Does matcha tea contain caffeine?

Matcha tea does contain caffeine. Unlike coffee, its caffeine, called theine, is released gradually thanks to L-theanine. The result? Gentle, sustained energy (4 to 6 hours) without palpitations or a "crash." In this article, discover how this ancient ritual offers a healthy alternative to coffee, while boosting concentration and well-being thanks to its exceptional synergy of active molecules.

Matcha tea, a naturally caffeinated beverage

Matcha tea contains caffeine, also known as "theine," an identical molecule (1,3,7-trimethylxanthine) that stimulates the nervous system and reduces fatigue. A 1-gram serving of matcha powder provides approximately 48 mg of caffeine, which is less than coffee (90 mg per 150 ml cup) but more than most brewed teas.

Unlike other teas, matcha is consumed by consuming the entire ground leaf, which concentrates its nutrients, including caffeine. The presence of L-theanine (an amino acid) slows down caffeine absorption, providing a gentle and sustained energy (4 to 6 hours), without the side effects of coffee like the "crash" we all know.

L-theanine also promotes a state of calm focus by activating alpha brain waves, ideal for wellness enthusiasts. This synergy between caffeine and natural compounds makes it a unique stimulant . To learn more about its benefits, discover what matcha is .

What is the caffeine content of matcha compared to coffee?

Matcha tea contains between 45 and 70 mg of caffeine per cup prepared with 1 to 2 grams of powder. By comparison, a cup of filter coffee typically contains 80 to 100 mg of caffeine. However, these figures vary depending on the quality of the product and the preparation method.

While matcha contains less caffeine than coffee, its effect is modulated by L-theanine. This synergy allows for a gradual release of energy over 4 to 6 hours, compared to approximately 3 hours for coffee. This unique characteristic makes matcha particularly well-suited for maintaining concentration and alertness without causing an energy crash.

Studies show that the caffeine in matcha is metabolized differently thanks to catechins, antioxidants that slow its absorption. This mechanism reduces side effects such as palpitations or anxiety often associated with coffee. Nevertheless, people sensitive to caffeine should moderate their consumption, especially in the evening.

The unique effect of caffeine in matcha: stable energy without jitters.

Unlike coffee, which causes an energy spike followed by a crash, matcha provides a gentle and sustained energy thanks to the synergy between caffeine and L-theanine.

The synergy of caffeine and L-theanine

Matcha contains L-theanine, an amino acid that promotes the production of alpha waves in the brain. These waves are associated with a state of calm concentration, similar to that experienced during meditation. L-theanine modulates the stimulating effects of caffeine, mitigating the risk of restlessness or anxiety. This combination improves alertness and concentration , without the side effects frequently associated with coffee.

Slow release for sustained energy

The caffeine in matcha is bound to catechins, antioxidants that slow its absorption. As a result, the energizing effect lasts between 4 and 6 hours, compared to 2 to 3 hours for coffee. This slow release avoids the energy spikes and crashes typical of coffee.

• Energy type: stable and diffuse for matcha; intense peak for coffee.
• Duration of effects: 4 to 6 hours for matcha; 2 to 3 hours for coffee.
• Side effects: little nervousness with matcha.
• Impact on concentration: calm and sustained concentration.

Factors that influence the caffeine content of your matcha

The quality of matcha

Ceremonial matcha, like ours, comes from young, shade-grown leaves. This method promotes a high caffeine content (60-80 mg/2g) and L-theanine , an amino acid that softens its stimulating effects. Culinary grades, made from mature leaves, contain 30-45 mg/2g and have a more bitter taste.

The preparation method

The amount of powder determines the caffeine dose: doubling the portion (e.g., 2 g) doubles the intake. Although water temperature influences extraction, consuming all the powder ensures complete caffeine absorption, even with cold water .

Our tips for consuming your matcha

What time of day is best to drink matcha?

Matcha is ideal upon waking or before intellectual or physical activity. To preserve sleep, avoid consuming it after 5 or 6 pm, depending on your sensitivity.

How much and what precautions?

One to two cups a day (1 to 2 g of powder) is enough to enjoy the benefits of matcha. For tailored recommendations, consult our guide on the recommended daily amount . Pregnant or breastfeeding women should consult a doctor, as the maximum recommended dose varies between 200 mg (UK Agency) and 300 mg (WHO) of caffeine per day.

To avoid side effects (insomnia, nervousness), adjust your consumption to your sensitivity . People prone to digestive problems may prefer less concentrated teas like hojicha, as matcha contains tannins that can irritate the stomach on an empty stomach. In the evening, opt for caffeine-free alternatives: rooibos, herbal teas, or mint infusion.

Matcha: much more than just a source of caffeine

Matcha offers a healthy alternative to coffee. Its antioxidants and L-theanine (supported by studies from Shizuoka University) promote a balance between vitality and calmness .
