Garcinia cambogia, a tropical fruit also known as the Malabar tamarind, is a popular weight-loss supplement. People say it blocks your body's ability to make fat and it puts the brakes on your appetite. It could help keep blood sugar and cholesterol levels in check, too. You'll find it in bottles on the shelf at the store as well as mixed with other ingredients in diet products.
Does it live up to its hype? Maybe a little, but it might not be worth it.
How It Works
The active ingredient in the fruit's rind, hydroxycitric acid, or HCA, has boosted fat-burning and cut back appetite in studies. It appears to block an enzyme called citrate lyase, which your body uses to make fat. It also raises levels of the brain chemical serotonin, which may make you feel less hungry.
But actual weight loss results aren't impressive. A review published in the Journal of Obesityfound that people who took garcinia cambogia in studies lost about 2 pounds more than people who didn't take it. The reviewers couldn't say for sure that the weight loss was because of the supplement. It could have been from the lower-calorie diet and exercise programs the people in the studies typically followed. Better studies are needed to find out if HCA really helps people lose a lot of weight and keep it off.
Type 2 Diabetes and High Cholesterol
Garcinia cambogia may make it easier for your body to use glucose, the sugar your cells need for energy. Mice that got garcinia cambogia in one study had lower insulin levels than mice that didn't. That's another reason, besides weight loss, that people with diabetes are interested in it. However, if you're taking garcinia cambogia along with a medication to control your blood sugar, your glucose could get dangerously low.
Some research has found that garcinia cambogia can also improve cholesterol levels, lowering triglycerides and LDL (the "bad" cholesterol) and raising HDL (the "good" cholesterol). But you shouldn't use it if you're already on a prescription for your cholesterol.
Possible Side Effects
When you take garcinia cambogia, you might get:
In 2009, the Food and Drug Administration warned everyone to stop using a weight-loss product that contained garcinia cambogia because some people taking it got serious liver problems. The product had other ingredients, too, so it's not clear that garcinia cambogia was to blame. While some research suggests the supplement is safe for your liver, other research says no.
Garcinia cambogia may interact badly with:
You definitely don't want to use it when you're pregnant or nursing, or if you have kidney or liver problems. It is possible that manic symptoms may emerge as a side effect.
To Buy or Not to Buy
Since study results are mixed, you should talk with your doctor to help you decide if taking garcinia cambogia is a good idea. Even if it's safe, it may not help you lose much weight. It's probably wiser to spend your money on healthy food or an exercise DVD.

Fat-Loss Hope Or Hype: The Truth About Garcinia Cambogia
Some say it's hyped, but others say it's just misunderstood. Hear from the researcher behind the most important studies and make your own decision!
Garcinia cambogia, also known as the Malabar tamarind, is a small, sweet tropical tree fruit shaped like a pumpkin. In the late 1960s, scientists discovered an acid in the fruit somewhat similar to the citric acid found in fruits like oranges and lemons.
That acidвЂ”called hydroxycitric acid, or HCAвЂ”has ridden a rollercoaster ride of popularity over the last 20 years. It is alternately touted as a miracle weight loss supplement and derided as effective only in rats.
So where is the ride at now? Since late 2012, HCA has taken a steady ascent, and people around the world chat about "garcinia" like that's the name of their new personal trainer. (For the record, garcinia cambogia, hydroxycitic acid, and HCA all refer to the same thing. I'll stick primarily to HCA here to keep it simple). It can feel like anyone with even a passing interest in supplements has gotten asked by a small army of friends, loved ones, and cab drivers: "Is garcinia legit?"
So . is it? Knowing what I know now, this question sounds a little like asking, "Is a hammer legit?" It depends on the hammer and the person swinging it, right? So here's the deal: HCA isn't a miracle; it's a tool. Anyone who has ever suffered the indignity of smashing their finger with a hammer can attest that tools only work when you know what to do with them and then follow through on that knowledge.
Luckily, in recent years we've learned a lot about not only what HCA supplements do in the body, but also how you can make the most of them. Here's what you need to know about this blockbuster fat-loss supplement.
HCA's Early Promise
HCA got its first taste of widespread popularity back in the '90s, after a number of studies concluded that it causedВ weight lossВ in animals. One thing we know is that HCA blocks a portion of an enzyme called citrate lyase, which helps turn sugars and starches into fat.
