However, some studies into how garcinia cambogia affects the body seem to indicate that it can negatively affect the liver. Also, some other users of garcinia cambogia also report other side effects.

In this article I am going to look at what science really says about side effects of garcinia cambogia on the liver. I will also look at research into whether garcinia cambogia is safe to use long term and what is the correct dose.


What is Garcinia Cambogia

Garcinia cambogia is a fruit native to countries in Southeast Asia and India. Garcinia cambogia looks like a small pumpkin, and its rind has a sour acidic taste that is used to flavor fish curries. Garcinia cambogia is also called the Malabar tamarind, garcinia gummi-gutta, or kudam puli (pot tamarind).

The National Center for Complementary and Integrative Health says that the rind of garcinia cambogia contains a chemical called hydroxycitric acid (HCA). Scientists have studied the health benefits of garcinia cambogia supplements and say that it is used for losing weight, treating rheumatism, or lowering blood sugar levels.1

According to research published in the journal Fitoterapia, extracts from garcinia cambogia have anti-obesity activity and help to suppress appetite. Also, HCA inhibits the formation of cholesterol and lipids (types of fat) in your blood.2

Does Garcinia Cambogia Work? What the Research Says

What does research say as to whether garcinia cambogia works or not?  A systematic review of medical studies about garcinia cambogia has shown modest results in helping to lose weight fast. Garcinia cambogia works by increasing serotonin levels in the brain and blocks enzymes that create fat in the body.3

For example, a clinical study on the effect of garcinia cambogia for weight loss found that supplementing garcinia cambogia in the diet helped decrease body weight. It also improved glucose intolerance and reduced inflammation in the body.4

Customer reviews of garcinia cambogia supplements are generally positive with many people reporting that it works for them to help losing weight. Some people also combine garcinia cambogia and apple cider vinegar for speedier weight loss.

Let’s look in more detail at other scientific studies on how garcinia cambogia affects your body.

Garcinia cambogia helps reduce body fat

Taking garcinia cambogia for weight loss will also help you lose body fat and visceral fat.

Research published in 2018 in the journal BMC Complementary & Alternative Medicine reported that garcinia cambogia can help obese and overweight people shed excess fat from around their bellies. The patients took a dose of garcinia cambogia extract and Glucomannan of 1000 mg per day from each one. They were advised to have a balanced diet (Mediterranean diet), drink plenty of water, and exercise regularly. After 3 months, the scientists observed a significant reduction in visceral fat and body fat mass.6

Can lower cholesterol

Research has shown that garcinia cambogia supplements also have a positive effect on overall levels of cholesterol in the blood.


For example, the journal Phytotherapy Research reported that HCA helps to lower cholesterol naturally. One group of women took 800 mg garcinia cambogia 3 times a day along with Amorphophallus konjac for 2 months. At the end of the trial, researchers noted that levels of LDL cholesterol were significantly lower than the group of women who took placebo.7

People who suffer from diabetes use garcinia cambogia to help regulate glucose levels in the blood and improve the effects of insulin resistance.

According to a study published in the journal Fitoterapia, garcinia cambogia can help your body metabolize sugar easier. The research suggested that garcinia cambogia can help to lower insulin levels and also help lose weight.8

Garcinia Cambogia: Liver Side Effects

People are concerned about possible side effects of garcinia cambogia on the liver. In 2009, the FDA advised people not to take weight-loss supplements that contain HCA because of possible side effects on the liver.

The World Journal of Gastroenterology reported on cases of people who got serious liver problems after taking supplements containing garcinia cambogia. It was reported that a number of people suffered liver damage after using weight loss supplements containing HCA. However, because the supplements also contained other active ingredients, it was unclear if garcinia cambogia was to blame.9

However, many studies into using garcinia cambogia for its health benefits have not found any link to liver problems.

For example, the journal Fitoterapia commented that most of the cases where issues could exist with garcinia cambogia supplements are with multi-component formulations. Garcinia cambogia hasn’t been confirmed as being toxic to the liver.2

Also, in a previous issue published in the World Journal of Gastroenterology researchers found that HCA extracts and garcinia cambogia didn’t increase toxicity in the liver. In fact, HCA helped to reduce markers of inflammation in the intestines, kidneys, and brain.10


The journal Critical Reviews in Food Science and Nutrition reported that short-term use (less than 12 weeks) of humans using garcinia cambogia supplements hasn’t shown any adverse effects. Taking garcinia cambogia at safe doses usually doesn’t increase side effects in people. The report stated that only in rare cases there have been reports of toxic effect on the liver.11

According to medical studies the side effects of garcinia cambogia are mixed and inconclusive. It’s not recommended to take garcinia cambogia if you have kidney or liver problems.3

However, it was noted that in most trials, none of the patients reported any adverse side effects of garcinia cambogia.12
