Green Coffee Extract
Specifications of Green Coffee Extract
Form: Usually a fine powder or tablets; often off-white to pale brown in color depending on processing.
Caffeine Content: Typically low caffeine levels, less than 10% of extract weight or about 20-50 mg caffeine per serving, which is lower than regular roasted coffee.
Purity and Safety: Free from yeast, gluten, soy, dairy, artificial colors, preservatives, and often tested for microbial contamination and heavy metals.
What is Green Coffee Extract
Green Coffee Extract is a natural supplement derived from unroasted (green) coffee beans, primarily from Coffea arabica or Coffea canephora species. Unlike traditional roasted coffee, the green coffee beans retain a higher concentration of beneficial compounds, particularly chlorogenic acids (CGA), which are the key active bioactive polyphenols responsible for the extract’s health effects. Green coffee extract also contains natural caffeine, though in lower amounts than roasted coffee.
Physical Properties
Appearance: Pale yellow to off-white fine powder.
Solubility: Water-soluble powder, depending on preparation.
Caffeine Content: Typically low, about 1.7-1.9% in water extracts at 60 °C.
Nutritional Information
The extract is valued for antioxidant polyphenols, especially chlorogenic acids that may help with metabolism regulation, glucose control, and modest weight management rather than providing significant calories or macronutrients.
Green Coffee Extract Benefits
Green Coffee Extract offers several potential health benefits mainly due to its rich content of chlorogenic acids and moderate caffeine. Key benefits supported by research and summaries from multiple sources include:
Weight Loss Support: Chlorogenic acids in green coffee extract help boost metabolism, increase fat burning, reduce absorption of carbohydrates, and support maintaining a healthy weight. Some clinical studies showed modest weight loss (about 1.2 kg or 2.6 pounds over weeks) when combined with calorie restriction.
Blood Sugar Regulation: Green coffee extract may stabilize blood sugar levels, improve insulin sensitivity, and reduce inflammation and fat accumulation, helping manage or lower the risk of type 2 diabetes.
Blood Pressure Control: The extract can dilate blood vessels, decrease levels of stress hormones like cortisol, and help lower systolic and diastolic blood pressure by a few mmHg, supporting heart health.
Antioxidant and Anti-Aging Effects: Chlorogenic acids provide antioxidant properties that help neutralize free radicals, protect cells from damage, reduce inflammation, and promote healthier skin by concealing wrinkles and UV damage.
Cardiovascular Health: Studies show green coffee extract may improve cholesterol profiles by lowering total cholesterol and LDL cholesterol, potentially reducing cardiovascular risk.
Mood and Cognitive Support: The caffeine and antioxidants in green coffee extract can enhance alertness, mood, and cognitive function, with potential to reduce risk of neurodegenerative diseases.
Detoxification: The extract may aid in flushing toxins, excess fats, and cholesterol from the body, supporting immune function and overall health.
