Also known as Brindleberry and Malabar Tamarind, Garcinia Cambogia which is popular in Dischem stores across South Africa, is a small, pale green fruit, resembling a miniature pumpkin, which turns yellow when ripe.

This fruit originates from Indonesia, having been used in the cooking of curries for many years and, according to the locals, has digestion activating properties.

Studies have shown that extract taken from the skin of the Garcinia Cambogia fruit is useful to dieters in at least three ways:

  • It slows down the conversion of carbohydrates into fat
  • It suppresses the appetite, preventing cravings

How exactly does Garcinia Cambogia work as a weight loss aid?

The primary ingredient found in the skin of Garcinia is Hydroxycitric Acid or HCA, which prevents the formation of fat in the body, by blocking the enzymes which convert unused glucose into fat, also resulting in an increase in metabolism.

HCA naturally increases the level of serotonin in the brain, which enhances mood and boosts energy, putting a stop to binge eating by suppressing the appetite.

Whilst the scientific evidence is by no means conclusive, a growing number of human clinical trials seem to demonstrate that an appropriate dosage of Garcinia Cambogia can have a statistically significant effect upon weight loss (see for example http://www.ncbi.nlm.nih.gov/pubmed/22530711).

Our clear winner – Garcinia Cambogia Extra

This particular brand, Garcinia Cambogia Extra, is certainly a market leader in both the USA and UK. It meets all of our requirements listed in our full buying guide listed further down.

The company’s money-back guarantee appears to be comprehensive and the prices offered by the website are very competitive. Most importantly, the dosage of garcinia extract per capsule is 1000mg and the level of HCA an impressive 60%.

For dieters who can’t decide whether they prefer to try Garcinia Cambogia or raspberry ketone, Garcinia Cambogia Extra allows you to try both simultaneously: the product includes 200mg raspberry ketone, which is claimed to boost the metabolism as well as aiding fat reduction.

Since raspberry ketone is one of the most costly diet supplement ingredients, its inclusion in Garcinia Cambogia Extra at these prices, is quite remarkable.

Also worth consideration – Garcinia Pure

There are no gimmicks attached to Garcinia Pure: this is simply 100% natural Garcinia Cambogia extract and nothing more at a good price.

The most impressive feature about this product is the dosage: each vegetarian capsule gives a 1000mg serving of garcinia extract, which should be taken three times per day, giving a daily dosage of 3000mg.

With an HCA of 60%, this product conforms precisely to the best scientific guidelines available relating to strength and dosage. It is free from caffeine and other stimulants, so can be taken by those suffering from caffeine intolerance.

What do need to know before buying Garcinia Cambogia extract? – Our no-nonsense buyers guide

A Google search for ‘Garcinia Cambogia Extract’ produces over a million hits, which leaves would-be dieters with a gargantuan problem: precisely what should they be searching for in a garcinia supplement? The best advice is to follow our checklist below –

  • Check out the manufacturer/supplier Look at the official website to see where the supplement has been produced. Avoid purchasing products manufactured in countries such as China, where reports suggest that inferior ingredients may be used; if the website provides no details of where and by whom the product was manufactured, don’t buy it.
  • Make sure that you are paying only for what you order. Look at the small print to ensure that the supplier is not operating an autoship programme under which your bank account will be debited at regular intervals for products you did not want. These programmes are very difficult to cancel.
  • Check out the company’s guarantees. Some companies offer full refunds to customers who are dissatisfied with their product. Don’t forget to look carefully at the terms and conditions attached to guarantees: does the company offer to refund the cost of the entire order, or only that part of the order which is returned unopened?
  • Check the products label. The product’s label should list all ingredients, including quantities. Don’t risk taking a supplement without knowing what is in it and don’t buy a product that doesn’t list ingredients on its label.
  • What’s the percentage of HCA? Hydroxycitric Acid (HCA) is the active ingredient which makes Garcinia Cambogia effective in eradicating and blocking fat. The scientific literature suggests that the level of HCA must be at least 50% (preferably 60%) if a product is to be effective.

