2/5 Weak evidence

Body composition claims evidence brief

Green coffee extract

Green coffee extract contains chlorogenic acids from unroasted coffee beans. It is commonly promoted for weight loss, glucose control, and metabolic support.

May modestly affect weight or cardiometabolic markers in some trials, but the evidence is not strong enough for a confident body-composition recommendation.

Headline Finding

Meta-analyses report modest anthropometric effects, but study quality and durability limit practical confidence.

Dose Context

Chlorogenic acid content, caffeine content, and extract quality vary; older body-composition claims relied on limited or methodologically weak data.

Important Caveat

The body-weight signal is weak and does not support fat-burner positioning.

How To Read This Rating

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.
