What the evidence says about Green tea extract

NCCIH says green tea catechins plus caffeine may have a modest effect on body weight and modestly lower total and LDL cholesterol, with inconsistent results for cancer and heart disease. The safety arm of the Minnesota Green Tea Trial, which gave 1,315 mg catechins (843 mg EGCG) daily for 12 months to 1,075 postmenopausal women, found raised ALT in 6.7% on extract versus 0.7% on placebo (P < 0.001), seven of them classed as serious adverse events. NIH LiverTox scores green tea extract A, a well established cause of clinically apparent liver injury, with more than 100 published cases, including fatal acute liver failure and cases requiring urgent transplant, typically appearing 1 to 6 months after starting. Green tea does not appear in the Menopause Society's 2023 nonhormone therapy position statement.

The grade "limited for weight and cholesterol; none for menopausal symptoms" means: limited — One or two small human trials, or trials for a closely related outcome. none — No human trial evidence we could find for this use. Grades are explained in full on our methodology page.
