According to a 2020 study by the US National Library of Medicine, matcha is rich in antioxidants and vitamins A, C, and K.
Varnit Yadav, a nutritionist in India, says many people consider matcha as an alternative to coffee. Because of its high antioxidant content, matcha can help increase alertness. However, matcha also contains high levels of caffeine, so it should be consumed in moderation.

Like any food, matcha should be consumed based on an understanding of its ingredients, caffeine content, and individual tolerance.
According to Mr. Varnit, matcha should be used in amounts of 2-5 grams per day depending on the body's caffeine tolerance.
Although rich in antioxidants and can improve brain function, matcha can still cause many problems if consumed in excess, according to health site Onlymyhealth (India).
Digestive disorders
Drinking too much matcha or drinking it on an empty stomach can easily cause bloating, flatulence, and acid reflux.
Nausea
The high levels of catechins and caffeine in matcha can irritate the stomach lining, causing discomfort.
Anxiety should not use matcha
People with psychological problems or anxiety disorders should not use matcha because caffeine can increase stress.
Increased heart rate
When using a lot of matcha and coffee, the heart may beat faster, leading to a feeling of restlessness.
Sleep disorders
Caffeine and L-theanine in matcha help increase alertness, but if taken in the late afternoon or in high doses, it can easily lead to sleep disorders.
Consuming more than 5-6 grams of matcha per day may affect your sleep cycle, making it difficult to get deep sleep.
Caffeine accumulation
Matcha contains more caffeine than regular green tea. Exceeding the recommended dose can cause over-stimulation of the nervous system.
In addition, Mr. Varnit also recommends that people with high blood pressure and liver disease should choose the right type of matcha.
Pregnant women can safely consume caffeine (under 200 mg/day), but should also consult a doctor before using matcha.