    Det er her vores gurkemeje piller kommer ind i billedet.

    Don’t buy Garcinia Cambogia if the manufacturer fails to publish the percentage of HCA or if the level is below 50%.

  • Check the price. The process of extracting garcinia from the peel of the fruit is complex, which makes Garcinia Cambogia supplements quite expensive. Make sure you compare the prices of different products carefully, calculating the daily cost of each according to the recommended dosage.

What is the normal Garcinia Cambogia dosage required to see results?

The recommended dosage for adults is between 500mg and 3000mg of pure Garcinia extract each day. Typically a 1000mg pill is taken 2-3 times a day, 30-60 minutes before food.

The research suggests that Garcinia Cambogia can provide very helpful support to dieters and may assist them to reach their goals by reducing fat and suppressing appetite.

Scientific studies also demonstrate it can lower cholesterol, reduce inflammation and protect the body from oxidation.

Garcinia extract is also completely safe to use. For those determined to shed unwanted pounds, Garcinia Cambogia extract is certainly worth considering.

Our two top choices in order of effectiveness would be Garcinia Cambogia Extra and Garcinia Pure – these are probably the pick of the bunch based on our comprehensive buying guidelines.

Garcinia Cambogia: Does This Hyped Weight Loss Supplement Really Work?

Garcinia cambogia (GC) is a small, pumpkin-shaped fruit that grows in Southeast Asia and India. The key active ingredient found in the rind of garcinia cambogia is hydroxycitric acid (HCA), which some research suggests can help certain people lose weight. (1)

Currently, there are at least 14 separate HCA-containing products sold over-the-counter to consumers labeled as “garcinia cambogia.” Most people are drawn to the idea of using GC because of the potential that it can provide near-effortless, quick weight loss without the need to change someone’s overall diet or lifestyle very much.

GC itself is not a new product; in fact, it’s been consumed in parts of Asia for many years, although not for the purpose of losing weight. Since GC (traditionally also known as the Malabar tamarind) first began to gain popularity in the U.S. several years ago — after appearing frequently in the media and on popular health-related TV shows — sales have gone up dramatically. More and more people are purchasing this so-called “weight loss miracle drug” in hopes of losing stubborn body and stomach fat they’ve been struggling with for years.

But just like most other weight-loss supplements, pills and products, studies regarding GC’s effects and safety have been mixed. While there’s some evidence that HCA might be able to aid in weight loss even when someone does not exercise often or change his or her diet very much, there’s also concerns regarding serious side effects that can occur, including liver damage or failure, anxiety, fatigue, dizziness, and digestive problems.

Remember that just because GC is derived from a natural fruit doesn’t mean it’s always completely safe. So is garcinia cambogia ultimately worth trying? What’s the truth with this purported weight-loss supplement? Let’s take a look at how HCA works, in what situations GC might be helpful, and what adverse reactions are possible when using any type of weight loss drug.

Finally, it’s worth considering the fact that time and time again we see various fad diets and products publicized to help boost weight loss — but what really works in the end is living a healthy lifestyle long term.

Does Garcinia Cambogia Work? What the Studies Tell Us

Garcinia cambogia reviews, research results and weight loss testimonials have been mixed to say the least. By far the most well-publicized benefit of using garcinia cambogia is its ability to increase weight loss. Other claims that are commonly made about garcinia cambogia’s effects include:

  • loss of appetite or less of a desire to eat than usual
  • reduced cravings for unhealthy foods, such as sugar addiction
  • a more positive mood (including feeling happier, more energetic and less tired)
  • increased energy and concentration
  • stabilized blood sugar levels
  • improved bowel movements
  • reduced joint pains
  • improved cholesterol levels
  • stronger desire to be physically active

Most of the claims above have not been backed by scientific studies, however some have. Let’s review the benefits of garcinia cambogia that actually have some merit and seem to be effective in some manner.

Some studies have found that garcinia cambogia might, in fact, be able to help with low amounts of fat loss, plus some of the other health concerns mentioned above, although its effectiveness is rarely strong or consistent.

