Hydroxyl citric acid (HCA) is the element that imparts tartness to Garcinia Cambogia or commonly known as the Malabar tamarind. This tropical fruit is one of the major sources of the derivative of citric acid and can substitute any other dietary needs of tartness in foods. Some traditional South Indian and South Asian cuisines still use this fruit to add zing to the recipe.
HCA is believed to be a fat burner because it plays a role in conversion of fatty acids to lipids and thereby lowers fat production. Therefore bad cholesterol (LDL) is also produced at lower rate, a major trigger for heart diseases. Another chemical ingredient known as Garcinol is also present in this fruit. This is a natural anti-biotic sans any side effects of using a pharmaceutical antibiotic drug. The zing of the fruit is from citric acid compounds which are rich in vitamin C and other B complex vitamins.
