HealthViva Pure Herbs Garcinia is a natural, vegetarian weight loss supplement. The capsules contain extracts of Garcinia Cambogia fruit, also known as Malabar Tamarind in India and South East Asia. The active ingredient in garcinia cambogia has been identified: hydroxycitric acid HCA. Several scientific studies have found that HCA inhibits the synthesis of certain enzymes that are responsible for the conversion of extra carbohydrates into fats. This makes the spare carbohydrates available to be metabolized for energy. Garcinia also suppresses your appetite by making you feel full. Additionally, it decreases belly fat, controls emotional eating and increases lean muscle mass.