De beste manier om een beeld van de ervaringen van een afslankmiddel te vormen is door op zoek te gaan naar geverifieerde aankopen.

2 , 42 Toxicology Toxicology studies resulted in no toxicity or deaths in animals at HCA dosages of 5,000 mg/kg, equivalent to 350 g or 233 times the maximum dose of 1.5 g/day of HCA.

For example, research suggests that HCA works by blocking a certain enzyme called adenosine triphosphate-citrate-lyase, which contributes to the formation of fat cells. But studies comparing GC’s effects to controls have found that it might only increase weight loss by a mere one to two pounds on average.

These findings are exactly what researchers published in the Journal of Obesity in 2011. When they compared people who took garcinia cambogia extract to those who didn’t, the weight difference was very small (on average just about two pounds). Plus, it wasn’t even possible to conclude that GC was directly responsible for the additional pounds lost.

The meta-analysis reviewed results from 12 different trails involving GC and revealed a small, statistically significant difference in weight loss favoring use of garcinia cambogia products containing HCA slightly over use of a placebo. However, the analysis also found that some studies showed digestive side effects (“gastrointestinal adverse events”) were twice as common in HCA groups compared with placebo.

Results from various weight loss studies involving GC have been very mixed. One study in the meta-analysis reported a significant decrease in fat mass in the HCA group compared with placebo, two studies reported a significant decrease in visceral fat/subcutaneous fat/total fat areas in the HCA group compared with placebo, but two other studies found no significant difference at all between HCA and placebo. A study that was published in the Journal of the American Medical Association found that GC used for 12 weeks (1,500 milligrams dosage) “failed to produce significant weight loss and fat mass loss beyond that observed with placebo.” (2)

The conclusion of the meta-analysis regarding garcinia cambogia? Researchers summed up their findings by saying that “the magnitude of the effects are small, and the clinical relevance is uncertain. Future trials should be more rigorous and better reported.” (3) The bottom line is that if you’re struggling to lose weight, GC likely won’t be the answer, according to trial and controlled studies.

Studies have also suggested that it’s possible that HCA found in garcinia cambogia can help lower someone’s appetite by increasing production of the neurotransmitter serotonin, which is associated with calm and happy feelings — and therefore, sometimes appetite suppression, less cravings and reduced desire for comfort foods. Animal studies show it might also help increase energy expenditure. (4)

Keep in mind, however, that this isn’t the case with all people, and there are other, potentially less risky ways to better manage your appetite and boost serotonin production (such as eating balanced meals with protein foods and healthy carbs at regular times throughout the day).

There’s some support for garcinia cambogia being able to improve cholesterol levels and lower high triglycerides. It might also be able to help raise HDL “good” cholesterol. It’s not safe for anyone already taking medications that affect cholesterol, however, and its effects don’t seem to be very reliable or strong.

Studies have found that GC has “no significant effect on anthropometric parameters, REE, triglycerides or glucose levels” but might have a small effect on lowering cholesterol. (5) Keep in mind that there are also plenty of other natural ways to improve cholesterol levels, including exercising and eating more dietary fiber from high-fiber foods like veggies, nuts, seeds and beans.

Finally, what about CG’s effects on blood sugar levels? Some evidence exists showing that garcinia cambogia can help control blood sugar by improving how cells take up glucose (sugar) to be used for energy. One way in which it might improve weight loss is through inhibition of pancreatic alpha amylase enzymes, changes in intestinal alpha glucosidase and alterations in fatty acid synthesis. This might be able to change how carbohydrates are metabolized. (6)

This might possibly help your body respond to insulin better, although it can raise the risk for having low blood sugar levels in some people, too. If you have a history of blood sugar swings, you’re prediabetic, diabetic or taking medications that alter insulin’s effects, GC might make your blood sugar drop dangerously low. While this doesn’t appear to happen in everyone who takes GC, it’s something else to consider and something to discuss with your doctor.

