HCA (hydroxycitric acid) is a close relative of citric acid, the agent that gives citrus fruits their characteristic tart flavor. HCA is obtained as a 50% standardized extract of Garcinia cambogia, a small fruit from southern India, where it has been used for centuries as a food preservative, flavoring agent, and digestive aid.
HCA exerts its weight control effect through its inhibition of the enzyme ATP citrate lyase, playing a critical role in energy storage.1 When calorie intake exceeds the body's energy needs, the excess glucose is converted into glycogen, which is stored in the liver and muscles for future conversion into energy. Weight gain occurs after the body's capacity for glycogen storage is reached. At this point, glucose from excessive calorie intake is converted into acetyl coenzyme A via a metabolic pathway involving ATP-citrate lyase and then into fat molecules, which are stored in fat cells. HCA has been shown to bind to ATP-citrate lyase to reduce the production of acetyl coenzyme A and also increase the ability of the liver and muscles to synthesize and store glycogen.2
Research has shown that HCA is absorbed with blood levels of HCA peaking two hours after ingestion and remaining in the blood for between four and nine hours after ingestion.3,4
