About
Green coffee bean extract (standardised to chlorogenic acid) has modest evidence for weight management and blood pressure reduction. Chlorogenic acid is destroyed by roasting — hence 'green' coffee. Evidence is limited and effect size is small.
How it works (mechanism of action)
Chlorogenic acid inhibits glucose-6-phosphatase (reduces hepatic glucose production). Reduces postprandial glucose and insulin spikes. Mild thermogenic effect. Different from roasted coffee due to preserved chlorogenic acid content.
👥 Safety by Population
🚫 Contraindications & Warnings
Contains caffeine — same precautions as caffeine. Blood pressure lowering — monitor with antihypertensives. Weight loss effect modest — 1-2kg over 12 weeks in trials.
