Citrus Aurantium is the Latin name for a citrus tree which grows bitter oranges. Traditionally being used by Chinese medicine and herbologists, the extract of the orange and the peel was used as a dietary supplement in concoctions with other herbs to suppress appetite. While other active ingredients of the citrus aurantium may contribute and even promote the effect, the main ingredient used in all weight loss products is synephrine, an alkaloid similar to ephedrine. It is a phenethylamine; it influences the alpha1 adrenergic receptor, constricting blood vessels, additionally increasing the heart rate and the blood pressure. In most cases the use of synephrine is paired with a diet and body building plan, where weight loss and muscle building is essential.

Green Tea Extract increases energy expenditure and affects fat oxidation, which therefore promotes weight loss by increasing the body's metabolism.
