Garcinia Cambogia is a small fruit that looks just like a small size pumpkin. An extract from its fruit and rind has been used to prepare various products mainly for weight loss. This herb, which is mainly found in India and some parts of Asia, is believed to suppress appetite and enhance fat-burning due to the presence of hydroxycitric acid (HCA) in the extract. This is how it works - HCA inhibits an enzyme called citrate lyase that plays an important part in converting excess carbohydrates into fat, but when it is inhibited, the body burns the extra carbs. While animal studies have suggested reduced food intake and decrease in body fat, human trials have not been so conclusive.

Green Tea Extract is a widely consumed beverage in the world. It is well known for its antioxidant properties. It is traditionally used to treat ailments such as headaches, poor digestion, and body aches. Green tea extract is rich in catechin which increases the level of cholecystokinin that suppresses that appetite, thus promoting weight loss. It also contains Pheophytins, chlorophylls, caffeine, and carotenoids that have anti-genotoxic and antioxidant properties.

Gymnema Sylvestre is native to India, predominantly in tropical forests of India. This herb has traditionally been used in the Indian eclectic alternative medical system as the naturopathic treatment for diabetes. The active ingredients or bioactive constituents are a group of gymnemic acids, which have antidiabetic and anti-inflammatory as well as antisweetener properties. If used for a while, gymnema sylvestre, or rather the gymnemic acids, have the effect of reducing the blood sugar level. These glycosides are found in an extract of the leaves and it seems that the acids have a similar structure to saccharose. Besides the gymnemic acids, the plant contains also saponins, quercitol, stigmasterol and also some amino acid derivatives, namely trimethylamine, betaine and choline. When the leaves of gymnema sylvestre are chewed, you temporarily lose the ability to taste sugar.

Hoodia Gordonii is widely thought of as an appetite suppressant; however, there have not been sufficient studies to support this theory.
