Green coffee beans are simply regular coffee beans that haven\u2019t been roasted and remain completely raw.<\/p>\n\n\n\n
Their extract is popular as a dietary supplement, but green coffee can also be purchased in whole-bean form and used to make a hot beverage, much like roasted coffee<\/a>.<\/p>\n\n\n\n Bear in mind that a mug of this light green drink will not taste like the roasted coffee you\u2019re used to, as it has a much milder flavor. It\u2019s said to taste more like herbal tea than coffee.<\/p>\n\n\n\n What\u2019s more, its chemical profile is quite different than that of roasted coffee, though their origins are similar.<\/p>\n\n\n\n It boasts an abundant supply of chlorogenic acids \u2014 compounds with potent antioxidant<\/a> and anti-inflammatory effects that may provide many health benefits (1Trusted Source<\/a>).<\/p>\n\n\n\n Roasted coffee products also contain small amounts of chlorogenic acid, but most of it is lost during the roasting process (2Trusted Source<\/a>).<\/p>\n\n\n\n SUMMARY<\/strong><\/p>\n\n\n\n Green coffee beans are raw, unroasted coffee beans. They contain high levels of a group of antioxidants known as chlorogenic acids, which are thought to provide numerous benefits.<\/p>\n<\/blockquote>\n\n\n\n In 2012, green coffee extract was promoted as a miracle weight loss supplement<\/a> by American celebrity physician and talk-show host Dr. Oz.<\/p>\n\n\n\n Many health experts have since refuted the notion that it has any significant impact on weight.<\/p>\n\n\n\n Even so, green coffee extract remains one of the most popular weight loss supplements on the market.<\/p>\n\n\n\n Several small studies have treated mice with the extract and found that it reduced total body weight and fat accumulation significantly. However, studies in humans have been far less conclusive (3Trusted Source<\/a>, 4Trusted Source<\/a>).<\/p>\n\n\n\n Most human research on green coffee has been inconclusive. While some participants lost weight, the studies were poorly designed with small sample sizes and short durations (5Trusted Source<\/a>).<\/p>\n\n\n\n Thus, no definitive evidence demonstrates that green coffee is effective for weight loss<\/a>. Larger, well-designed human studies are needed.<\/p>\n\n\n\n SUMMARY<\/strong><\/p>\n\n\n\n Green coffee is marketed as a weight loss aid, but scientific evidence supporting its effectiveness is lacking. More human research is needed.<\/p>\n<\/blockquote>\n\n\n\n Green coffee may have health benefits other than weight loss.<\/p>\n\n\n\n In fact, its chlorogenic acids may help reduce your risk for chronic diseases like diabetes<\/a> and heart disease (6Trusted Source<\/a>).<\/p>\n\n\n\n In an 8-week study, 50 people with metabolic syndrome \u2014 a cluster of risk factors, including high blood pressure and blood sugar, that increase your risk for diabetes and heart disease \u2014 took 400 mg of decaffeinated green coffee bean extract twice daily (7Trusted Source<\/a>).<\/p>\n\n\n\n Those who took the extract experienced significant improvements in fasting blood sugar<\/a>, blood pressure, and waist circumference, compared with a control group.<\/p>\n\n\n\n Although these results are promising, larger studies are needed.<\/p>\n\n\n\n SUMMARY<\/strong><\/p>\n\n\n\n Green coffee may reduce your risk for heart disease and type 2 diabetes, though more research is needed.<\/p>\n<\/blockquote>\n\n\n\n Green coffee is largely safe but may have several potential risks (5Trusted Source<\/a>).<\/p>\n\n\n\n Much like roasted coffee, green coffee beans naturally contain caffeine.<\/p>\n\n\n\n Although moderate caffeine intake is likely safe for most healthy people, too much could lead to negative symptoms, such as anxiety<\/a>, sleep disturbances, and increased blood pressure (8Trusted Source<\/a>).<\/p>\n\n\n\n One cup (8 ounces) of either black or green coffee provides roughly 100 mg of caffeine, depending on the variety and brewing method (8Trusted Source<\/a>).<\/p>\n\n\n\n Because a small amount of caffeine may be lost during the roasting process, green coffee may contain slightly more caffeine than black \u2014 but the difference is likely negligible (2Trusted Source<\/a>).<\/p>\n\n\n\n Meanwhile, green coffee supplements usually offer 20\u201350 mg per capsule, though some are decaffeinated during processing.<\/p>\n\n\n\n If you\u2019re taking green coffee in any form, you may want to moderate your intake<\/a> to avoid effects.<\/p>\n\n\n\n A 2-month animal study found that mice given daily doses of green coffee extract experienced significant calcium depletion in their bone tissue (9Trusted Source<\/a>).<\/p>\n\n\n\n These results suggest that long-term intake of green coffee supplements may harm bone health<\/a>.<\/p>\n\n\n\n That said, human research is needed.<\/p>\n\n\n\n SUMMARY<\/strong><\/p>\n\n\n\n Overconsumption of caffeine in green coffee could cause negative symptoms. Furthermore, early research in animals suggests it may harm bone health, though human studies are necessary.<\/p>\n<\/blockquote>\n\n\n\n Insufficient data exists on green coffee to establish clear dosing recommendations.<\/p>\n\n\n\n\n
