It is advisable to brew 2 cups of matcha powder every day. Studies have shown that drinking 2 cups of Matcha A every day can protect cells and tissues from free radical damage, reduce the risk of cardiovascular disease, improve mood, memory and attention, and reduce age-related cognitive decline. In addition, matcha is rich in theanine, which will not affect sleep after drinking. Matcha is a kind of green tea powder, but its health care effect is far better than ordinary green tea. Studies have pointed out that the concentration of catechin (EGCG) in matcha is 137 times that of ordinary green tea and 3 times that of high-grade green tea. In addition, the chlorophyll and theanine in matcha are much higher than those in ordinary green tea.
