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.

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.

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.

Dieters just place 1 ml of extract underneath their tongue and hold for approximately a minute.

Researchers showed that both placebo groups and HCA groups in case studies lost weight, but the HCA groups consistently lost more weight and experienced powerful appetite suppression along with other health benefits of garcinia cambogia.

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. 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.

This is partly due to an endorsement given by the famous Dr Oz on his TV show a few years ago.

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.

Also, Garcinia Cambogia is affordable, which makes it available for everyone.

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.

What Is Garcinia Cambogia?

The Malabar tamarind was once just the less popular cousin of a trendy fruit, the mangosteen. But now, nutritional supplements containing extracts of the fruit with the scientific name Garcinia cambogia have become the rage, touted for their purported ability to curb appetite and stop weight gain.

The Malabar tamarind, also known as the gambooge fruit, grows across southwest India, Myanmar and Indonesia. It ripens to a red or yellowish fruit about the size of an orange, but resembling the shape of a pumpkin.

People have long used the dried gambooge rinds for chutneys or curries, and sometimes as an aid for stomach problems. But in the late 1960s, scientists identified a substance in the rind of the fruit called hydroxycitric acid, or HCA, which has some potentially attractive qualities.

"Some studies have shown that HCA stops an enzyme that turns sugar into fat," said Catherine Ulbricht, senior pharmacist at Massachusetts General Hospital in Boston and co-founder of Natural Standard Research Collaboration, which reviews evidence on herbs and supplements.

A fruit extract that could interfere with the body's production of fat? The appeal is obvious. However, good results in test tubes don't always translate to an entire person.

Does Garcinia cambogia work?

Some studies say HCA works, and some say it doesn't. Animal studies of HCA showed that mice taking the substance ate less, lost weight and produced less fat from sugar.

Human studies had more conflicting results. One weight loss trial showed no difference between people who took Garcinia cambogia and those who took a placebo pill. Other trials linked HCA to weight loss and healthy blood lipid levels (lipids are fats).

"Further, well-designed clinical trials are needed before any firm conclusions can be made," Ulbricht said.

If a pharmaceutical company wanted to sell HCA as a drug, the company would have to find stronger evidence that the substance worked, coming from better-designed clinical trials. Without that data, HCA wouldn't pass U.S. Food and Drug Administration approval, Ulbricht said. But the FDA doesn't put chemicals sold as nutritional supplements under the same burden of proof as pharmaceuticals.

In fact, supplement makers only have to make their products safe to eat and responsibly label them.

Acute necrotizing eosinophilic myocarditis in a patient taking Garcinia cambogia extract successfully treated with high-dose corticosteroids.

Also, recent laboratory tests showed that most supplements sold online contain substantially less HCA than the label claims.

Despite the popularity of Garcinia cambogia, it is difficult to track how effective supplements containing it are.

"Preparation of products may vary from manufacturer to manufacturer, and from batch to batch within one manufacturer," Ulbricht said. That makes it difficult to compare one brand to another or even to measure the effects of a single brand.

Is Garcinia cambogia safe?

People may safely eat the fruit, of course. And clinical trials have shown it's safe to take Garcinia cambogia extract by mouth — at least for 12 weeks, the length of the studies.

But take caution. Garcinia cambogia has side effects — it may lower a person's blood sugar, so it can interact with diabetes treatments. The fruit hasn't been adequately studied in pregnant women or women who breastfeed. And Garcinia cambogia may be a problem for patients with Alzheimer's or other forms of dementia, Ulbricht said.

In 2009, the FDA issued a safety warning after receiving more than 20 reports of severe reactions, including liver damage, in people taking the supplement Hydroxycut. At the time, Hydroxycut contained Garcinia cambogia extract and other compounds, including chromium polynicotinate and Gymnema sylvestre extract.

A case study published in 2016 in the World Journal of Gastroenterology by Keri E. Lunsford, et al., examined an instance where Garcinia cambogia caused hepatic failure resulting in the need of a liver transplant. The subject had taken the supplement for several months before his liver had failed. The researchers report that this is the first known case of acute liver failure known to be tied to Garcinia cambogia. Liver damage due to other drugs and alcohol had been ruled out, and Garcinia cambogia was the only supplement or drug that the patient had ingested. Much more research is needed in this area, according to the researchers, and in the meantime, the public should be made aware of the potential risks of taking this supplement.

Ulbricht said it's unclear if the Garcinia cambogia extract caused the liver damage.

The bottom line is that people should tell their doctors before trying a new supplement, including Garcinia cambogia and HCA, she said.
