carbohydrate profile from 100% pure matcha.
Final thoughts
Pure matcha contributes very few calories at a normal serving size. Instead of focusing only on calories, it is more useful to understand the difference between pure matcha and a prepared matcha drink.
A bowl of matcha with water may contain only around 5 calories from a 2-gram serving, while a latte or smoothie can contain much more depending on milk, fruit, sweetener and other ingredients.
For exact nutrition information about any specific packaged matcha, use the nutrition label or laboratory analysis for that exact product.
