Green Tea Extract- For thousands of years, Green Tea has been used for the purpose of medicine in countries such as China and India. The leaves of the Camellia Sinensis plant are allowed to dry after being lightly steamed. The leaves are steamed as the properties of the plant are retained through this procedure. The extract has a number of varying health benefits, inclusive of properties that assist the body in fighting cancer and body protecting antioxidant effects. Green tea also offers protection against digestive and respiratory infections. It reduces health affecting LDL cholesterol, increases the levels of HDL cholesterol that is good for the body. Along with keeping control of the content of blood sugar in the body, it also helps burn fat in the body by boosting the metabolic rates.

Guarana, a stimulant derived from the seeds of the Brazilian Guarana plant. Guarana is used to increase alertness and help fight fatigue. It contains caffeine and is usually associated with an "energy crash" several hours after taking a large dose.

L-Theanine is very commonly found in tea and is an amino acid, biochemically related to glutamine. The psychoactive properties of theanine are derived from the ability to cross the blood brain barrier. It has been proven that theanine can reduce stress, promote relaxation and improve alertness and mood when imbibed together with caffeine, a natural combination found in any tea, especially green tea. Gamma-aminobutyric acid levels are increased, when theanine is ingested or imbibed, as are serotonin and dopamine levels. It is believed that l-theanine is aiding the immune system by strengthening the capacity of delta T cells. Laboratory tests have proven that blood pressure reduction and lowering of 5-hydroxyindoles in the brain are promoted by theanine.

L-Tyrosine is a non-essential amino acid, which is used by the cells in order to synthesize the proteins and appears to help stabilize ones mood during periods of high stress levels.

Norambrolide, or fermented salvia sclarea leaf extract. Norambrolide is thought to increase cAMP (cyclic adenosine monophosphate) levels in the body through the stimulation of the "adenylate cyclase" (AC) enzyme. This stimulation is believed to help activate increased fat burning.

Vitamin B12, also known as cobalamin, which is naturally found in foods such as fish, milk and milk products, eggs, meat and poultry. Vitamin B12 is important for good health, necessary for the proper digestion and absorption of foods and for normal metabolism of carbohydrates, and fat. It helps maintain healthy nerve cells and red blood cells and is needed to make DNA. Vitamin B12 is bound to the protein in food. Hydrochloric acid in the stomach releases B12 from protein during digestion. Unlike other water-soluble nutrients, vitamin B12 is stored in the liver, kidney, and other body tissues. It can take several years before signs of the deficiency appear due to poor dietary intake. Vitamin B12 functions as a "methyl donor." A methyl donor is a compound that carries and donates methyl groups to other molecules, including cell membrane components and neurotransmitters. As a methyl donor vitamin B12 is involved in homocysteine metabolism and plays a critical role in proper energy metabolism, immune function, and nerve function. Therefore, vitamin B12 is clearly an added benefit for anyone wanting to lose weight, as without it, metabolism is not at its peak potential.

Yerba Matte- The plant of the yerba maté, as yerba matte is actually called, is a small tree or a shrub which can grow up to a size of fifteen meters. The leaves and twigs have traditionally been used to brew a tea like concoction, which is still a very popular social beverage in South America. Yerba maté contains alcaloids that are very similar to caffeine, commonly referred to as xanthines, but also elements like manganese, magnesium and potassium. The main difference between yerba maté and coffee, for instance, is the effect it has on muscle tissue, where it appears to relax smooth muscle tissue, but stimulate heart tissue and that is why it is used in Xenadrine NRG. In other studies, yerba maté was found to work as a monoamine oxidase inhibitor, thereby professing antidepressant qualities.
