How Xtralean Ephedra ECA stack works:
The effects of the ECA Stack (ephedra, caffeine aspirin) in XtraLean are enhanced by a unique combination of supporting herbs and compounds in precise ratio.
Synephrine - The newest thermogenic component along with Ma Huang and guarana provide broad spectrum ephedrine and methylxanthine alkaloids which maximize the energy-boosting properties of this exceptional formula.
3,7,3'4'-Tetrahydroxyflavone - This powerful synergist is proven to further enhance the effects of the ECA Stack causing even greater increases in adrenal hormones epinephrine and norepinephrine. Thermogenic effects and performance-enhancing effects are dependent on these hormones by their binding to alpha and beta adrenergic receptors in muscle and fat cells.
DMAE (2-dimethylaminoethanol) - This potent acetylcholine precursor is added to assist mental functioning thus promoting higer exercise intensity and motivation as well as assisting liver production of choline thus helping to process more fat.
Acetyl-L-Carnitine - This amino compound is essential for the transport of fats into the very heart of the cells fat burning mechanism. It is also shown in numerous studies to enhance nervous system function.
L-Tyrosine - This essential amino acid play a vital role in nerve function and acts to minimize nerve sensitivity to the stimulating effects of ephedrine and caffeine which some people find undersireable, yet still want to have the potent fat-burning effects. Pantothenic acid (B-5) and Magnesium phosphate also aids nerve function.
Ginger - Ginger enhances all other ingredients due to enhanced circulation. It also helps digestion and reduces stomach upset.
