Green Tea Extract and Weight Loss
Green tea extract is common in weight-management supplements; any effect should be described proportionately to the evidence.
Weight evidence
NIH's dietary-supplement resources characterize possible weight effects from green tea as small rather than dramatic.
Safety
Concentrated extracts are not equivalent to drinking ordinary brewed tea and can carry safety concerns.
Buying implication
Do not infer a large finished-product effect from the presence of green tea extract alone.
