Epigallocatechin Gallate, Cerebral Blood Flow Parameters, Cognitive Performance And Mood In Healthy Humans: A Double-blind, Placebo-controlled, Crossover Investigation

この研究の注釈:

A dose of 135mg EGCG, after 45 minutes, resulted in less cerebral blood flow measured in the frontal cortex. A dose of 270mg did not have this effect.

Capsules had 94% EGCG by weight, 6% excipients. Caffeine content not stated but most likely inconsequential due to low dose.

No adverse effects were seen on cognition or mood.
