Caffeine Content in Matcha Green Tea

Matcha is part of a traditional Japanese tradition and has recently becoming quite popular due to its alleged health benefits. Matcha powder is made from ground-up green tea leaves and is a primary ingredient in many drinks and desserts. But how much caffeine is found in a cup of matcha green tea?

Caffeine Content in a Cup of Matcha

It’s difficult to give an exact amount of caffeine in a cup of matcha green tea because the amount of caffeine can vary depending on the quality and origin of the matcha. Generally, a cup of matcha green tea contains between 25-50mg of caffeine per cup. To compare, a cup of coffee usually contains about 95-165mg of caffeine.

Benefits of Caffeine in Matcha

Matcha contains a natural form of caffeine known as “theine” or “teine”. This type of caffeine is said to have a slower effect on the body than caffeine from other sources such as coffee. This means that it gives you a more sustained energy boost that lasts longer than the quick jolt of energy you get from a cup of coffee.

Side Effects of Too Much Caffeine

Although matcha contains less caffeine than coffee, it’s still important to watch your caffeine intake. Too much caffeine can cause:

  • Insomnia: difficulty getting enough sleep or staying asleep.
  • Stress: feelings of anxiety or tension due to long-term excess caffeine consumption.
  • Headaches: caused by caffeine withdrawal or over-consumption.

It’s best to consult with your healthcare provider to make sure you are consuming an appropriate amount of caffeine.


Matcha green tea is a delicious and healthy beverage with less caffeine than a cup of coffee. The caffeine content of matcha can vary depending on the quality and origin of the matcha, but a good estimate is 25-50 mg per cup. As long as you do not over-consume, you can still enjoy the health benefits of matcha green tea without the negative side effects associated with too much caffeine.
