ANSWER
Shown below, are green coffee extract dosage levels for weight loss:-
| Green Coffee Extract Specification | No. of participants randomized | Dosage of Green Coffee Extract | Dosage of Chlorogenic Acid | Experiment Duration | Outcome | References |
| Green coffee extract | 50 | 600 mg daily (divided into 3 doses of 200 mg each before meals) | 270 mg of Chlorogenic Acids in a total of 3 doses | 40 days | A weight loss around 1.5 kg was noted. | Blum et al., 2007 |
| CGA enriched green coffee | 30 | 200 mg daily | 90 mg of Chlorogenic Acids | 12 weeks | Average losses in mass in the chlorogenic acid enriched and normal instant coffee groups were 5.4kg and 1.7kg respectively. | Thom, 2007 |
| Green coffee extract | 50 | 400 mg daily (divided into 2 doses of 200 mg before each main meal) | 180 mg of Chlorogenic Acids in a total of 2 doses | 12 weeks | Average of weight loss was4.97kg and 2.45kg in treated and controlled groups respectively. | Dellalibera, 2006 |
Remark: The Green Coffee Extract used in these studies contains >45% of Chlorogenic Acids.