Potential Garcinia Cambogia Side Effects

While some people claim they don’t experience any side effects at all from using GC, others have had very different experiences.

In fact, they do have similar appearances, but the Malabar tamarind gets a red or yellowish color when it ripens, making it look a lot like a pumpkin once it is ready for consumption.

Here’s one disturbing account regarding the use of garcinia cambogia extract that you might not have heard about: It’s contributed to at least several patients winding up in the hospital with liver failure and needing emergency liver transplants.

A 2016 article published by the Transplantation Center at the Mayo Clinic reports that millions of Americans regularly use herbal supplements, often in pill form, but aren’t aware of their full effects. Many weight loss drugs pose potential hidden dangers and are “associated with hepatotoxicity and acute liver injury.” (7)

In the case of garcinia cambogia, it can easily be overused and is not very well-regulated. Some manufacturers recommend taking high doses multiple times per day, for example 30 to 60 minutes before every meal for eight to 12 weeks straight. (8) Aside from liver damage, other garcinia cambogia side effects that can occur include:

  • becoming fuzzy or weak
  • fatigue and brain fog
  • skin rashes
  • an increase in catching colds/lower immune function
  • dry mouth and bad breath
  • headaches
  • digestive issues like nausea, trouble eating or diarrhea

Something else to consider about GC is the long list of its potential medical/drug interactions. Many people should avoid garcinia cambogia due to how it can affect other medications, pregnancy, nutrient levels, blood sugar and more. Garcinia cambogia can potentially interact badly with: (9)

  • pregnancy and breastfeeding
  • existing cases of liver or kidney damage
  • medications that are taken to control asthma and allergies
  • diabetes medications and insulin
  • iron supplements (usually taken by people with anemia)
  • pain medications
  • medications used to control mental disorders like anxiety and depression
  • statin drugs that lower cholesterol
  • blood thinning drugs (like warfarin)

How Much Garcinia Cambogia Should You Take?

If you decide that you still want to try taking GC for weight loss or its other benefits, here’s what you need to know about dosage recommendations for products containing HCA:

  • Studies using GC have used a wide range of doses, anywhere from one gram to 2.8 grams daily. Typical doses are ususally between 250–1,000 milligrams per day.
  • Study durations have also varied widely, ranging from using GC between two to 12 weeks at a time.
  • The optimal dose of HCA is currently still unknown. It’s not clear if a higher HCA dosage even means a higher bioavailability of HCA once consumed.
  • There does seem to be a significant correlation between the dosage of HCA and body weight loss, meaning higher doses have slightly more effects.
  • Garcinia cambogia continues to be the most widely used supplement in studies for providing HCA, however aside from GC, HCA can also be found in supplements made from the plant Hibiscus subdariffa.
  • Because most studies have investigated the effects of GC taken for about eight weeks, researchers believe this is ultimately “too short a time to assess the effects of HCA on body weight.”

To err on the safe side, avoid buying garcinia cambogia “formulas” or “supplement blends,” which might fail to report all of the other ingredients included or accurate levels of HCA. Many proprietary formulas are made by manufacturers that only use a fraction of the active ingredient or standard dose to keep costs down. Always read labels and look for the words “pure garcinia cambogia” and “hydroxycitric acid (or HCA) extract” (this should be around 50 percent to 60 percent of the product). If you purchase a blend and see an ingredient listed without an amount, that can be a red flag that you don’t know exactly what you’re getting.

11 Weight Loss Methods That Really Do Work

In just about all studies involving garcinia cambogia, researchers note that it’s hard to tell if any demonstrated benefits (weight loss, reduced cholesterol, etc.) are really due to GC or are actually influenced by other factors like the subjects eating lower-calorie diets or exercising. It’s always possible for any supplement to cause a “placebo effect,” where subjects wind up changing their outlook and habits simply because they believe the product is helping them (even if it isn’t actually doing anything).

