Garcinia Cambogia 50% Extract
Whole Health MD Article: The herb Garcinia cambogia is rich in a substance called hydroxycitric acid, or HCA. Animal and test-tube studies indicate that HCA may promote weight loss in two basic ways. First, HCA seems to work in part by blocking the conversion of sugary foods and starches into fats. Put another way, this means HCA is believed to help inhibit fat production. Second, recent findings indicate that by raising levels of certain brain chemicals such as serotonin, a key regulator of appetite control, HCA also may suppress appetite.

Green Tea (Decaffeinated)
Acupuncture Today Dr. Abdul Dulloo led the research into weight loss, which was conducted at the University of Geneva . Dulloo's team studied the effects of green tea on ten healthy young men (average age: 25) who ranged in body type from "lean" to "mildly overweight." The study's participants were put on a "typical Western diet" of about 13% protein, 40% fat and 47% carbohydrates for six weeks. Three times during the study, researchers measured the men's energy expenditure (EE - the number of calories used in a 24-hour period) in a respiratory chamber. They also gauged the men's respiration quotient, or RQ. (RQ is a measurement of how well the body utilizes carbohydrates, proteins and fats. A lower RQ means that more fats are being metabolized by the body for energy.) Results showed that those men taking the green tea extract experienced "a significant increase in 24-h EE" and "a significant decrease in 24-h RQ" over those taking only caffeine or the placebo. Men taking the green tea extract also used more fat calories than those using the placebo. http://www.acupuncturetoday.com/archives/2000/feb/02greentea.html

Slimaluma
Slimaluma is a concentrated extract of Caralluma fimbriata. Caralluma fimbriata is an edible cactus, used by tribal Indians to suppress hunger and enhance endurance. Waist circumference and hunger levels over the observation period showed a significant decline in the experimental group when compared to the placebo group. Caralluma extract appears to suppress appetite, and reduce waist circumference when compared to placebo over a 2month period. A patented, tested extract of Caralluma fimbriata has been developed and standardized by a company called Gencor. Known as "Slimaluma," the extract delivers the plant in a concentrated form.

Chromium polynicotinate
Studies on chromium polynicotinate in rats have shown to prevent the sucrose-induced elevation of systolic blood pressure and decreases measures of lipid peroxidation. Studies show that this dietary supplement may provide benefits including weight loss, lowered serum cholesterol and glucose, burned fat, and build muscle.

Guggulsterones 2.5%
There are a lot of scientific studies that show guggulsterones. Carefully planned scientific studies show that guggulsterones are highly effective at accelerating fat loss, mainly due to their stimulating effect on the thyroid gland. The thyroid hormones are among the most important hormones. They control your metabolic rate, which dictates how many calories you burn each day. When your metabolic rate slows down, which it does when you go on a diet, you automatically burn fewer calories each day. This means that the rate at which you lose weight slows down. The website has all the scientific references and studies done on guggulsterones.
