What studies found
A Cochrane review found about 1 kg of average weight change, which wasn't significant in studies outside Japan. Positive results relied partly on caffeine. Catechins alone showed no effect, and this extract is decaf.

Who should take care
Concentrated green tea extract is a known, rare cause of liver injury, with more than 100 reported cases. EU experts flag 800 mg or more of EGCG a day from supplements. It can lower levels of nadolol, atorvastatin and raloxifene. Stop and call your doctor if you notice yellow skin or eyes, dark urine, or unusual tiredness or belly pain.
Talk to your doctor or pharmacist before starting a supplement if you take any medicine, are pregnant or breastfeeding, or have a health condition.
