Green Coffee Beans

Overview: Green coffee beans

Coffee seeds (beans) from Coffea fruits that have not yet been roasted are referred to as "green coffee" beans. Chlorogenic acid levels are reduced during the roasting process. 

Green coffee beans, as a result, have a higher level of chlorogenic acid than conventional, roasted coffee beans. Green coffee contains chlorogenic acid, which is thought to offer health advantages.

After being discussed on Dr. Oz's show in 2012, green coffee became popular for weight loss. It's been dubbed "The fat-burning green coffee bean" on Dr. Oz's show, and it claims to work without exercise or a diet.

Green coffee is used to treat obesity, diabetes, high blood pressure, and other ailments, however, there is little scientific evidence to back up most of these claims.



How does it work? Green coffee beans

Coffee beans that have not yet been roasted are known as green coffee beans. The chemical chlorogenic acid is more abundant in these coffee beans. 

This chemical is regarded to be beneficial to one's health. It may impact blood vessels, lowering blood pressure in people with high blood pressure.

Chlorogenic acid in green coffee is known to impact how the body controls blood sugar and metabolism, which may help with weight loss.


Green coffee beans Uses & Effectiveness

Insufficient Evidence

  • Blood pressure that is too high. According to preliminary studies, ingesting green coffee extract for up to 12 weeks lowers blood pressure in persons with moderate hypertension.
  • A collection of signs and symptoms that raise your risk of diabetes, heart disease, and stroke (metabolic syndrome). According to a preliminary study, drinking green coffee extract lowers blood pressure and blood sugar levels in persons with this illness by a minor amount. However, blood sugar, cholesterol, and other fat levels did not improve.
  • Obesity. In overweight individuals or people with obesity, taking the green coffee extract for 8-12 weeks appears to lower weight by a small amount.
  • Cholesterol levels are high.
  • Alzheimer's disease is a type of dementia.
  • Diabetes.
  • Other circumstances.


To rate green coffee for these purposes, more evidence is needed.



Green coffee beans Side Effects

When consumed by mouth, green coffee is POSSIBLY SAFE if consumed correctly. Green coffee extracts in doses up to 480 mg per day have been used for up to 12 weeks with no side effects. A specific green coffee extract (Svetol, Naturex) has also been used successfully for up to 12 weeks at doses up to 200 mg five times daily.

Caffeine is present in green coffee. Green coffee contains significantly less caffeine than ordinary coffee. Green coffee, however, can have the same caffeine-related negative effects as coffee. Insomnia, anxiousness, and restlessness, as well as stomach trouble, nausea, and vomiting, as well as elevated heart and breathing rates and other side effects, are among them. Coffee used in excess can result in headaches, anxiety, agitation, ringing in the ears, and irregular heartbeats.


Special Precautions and Warnings: Green coffee beans

Green coffee and pregnancy and breastfeeding: There isn't enough credible information to tell if it's safe to drink while pregnant or nursing. To be on the safe side, avoid using it.


  • Abnormally high homocysteine levels: Taking a high dose of chlorogenic acid for a short time resulted in elevated plasma homocysteine levels, which may be linked to illnesses like heart disease.
  • Anxiety disorders: Green coffee's caffeine may aggravate anxiety.
  • Caffeine in green coffee has been linked to the worsening of bleeding conditions.
  • Green coffee's caffeine content has been linked to a shift in the way people with diabetes handle sugar, according to some studies. Caffeine has been linked to both an increase and a drop in blood sugar levels. If you have diabetes, use caffeine with caution and keep a close eye on your blood sugar levels.
  • Green coffee includes caffeine, which can cause diarrhea. Coffee's caffeine, especially when consumed in high amounts, can aggravate diarrhea.
  • Green coffee includes caffeine, which can cause epilepsy. Caffeine in excessive doses should be avoided by those with epilepsy. Caffeine in low amounts should be used with caution.
  • Glaucoma: Caffeine, which is present in green coffee, can raise intraocular pressure. Within 30 minutes, the rise begins and lasts for at least 90 minutes.
  • High blood pressure: Caffeine, which can be found in green coffee, may raise blood pressure in persons who already have it. However, persons who routinely consume caffeine from green coffee or other sources may see less of an effect.
  • Green coffee includes caffeine, which can cause irritable bowel syndrome (IBS). Green coffee's caffeine, especially when consumed in excessive amounts, may aggravate diarrhea that some people with IBS experience.
  • Caffeine from green coffee and other sources can increase the amount of calcium washed out in the urine, which can lead to bone thinning (osteoporosis). This may cause bone deterioration. Limit your caffeine intake to less than 300 mg per day if you have osteoporosis. Calcium supplements may assist in compensating for calcium loss. 
  • Taking up to 400 mg of caffeine daily (about 20 cups of green coffee) does not appear to raise the risk of developing osteoporosis if you are otherwise healthy and get enough calcium from food or supplements. Caffeine should be avoided by postmenopausal women who have a hereditary disease that prevents them from properly digesting vitamin D.



Green coffee beans Dosing

Green coffee dosage is determined by some factors, including the user's age, health, and other circumstances. There is currently insufficient scientific evidence to define an appropriate dose range for green coffee in children and adults.
