Chromium Polynicotinate, which is a form of chromium, an essential trace mineral that is needed for the body's production of insulin. Insulin is a hormone that stabilizes the body's blood sugar level.

Garcinia Cambogia, which is used for the active ingredient, Hydrocitric Acid or HCA. It is extracted from the garcinia cambogia fruit, similar to an orange. It is commonly used as an appetite suppressant. Hydrocitric acid or HCA is a "lipogenesis inhibitor," which means that it slows down the production of fat from the metabolism of carbohydrates and proteins. This means that more calories are burned as energy and less are turned into stored fat. Studies on animals and humans have shown that HCA can suppress fat production and reduce appetite.

Guarana is a South American climbing plant belonging to the genus of trees and shrubs called Maple. This plant is common around the Amazon and very present in Brazil. The fruit of the guarana plant is being used in that country to produce a diversity of soft drinks and beverages, having the double caffeine content of the coffee bean. Other nutrients that are contained in the seed besides caffeine are protein, fat and starch, but also adenine, choline, guanine, resin, tannin and xanthine, just to name a few. The cognitive effects of guarana are well documented, but the appetite suppressant qualities of guarana are relatively new. A study has proven that a combination of yerba mate, guarana and damiana leads to a tenfold weight loss quantity when compared with a placebo.

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

Synthetic Guggulsterones, which is a form of orally administered guggulipid, which increases T3 (tryiidothyronine) levels in animal models. T3 is the conversion product of T4, which is produced by the thyroid gland. Thyroid hormone levels are closely involved in metabolic function. Increased thyroid levels can cause more fat to be burned and stored. While on a diet, the body responds by decreasing T3 levels, therefor decreasing metabolic rate. It is not known how guggulipid increases T3 levels. Guggul, also called guggulipid, is an ethyl acetate extract of the gum resin of the guggul tree.