Another interesting fact that the Journal of Obesity meta-analsis reports is that most of the included studies “failed to indicate whether or not outcome assessors were blinded, and seven studies did not even specify who funded the garcinia cambogia studies.” While it’s possible that garcinia cambogia might help you lose an additional one to two pounds if you take it regularly, most experts don’t think it’s worth the money or the risk — especially considering its effects are so small and inconsistent.

Ultimately, taking weight loss supplements won’t teach you much about eating an overall healthy diet, finding ways to enjoy exercise, or practicing “intuitive eating” and managing cravings.

First, it helps a person to manage their level of Cortisol, which is the hormone that results from stress within the body.

So what can you do to move in the right direction of losing weight safely? Weight loss efforts should always be realistic, safe and sustainable. Remember that the real goal is to reach a healthy weight and stay there for life. That’s why quick fixes and fad diets have been shown in studies to fail in the long run over 95 percent of the time.

Here are some of my favorite tips for losing weight using reliable methods that really work:

  1. Get good sleep! A lack of sleep (less than seven to nine hours nightly for most people) can mean a lack of weight loss.
  2. Eat more fiber: Adults need to aim for at least 25–30 grams daily from things like veggies, fruit, ancient grains, sprouted legumes and seeds.
  3. Use healthy fats: Coconut oil has natural fat-burning effects just like GC does, plus many more benefits like improving gut health, too. Other healthy fats that can help control your appetite include real olive oil, avocado, fats from grass-fed beef, nuts and seeds.
  4. Utilize adaptogen herbs: Adaptogen herbs like maca, ginseng and rhodiola can help control health conditions that can make it hard to lose weight (like high amounts of stress, thyroid issues, leaky gut, adrenal fatigue, cellular toxicity and candida).
  5. Don’t skimp on protein: Protein foods are satisfying and essential for building muscles. Regularly include proteins like cage-free eggs and wild-caught fish in your meals.
  6. Consume probiotics: Probiotic foods and supplements not only help balance improve digestive health, but they also balance hormones, raise immunity, control your appetite and play a part in weight control.
  7. Switch up your exercise routine: Try burst-training exercises and other forms of high intensity interval training (HIIT) to keep challenging your muscles, work in with a group, add in weight training, and relax with yoga in between workouts.
  8. Stand up more during the day: Sitting for long periods of time is associated with being overweight and a higher risk for obesity.
  9. Sneak more fitness into your day: Take the stairs, do body weight exercises at home. or try wearing a fitness tracker for motivation — try some of these exercise hacks.
  10. Schedule your workouts ahead of time: This makes it much more likely you’ll follow through.
  11. Useessential oils for weight loss: Natural oils including grapefruit, cinnamon and ginger oil can help control your appetite, hormones and digestive symptoms.

Can Garcinia Cambogia Help with Weight Loss?

Is there such a thing as a weight loss miracle drug?

Today’s market is full of “miracle drugs” and supplements that claim to help you drop pounds fast. It’s no wonder they fly off the shelves and into medicine cabinets across the country. TV personality Dr. Oz and others like him have showered praise on one of these products in particular: the controversial garcinia cambogia fruit.

Garcinia cambogia is a citrus fruit that grows in Southeast Asia. An extract from the fruit’s rind, hydroxycitric acid (HCA), has historically been used for cooking, but it has also been used for weight loss. You can buy garcinia cambogia online or at most health and supplement stores. It comes in pill form or as a powder. Let’s look at what, if anything, garcinia cambogia can do for your weight.

Advocates say that HCA, an organic acid, works by making you feel full, reducing your appetite, and affecting your metabolism. It’s this effect that has led many to herald it as a natural weight loss cure. Some say it may also help improve high cholesterol or enhance athletic performance.

The list of garcinia cambogia’s rumored benefits is a long one. It can be hard to determine the truth to the claims about its “miracle” properties. So, how do these health claims match up to scientific research?

1. Claim: Makes you feel full

Verdict: No evidence. An extensive review of the existing research on garcinia cambogia determined that there simply wasn’t conclusive evidence to suggest that the supplement or HCA had any effects on appetite and satiety. Although some rodent studies had positive results, no human studies could replicate them.

