Garcinia cambogia, also called the Malabar tamarind, is a fruit that grows in Southeast Asia. This small, purple fruit is the primary natural source of hydroxycitric acid, which is a derivative of citric acid.

However, clinical trials on humans have produced mixed results and no definitive conclusions that support the weight-loss claims of supplements containing garcinia cambogia and HCA. Positive weight-loss and fat-burning effects have only been observable in the short term without long-term substantiation.

A typical dose of HCA is 250 to 1,000 milligrams three times each day. As of 2014, an article in Critical Reviews in Food Science and Nutrition notes that no serious side effects have been reported in healthy adults as a result of taking supplements that use either the fruit extract or the chemical concentration within this dosage range.
