Green tea Extract
Green tea is produced from the Camellia sinensis plant. To manufacture green tea, the leaves of this plant are picked and heated rapidly to inactivate enzymes and to prevent fermentation.
Green tea contains a number of different chemicals called polyphenols, such as flavonols, flavonoids and phenolic acid. Flavonols, which are also known as catechins, are the most important polyphenols that occur in green tea. The most important flavonol is called epigallocatechin gallate or EGCG.
According to a study published in the American Journal of Clinical Nutrition, Green Tea Extract accelerates calorie burning through increased thermogenesis, particularly with fat calories. Researchers at the University of Geneva came to this same conclusion after a 10-week study showing significant weight loss in the test subjects.

Dandelion Root
Stimulates digestive functions and is considered an excellent cleansing tonic for the liver
Dandelion root is regarded as a "liver tonic", which has led to its use for many illnesses traditionally believed to be caused by a "sluggish" or "congested" liver, including constipation, headaches, eye problems, gout, skin problems, fatigue and boils.

Building on this traditional thinking, some modern naturopathic physicians believe tht dandelion can help "detoxify" or clean out the liver and gallbladder. This concept has led to the suggestion that dandelion can reduce the side effects of medications processed by the liver, as well as relieve symptoms of diseases in which impaired liver function plays a role.
Dandelion root is also used like other bitter herbs to improve appetite and treat minor digestive disorders.

Garcina Cambogia
Garcina Cambogia Extract, also known as Citrimax, contains 50% hydroxycitric acid (HCA) which works with the body's own natural use of calories. It suppresses appetite by redirecting calories away from fat production and towards the formation of glycogen. Glycogen is the stored form of glucose, one of the body's primary sources of energy. Increased glycogen production and storage is the body's normal way of signaling the brain's satiety centre that enough food has been eaten. HCA is not a central nervous system stimulant. HCA is most effective at influencing appetite, increasing energy levels and inhibiting fat and cholesterol production

Guarana
Guarana (pronounced gwa-ra-NAH) is a creeping shrub native to Venezuela and northern Brazil in the Amazon rain forest. The fruit are small, bright-red, and contains black seeds.Guaraná is reputed to be a stimulant and increase mental alertness, fight fatigue, and increase stamina and physical endurance.

Evidence indicates that guarana may suppress appetite and increase fat-burning.

5-HTP
5-HTP or 5-Hydroxytryptophan, is a metabolite of the amino acid tryptophan. 5-HTP is similar to tryptophan in that the body converts them to serotonin. Serotonin has many important roles in our body such as improving mental function, helping our bodies relax, and regulating sleep and mood

The diet and exercise folks might be thinking ‘This is great, but what will it benefit me to supplement my diet with 5-HTP?’ Well, 5-HTP helps to suppress your cravings for carbs and is used to control your appetite.

5-HTP is a terrific supplement found in effective weight loss products.

Chitosan
This dietary supplement is made from chitin, a starch found in the skeleton of shrimp, crab, and other shellfish. Chitosan isn't digested, therefore it passes through your intestinal tract unabsorbed without adding any calories. The chemical nature of Chitosan makes it bind with fatty foods, removing some of the fat from your body rather than allowing it to be absorbed. One study, however, found significant more weight loss from Chitosan than from a placebo.

Gingseng
American research suggests a scientific basis for the use of ginseng as a general body tonic.

Ginseng has been shown to increase work efficiency by raising capacity for mental and physical performance and allowing for better adaptation to high and low temperatures. Ginseng increases tolerance to stress. Its effect is termed adaptogenic. The life of X-ray-irradiated mice has been prolonged with ginseng. It also counteracts the toxic effects of chemicals such as choloroform and amphetamines.

In Chinese medicine, ginseng is combined with other herbs to treat a wide range of illnesses. Future research may provide important new applications for ginseng in disease prevention and cures.
