How It Works


Caffeine is a central nervous system (CNS) stimulant that enhances and prolongs thermogenesis. The mechanism in which caffeine enhances the thermogenic process is by inhibiting the release of phosphodiesterase. Why is this important? Well let's look.

The Lean-FX increases noradrenaline (NA) which in turn increases thermogenesis through Beta-1, 2 and 3 adrenergic receptors. Caffeine synergistically enhances the effect of ephedrine by blocking phosphodiesterase. Phosphodiesterase (PDE) inhibits the release of noradrenaline-induced cAMP. NA-induced cAMP cAMP acts as a messenger in the cascade of thermogenic activity induced by Lean-FX. If NA is not produced or is inhibited then the message never gets sent, thus ceasing thermogenesis. In studies a specific ratio of ephedrine and caffeine exerted a supra-additive synergism, whereas the thermogenic effects of lower doses of caffeine only had an additive effect.


Geen Tea Extract is a natural ingredient from the leaf of the tea plant, Camellia sinensis. Usage shows green tea causes a significant increase in 24-hour energy expenditure and enhanced fat-oxidation. In fact, effects were significantly greater than a group receiving only caffeine.

Scientific data supports the idea that the polyphenol/catechins in green tea act on the sympathetic nervous system and adrenal glands to increase calorie expenditure and fat burning. Green tea also appears to inhibit the fat-digesting enzymes in the stomach, suggesting an obvious reduction in fat digestion and absorption. Green tea is the second-most consumed beverage in the world and has been used medicinally for centuries in India and China. Check out more about Green Tea Here


Lean-FX is very similar in response to ephedrine. But has a much milder stimulant effect. Lean-FXs thermogenic activity is mediated by activating the Beta-3AR located in brown fat. The selective release of noradrenaline and adrenaline in the beta-3 receptor site does not cross the blood-brain barrier, which allows an increase in metabolic rate without affecting heart rate or blood pressure. Increasing oxygen uptake only further increases the efficiency of thermogenesis.


L-Tyrosine has many synergistic functions in this fat loss arsenal. It is a precursor to the thyroid hormone T3, neurotransmitters adrenaline,
noradrenaline (NA), and dopamine. Not only does tyrosine aid thyroid function but most importantly it maximizes the efficiency of NA. Tyrosine adds to the arsenal of ingredients in Lean-FX that optimize NA production and thermogenesis.


Research indicates that ginger (particularly the gingerol contained therein) is highly thermogenic. The mechanism of action seems to be that ginger induces the muscle tissue to consume more oxygen which is necessary for burning fat as a source of energy fuel. Likewise, cayenne's constituents have been shown to have thermogenic properties, as well as effecting metabolic rate.


Lean FX has been designed to be one of the most potent and effective fat loss aids on the market by combining ingredients that are proven to not only work effectively by themselves but to synergistically enhance the traditional Caffeine stack. Caffeine and Ginger inhibit enzymes that block noradrenaline. Lean-FX directly targets beta-3 adrenergic receptors to stimulate brown fat thermogenesis. L-tyrosine not only regulates thyroid but also provides the precursor to noradrenaline that is ultimately stimulated by Ephedrine. As you can see, Lean FX was designed to comprehensively target the entire thermogenic process.
