Body composition evidence brief
Green tea extract concentrates catechins such as EGCG, often with or without caffeine. It is commonly promoted for weight management, metabolism, antioxidant support, and health markers.
May produce small changes in obesity indices, but it is not a meaningful body-composition or performance supplement for most lifters.
Dose-response meta-analysis suggests small obesity-index changes; safety and liver-risk context still matter.
EGCG and caffeine content must be explicit; concentrated extracts are not equivalent to brewed tea.
Liver-safety concerns matter, especially with concentrated extracts or fasting use.

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
