Matcha is a type of green tea that has been enjoyed in Japan for centuries. The tea leaves are grown in the shade, which alters their flavour, colour, and nutritional profile. The leaves are then harvested, steamed, dried, and ground into a fine powder. This powder can be whisked with hot water to create a frothy, vibrant green tea, or used as an ingredient in various recipes.

What is Caffeine?

Caffeine is a natural stimulant that affects the nervous system, increasing alertness and reducing fatigue. It is commonly found in coffee, tea, chocolate, and energy drinks. Caffeine works by blocking the action of adenosine, a neurotransmitter that promotes sleep and suppresses arousal. This leads to an increase in other neurotransmitters, such as dopamine and norepinephrine, which enhance mood, cognitive function, and physical performance.

The amount of caffeine in a food or beverage can vary depending on several factors, such as the type of plant, the processing method, and the serving size. For example, coffee beans contain more caffeine than tea leaves, but a cup of brewed coffee has less caffeine than a cup of brewed tea. Similarly, matcha contains less caffeine than coffee, but more caffeine than regular green tea.

The Caffeine Content of Matcha

Compared to other types of tea, matcha has a higher caffeine content. On average, one teaspoon of matcha contains about 34 mg of caffeine, while a cup of regular green tea has about 25 mg of caffeine. However, the caffeine content can vary depending on the type of matcha, the growing conditions, and the preparation method. For example, ceremonial-grade matcha tends to have a higher caffeine content than culinary-grade matcha due to the younger leaves used in its production.

Factors that can affect the caffeine content of matcha include the amount of tea powder used, the water temperature, and the brewing time. Using more tea powder or hotter water can extract more caffeine from the leaves, while longer brewing times can also increase caffeine content. It’s important to note that while caffeine can provide several health benefits, excessive consumption can have negative side effects, such as insomnia, anxiety, and heart palpitations.

Health Benefits of Caffeine in Matcha

Caffeine in matcha can provide several health benefits when consumed in moderation. One of the most notable benefits is increased energy levels. Caffeine stimulates the central nervous system, which can help reduce fatigue and improve physical performance. It can also enhance mental clarity, focus, and concentration, making it an excellent choice for studying or working.

Additionally, matcha contains an amino acid called L-theanine, which can work in conjunction with caffeine to provide a calm, focused energy boost without the jitters or crash often associated with coffee. This combination can also improve cognitive function, memory, and mood.

Another benefit of caffeine in matcha is its potential to enhance physical performance. Caffeine has been shown to increase endurance and reduce perceived exertion, making it a popular choice among athletes. It can also increase metabolism and promote fat burning, which can aid in weight loss.

Overall, caffeine in matcha can provide several health benefits when consumed in moderation. It’s important to keep in mind that individual tolerance and sensitivity to caffeine can vary, and excessive consumption can have negative side effects. As a general guideline, it’s recommended to consume no more than 400 mg of caffeine per day, which is equivalent to about 12 teaspoons of matcha.

Risks of Consuming Too Much Caffeine

While caffeine has several benefits, it’s essential to consume it in moderation. Consuming too much caffeine can lead to several adverse effects, such as:


Caffeine can interfere with sleep by delaying the onset of sleep, reducing sleep quality, and causing frequent awakenings. This can lead to insomnia, which is associated with several health problems, such as obesity, diabetes, and cardiovascular disease.


Caffeine can increase anxiety by stimulating the release of adrenaline, a hormone that prepares the body for physical activity. This can lead to symptoms such as nervousness, restlessness, and irritability.

Heart Palpitations

Caffeine can cause heart palpitations by increasing the heart rate and blood pressure. This can be especially concerning for individuals with underlying heart conditions or high blood pressure.


In conclusion, matcha is a unique and versatile tea that provides several health benefits due to its high concentration of antioxidants, amino acids, and caffeine. While caffeine can enhance energy, focus, and physical performance, it’s essential to consume it in moderation to avoid adverse effects. To enjoy the benefits of matcha without overdoing it, experts recommend consuming no more than two cups per day.
