"Garcinia Cambogia is a dietary supplement that could stand on it's own even without the assistance of HCG." ~Dr. Zach
 
Each capsule contains:
Garcinia Cambogia: 1600mg (60% HCA)
Calcium: 80mg
Potassium: 80mg (electrolytes are extremely imortant for the catobolysm of stored fat)
 
HCA is (-)-hydroxycitrate, an organic compound obtained from the dried rind of the Brindall Berry Plant, which is native to India. This chemically unique compound has been studied extensively for its specific effect on inhibiting the conversion of excess carbohydrates into stored fat. As a result, the free carbohydtrates that are not immediatealy stored as fat work to regulate appetite by producing an insuline response which mimicks a feeling of satiety and fullness.
 
HCA, the active ingredient in Garcinia Cambogia, helps inhibits the metabolic enzyme in the body that is responsible for the conversion of carbohydrates into fat, thereby reducing fat accumulation and cholesterol production while playing a key role in increasing the formation of glycogen – An increase in available glycogen (immediate energy reserve) will result in diminished fuel/sugar cravings and reduces appetite. In short, Cambogia reduces fat accumulation while also reducing appetite.
