Only Natural uses the finest quality Garcinia Cambogia Extract providing 60% Hydroxycitric Acid in the production process and is filled in an easy to swallow vegetarian capsule. Developing research suggests that Garcinia might prevent fat storage and control appetite; however, whether these effects occur in humans is unclear. Garcinia Cambogia is a fruit typically found in Indonesia, India, Southeast Asia and West & Central Africa. Shaped like a small green pumpkin, it has been used for cooking and flavor. The natural extract of the garcinia cambogia rind is called hydroxycitric acid (HCA), and researchers claim that HCA can assist in weight loss. The HCA extract from Garcinia Cambogia supplement may aid in weight loss by helping block fat and suppressing appetite. HCA blocks fat by inhibiting Citrate lyase, a key enzyme that your body needs to make fat from carbohydrates. Usually carbohydrates or sugars that are not used immediately or stored in other forms are converted into fats. When HCA inhibits citrate lyase, the fat-making process is stopped and the production of LDL (bad cholesterol) and triglycerides decrease. HCA also suppresses appetite by increasing serotonin levels, which is a neurotransmitter in your brain that makes you feel good. Having low levels of serotonin may make you feel depressed or anxious, which may promote emotional or over reactive eating. In turn, when HCA is increased, serotonin levels are increased, which improves mood and suppresses the drive to react to stressful situations with food. As you eat less, your body senses this and it releases stored fat in your fat cells.
