Garcinia Cambogia is a small, sweet tropical tree fruit that contains a biologically active ingredient called hydroxycitic acid (HCA) that has been found in research studies to have some effect on hunger and fat storage (1, 2).
Dishonest marketers soon began to promote Garcinia Cambogia as a miracle pill and make ridiculous claims about its ability to melt body fat.
We examine the dozens of research studies to find out the truth.
How Does Garcinia Cambogia Work?
There have been dozens of studies on Garcinia Cambogia for weight loss in humans and rats.
These studies have found there are 2 different effects it has that benefit weight control.
- Lessens Hunger: It stimulates the body to increase production of Serotonin. This hormone signals the brain when enough food has been consumed so you feel content. This can result in decreased hunger and less calories consumed (6, 7).
- Blocks Fat: It inhibits the production of Citrate lyase, an enzyme that helps produce fat from excess sugars and starches (4, 5).
Clinical Studies for Weight Loss
However, research studies performed with rats aren’t always predictive of what results will be in humans.
We do have several studies carried out with humans. They also show weight loss from taking Garcinia Cambogia, but are more mixed results.
The chart below shows the results of a meta-analysis of 9 different studies that included a total of 706 participants.
Some of these studies show impressive weight loss benefits, and others very little.
However, it should be noted that studies #6 and 7 used the highest dosages of 2.8 grams daily, and showed the greatest amount of weight loss compared to placebo.
Those that showed little or no weight loss all used a dosage of 900 to 1,000mg daily.
So while the average for all 9 studies encompassing 706 participants was 2 pounds more lost than those that received placebo, it appears better results were obtained at the higher dosage, as the authors of the meta-analysis suggest. (20)
SIDE EFFECTS – Generally Recognized as Safe (GRAS)
Garcinia Cambogia is recognized as GRAS by the FDA, meaning it has “been adequately shown to be safe under the conditions of its intended use”.
There have been several studies to test the effectiveness of these products and in these controlled quantities there were no significant side effects.
This meta-analysis examined all published research on Garcinia Cambogia, and found garcinia to be free from any major side effects when taken at dosages up to 2800 mgs per day (with 60% HCA)
WHO SHOULD NOT TAKE GARCINIA CAMBOGIA
It IS safe for most people. But there are a few cases where you wouldn’t want to take it:
- Alzheimers or dementia
Garcinia Cambogia boosts serotonin levels in the brain (which triggers the satisfied, full feeling that helps suppress appetite).
For this reason, it is not advised for patients with neurological disorders such as Alzheimers, Parkinsons, or other forms of dementia.
DOSAGE AND WHEN TO TAKE IT
Dr Harry Preuss is a researcher and pathologist at Georgetown University past president of the American College of Nutrition who has led 2 of the studies on HCA that showed the best results (21,22) He says:
“YOU HAVE TO TAKE THE RIGHT DOSE OF THE RIGHT PRODUCT, AND YOU HAVE TO TAKE IT PROPERLY.”
The 9 studies that were included in the meta-analysis referenced above noted that 1 to 2.8 grams daily were used in testing, and that 2.8 grams seemed more effective (23)
Different studies that have been performed to focus on side effects found no major side effects at dosages up to 2.8 grams daily (24).
Dosage recommendations from those studies are:
- 500 to 1000mg capsules
- 50-60% HCA
- 3 times a day
- 30-60 minutes before meals
- taken with 8 ounces of water
50% HCA means that the manufacturer has standardized the extract to be 50% Hydroxycitric Acid by volume.
50-60% was the highest purity commercially available until recently, so has been the standard used for testing.
Some manufacturers are now advertising 80-95% HCA. This is done for marketing purposes so a brand can claim superiority over other brands.
The higher percentage provides more total HCA per capsule, but is not more effective otherwise.
In other words, the higher HCA % is not “better”, you just need less of it.
For proper dosage, you should lower the quantity if you use a product with HCA % higher than the 60% used in studies.
For example, the maximum recommended dosage of 3 grams per day of a 60% HCA product would yield 1800 mg of pure HCA – the same as 2 grams of 90% HCA.
3,000 mg x 60% HCA = 1800mg pure HCA
2,000 mg x 90% HCA = 1800mg pure HCA
BUYING ON AMAZON – BEWARE THE SCAMS
With any popular diet product, there are lots of scams that sell crappy product at ridiculous prices, and some that dissappear with your money.
You might want to review some guidelines by the FTC in spotting the crooks.
It is becoming more common now with Garcinia, so beware, and read some of our reviews of brands like Ultra, Extreme, Purely Inspired, Miracle, Whole Body, Natural, and Pure Garcinia Cambogia.
Amazon is super convenient, and great at making sure you get what you order. But they don’t do anything to ensure the quality of a product.
Any brand that just popped up yesterday and will be gone tomorrow is NOT concerned with quality.
DR OZ WARNS ABOUT FAKE PRODUCTS
There are now dozens of new “Brands” of Garcinia Cambogia sold on Amazon that just make up a name and throw a label on some garbage product. And, they LIE about what is in the bottle!
The following quote is directly from the Dr Oz website where they warn about such deceptive marketing.
This doesn’t mean all products sold on Amazon are bad. It just warns that products sold ONLY on Amazon are a much higher risk for being very poor quality.
Used in advanced weight loss formulas for many years
Garcinia Cambogia is a safe and healthy weight loss aid all by itself.
But where it really excels is in combination with other products.
Because it is more mild than some other diet aids with no caffeine or other stimulant properties, it has been used for many years to enhance the effectiveness of other products without making users nauseous, nervous, or edgy.
Fat blocking different than fat burning
The “fat blocking” properties are different than fat burning like Green Coffee, so it is complementary to those products. They work better together.
Hunger suppressants not all the same
Even the hunger suppressant is a bit different. It raises serotonin levels in the brain, whereas 5HTP makes the serotonin more readily accessible.
So both have similar effects, but may work differently for different people. And they also can work better together.
SuperFruit Diet Formulas
NewLifeBotanicals includes Cambogia in 3 of their popular Superfruit Diet Formulas. Our customers have been reporting more positive results with these products than any other we offer – in particular the SDF-1 and SDF-2.
Combination products like SDF-1 often use more than 2 ingredients.
They are more convenient, but you can also buy single ingredient Garcinia Cambogia and Green Coffee Bean Extracts and combine them yourself, often for less cost than buying proprietary formulas like SDF-1