Block that enzyme, and carbohydrates get diverted into energy production rather than accumulating as body fat. Then, when you burn fat through effective training, there's less to replace it, and your overall fat level goes down.
HCA also seems to have an ability to helpВ suppress the appetite, but not in the same way as a stimulant-basedВ diet pill. Rather, it increases the level of satietyвЂ”satisfaction you receive from foodвЂ”making it easier to eat less. The mechanism by which it achieves this isn't entirely clear yet. The late great nutritionist Shari Lieberman suggested that a metabolic change brought on by HCA may send an appetite-suppressing signal to the brain via the amino acidВ 5-hydroxytryptophan, which is a direct precursor to the so-called "happy hormone," serotonin. Given that subsequent studies have shown elevated serotonin levels in subjects who took HCA supplements, she was likely on to something.
With these two impressive bullet points in its favor, HCA seemed on the verge of the big time, but the buzz faded quickly after a large study published in 1998 in the Journal of the American Medical Association concluded that it had "no effect" on human subjects.
End of the line, right?
Pure Garcinia Cambogia Vs Regular Garcinia Cambogia Garcinia Cambogia Side Effects!
The rind of Garcinia Cambogia contains HCA and is what proponents claim to decrease appetite and prevent the body of accumulating fat.
Not quite. Subsequent research has produced some very different conclusions and helped convince me, among many other previously skeptical people, that HCA has real potential as a weight-loss supplement.
It's All About How You Take It
A few years after the lackluster results in the JAMA study, I had the opportunity to talk about HCA with Harry Preuss, a researcher and pathologist at Georgetown University, who saw enough to like about HCA to keep researching it after its popularity had waned. Preuss, a past president of the American College of Nutrition, told me he thought the previous studies were discouraging but not conclusive.
He decided to take a closer look. "You have to take the right dose of the right product, and you have to take it properly," he told me. "In the JAMA study, they used whatever the dose was at the time, and they never even mentioned the type of citrate they used. You have to give enough so that it reaches the sites in the body that it needs to reach." In recent years, Dr. Preuss has continued to hammer on the idea that maximizing bioavailability with HCA is crucial for its success. Fail to prioritize it, and you set yourselfвЂ”or your study, in the JAMA's caseвЂ”to fail.
It's an old story. Vitamin studies are often done by people who use the wrong dose or the wrong form, and then seem almost gleeful when they're able to proclaim that the supplements "don't work." Prejudice confirmed; case closed.
Dr. Preuss, who went on to lead the most promising human studies into HCA, points out that there are three different forms of hydroxycitrates: those which are blended with calcium, potassium, or magnesium salts. The reason to add these salts is to decrease the degradation of free HCA into HCA lactone, an inactive form of the compound. These salts, which are added at a 1-to-1 or higher ratio in most commercial HCA supplements, also help your body more easily absorb the hydroxycitrate.
"If you have almost a pure calcium hydroxycitrate, it's just not going to work," he told me. He said he prefers hydroxycitrate that is bound to both calcium and potassium; he says the bond dramatically increases the absorption and effectiveness of HCA.
Dr. Preuss and his colleagues put this premise to the test in a study where they followed 30 healthy but overweight people ages 21-50 over an 8-week period. All of the subjects consumed a diet of 2,000 calories per day and walked for half an hour five days per week. One group was given Super CitriMax, a patented form of HCA bound with both calcium and potassium. The other group was given a placebo. At the end of the study, the placebo group had lost an average of three pounds, but the HCA group had lost an average of 12 poundsвЂ”a whopping 400 percent more weight. Their average BMI fell by 6.3 percent; in the placebo group, it fell only 1.7 percent.
To top it off, the HCA group experienced an almost double boost in serotonin levels compared to the placebo group. Higher serotonin levels are associated with fewer cravings, as well as a greater sense of calm. In a second similar study, Preuss and his colleagues tested 60 people, and this time, the HCA group lost an average of 10.5 pounds compared to the placebo group, which lost an average of 3.5 pounds.
"Perhaps the most remarkable result was in appetite control," Preuss says of the second study. "The placebo group had no change, but the HCA group had a 16 percent reduction in the amount of food they ate per meal!"
The Right Way To Supplement With HCA
It's far too easy to view supplements purely from the perspective of either "I take it" or "I don't take it." With some supplements, that's precise enough to see an effect.
You have to watch everything you eat, exercise like a fiend and make other lifestyle changes that don’t come easy.
