Garcinia cambogia is a moderate-sized, evergreen tree found largely in the high rainfall areas. It bears sweet-sour mixed fruits native to SE Asia and India. The fruit is a small yellow or it may have a unique purple color. Since years, the fruit of Garcinia cambogia has been traditionally used in food preparation.
However, Garcinia has garnered a lot of attention of late as a popular natural weight loss aid. The reason is that the rind of this pumpkin like fruit is rich in a substance called hydroxycitric acid / HCA, a principle extract of Garcinia cambogia. Garcinia is a source for a revolutionary natural diet ingredient which is currently a rage in America, Japan, Europe, and other western countries.
The rind of the fruit is extracted in water medium and subsequently treated to achieve the desired percentage of HCA content. Studies worldwide has shown that the HCA discourages the fat storage and encourages calorie burning. The result is more energy and less bulk, and while HCA accelerates the breakdown and dispersal of fat already laid down, it also reduces excess cholesterol. HCA works best combined with chromium, an essential mineral which helps the body to control its blood sugar effectively - cutting sweet cravings.
Garcinia cambogia is available as a single agent and in combination with other herbals and minerals that are also thought to promote weight loss. Although dosing recommendations differ according to the manufacturer, commercial Garcinia cambogia products generally contain about 50% of HCA. Doses of HCA used in human studies have ranged from 250 mg three times a day to 1000 mg (one gram) three times a day. For weight loss, a Garcinia cambogia product is usually taken about half an hour before each meal.
