What this is
Practical biohacker cognitive drink — delivers the L-theanine + caffeine combo without needing two supplements. Ceremonial-grade matters because heavy metal and pesticide loading is higher in lower-grade culinary matcha. EGCG content is meaningful but lower than concentrated extracts that have caused the rare hepatotoxicity cases.
Mechanism
Whole-leaf shade-grown Camellia sinensis: caffeine (~70 mg per 2 g matcha) + L-theanine (~14-25 mg) + EGCG (~60-100 mg); L-theanine/caffeine combination drives the 'calm focus' acute effect via increased alpha brainwave activity, modulation of GABA/glutamate; EGCG is the dominant polyphenol
Dose & route
1-2 g/day matcha powder (1-2 servings); avoid concentrated catechin extracts for chronic use