But the lesson here is thatВ how you take HCA matters. As such, Preuss has taken the new wave of HCA popularity as an opportunity to remind us all about how to get the most out of this supplement, most recently in a paper he co-authored for the Alliance for Natural Health in 2013 titled "Garcinia Cambogia: How to Optimize its Effects."
Here are Preuss' recommendations:
- Choose a preparation that is at a minimum 50 percent HCA and is not composed wholly of calcium salts: Make sure potassium (K) and/or magnesium (Mg) is present. If the product has a low lactone content, that is even better.
- Be sure to take an adequate dose. For a Ca/K preparation used successfully and reported in a peer-reviewed publication, the dose of extract was near 1.5 g, three times per day before meals. In this 60 percent HCA preparation, that approximates 0.9 g of HCA prior to each meal.
- Take the preparation on an empty stomach, i.e., 30-60 minutes before each meal.
- Remember, "If you don't comply, don't complain." Take the right dose at the right time.
Note that he says "near" 1.5 g three times daily. Why not exactly 1.5? Given that HCA supplements come in a range of potencies and mixtures, it can be hard to be exact. Aim for the 1.5 g benchmark, but don't be obsessive.
Why on an empty stomach? It takes advantage of the appetite-curbing effect of the supplement, but even more important, HCA needs some space to work its magic.
"In the presence of food, the hydroxycitrate salt can bind to some of the components in the meal and be inactivated," Preuss writes. "This is called the 'food effect' and can seriously reduce the bioavailability of a number of supplements, not just HCA."
Follow these guidelines, andВ HCAВ can be an addition to your arsenal. Side effects are rare at the kind of reasonable doses that Preuss recommends, and since it's not a stimulant, you don't need to worry about it affecting your sleep or mood. If you're looking to control your weight and are committed to eating right and working out, don't be afraid to add this popular supplement into the mix!
How Garcinia Cambogia Can Help You Lose Weight and Belly Fat
Garcinia cambogia is a popular weight loss supplement.
It is derived from a fruit of the same name, also called Garcinia gummi-gutta or Malabar tamarind.
The peel of the fruit contains high amounts of hydroxycitric acid (HCA), which is the active ingredient believed to be responsible for most of the weight loss benefits ( 1).
This article is a detailed review of garcinia cambogia and whether it is something you should take in order to lose weight.
Garcinia gummi-gutta is a small, pumpkin-shaped, yellow or greenish fruit.
The fruit is so sour that it is generally not eaten fresh, but rather used for its sour flavor in cooking ( 2).
Garcinia cambogia supplements are made from extracts of the fruit's peel.
The peel of the fruit contains high amounts of hydroxycitric acid (HCA), an active substance that has been shown to have some weight loss properties ( 3, 4, 5).
The supplements generally contain 20–60% HCA. Nevertheless, studies show that those with 50–60% HCA may provide the most benefit ( 2).
Bottom Line: Garcinia cambogia supplements are made from extracts of the peel of the Garcinia gummi-gutta fruit. They contain high amounts of hydroxycitric acid (HCA), which has been linked with weight loss benefits.
Many high-quality human studies have tested the weight loss effects of garcinia cambogia.
What's more, most of them show that the supplement can cause a small amount of weight loss ( 3, 6).
This graph summarizes the weight loss results from nine studies on garcinia cambogia ( 7, 8, 9, 10, 11, 12, 13, 14):
The blue bars show the results from the supplement groups, while the orange bars show the results of placebo groups.
On average, garcinia cambogia has been shown to cause weight loss of about 2 pounds (0.88 kg) more than a placebo, over a period of 2–12 weeks ( 3, 15).
That said, several studies have not found any weight loss advantage ( 9, 11, 16).
For example, the largest individual study, which tested 135 participants over 12 weeks, did not find any difference in weight loss between the group that took garcinia cambogia and the group that took the placebo ( 9).
As you can see, the evidence is mixed.
they even offered reshipment but still i didnt received any products.
Garcinia cambogia supplements can produce modest weight loss in some people, but their effectiveness cannot be guaranteed.
Bottom Line: Some studies have found that garcinia cambogia causes modest weight loss, while other studies report no noticeable effects.
There are two main ways garcinia cambogia is thought to help with weight loss.
1. It May Reduce Your Appetite
Studies in rats have shown that those given garcinia cambogia supplements tend to eat less ( 17, 18).
Similarly, some human studies have shown that garcinia cambogia is able to suppress appetite and make you feel full ( 5, 13, 14, 19, 20).
