Green Coffee Bean Extract – Natural Fat-Loss Aid & Anti-Oxidant*
If you’re an avid coffee drinker, you may live by the motto: A cup a day keeps the fat away. After all, coffee contains caffeine – and caffeine has a long and trusted reputation as a mild stimulant weight-loss aid.* As reported in 2010, caffeine may be a “support for fat loss” as it has the potential to increase a person's base metabolic rate (the rate at which he or she expends energy at rest) by 4% or 5%.*
However, caffeine isn’t the only ingredient that contributes to coffee’s metabolism-boosting effects.* The actual green (or raw) coffee bean is a powerful fat loss supporting agent in and of itself, containing high amounts of a key substance known as chlorogenic acid.* Sound familiar? Chlorogenic acid has recently been highlighted on the Dr. Oz show based on studies supporting its role in supporting metabolism.* In fact, several reports on both humans and animals suggest that green coffee bean extract (containing chlorogenic acid) holds great potential as a fat loss support.* Harnessing the power of this pure and natural bean, Labrada has introduced Green Coffee Bean Extract Fat-Loss Optimizer.
Another Reason to "Go Green"
Guzzling extra java is certainly a way to temporarily boost energy – but this won’t deliver the fat-loss support you could experience with Green Coffee Bean Extract.* The key is in the green. Raw coffee beans are a major source of chlorogenic acid, but as soon as you put them through the roaster for commercial coffee preparation, you lose most of the "good stuff" – including the chlorogenic acid and other beneficial polyphenolic substances (not to mention the bean’s natural green color).
Green Coffee Bean Extract from Labrada is a natural powder extracted from unroasted coffee beans to ensure maximum strength and effectiveness. Taking Green Coffee Bean Extract in supplement form is also an easy alternative for people who don’t have the desire (or spare change) to drink multiple cups of coffee per day.
Let’s Talk Fat Loss
In contrast to caffeine – which is a stimulant that increases caloric expenditure and stimulates fat burning and weight loss – Green Coffee Bean Extract promotes fat loss via non-stimulant mechanisms.* While these mechanisms are outlined in further detail in our excellent "Digging Deeper into the science section below by Monica Mollica BSc and MSc.
- May help slow the release of sugar into the bloodstream (especially after large meals)*
- Promoting the activity of your body’s fat-burning enzymes*
- Supporting healthy triglyceride (fat) levels, already in normal range*
In a nutshell, Green Coffee Bean Extract may help support lower fasting blood sugar levels and may even help support healthy after-meal blood sugar levels, already in normal range.* This may help guard against extra body fat storage.
In a study analyzing the human consumption of 200 mg of green coffee bean extract per day, average weight loss results were 5.5 pounds (2.5 kg) in 12 weeks. Results were even more significant with higher daily doses; When up to 1,050 mg (350 mg three times daily) of the standardized green coffee bean extract were consumed, along with diet and exercise, some individuals experienced a weight loss of nearly 18 pounds (8 kg) after 22 weeks.* This higher dosage (complemented by diet and exercise), was well tolerated and did not cause any adverse side effects.
Green Coffee Bean Extract has been reported to have antioxidant properties, similar to those of green tea and grape seed extract.* Antioxidants, by nature, provide support against oxidative stress by helping to reduce free radicals in the body.* In this way, Green Coffee Bean Extract is far more than a fat-loss aid – it’s a natural tool to help you feel your best and help promote overall health.*

Digging Deeper Into The Science
In discussions about the health benefits of coffee drinking, the effects of coffee are often confused with those of caffeine. While it is true that many of the effects of coffee are caused by caffeine, coffee also has several interesting and beneficial non-caffeine related effects.
Chlorogenic acid in Green Coffee Bean - a key player
Coffee contains a myriad of biologically active substances, and recent research has identified chlorogenic acid as being one of them 1. Chlorogenic acid is present in highest amounts in the coffee bean and the seeds inside the coffee berry. Green (or raw) coffee is a major source of chlorogenic acid 2. Commercial preparation of coffee destroys a lot of the chlorogenic acid and other beneficial polyphenolic substances, but heavy coffee drinkers may still ingest from 0.5 to 1.0 g chlorogenic acid per day 3.

