New and Improved, Extra-Strength Xenadrine EFX is a potent ephedra free, thermogenic fat burner and lipolysis stimulator, proven to help break down fat. This revolutionary formula contains a powerful blend of natural ingredients shown in clinical research to increase the body’s metabolic rate and support the burning of body fat.

Original Xenadrine EFX was the first scientifically based, ephedra free thermogenic (heat producing which leads to the body burning more calories) formula been shown to be truly effective in product specific clinical research. Now, New and Improved, Extra-Strength Xenadrine EFX is even better with the addition of Norambrolide™. This fermented sage compound has been shown in unpublished in-vitro research to increase levels of a cellular messenger called cAMP (cyclic adenosine monophosphate). The significance of this is that in some metabolic processes, cAMP is involved in activating cellular enzymes and other substances that help move fat out of the fat cells and promote the weight loss process; although no research has yet been done to demonstrate that Norambrolide™ will have this effect in humans. However, unpublished in-vitro research has shown that Norambrolide™ was successful at increasing lipolysis (the breakdown of fat) by 11-24%. Of course New and Improved, Extra-Strength Xenadrine EFX still provides all of the proven ingredients of the original formulation which was shown in clinical research to substantially increase resting energy expenditure and metabolic rate. These ingredients include green tea extract, which has been demonstrated in a randomized, placebo-controlled study to increase weight loss and burn calories. Other research on green tea has shown similar results. New and Improved, Extra-Strength Xenadrine EFX also contains bitter theobroma cacoa extract, a source theobromine. Theobromine and other related methylxanthines (e.g., caffeine) have been identified as having thermogenic activity in double-blind human and animal research. This advanced formula also contains Tyroplex™ and Isotherm™. Tyroplex™ is a proprietary blend of l-tyrosine and acetyl-l-tyrosine. Tyrosine is a precursor to catecholamines like norepinephrine and dopamine , which are integral to the body’s fat burning processes. Isotherm™ is a combination of the naturally-occurring flavones 3,3',4',5-7 pentahydroxyflavone (PF) and 3,3',4',7-tetrahydroxyflavone (TF). In in-vitro research both PF and TF9 11 have been shown to increase lipolysis (the breakdown of fat) and stimulate cyclic AMP accumulation. Rounding out this formula are vitamins C, B6, Pantothenic acid, Magnesium, and grape seed extract.
