Therefore, the benefits of green coffee include the treatment of hypertension and type II diabetes. In addition, the use of green coffee extract in conjunction with diet and exercise may help promote weight loss.
Overall, the chlorogenic acid in green coffee capsules can aid digestion and decrease high blood pressure, providing a number of important health benefits.
What is Green Coffee?
Green coffee extract is obtained from unroasted, green coffee beans. Upon roasting, coffee beans assume their characteristic brown color, and can be used to brew coffee, the popular caffeinated drink.
Though roasting does not affect levels of caffeine in the plant, the process does destroy most of the chlorogenic acid found in the beans. Chlorogenic acid is a chemical compound that is also present in bamboo, peaches, sunflower leaves, and prunes.As an antioxidant, chlorogenic acid is thought to interact with blood vessels to reduce blood pressure and modulate the body's response to blood sugar. Unroasted coffee beans with higher levels of chlorogenic acid are used as an ingredient for green coffee extract.
Green Coffee benefits
- Promotion of possible modest weight loss
- Assistance with diabetes management
- Treatment of hypertension, or high blood pressure
Green Coffee and weight loss
In 2012, the Dr. Oz Show introduced green coffee as a fat-burning supplement that would aid in weight loss. The show cited a study published by Applied Food Sciences, which showed that subjects using green coffee supplements lost 10.5 percent of body weight and 16 percent of body fat with or without diet and exercise over 22 weeks.
The main active ingredient in Green Coffee beans is believed to be the chlorogenic acid. Some human studies suggest that it can reduce the absorption of glucose in the small intestine, which lowers blood sugar and prevents insulin spikes. It has also been shown, that chlorogenic acid may reduce the release of glucose from the liver, forcing the body to burn its fat reserves to produce energy.
Green Coffee and blood sugar
Green coffee extract can be used to modulate blood sugar and manage type II diabetes.
In type II diabetes, an individual develops insulin resistance. Insulin is a hormone that directs the body's cells to absorb glucose from the blood and metabolize the glucose, or break it down into usable energy.
Glucose levels increase in the blood after a meal as the digestive system extracts nutrients from the eaten food. The pancreas then releases insulin to direct cells to take up and use the glucose, thus decreasing the blood glucose to its original level.
However, if an individual develops insulin resistance their cells no longer respond to the insulin's signal to absorb and metabolize glucose after a meal. The unabsorbed glucose then builds up in the blood, and the individual may feel the symptoms of diabetes, which include increased hunger, increased thirst, or fatigue.
Green coffee extract contains chlorogenic acid, which may slow the release of glucose into the bloodstream after a meal.
Who may benefit from taking a Green Coffee supplement?
Individuals can use green coffee extract to aid in weight loss, as the caffeine present in green coffee extract may help decrease appetite.
Green coffee benefits can also include the modulation of blood sugar levels. The chlorogenic acid in green coffee extract is thought to slow the release of glucose into the blood. As a result, green coffee may help decrease symptoms associated with high glucose levels. These may include increased urination, sleepiness, brain fog, inability to focus as well as intestinal bloating.
Individuals with type II diabetes seek to avoid high blood sugar levels, and thus may benefit from supplementing with green coffee.
Green coffee and hypertension
Preliminary research suggests that green coffee can be used to treat hypertension, also known as high blood pressure.
In a 2006 study published in Clinical and Experimental Hypertension, researchers examined the effect of green coffee extract in rats and human beings suffering from high blood pressure,
- The study found that blood pressure levels decreased upon ingestion of green coffee extract - in the rats and in the human subjects. However, blood pressure levels remained unchanged in rats and humans who were only given placebo compounds.
- The study concluded that the chlorogenic acid in green coffee extract is effective in decreasing high blood pressure, and noted that green coffee extract did not cause apparent side effects.
This study therefore suggests that green coffee extract is effective for treating hypertension, and that individuals with hypertension may benefit from supplementing with green coffee extract.
Hypertension is a chronic medical condition in which blood pressure in the arteries is elevated. Sustained high blood pressure increases the risk for coronary artery disease, stroke, chronic kidney disease, and aortic aneurysms.
The chlorogenic acid in green coffee extract is an antioxidant, and is shown to decrease high blood pressure. Individuals with elevated blood pressure may benefit from taking a green coffee supplement.
Who may benefit from taking a Green Coffee supplement?
- Individuals with high blood pressure
- Individuals trying to lose weight
- Individuals with Type II Diabetes
Does Green Coffee have any side effects?
In appropriate doses, green coffee extract does not have any serious side effects. The chlorogenic acid in green coffee extract has not been shown to cause any harmful side effects.
Any possible green coffee side effects are primarily due to the presence of caffeine in the green coffee extract and may include increased urination, nervousness, or stomach upset, headaches and irregular heartbeats.
However, as long as the supplement is taken in appropriate doses, green coffee benefits exceed any adverse side effects.
Green coffee interactions and combinations
There are no reports of interactions and combinations for green coffee extract.
Green coffee and recommendations
Green coffee has been recommended for treatment of both hypertension and type II diabetes. In addition, researchers are continuing to investigate the use of green coffee extract to promote weight loss.
Recommended green coffee dosage is 93 or 185 mg daily of Svetol for high blood pressure. For weight loss, recommended dosage varies according to the brand of green coffee extract. For example, with Svetol 400-800 mg daily is recommended for weight loss.
Why take a Green coffee supplement?
- To support a diet to lose weight
- Avoid feeling fatigued after a meal due to slower release of glucose
- Help manage high blood pressure
- Protect against heart disease and other chronic health conditions
- Increase your body's metabolism
