Matcha has become a popular health drink because of its vibrant green color, rich antioxidants, and calming energy boost. Many people drink matcha tea daily for focus, weight balance, and overall wellness. But a common question often comes up: can matcha cause diarrhea?
For some people, the answer is yes. While matcha offers several health benefits, it can also lead to digestive discomfort when consumed incorrectly or in excess.
What Is Matcha?
Matcha is a powdered form of green tea made from specially grown tea leaves. Unlike regular green tea, where leaves are steeped and removed, matcha involves consuming the whole leaf in powdered form.
