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.
NatureWise Pure Garcinia Cambogia
- Research indicates that to have any effect, garcinia cambogia supplements should include HCA in the 50-60% range; these capsules check in at 60%.
- According to Labdoor, these scored very well for purity, meaning you can trust you’re getting a solid dose of HCA.
- Each serving contains 500mg, 300mg of which are HCA.
- These vegetarian capsules are non-GMO and not produced with any artificial additives or fillers.
- These capsules also contain rice bran extract, which may make it unsuitable for folks with rice allergies.
NatureWise trots out a competitively priced garcinia cambogia supplement containing 60% Hydroxycitric Acid (HCA). These vegetarian capsules rank highly for purity in third party testing via Labdoor.
Health Plus Garcinia Cambogia
- Each serving contains 700mg of HCA, placing it on the higher end of the supplements we reviewed.
- In addition to HCA, each capsule contains calcium, potassium and chromium.
- According to third party testing via Labdoor, the HCA in this product is reliable.
- The HCA in this supplement stands at 80%.
- This product includes a 100% money back guarantee if you’re not satisfied.
- Health Plus makes a lot of claims about additional health benefits, including improved moods and increased stamina, but these are not all reliably backed up by research.
Offering 700mg of HCA per dose, Health Plus’s garcinia cambogia supplement sports a good track record of third party testing via Labdoor. Though their marketing may make some hard-to-prove claims, this should be a reliable source of garcinia cambogia.
ZenVita Garcinia Cambogia
- These capsules are very competitively priced, with each serving only setting you back a smidge more than a dime.
- ZenVita’s garcinia cambogia supplement scores very highly for purity in third party testing.
- At 95% HCA, this is one of the highest percentage of HCA you can find in a garcinia cambogia supplement.
- ZenVita does not add any calcium or chromium to their product, claiming that these elements actually dull the effectiveness of HCA.
- While research reveals that you need at least 50-60% HCA for a garcinia cambogia supplement to be effective, there does not appear to be much evidence indicating that 95% HCA is necessarily more effective.
At a cost of only a bit more than a dime per serving, ZenVita has a very competitively priced garcinia cambogia supplement. These “Maximum Strength” capsules contain 95% Hydroxycitric Acid.

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.
- As with many dietary supplements, it’s important to consult with a medical professional before adding garcinia cambogia to your diet.
- Hydroxycitric Acid may play a role in suppressing your appetite. Still, exercise and a well-balanced diet are always going to be your friend in achieving any weight loss goals.
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.
