Garcinia cambogia is a small, pumpkin-shaped fruit native to Southeast Asia and parts of Africa. While the fruit itself is pretty rare in U.S. grocery stores, it’s the source of an increasingly popular weight loss supplement. The extract of garcinia cambogia’s peel contains Hydroxycitric Acid (HCA), a substance that many believe may aid in weight loss (1). Some evidence suggests that HCA may increase serotonin in your brain, which could act as an appetite suppressant (2) (3). There’s also some research that suggests HCA may increase fat metabolism and be useful for reducing belly fat among obese people (4). However, the research is far from conclusive. One of the largest studies on garcinia cambogia until this point was largely pessimistic as to the extract’s role in weight loss (5).
While evidence is split on its effectiveness as a weight loss tool, there are a wide range of garcinia cambogia supplements on the market. These range in terms of potency, and some research indicates that you should look for supplements that contain 50-60% HCA (6). With so many varieties of garcinia cambogia on the market, it’s important to be able to distinguish one product from another.

Although the research on garcinia cambogia’s effectiveness as a weight loss supplement is far from conclusive, some evidence suggests it may play a role in suppressing appetites and cutting levels of fat in blood (7). This supplement’s popularity has spiked in recent years, with more and more manufacturers introducing their own version of garcinia cambogia to the market. With so many options out there, it’s important to know what features to look for.
Hydroxycitric Acid (HCA)
The active ingredient in garcinia cambogia is Hydroxycitric Acid (HCA), an acid found in the peel of this pumpkin-shaped fruit. Studies show that in order to see any effects from garcinia cambogia, it’s important that HCA is in the 50-60% range. Each supplement will have different HCA values – check the label and see what’s listed.
Some garcinia cambogia supplements include additional amounts of various nutrients – such as chromium or calcium – while others stick to HCA.
With any supplement, it’s important to know what you’re putting into your body. Pay attention to third party tests for purity and read the ingredients label to make sure you’re getting what you think you’re getting.
The simplest way to figure out cost is to divide the cost by the amount of servings listed on the label to determine the cost per serving.

Though it’s probably not a fat burning wonder supplement, garcinia cambogia may have appetite suppressing qualities. Before adding it to your diet, consult with a medical professional. If you do decide to check out garcinia cambogia, try to be diligent about how frequently you take it so you can really keep track of any effects you may or may not feel.
