Dr. Elizabeth's Extra Strength Garcina Cambogia is a safe, and all natural supplement for your weigh management. Garcinia Cambogia is a small fruit from southern India, where it has been used for centuries as a food preservative, flavoring agent, and digestive aid. The HCA extract from Garcinia Cambogia supplement aids in weight loss by doing two things: It helps to block fat, and it suppresses your appetite. Usually unused carbohydrate or sugars are converted into fats and deposited in the body. HCA(Hydroxycitric Acid) found in Garcinia Cambogia prevents formation of fat by blocking a key enzyme(Citrate lyase) that your body needs to make fat from unused energy. When HCA inhibits Citrate lyase, the fat-making process is halted, and your body breaks down the stored fat cells, resulting in increased metabolism and fat burning.
