Garcinia Cambogia Fruit Extract is an extract of the fruit of the Gamboge Tree, Garcinia cambogia, Guttiferae. Garcinia Cambogia (Malabar Tamarind) is a small fruit that has some traditional usage to enhance the culinary experience of a meal, but beyond that has limited medicinal usage. It is a very good source of hydroxycitric acids (structurally related to citric acid, a sour flavorant) and one of the isomers, known as (-)-Hydroxycitric acid, is thought to help in weight control. Several studies have shown that Garcinia cambogia plays an important role in the regulation of endogenous lipid biosynthesis. This effect is specially attributed to (-)-hydroxycitric acid (HCA) inhibiting the enzyme ATP-dependent citrate lyase, which catalyzes the cleavage of citrate to oxaloacetate and acetyl-CoA. Studies conducted in experimental animals have not reported increased mortality or significant toxicity. Furthermore, at the doses usually administered, no differences have been reported in terms of side effects or adverse events (those studied) in humans between individuals treated with G. cambogia and controls.
