Quick answerGarcinia cambogia is a tropical fruit whose rind contains hydroxycitric acid (HCA), sold as an appetite and weight loss supplement. The NCCIH says it is unclear whether it helps: some studies show a modest effect and others show none. Safety is the bigger issue. NCCIH says it may be unsafe, and NIH LiverTox rates it a likely rare cause of liver injury, including cases of liver failure that were fatal or needed a transplant, sometimes with products labeled garcinia alone. It can also interact with serotonin drugs. For most people, the risks outweigh the uncertain benefit; talk with your doctor about proven weight loss options instead.

What garcinia cambogia is

Garcinia cambogia (Garcinia gummi-gutta), also called Malabar tamarind or brindle berry, is a tree native to India and Southeast Asia. The National Center for Complementary and Integrative Health (NCCIH) says the fruit has been used as a tea in folk medicine for inflammation and stomach complaints, and the rind as a food preservative.

NIH's LiverTox database adds that the dried, smoked rind is used as a sour flavoring, especially in fish curries. The rind contains hydroxycitric acid (HCA) along with other compounds such as xanthones and benzophenones. LiverTox says the fruit is 10% to 30% HCA by weight, and extracts can contain 20% to 60%.

Does it work for weight loss?

QuestionWhat NCCIH and LiverTox say
Weight loss in peopleUnclear: modest effect in some studies, none in others
Appetite suppressionSeen in rats; not consistently found in people
Other usesLess research

HCA blocks an enzyme involved in making fat, called ATP citrate lyase. In rats, garcinia and HCA caused appetite suppression and weight loss. LiverTox says these effects have not been consistently found in human studies, and NCCIH says more research is needed to confirm any effect.

Garcinia is also a frequent ingredient in over-the-counter multi-ingredient weight loss products, which makes it hard to know what any one ingredient is doing.

Liver injury: the main safety concern

If you take garcinia and notice yellow skin or eyes, unusual fatigue or nausea, stop and see a doctor right away. LiverTox advises against restarting it after a reaction.

Other side effects and interactions

If you still want to try it

A safer way to use garcinia

The dried rind has a long culinary history as a sour flavoring and spice, especially in fish curries, and LiverTox says it has also been used in Ayurvedic medicine for digestive complaints and rheumatism. Using it as a spice is very different from taking concentrated extract capsules, which is where the liver reports come from.

What to look for when you buy

Single-ingredient garcinia cambogia capsules

Best for: Adults whose doctor has reviewed the liver and drug risks

A single-ingredient product that states HCA content avoids blends that LiverTox says sometimes contained other liver toxins.

Watch out: Rare but serious liver injury. Not with serotonin drugs. Stop for yellow skin, fatigue or nausea.

When to talk to a doctor: Talk with your doctor before taking garcinia cambogia, especially if you have liver disease, take antidepressants or other serotonin drugs or medicines that affect the liver, or are pregnant or breastfeeding.