How it reduces appetite isn't fully known, but rat studies have suggested that the active ingredient in garcinia cambogia can increase serotonin in the brain ( 5, 21).
Theoretically speaking, since serotonin is a known appetite suppressant, higher blood levels of serotonin could reduce your appetite ( 22).
However, these results need to be taken with a grain of salt. Other studies have found no difference in appetite between groups taking this supplement and those taking a placebo ( 10, 11, 12, 23).
It may be that these effects depend on the individual.
Bottom Line: Some studies suggest that garcinia cambogia can suppress appetite by inhibiting serotonin uptake in the brain, while other studies have found no effects on appetite or hunger.
2. It May Block Fat Production and Reduce Belly Fat
The most important activity of garcinia cambogia is probably its effects on blood fats and the production of new fatty acids.
Studies in humans and animals have shown it may lower high levels of fat in the blood and reduce oxidative stress in the body ( 24, 25, 26, 27, 28).
One study also suggests it may be especially effective at reducing the accumulation of belly fat in overweight people ( 8).
Another study gave moderately obese individuals 2,800 mg of garcinia cambogia daily for eight weeks ( 14).
By the end of the study, the group had drastically reduced several risk factors for disease:
The main reason for these effects is thought to be that garcinia cambogia inhibits an enzyme called citrate lyase, which plays an important role in the production of fat ( 2, 29, 30, 31, 32).
By inhibiting citrate lyase, garcinia cambogia is thought to slow down or block fat production in the body. This may reduce blood fats and lower the risk of weight gain, two major disease risk factors ( 33).
Bottom Line: Garcinia cambogia blocks the production of new fats in the body, and has been shown to lower cholesterol levels and blood triglycerides in overweight people.
Animal and test-tube studies suggest that garcinia cambogia may also have some anti-diabetic effects, including ( 2, 14, 34):
- Decreasing insulin levels
- Decreasing leptin levels
- Reducing inflammation
- Improving blood sugar control
- Increasing insulin sensitivity
Garcinia cambogia may also have benefits for the digestive system. Animal studies have suggested it helps protect against stomach ulcers and reduce damage to the inner lining of the digestive tract ( 35, 36).
However, these effects need to be studied further before firm conclusions can be drawn.
Bottom Line: Garcinia cambogia may have some anti-diabetic effects and may also help protect against stomach ulcers and damage to the digestive tract.
Most studies have concluded that garcinia cambogia is safe for healthy people in the recommended dosages, or up to 2,800 mg of HCA per day ( 37, 38, 39, 40).
That said, supplements are not regulated by the US Food and Drug Administration (FDA).
That means there's no guarantee that the actual content of HCA in your supplements will match the HCA content on the label.
Therefore, make sure to buy from a reputable manufacturer.
People have also reported some side effects of using garcinia cambogia.
When you place your order, we will ship within 24 hours.
The most common ones are ( 3, 9):
However, some studies have indicated more serious side effects.
Animal studies have shown that a very high intake of garcinia cambogia can cause testicular atrophy — shrinking of the testicles. Studies in rats have shown it may also affect sperm production ( 38, 41, 42).
Additionally, there is one report of a woman who developed serotonin toxicity as a result of taking garcinia cambogia with her anti-depressant medications ( 43).
If you have a medical condition or are taking any medications, consult your doctor before you start taking the supplement.
Bottom Line: Some people experience digestive symptoms, headaches and skin rashes when taking garcinia cambogia. Animal studies suggest that a very high intake may cause toxicity.
Many health food stores and pharmacies offer several varieties of garcinia cambogia.
Choose one from a reputable manufacturer that contains 50–60% hydroxycitric acid (HCA).
Recommended dosages can vary between brands. Generally, it is recommended to take 500 mg, three times per day, 30–60 minutes before meals.
It is always best to follow the dosage instructions on the label.
Studies have only tested these supplements for up to 12 weeks at a time. Therefore, it may be a good idea to take a few weeks off every three months or so.
Bottom Line: Look for a supplement that contains 50–60% HCA and is made by a reputable manufacturer. Follow the dosage instructions on the label.
Existing studies don't agree on the effectiveness of garcinia cambogia for weight loss.
Some studies show it may cause slightly more weight loss than not taking any supplement. This effect is not confirmed, but it is promising.
The positive effects of garcinia cambogia on blood fats may be where this supplement really shines.
