Exploring the science and practical methods for incorporating unroasted coffee into your daily wellness routine.
Green coffee powder, derived from unroasted coffee beans, has gained significant attention in the wellness world, largely due to its high concentration of Chlorogenic Acid. This article breaks down what green coffee is, explores the scientific evidence supporting its use for metabolic health—including blood sugar control, blood pressure regulation, and particularly, weight management—and provides step-by-step instructions on how to prepare and incorporate it into your daily routine.

1. What is Green Coffee?
Green coffee refers to the raw, unroasted seeds (beans) of the Coffea fruit. Unlike regular coffee beans, which are roasted to develop their characteristic aroma and flavor, green coffee beans are consumed directly or processed into powder or extract form. This crucial difference in processing ensures that the beans retain high levels of their key active compound: Chlorogenic Acid (CGA). CGA is believed to be responsible for many of green coffee's purported health benefits, especially in boosting metabolism and supporting weight management.
2. Health Benefits of Green Coffee
2.1. Blood Sugar Regulation
A systematic review and meta-analysis, including 10 randomized controlled trials (RCTs), indicated that consuming green coffee bean extract could significantly lower fasting blood glucose levels. This effect was observed to be non-linear with respect to both dosage and treatment duration. Subgroup analysis suggested that the most significant drop in insulin levels occurred when the daily supplement dosage was >=400mg. The proposed mechanisms relate to green coffee’s antioxidant properties, a reduction in intestinal glucose uptake, and the stimulation of AMP-activated protein kinase (AMPK).
Conclusion: Supplementing with chlorogenic acid (green coffee extract) may positively support blood sugar regulation, though further well-designed research is required due to the heterogeneity of existing studies.
2.2. Green Coffee Powder for Weight Loss
The global issue of obesity has led to a search for various effective interventions, with diet and exercise remaining the primary choices over pharmacological treatments or surgery due to potential side effects. A comprehensive meta-analysis (16 RCTs) found that consuming green coffee bean extract significantly reduced the Body Mass Index (BMI, WMD: -0.403 kg/m^2), yet no significant changes were noted in overall body weight (WMD: -0.585 kg) or waist circumference (WMD: -0.847 cm). Subgroup analysis revealed that improvements in BMI were most noticeable in subjects with a baseline BMI >= 25 kg/m^2. Furthermore, supplementation for less than four weeks was found to be ineffective.
Conclusion: Ingesting green coffee bean extract (chlorogenic acid) shows positive effects on improving obesity-related metrics, particularly for individuals with a BMI > 25. More rigorous, large-scale trials are needed to confirm these findings.
2.3. Blood Pressure Regulation
Hypertension, a chronic disease affecting nearly one billion people globally, is a major risk factor for strokes, heart failure, and chronic kidney failure. A systematic review and meta-analysis (9 RCTs) demonstrated that oral intake of green coffee bean extract (with follow-up times ranging from 4 to 16 weeks and daily doses between 46 and 800mg) could reduce both systolic (WMD: -3.093 mmHg) and diastolic (WMD: -2.170 mmHg) blood pressure. Subgroup analysis showed the most pronounced blood pressure-lowering effect in patients with diagnosed hypertension, those taking doses less than 400mg, and those with a follow-up time of 4 weeks.
Conclusion: Oral consumption of green coffee extract (chlorogenic acid) appears to positively benefit blood pressure metrics, but the small sample sizes across studies suggest a need for more extensive, independent trials.

3.1. Using Unroasted Green Coffee Beans
- Soak 1-2 tablespoons of whole green coffee beans in one cup of water overnight.
- In the morning, bring the soaked beans and the water they were soaked in to a boil.
- Once boiling, reduce the heat and simmer for 10-15 minutes.
- Filter the liquid into a cup, discarding the beans.
3.2. Using Green Coffee Powder (The Quicker Method)
- Bring one cup of water to a boil.
- Take 1-2 teaspoons of green coffee powder and pour the hot water over it in a cup.
- Steep the mixture for approximately 5-6 minutes before drinking.