Anti-obesity effects of Green Coffee Bean Extract
Several studies in both humans and animals suggest that green coffee bean extract holds great potential as a fat loss support.*
A study investigating the effect of green coffee bean extract on fat accumulation and body weight in mice suggested weight loss with a reduced abdominal (visceral) and hepatic fat content 4.* This effect was attributed to activation of fat metabolism in the liver 4. Another study in mice fed a high-fat diet found that chlorogenic acid not only supported lowered body weight, visceral fat mass and insulin levels already in healthy range, but also supported healthy triglyceride and cholesterol levels, already within healthy range5.* In addition, it was found that chlorogenic acid also promoted adiponectin levels in the blood (more on this below) 5.*
In a study on hamsters fed a high-fat it was found that chlorogenic acid beneficially affected both glucose and fat metabolism, as indicated by supporting healthy levels of fasting blood triglycerides, free fatty acids, total cholesterol, low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), glucose (FSG), and insulin 6, already within healthy range.* This study also suggested a reduction in live fat content6.*
In humans, supplementation of 200 mg green coffee extract per day may support weight loss 7.* Higher daily doses up to 1050 mg (350 mg three times daily) of the standardized green coffee bean extract (Svetol®) may support weight loss of up to 8 kg after 22 weeks, for individuals who also adhered to diet and exercise advice 7.* The higher dose was well tolerated and did not cause any adverse effects 7.*
How does it work?
In contrast to caffeine, which is a stimulant that increases caloric expenditure 11-14 and stimulates fat burning 13,15 and thereby weight loss 16, green coffee bean supports fat loss via non-stimulant mechanisms.* First, green coffee bean slows down the absorption of glucose from the small intestine 17 and lowers after-meal blood glucose levels; the importance of this can be illustrated with the well documented effects seen with low glycemic index foods (enhanced fat burning, increased satiety and fat loss 18-21), which also slow down the absorption of glucose and lower blood glucose levels 22.*
Second, green coffee bean may work to inhibit carbohydrate digesting enzymes 23-26 and the actual absorption process itself 23,27.* This would mean that less glucose gets taken up by the body, and thereby less calories.*
Third, green coffee bean also shifts the site of glucose absorption to more distal parts of the intestine 17, which may support the secretion of the gut hormone GLP-1 (glucagon-like peptide 1). *28,29 This is an interesting effect in that GLP-1 currently is generating much scientific attention due to its involvement in satiety control, glucose homeostasis, and the cardiovascular system. The possible GLP-1 weight loss support has been attributed to a reduction in food intake and slowing of gastric emptying 33.*
Fourth, chlorogenic acid in green coffee bean helps inhibit fat synthesizing enzymes, while supporting the activity of fat burning enzymes 5.*
Finally, as mentioned above, green coffee bean may support blood levels of adiponectin 5,34, a hormone that is secreted from fat cells.* Adiponectin promotes fat burning 35 and also supports insulin sensitivity, and supports healthy blood glucose (blood sugar), already within normal range36-38.*
Supports healthy after-meal blood glucose levels already in normal range*
Another major effect of green coffee bean is its ability to support fasting blood glucose levels 34, and possibly support healthy after-meal blood glucose levels, already in normal range39,40.*
How effective is green coffee bean extract? In mice, green coffee bean extract was suggested to dampen the elevation of blood glucose by 43% after a heavy meal 39.* A notable study in humans tested different dosages of a standardized green coffee bean extract containing 50% chlorogenic acid 40. The subjects were given doses from 100 mg up to 400 mg and then ingested 100 g glucose (which is a standard method of testing of after-meal blood sugar elevations). It was surmised to support healthy after-meal blood glucose levels, already in normal range.* In the group of human subjects who took the 400 mg dose, there was up to a 24% drop in just 30 minutes after glucose ingestion, and a 32% drop after 2 hours 40. *
What determines your blood sugar levels?
While the amount of carbohydrates that you eat, has a significant effect on your after-meal blood sugar levels, this isn't the whole picture. There is an enzyme in the liver called glucose-6-phosphatase (G6P), which is a big player in the blood glucose equation. G6P releases glucose from stored glycogen in the liver into the bloodstream, and also converts protein to glucose 64. Among physically inactive people and those who tend to store body fat around the waist, the activity of G6P is elevated 65-71. Stress also greatly ramps up G6P 66,72.
It is here that chlorogenic acid may help; apart from inhibiting and slowing down the absorption of glucose, chlorogenic acid may also help reduce the activity of G6P 73,74, which may help support healthy after-meal glucose levels already within normal range.*
