Results

The stress-reducing effect of matcha added to confectioneries is not clear. In animal experiment, the ratio of caffeine and epigallocatechin gallate to theanine and arginine (CE/TA) was a key indicator for the suppression of stress. The result of clinical study showed that matcha with a CE/TA ratio of 2 or less displays a stress-reducing effect, even if it is included in confectionery products.
