My quick answer would be no, it is not. Matcha has many great health and other benefits, but none of the disadvantages of coffee.
Organic Matcha has all kinds of health advantages, and is simple to add to your diet. If you want to drink the finest Matcha, you will need to verify that you are buying Organic and Ceremonial grade.
“Matcha contains a wealth of antioxidants, amino acids, chlorophyll, and other vitamins and nutrients. With normal teas, you only consume the nutritional benefits that are steeped outside into the water. With matcha though, you consume the full leaf, and thus the full nutritional benefits, in only a few sips. Specifically, matcha enhances antioxidant activity, supports metabolism and promotes energy and alertness.” – Forbes.
