Green Tea Catechin Dose Evidence
Green tea catechin dose evidence: cups beat reckless EGCG extracts—steeped greens and measured matcha stay in food ranges; pills risk liver harm.
Green tea catechin dose evidence maps cups to EGCG—typical brewed green tea delivers tens to low hundreds of milligrams EGCG per day when you drink two to four cups, while extract pills often exceed safe upper intake and stress liver in case reports. Steep two to three minutes in sub-boiling water to limit bitterness without chasing zero polyphenols.
Matcha ingests whole leaf so milligrams rise per gram powder. Sleep and caffeine caps still apply.
Common questions
-
How many green tea cups equal study EGCG doses?
Studies vary—roughly two to four brewed cups cover many food-range intakes. Extract megadoses exceed what cups provide and add liver risk; prefer tea with clinician input.
