Anyone considering green coffee bean supplements should also be aware of potential side effects, interactions with other medications and over-the-counter products, as well as drugs and medications prescribed for certain conditions.
Many users today claim great benefits when using green coffee bean extract or other forms of the supplement in their weight-loss efforts.
Before we go any further, it should be stated that any supplement promoting weight loss or acting as an appetite suppressant should be used in conjunction with a reduced calorie yet nutritious and balanced diet as well as adequate increase in exercise to provide optimal benefits.
While we would all like to think that there is a magic pill out there that will help us shed unwanted pounds and inches, there isn’t.
One study written up in Gastroenterol Res Pract (2011; 2011:382852) “The use of green coffee extract as a weight-loss supplement: a systematic review and meta-analysis of randomized clinical trials” provided a variety of information regarding a number (5) of clinical trials utilizing green coffee extract.
Moderate effect using the extract was noted. Effects were classified as moderate.
While clinical trials involved in researching the health benefits as well as weight-loss benefits of using the extract are encouraging, additional, closely regulated and controlled trials are required in order to come to a definite conclusion.
One of the main components of pure green coffee extract is chlorogenic acid, also known as CGA. Chlorogenic acid is also found in a number of other fruits as well as vegetables.
The amount of chlorogenic acid that a person ingests drinking coffee can range from a 0.5 to 1 g per cup.
Extracting chlorogenic acid from green coffee beans involves a solvent (alcohol) and this extraction of chlorogenic acid from green coffee is marketed as a weight-loss supplement.
Two of the more common such supplements include Svetol and ‘Coffee Slender’.
The main effect of chlorogenic acid, caffeine, and other components in green coffee bean extracts and supplements is its thermogenic effect. The thermogenic effect, also known as thermogenesis, involves the increase of heat in the body.
When the body generates heat, or energy, it enhances the metabolic rate, or the rate at which the body burns fat. Fat and carbohydrates have different thermogenic effects on the body.
The thermogenic effect has been studied for years. One article dating back to 1985 (Metabolism Mar;34(3) 285-93 contains an abstract that breaks this down.
After consuming food, metabolism increases as the body initiates the digestive process. This increase in the metabolic rate also increases body heat. The exact mechanism of action of how feeding affects the thermogenic effect has not quite been determined.
However, it has been determined that carbohydrates can metabolize faster than foods high in fat (0.26 +/- 0.7 v 0.18 +/-0.11 kcal per minute).
It is interesting to note, according to the published article, that a thermogenic effect and response was not noted even when an individual consumed a non-caloric meal.
In other words, not eating will not enhance the metabolism or thermogenic effect in the body in regard to weight-loss efforts.
While there is no such thing as a “weight-loss coffee” per se, consumers may be happy to note that caffeine, chlorogenic acid, and other major components found in green coffee bean extracts and supplements may provide more benefits in weight loss than just waking you up.
Caffeine acts as a stimulant to the body’s central nervous system. Some people are more susceptible to caffeine than others.
In addition, some individuals who drink caffeine or use green coffee bean supplements may find a decrease in appetite, which can have a positive effect on weight-loss efforts.
However, it should be noted that extensive, controlled, and supervised studies regarding the use of weight loss coffee are lacking, and further research in this area needs to be completed before definitive data and statistics regarding the use of green coffee beans for weight loss provides accurate and reliable results.
Not only the chlorogenic acid and caffeine in green coffee bean supplements provide benefits, but so do other components that serve as antioxidants, as well as those that improve blood sugar or glucose levels, although this is noted in animal studies.
You may wonder what metabolism has to do with glucose, which is most often associated with diabetic conditions. However, it’s important to understand that glucose is the body’s main source of energy or fuel.
A calorie is just the medical or scientific term for energy. When your body doesn’t use, consume, or burn up the calories that you ingest, those carbohydrates are converted into fat cells and stored for future use.
Chlorogenic acid is an important component of metabolism in plants, animals, and humans.
A 2010 article titled “Chlorogenic acid exhibits anti-obesity property and improves lipid metabolism in high-fat diet induced obesity mice” determined that there were some positive benefits of chlorogenic acid in weight-loss (in obese mice).
The study analyzed reductions in body weight as well as visceral fat mass and insulin levels when compared to mice who were fed a high-fat (37% fat) diet.
The study noted that the mice who received chlorogenic acid supplements were on a 0.2% high-fat diet, which may be because of the lower concentrations of high-fat foods than the control group that was fed a 37% high-fat dietary intake.
Again, it should be emphasized that weight loss does involve some effort in restricting certain high-fat and high caloric foods for optimal weight loss benefits and long-term weight loss management.
In addition, it should be noted that some individuals are prone to some side effects when taking caffeine supplements or supplements that contain chlorogenic acid such as green coffee bean.
Everyone reacts to supplements differently, and that goes for green coffee bean extract as well.
Some people are more susceptible, as mentioned above, to the side effects of caffeine ingestion, whether from soda or coffee. Common side effects of caffeine ingestion include a sense of jitteriness or shakiness.
The effects of caffeine last anywhere between 15 minutes to two hours, depending on what kind of caffeine you have consumed (coffee versus soda for example).
The Mayo Clinic also suggests that 400 mg or less is considered a moderate intake of caffeine for daily use.
Some of the most common side effect complaints regarding green coffee bean tablets and extract supplements may be due to the caffeine components. You may experience side effects that include:
It is recommended that in order to determine your susceptibility to side effects of green coffee bean supplements and extract that you start at the lowest dose recommended on package labels or as recommended by a pharmacist or your primary care physician.
It’s also important to note that the dosage recommendations and tolerance may depend on numerous factors including age, weight, overall health status, and the presence of any medical conditions common illnesses, or disease processes.
Despite the green coffee bean benefits that can be provided to users, it’s also important to know about proper dosage recommendations, safety issues, and potential side effects.
The plain fact is that caffeine and chlorogenic acid as well as other components found in coffee bean may cause some issues depending on age, a person’s health status, and whether any contributing issues regarding health may exacerbate the effects of caffeine and/or chlorogenic acid.
Nearly 250 products for sale in the supplement market today contain green coffee. It may also be called raw. Always read labels in regard to ingredients and the milligram strength of the supplement you choose.
When it comes to dosage, the most popular forms of green coffee bean extract (Svetol and Naturex) have been studied for up to approximately 12 weeks in clinical research scenarios. Doses of up to 200 mg daily are considered safe.
Another type of green coffee extract (GCA – the registered trademark for Applied Food Sciences, LLC), determined, in a study that lasted six weeks, that between 700 mg and 1,050 mg daily was considered safe.
Chlorogenic acid supplements that have been extracted from green coffee are also determined to be safe when dosage doesn’t exceed 140 mg daily.
One brand of proprietary green coffee bean extract in 800 mg doses recommends one capsule daily.
That capsule contains less than 5% caffeine and 50% chlorogenic acid, and doesn’t contain any binders or fillers or other artificial ingredients.
The warning on the label states that the product does contain approximately 20 mg of naturally found caffeine, which equates to about just under one half a cup of the hot beverage.
As you can see, it takes time to review comparisons and to determine the limits of caffeine intake for the average adult in order to determine whether you may be at risk for any side effects.
Again, everyone reacts to supplements differently, including caffeine and chlorogenic acid
Many people find it effective to combine use with raspberry ketone supplements. Others stick with just the green coffee with brands such as:
Caffeine found in numerous daily food products contain different milligram strength, and a person’s susceptibility depends on how much of those foods are consumed on a daily basis.
For example, a can of soda may contain approximately 45 mg of caffeine in a 12-ounce drink. Energy drinks, gum, and other snacks and candies can contain anywhere from 40 to 100 mg per serving.
A cup of coffee generally provides 100 mg per cup of coffee, while a 1.5 ounce chocolate bar can contain up to 45 mg of caffeine. Add the milligrams up if you consume one or more of these products daily.
Some of the most common side effects of caffeine include:
Stopping caffeine ingestion may also prompt some symptoms of withdrawal that include:
Caffeine can have an impact on overall health and wellness as well. For example, large intake of caffeine can inhibit calcium absorption that may eventually lead to conditions like osteoporosis or thinning bones.
Some heavy drinkers of caffeine products may be at an increased risk of fibrocystic disease, including finding sometimes painful lumps on the breasts.
Reducing risk to health problems and side effects is important. The American Medical Association Council on Scientific Affairs recommends two to three 8 oz. cups of drip or brewed coffee daily. That amounts to 200 to 300 mg of caffeine.
When it comes to soft drinks and tea, limit servings to five, although soft drinks may contain excessive amounts of calories that can lead to weight gain and obesity. Consumption of 80 ounces or more of coffee daily is considered excessive.
– It is recommended that due to insufficient information and data regarding ingestion of caffeine, chlorogenic acid and other components of green coffee bean, that pregnant or breast-feeding women should avoid use.
It should also be mentioned that many of the extracts sold on the market today are decaffeinated, which will reduce caffeine-related side effects.
For example, one trial tested the extract with approximately 140 mg of chlorogenic acid per serving that was taken on a daily basis for four months with no adverse effects.
The same applied to extracts providing 46 mg, 93 mg, and 185 mg once daily for approximately 28 days.
Studies continue on the effects of additional components in green coffee extract including caffeic acid, the aforementioned caffeine and chlorogenic acid, and other components including acrylamide, diacetyl, and hydrogen peroxide – very small amounts generated in the roasting process, and mycotoxin contaminants that commonly occur during the drying process.
(Myotixins such as the fungus Aspergillus ochraceus may be found more commonly in coffees that have undergone the roasting process in tropical and humid locations such as Africa and Vietnam).
Interactions and contraindications of green coffee bean usage should always be discussed with your doctor, especially if you’re taking prescription medications. Interactions with certain drugs have been noted when it comes to the extract.
Moderate interactions may occur with a number of anticoagulants or anti-platelet drugs due to the enhanced effect of caffeine in blood thinning capabilities.
Common anti-platelet medications can include aspirin to Plavix and Persantine, among others. Anticoagulants include Coumadin, Lovenox, and Fragmin, among others.
Green coffee bean may also interfere with the efficacy of drugs like Fosamax and anti-diabetic drugs that have an impact on blood glucose control and blood glucose or blood sugar levels in the body.
Avoid use of the supplement when taking any antihypertensive prescribed to lower blood pressure.
It also has the potential to decrease blood pressure, so when used in combination with prescription medications may cause the blood pressure to dip too low.
Also avoid use when being treated with any type of heart condition medications, as well as Cimetidine (Tagamet) due to the risk of adverse effects caused by caffeine in green coffee bean max products.
Talk to your doctor about the use of the supplements before you buy them or extract if you’re being treated with any monoamine oxidase inhibitor (MAOI), some antibiotics including Cipro and any other drug that promotes stimulant effects in the body including nicotine, amphetamines, sympathomimetic amines, cocaine, and so forth.
The extract may also interact with other herbs and supplements that include but are not limited to those that have an effect on blood glucose levels, blood pressure levels, and vitamins and minerals including calcium, iron, and magnesium.
Before getting green coffee beans for sale, confer with your pharmacist or physician to determine safety, efficacy, and proper dosage based on your needs and goals.
