Other Proposed Uses
Hydroxycitric acid (HCA), a derivative of citric acid, is found primarily in a small, sweet, purple fruit called the Malabar tamarind or, as it is most commonly called, Garcinia cambogia . Test tube and animal research suggests that HCA may be helpful in weight loss because of its effects on metabolism. However, studies in humans have found mixed results.
HCA is not an essential nutrient. The Malabar tamarind is the only practical source of this supplement.
A typical dosage of HCA is 250 to 1,000 mg 3 times daily. Supplements are available in many forms, including tablets, capsules, powders, and even snack bars. Products are often labeled Garcinia cambogia and standardized to contain a fixed percentage of HCA. Various proprietary forms of HCA are also available, often claimed by their promoters to be more effective.
What Is the Scientific Evidence for Hydroxycitric Acid?
It remains unclear whether HCA offers any weight-loss benefits.
