Pu-erh Tea Extract
Microbially fermented tea popular in China for weight and cholesterol. Human evidence amounts to one small trial with a tiny effect; most of the supporting work is in animals.

What the science says
- Small reduction in BMI in one trial Limited evidence
A randomized trial in preobese and overweight Japanese adults found pu-erh water extract lowered mean body weight and BMI slightly over 12 weeks. It is a single study of modest size and the change was small enough to be of unclear practical value.
- Antioxidant and lipid effects mostly in animals Limited evidence
A systematic review and meta-analysis of pu-erh tea pooled animal trials and reported improved antioxidant markers. Animal data of this kind does not establish a benefit in people.
Dosage & safety
Studied doseThe main human trial used a pu-erh water extract standardized to its polyphenol content taken daily for 12 weeks. Commercial capsules typically provide 500 mg of extract once or twice daily; no dose has been established.
SafetyGenerally well tolerated and low in caffeine relative to green tea, but still caffeinated. Poorly stored fermented tea can carry mycotoxins, so buy from reputable suppliers. Polyphenols reduce iron absorption; avoid taking with iron supplements.
