Both Garcinia cambogia and the extracted acid HCA are widely used in weight control formulas. HCA inhibits the formation of fatty acids and therefore less fat is available to the cells to be stored by the body. HCA also reduces appetite according to studies.
Over-the-counter weight loss supplements for weight control usually offer HCA in dosages of 250 to 1,000 mg 3 times daily. HCA is available in many forms, including capsules, powders, tablets, and even snack bars. Products are often labeled Garcinia cambogia and standardized to contain a fixed percentage of HCA. Why use the whole fruit? What garcinia fruit offers that HCA supplements do not is potassium. The HCA in supplements is bound to calcium and is poorly absorbed.
