First, let’s think about caffeine in matcha.

The Ministry of Health, Labor and Welfare in Japan recommends that the daily caffeine intake should be below 300 to 400 mg (1 g = 1000 mg) for adults. And, matcha contains about 32 mg of caffeine per gram. One teaspoon of matcha weighs about 1.5 g. Therefore, the caffeine content is about 48 mg, And, it is said that if you take 250 mg or more of caffeine in a day, you can expect the awakening effect.

【250 ÷ 48 = 5.2】If you want to take 250 mg of caffeine from matcha to expect the awaking effect, you should drink matcha with about 5 teaspoons a day. However, you may take caffeine not only from matcha but also from coffee, tea, energy drink and other drinks. Therefore, 2 – 3 teaspoons of matcha is better not to exceed the limit of the day.

In general, matcha served at restaurants is light tea. Therefore, if you drink one cup of matcha, you take 64 mg of caffeine.

Comparing with coffee, one cup of coffee (150 ml dripped with 10 g of coffee beans) contains 60 mg of caffeine. Therefore, the caffeine in one cup of matcha (light matcha) is almost the same as one in a cup of coffee

  1. Can you drink matcha if you’re pregnant?

The Ministry of Health, Labor and Welfare in Japan and overseas recommend that caffeine intake during pregnancy is up to 200-300 mg a day. This is because it takes more time for pregnant women to decrease caffeine in the blood than usual. Therefore, it’s considered that the effects on the body are likely to be stronger than usual.

Studies say that excessive intake of caffeine during pregnancy may be associated with fetal growth inhibition, low birth weight, premature birth or stillbirth. Therefore, if you are pregnant, you need to be aware of taking caffeine.

However, it is believed that there is no major concern as long as you don’t take a lot of caffeine which doesn’t exceed the above range. In the case of matcha, you may drink 4 – 6 cups of matcha a day with a small cup (70 ml).

Please note that the amount of caffeine varies depending on the amount of tea leaves used and the method of dripping, and the sensitivity to caffeine varies depending on individuals.

In particular, since the content of caffeine in matcha is higher than other caffeine drinks, it is better to know how much matcha you take or take a smaller amount than the upper limit as a guide.
