What Exactly Is Green Coffee? Everything You Need to Know

Green coffee is becoming more popular in the health and wellness community.

As a result, you may have heard about its high concentration of health-promoting plant compounds.

This article examines green coffee in depth, including its potential benefits and risks.

What exactly is green coffee?

Green coffee beans are simply regular coffee beans that have not been roasted and are therefore unroasted.

Their extract is popular as a dietary supplement, but green coffee, like roasted coffee, can also be purchased in whole bean form and used to make a hot beverage.

Remember that a mug of this light green beverage will not taste like the roasted coffee you’re used to because it has a much milder flavour. It’s said to taste like herbal tea rather than coffee.

Furthermore, despite having similar origins, its chemical profile differs significantly from that of roasted coffee.

It contains a high concentration of chlorogenic acids, which are compounds with powerful antioxidant and anti-inflammatory properties that may provide numerous health benefits.

Roasted coffee contains trace amounts of chlorogenic acid, but the majority of it is lost during the roasting process.


Green coffee beans are unroasted coffee beans that have not been roasted. They have high levels of a type of antioxidant known as chlorogenic acids, which are thought to have a variety of benefits.

Is it effective as a weight loss supplement?

Dr. Oz, an American celebrity physician and talk-show host, promoted green coffee extract as a miracle weight loss supplement in 2012.

Many health experts have since refuted the idea that it has any effect on weight.

Despite this, green coffee extract is still one of the most popular weight loss supplements on the market.

Several small studies on mice found that the extract significantly reduced total body weight and fat accumulation. Human studies, on the other hand, have been far less conclusive.

The majority of human studies on green coffee have been inconclusive. While some participants lost weight, the studies were ill-conceived, with small sample sizes and short durations.

As a result, there is no conclusive evidence that green coffee is effective for weight loss. Human studies that are larger and more well-designed are required.


Green coffee is marketed as a weight loss supplement, but scientific evidence to support its efficacy is lacking. More human studies are required.

Some chronic diseases may be reduced if you take this supplement.

Other than weight loss, green coffee may have health benefits.

In fact, its chlorogenic acids may help lower your risk of developing chronic diseases such as diabetes and heart disease (6Trusted Source).

In an 8-week study, 50 people with metabolic syndrome (a group of risk factors that includes high blood pressure and blood sugar and increases your risk of diabetes and heart disease) were given 400 mg of decaffeinated green coffee bean extract twice daily (7Trusted Source).

When compared to a control group, those who took the extract had significant improvements in fasting blood sugar, blood pressure, and waist circumference.

Although these findings are encouraging, more research is needed.


More research is needed to determine whether green coffee can lower your risk of heart disease and type 2 diabetes.

Potential dangers and side effects

Green coffee is generally safe, but it may pose a few risks.

Caffeine Side Effects

Green coffee beans, like roasted coffee, naturally contain caffeine.

Although moderate caffeine consumption is likely safe for most healthy people, excessive caffeine consumption may result in negative symptoms such as anxiety, sleep disturbances, and increased blood pressure.

Depending on the variety and brewing method, one cup (8 ounces) of either black or green coffee contains approximately 100 mg of caffeine.

Green coffee may contain slightly more caffeine than black coffee due to a small amount of caffeine lost during the roasting process, but the difference is likely negligible.

Meanwhile, green coffee supplements typically contain 20–50 mg of caffeine per capsule, though some are decaffeinated during the manufacturing process.

If you consume green coffee in any form, you should limit your intake to avoid side effects.

It is possible that this will have an impact on bone health.

A two-month animal study discovered that mice given daily doses of green coffee extract had significant calcium depletion in their bone tissue.

These findings suggest that long-term use of green coffee supplements may be detrimental to bone health.

Having said that, human research is required.


Caffeine consumption in excess in green coffee may result in negative side effects. Furthermore, preliminary animal research suggests that it may be harmful to bone health, though human studies are needed.

Dosage recommendations

There is insufficient data on green coffee to make specific dosing recommendations.

Nonetheless, at least one study used doses of up to 400 mg of green coffee extract twice daily and found no adverse effects (7Trusted Source).

If you’re thinking about taking this extract, talk to your doctor first to make sure you’re taking the right amount.


There is no clear dosing recommendation for green coffee, but some studies have used doses of up to 400 mg of the extract twice per day safely.

In conclusion

The raw beans of the coffee plant are referred to as green coffee.

Its extract has gained popularity as a weight loss supplement, and it may promote healthy blood sugar and blood pressure levels, though research on its efficacy is limited.

Although few negative effects have been reported, the caffeine content may cause side effects.

If you’re thinking about incorporating green coffee into your daily routine, check with your doctor to make sure it’s safe for you.

You can also make a hot beverage with the whole beans.