2. Claim: Lowers body weight

Verdict: No evidence. Existing evidence doesn’t prove that garcinia cambogia alone can facilitate weight loss.

NOOT VAN DE REDACTIE: Voor een beperkte periode is de leverancier van Garcinia Cambogia bereid om de lezers van dit blog een speciale aanbieding te doen.

A 12-week, randomized, double-blind, placebo-controlled study published in JAMA found that the supplement didn’t help with significant weight loss or decrease in fat mass. Both the control and garcinia group were placed on high-fiber, low-calorie diets.

3. Claim: Speeds metabolism

Verdict: Some evidence. There is some evidence that supplementing with garcinia cambogia can influence fat metabolism. Several studies have found that both mice and humans experience an increase in fat metabolism after supplementing with HCA.

4. Claim: Enhances athletic performance

Verdict: Some evidence. Garcinia cambogia may increase the amount of time it takes to reach exhaustion during exercise, according to one study. Another study that used mice had similar results, showing that HCA enhanced endurance during running.

In addition to knowing how well it works, you’ll also want to know about a supplement’s potential side effects. Reported side effects for garcinia cambogia are mild. They include:

There are still other factors you should consider when deciding whether to use a supplement such as garcinia cambogia.

Drug interactions

As with all dietary supplements, HCA could interact with medications you take. Before starting HCA, be sure to talk to your doctor. Make sure they know about all medications you take, including prescription and over-the-counter drugs as well as other supplements.

Part of the allure of garcinia cambogia is the fact that it comes from a fruit, so it’s considered “natural.” However, this alone doesn’t make it a worthwhile supplement or even safe. The Food and Drug Administration (FDA) recommends using caution with products that claim to be quick fixes, promise fast weight loss, and use the term “natural.” Natural doesn’t necessarily mean safe. There are many poisonous plants that are natural, but can cause you serious harm. Many plants interfere with medication or are actually medications themselves.

More importantly, dietary supplements such as garcinia cambogia aren’t studied or approved by the FDA before they go on the market. Furthermore, supplement makers can claim that their products support normal body functions as long as they have a disclaimer stating that the FDA hasn’t evaluated those statements. In other words, supplements containing garcinia cambogia have not been rigorously tested for effectiveness, quality, purity, or safety.

Possible liver problems

In 2009, the FDA recalled a product that contained garcinia cambogia because it was found to cause liver problems. Research since then has been conflicted, with some citing a link between garcinia cambogia and liver damage and other research finding no link. You should discuss this risk with your doctor.

Long-term use

A review of studies on HCA found that no studies have effectively looked at garcinia cambogia use for longer than 12 weeks. That means there isn’t enough evidence to ensure that it’s safe and effective for long-term use.

The danger of scams

It’s free, so what’s the harm, right? Actually, those free trials for products that claim to help you lose weight fast can present more harm than you might think. From surprise shipping fees to extra charges for products you didn’t realize you ordered, these trials can end up costing you money. For information on how to avoid these scams, check out this page from the Federal Trade Commission.

“Miracle” weight loss solutions rarely live up to the hype. Even when there is scientific evidence of positive results, the results are often so mild and minimal that users are disappointed to learn they still have to exercise and control their eating in order to reap lasting and significant weight loss.

Dr. Oz has come under fire for promoting “miracle” weight loss products on his show. His claims got him into trouble with the U.S. Senate Subcommittee on Consumer Protection, Product Safety, and Insurance. There’s a reason that claims such as his about products with no clear evidence of effectiveness are taken seriously. Many consumers trust his opinion and could be misled into buying something that is, at best, a waste of time and money, and at worst, laden with potential side effects.

According to the FDA, any product, whether natural or man-made, that’s strong enough to work like a drug is capable of producing side effects. Before you add a dietary supplement to your weight loss plan, discuss it with your doctor. They can tell you if the product may be harmful or may be worth a try.

The best approach for weight loss is eating less fat and calories. Choose to eat whole, non-processed foods and burn calories with activity.
