Green Coffee Bean Extract
Green Coffee Bean Extract is a supplement derived from unroasted, raw coffee beans. The key active ingredient is believed to be a substance known as chlorogenic acid, which is largely destroyed in the roasting process that transforms raw coffee beans into the familiar brown beans used to make coffee.
Here are some key points about green coffee bean extract:
- Weight loss: Green coffee bean extract has been shown to be effective in reducing weight in overweight/obese adults.
- Improved glycemic indices and lipid profile: A systematic review and dose-response meta-analysis found that green coffee extract supplementation can improve glycemic indices and lipid profile in adults.
- Other potential benefits: Green coffee has been used for other conditions such as obesity, diabetes, high blood pressure, high cholesterol, and bacterial infections.
Case Studies:
- A randomized, double-blind, placebo-controlled study found that green coffee bean extract was effective in reducing weight in overweight subjects.
- A systematic review and dose-response meta-analysis found that green coffee extract supplementation can improve glycemic indices and lipid profile in adults.
Recommended Dosage:
