Garcinia Cambogia Review - Does This Ingredient Really Work? Are mixed clinical results and unhappy customers deal breakers?
If you haven’t looked closely at garcinia cambogia now’s your chance. We created an in-depth review, closely looking at the ingredient, possible side effects and clinical research. We took the time to read countless user comments and experiences found online. At this point, we condensed the facts to give you the information you need.
What is Garcinia Cambogia?
Firstly, garcinia cambogia is an ingredient commonly used in weight-loss supplements. It can also be purchased by itself from a variety of manufacturers. It’s found in Southeast Asia and India and is imported into the United States for use.  It supplies Hydroxycitric Acid, which is supposed to help fight hunger and fat storage.
The history of garcinia cambogia reaches back to the early 1800s, but the first clinical studies appear in the 1990s. Results of research into the ingredient fall on both sides of the debate with some being supportive and others negating any positive results.   You can buy it from countless online and offline retailers.
Mixed Clinical Results – “What To Believe?”
The first issue with pure garcinia cambogia is the lack of clinical support. ”While there are certainly dozens of these pills emerging each year with big claims about weight-loss, there is no real evidence that support the promises,” says our Research Editor.
Research published in the Journal of Obesity claims the effect on weight-loss is small. A study in Critical Reviews in Food Science and Nutrition says, “G. cambogia extracts is associated with body weight and fat loss in both experimental animals and humans,” but goes on to talk about the size and length of testing being smaller than required for clinical significance.
One customer complained, “I waited until I finished the bottle before posting this review, so I wouldn’t make false claims. Now I can say with much confidence that this product did not work for me.”
Another stated, “This did nothing to decrease my appetite. I didn’t notice any fat blocked or weight loss.” 
Though we didn’t find research to back product claims, some users saw positive outcomes. A dieter said, “I can say that I do feel full faster and tend to eat less than I normally would.”
Sometimes less hunger was more than enough. As a buyer claims, “Don’t feel any drastic changes, but I think it is helping to curb some of my appetite.”
The same results can be expected across various brands, like Pure Garcinia Cambogia, Garcinia Cambogia Slim, Supreme Garcinia Cambogia and Tropical Garcinia Cambogia.
Unhappy Customer Reviews – “Time to Worry?”
There are plenty of customer complaints posted on websites like Amazon regarding garcinia cambogia benefits for weight-loss, and how it does not produce real results. One customer said, “I’ve been using these as directed with diet, tons of water, and exercise and I haven’t seen any difference.” 
“No results…neither flatten abs nor change in appetite. Now I have a huge bottle of pills,” said another user.
Slight changes were enough for some users who didn’t mind if it was a fad ingredient. We found one dieter who said, “I haven’t seen much change in my weight but I do feel a bit more energy through the day.”
The same type of comment was common. As another user put it, “It does decrease your appetite a little and gives me slightly more energy.”
Our research has proven that if a specific facet of a weight-loss supplement or program is especially troublesome (pills that make you jittery, fad ingredient, mixed clinical support) the probability of success for the long run is slim. If natural garcinia cambogia really does fail to help many people, this could be a major concern.
The Science – “Is it Legit?”
You’ll have no trouble finding weight-loss claims associated with garcinia extract benefits, but science isn’t so sure it works like that.  For instance, a study in the journal, Evidence-Based Complementary and Alternative Medicine says, “definitive conclusions that Garcinia/HCA supplements are efficient tools against various health problems especially obesity remain to be proven in larger-scale and longer-term clinical trials.” 
The National Institutes of Health Office of Dietary Supplements backs this up when they say there’s, “little to no effect on body weight.”  Another study claims garcinia cambogia extract can “protect against HFD (high-fat diet)-induced obesity, but the research was completed on mice not humans.
Very few companies pay for clinical research, so these studies can also apply to brands, such as Perfect Garcinia Cambogia, Wow Garcinia Cambogia and Pure Asian Garcinia.

The Bottom Line – Does Garcinia Cambogia Work?
Now that we’ve got those ears perked, let’s see where we landed with garcinia cambogia benefits. We certainly appreciate that it is a natural fruit extract and you can find it all over the world, but we definitely feel questionable about recommending this one, because expert feelings are mixed.  The reality is there are few published clinical trials to support this ingredient. And even when studies are supportive, they are often completed on mice. 
For those interested in cutting excess body fat and slimming down fast, we suggest going with a weight-loss supplement that’s backed by real clinical studies, not fad ingredients, and does not cause harmful side effects.
Among the best products we’ve seen this year is one called Leptigen. Its proprietary formula is a combination of four ingredients, and they have been shown in published scientific research to help spark fat loss and ignite metabolism. We didn’t find any negative comments about harmful side effects and user feedback on the web reveals people are seeing great results.
It’s amazing, the company responsible for Leptigen is so confident in their product they’re offering a Special Trial Offer, which is a nice sign.
Previous Garcinia Cambogia Review (Updated July 3, 2014):
What You Should KnowGarcinia Cambogia is a plant native to India and some areas of Asia. More specifically it is a fruit that has been used for both appetite suppression and increased energy metabolism. As part of the citrus family, many people have become interested in this fruit and its potential to help weight loss. In addition, Phenocal , which contains garcinia cambogia, is an alternative marked as a pharmaceutical-grade weight control compound and carries active ingredients such as biotin, conjugated linoleic acid and green tea leaf.
IngredientsGarcinia Cambogia has one main ingredient: HCA. HCA is Hydroxycitric Acid. This ingredient is what makes Garcinia Cambogia an ingredient in many dietary and weight loss supplements.
Product FeaturesThe Hydroxycitric Acid found in Garcinia Cambogia may have several different effects on the body. The most notable of these is it may inhibit the uptake of carbohydrates that are stored in the body as fat. Similarly the Iodine-based Iodoral targets the thyroid, regulates functionality and thus promoting weight loss. By prohibiting the fat storage, the carbs are burned as energy thereby increasing energy levels and decreasing fat levels. Valuable info on this can be found on wikipedia. HCA is thought to prevent cravings for sugar heavy and carbohydrate heavy foods, balance the blood sugar levels, and increase the sertonin levels in the brain which signal to us that we are full faster. There are no known side effects for healthy adults, but for children, women who are pregnant or nursing and those with diabetes or Alzheimer's disease, this is likely not a safe supplement to take. Due to the sometimes illusive nature of these companies it's difficult to find dosage information. For example with Miracle Garcinia Cambogia. This is because of the decreased blood sugar and increased acetylcholine in the brain, which is known to be safe for healthy people. Studies have been and are continue to be conducted on the fruit. So far, the studies have been inconclusive when it comes to being able to show the true benefits. Dieters claim to be mislead by many sellers; the FTC agrees. Sometimes sellers depend on the name alone without providing additional information on their product like with Native Garcinia Cambogia. Some studies have shown weight loss when using Garcinia Cambogia as compared to a placebo, while others have shown there is no remarkable difference. In either case, the fruit has been used for centuries as a weight loss aid. Depending on the merchant and if you purchase Garcinia Cambogia alone or as part of another supplement, you will be able to find it at a relatively inexpensive price. Generally speaking, you will spend about $8 per month on the supplement and that is an incredible price for the benefits it claims to have. It has a reputation for being a fad ingredient, like the Bitter Melon found in Fruta Planta. You will find Garcinia Cambogia as part of the ingredient list for many weight loss supplements on the market today.
- Helps regulate blood sugar naturally.
- Helps to reduce cravings.
- Inconclusive studies to prove benefits.
- May harm those who are diabetic or have Alzheimer's. (See Garcinia Cambogia Side Effects).
- Daily dosages differ from product to product and have not been completely established.
ConclusionThe good thing about Garcinia Cambogia, that we've seen on another garcinia diet pills review, is that is an all natural approach to weight loss, and is safe for the majority of adults to take. It's so popular some generic products are sold by different companies like Vita Garcinia. The bad thing is the fact that there are contradicting studies when it comes to whether or not it will work effectively for many, and it may be harmful to those with diabetes or Alzheimer's. If you are looking to take a weight loss supplement, this is a great one in terms of price, but you may want to look to others that include Garcinia Cambogia as part of the formula.

Garcinia Cambogia Scientific Abstracts:
There have been several studies showing Garcinia cambogia playing a significant role in regulating endogenous lipid biosynthesis. This effect is attributed to (-)-hydroxycitric acid (HCA) suppressing the enzyme ATP-dependant citrate lyase, which assembles the rift of citrate to oxaloacetate and acetyl-CoA. Even though there has been a wide range of studies showing the administration of Garcinia Cambogia extract being associated with weight-loss and body fat reduction, there should be caution as other clinical trials have not been consistent. With that said, a majority of human studies have been conducted in small sample sizes and mostly in the short term. In regards to safety and toxicity, it’s pivotal to note that studies carried out in live organisms have not reported significant toxicity. In conclusion, no reports have been mentioning adverse effects in humans in those treated with Garcinia Cambogia. 
The Journal of Obesity had reported the competence of Garcinia extract, hydroxycitric acid (HCA) as an agent which aids in weight-loss, compiling data from RTCs (randomized clinical trials). The analysis uncovered a small, yet statistically meaningful, difference in weight-loss for hydroxycitric acid over the placebo (MD: −0.88 kg; 95% CI: −1.75, −0.00). There were reports of adverse gastrointestinal effects being twice as usual in those who consumed hydroxycitric acid as opposed to the placebo, thus concluding that the blind clinical trials suggest that Garcinia extracts and hydroxycitric acid do indeed cause short-term weight-loss. The size of the effect is limited to an uncertainty of clinical relevance. In the future, trials should be more stringent with more accurate reporting. 
One report stated the significance of fruits as an important role in dietary components as well as bioactive constituents, which are considered a promising source in the development of an effective and safe weight-loss drug. The pericarp of the Garcinia mangostana has been used for centuries as medical treatments. Products which are derived from mangosteen are vastly used to alleviate metabolic dysfunction and resultant metabolic syndrome. It should be noted that the chemical principals and structures underlying these effects are ambiguous. In the review, it noted the recent chemical and pharmacological testing related to Garcinia mangostana, which included the reduction of body weight, anti-adipogenesis, anti-oxidation activity, and anti-inflammation. The main point of the review is to showcase the effects G. mangostana and its constituents have on weight-loss and treating obesity, which should spark further interest in the development of important therapeutic methods.

Garcinia Cambogia Side Effects:
When thinking about weight-loss supplements, you need to keep in mind that not every natural alternative is free of side effects. Different formulas react in different ways depending on the individual. While Garcinia Cambogia issues are uncommon, there is still a possibility for a negative reaction in some users.
Headaches can be a short or prolonged period of moderate to severe pain resonating in the head. It can travel to the neck, as well. Surrounding tissues near the brain, nerves, and blood vessels will create pain signals, resulting in a headache.
What causes headaches?
Headaches are believed to be the result of changes of blood flow to the brain and the surrounding tissues. The cause of a headache (or cephalgia) can be any number of factors including stress/anxiety, certain types of noise, or even a glare from a computer or television screen. Headaches can result from direct physical stimuli, or an outside agent like caffeine.
Dizziness is the feeling of being faint or losing balance while standing still. Someone who experiences dizziness may feel a false sense of motion, lightheadedness, or the sensation of floating. 
What causes dizziness?
A wide range of factors can be the cause of dizziness, including inner ear disruption, sensory nerves (responsible for dispatching signals to your brain regarding body movement), infection, or poor blood circulation.
Nausea is the unpleasant sensation of feeling as if you are about to vomit. This is typically associated with duodenal contraction, increased saliva, and cold sweats. You may also experience clamminess and shortness of breath as a result.
What causes nausea?
Nausea can be caused by a plethora of factors including motion sickness, excessive eating or drinking, or pregnancy. Eating certain foods may also cause your body to feel nauseous. There may be viral triggers or infectious elements such as influenza or viral gastroenteritis.
Stomach cramps are not a very specific symptom and is typically used to characterize a variety of different issues. Stomach cramps (or stomach aches) are felt mainly in the abdominal region of the body- stomach, gallbladder, colon, small intestine, and can be brought on by a number of different outlying factors. 
What causes stomach cramps?
Stomach cramps are common and can be triggered by eating habits or outside factors like medications, food allergies, or alcohol consumption. Other causes may include hernia, kidney stones, or appendicitis. These conditions cause swelling of tissues and organs which may prompt a stomach cramp.
Garcinia Cambogia side effects are not always a problem, but there have been statements supporting stomach cramps, nausea, dizziness, among others. It should always be standard practice to research and talk with a doctor before taking any weight-loss supplement, especially if you are under the age of 18, taking any prescription medications, have a pre-existing medical condition, or if you are pregnant or nursing.
Garcinia cambogia is one of those ingredients that you find in tons of weight-loss supplements, but the clinical research tends to lean on the side of ineffective. Though we found it difficult to locate any negative side effects, there are a few to speak of.

Garcinia cambogia is a popular ingredient used in weight-loss supplements, meal replacement shakes and health products of all kinds. Research on animals and humans exists, but study sizes are small meaning outcomes may not be clinically significant.

We took a closer look at the Garcinia Cambogia ingredients to give you the information you’re looking for.
Garcinia cambogia is a tropical fruit that also goes by the name Malabar tamarind.
What is it Supposed to Do?
According to WebMD, Garcinia cambogia claims to be able to help with weight-loss, type 2 diabetes, and high cholesterol. The active ingredient is found in the rind, and is called hydroxycitric acid, or HCA.  This is the same active ingredient in supplements like Slimming Garcinia Cambogia, Garcinia Cambogia Slim and Garcinia Torch.
According to research from Virgilli University in Spain, “Although several studies have found that the administration of G. cambogia extracts is associated with body weight and fat loss in both experimental animals and humans, we should be cautious when interpreting the results as other randomized, placebo-controlled clinical trials have not reported the same outcomes. Furthermore, most studies in humans have been conducted on small samples and mainly in the short term. None of them have shown whether these effects persist beyond 12 weeks of intervention.”
This study was not completed on any specific brand (Pure Garcinia Elite, Garcinia Cambogia Plus, Tropical Garcinia, Purely Inspired Garcinia Cambogia), but results are likely the same for this ingredient across all products.
Research published in the Journal of Obesity found that while people who took garcinia cambogia lost about two pounds more than people who didn’t take it. “The evidence from RCTs [randomized clinical trials] suggests that Garcinia extracts/HCA generate weight loss on the short term. However, the magnitude of this effect is small, is no longer statistically significant when only rigorous RCTs are considered, and its clinical relevance seems questionable. Future trials should be more rigorous, longer in duration, and better reported.” 
No matter what a company says about a product or ingredient, the science doesn’t lie. If you head over to the Leptigen review, you can see that there are clinical studies out there that support using natural ingredients for weight-loss.
