Caffeine deserves a clear warning.

Matcha contains caffeine.

That may be part of why many people enjoy it as a morning or afternoon beverage—but it is also something consumers should understand clearly.

Matcha is not caffeine-free

Matcha is made from powdered tea leaves, and tea naturally contains caffeine.

The amount of caffeine in a serving can vary depending on factors such as the amount of powder used, the tea material, cultivation and preparation.

This means there isn’t one universal caffeine number for every matcha.

Scientific studies have reported substantial variation in the caffeine content of matcha samples.

Matcha vs coffee

You will often see brands claim that matcha contains “less caffeine than coffee.”

That can be misleading without specifying the serving.

A cup of coffee and a bowl of matcha may use different serving sizes, preparation methods and caffeine concentrations.

The useful comparison is: how much caffeine is in the actual serving you consume? Not simply: which beverage has more caffeine?

Why does matcha feel different?

Matcha contains both caffeine and L-theanine.

Research has investigated the combination of caffeine and L-theanine in relation to attention and cognitive performance. A recent systematic review found some evidence of short-term benefits, while also emphasising uncertainty and the need for further research.

That does not mean everyone will experience the same effect. Individual responses to caffeine vary.

When should you drink matcha?

For many people, morning or early afternoon is a practical time.

If caffeine affects your sleep, avoid drinking matcha close to bedtime.

The amount of caffeine you consume throughout the entire day also matters—not just the matcha.

Remember that caffeine can come from:

• Coffee
• Tea
• Matcha
• Energy drinks
• Cola
• Pre-workout products
• Chocolate
• Certain medications and supplements

Who should be especially careful?

People who are sensitive to caffeine may experience:

• Difficulty sleeping
• Restlessness
• Jitters
• Increased heart rate
• Headaches
• Anxiety or nervousness

If you are pregnant, breastfeeding, taking medication, have a condition affected by caffeine, or have been advised to limit caffeine, speak with a qualified healthcare professional about your individual intake.

How much matcha should you use?

For a typical preparation, many people start with around 1–2g of matcha.

That doesn’t mean every 1–2g serving contains the same amount of caffeine. The actual caffeine content depends on the tea.

That’s why brands should avoid presenting a universal caffeine number unless they have tested the specific product or have reliable product-specific documentation.

The simple takeaway

Matcha can be a useful caffeinated beverage.

But “natural” doesn’t mean “caffeine-free.” And “matcha” doesn’t automatically mean a fixed caffeine amount.

Know your serving. Know your sensitivity. And know what’s in your cup.
