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.hat Is the Scientific Evidence for Hydroxycitric Acid? It remains unclear whether HCA offers any weight-loss benefits. In an 8-week double-blind, placebo-controlled trial of 60 overweight individuals, use of HCA at a dose of 440 mg 3 times daily produced significant weight loss as compared to placebo.
An added benefit is its ability to decrease appetite. An important factor to consider when choosing a hydroxycitric acid supplement is the purity of the Garcinia Cambogia Extract. A study published in Current Therapeutic Research found that a 60 percent ratio of HCA aids in significant weight loss.hen humans metabolize carbohydrates, citric acid is one of the substances involved; hydroxycitric acid is a modified form of the acid. Basically, it inhibits the enzyme that turns carbohydrates into fat. Sugar is normally absorbed in 20 minutes, but with the presence of HCA, it takes more than 2 hours.
