- 2 in 3 French people feel tired on a daily basis: drinking more and more coffee is not the right answer.
- Matcha provides a "calm energy": steady energy over 4 to 6 hours, without coffee's peak and crash.
- It's the combined action of theine and L-theanine that slows the release of caffeine into the body.
- 1 to 2 g is enough (25-30 mg of caffeine); the ideal is to drink it in late morning and early afternoon.


2 in 3 French people report feeling tired on a daily basis, especially... young people!
Faced with this reality, the temptation to turn to ever-increasing coffee consumption is strong. And yet, this doesn't solve the problem — quite the opposite!
Known for its many benefits and antioxidant content, a Japanese green tea could offer a promising answer: matcha!
The benefits of matcha green tea: a "calm energy" effect
Matcha is a Japanese green tea made from young tea leaves ground into a fine green powder. It is a unique tea because the leaf is fully ingested, making it an excellent source of antioxidants and giving it a very rich content of vitamins and nutrients.
Drinking a cup of matcha tea provides a steady, time-released boost of energy, which we like to call "calm energy". While its relaxing and energizing effect is now confirmed by science, it has been a well-known benefit for over 1000 years among Buddhist monks in Japan, who drank powdered tea to stay awake during their long meditation sessions.
Indeed, thanks to the combined action of theine and L-theanine, matcha promotes concentration and improves mood. It also helps reduce mental fatigue and increase alertness.
Matcha tea vs coffee: longer-lasting energy
This "calm energy" is also characterized by an energy level that lasts over time: about 4 to 6 hours !
That's much longer than coffee, which offers a fairly short energy spike that quickly calls for another cup.
This difference is due to the action of an amino acid, L-theanine. Combined with caffeine (or theine), it slows its release into the body while providing a relaxing effect on the brain.
This is why matcha is said to provide "healthy energy" — a slight misnomer — as it also reduces feelings of stress and anxiety.
Pour aller plus loin : Why Is Drinking Matcha Tea Better for Your Health Than Coffee? Theine and Caffeine →: A cup of coffee contains roughly 100mg of caffeine. In comparison, a bowl of matcha contains 25mg to 30mg of caffeine, which is 3 to 4 times less than a cup of coffee.However, in tea and matcha, this caffeine is called theine, and although it is exactly the same molecule as caffeine, the theine contained in matcha acts differently in our body…
How much matcha should you drink to feel an energizing effect?
From the very first cup!
Rich in caffeine, just 1 to 2 grams of matcha tea is enough to feel a steady, time-released boost of energy. On average, a cup or bowl of matcha contains 2 grams of tea, which means a caffeine content of about 25 to 30mg.
However, be careful not to exceed 3 cups per day for an adult, or 2 cups during pregnancy. Excessive matcha consumption could indeed cause side effects, such as poor iron absorption or difficulty falling asleep.

When should you drink matcha for an anti-fatigue effect? - Avoiding unwanted effects
There are certain times of day to prioritize to make your matcha a true anti-fatigue tea.
The first thing to remember to protect your sleep cycle: you shouldn't consume caffeine as soon as you wake up! While tempting for many of us, it's actually a counterproductive habit. Indeed, upon waking, the body secretes cortisol, which stimulates us and helps us start the day. Consuming caffeine at this time of day is therefore useless. Even worse: caffeine tolerance develops when it is absorbed during the peak of cortisol production — in the end, you no longer feel the much-expected kick from drinking coffee or tea!
Caffeine consumption causes the body to produce more cortisol, which is considered a stress hormone. Hence the possible feelings of anxiety when you consume too much caffeine!
To avoid this problem, it is recommended to start drinking matcha 1 to 3 hours after waking up. This allows time for cortisol production to start decreasing in the body, so you can benefit from a boost of energy.
And for your last bowl of the day, ideally drink it no later than 6 hours before bedtime. A 2013 study published in the Journal of Clinical Sleep Medicine shows that late consumption of caffeinated drinks can have adverse effects on sleep.
In short, to use matcha as an energy-boosting tea, the ideal is to drink it in late morning and early afternoon.
