The green tea extract may play a role in the control of body composition via the activation of thermogenesis & fat oxidation. Green Tea contains catechin-polyphenols & caffeine. The catechin-polyphenols inhibit the enzyme that tums off catecholamine activity. Catecholamines are responsible for the promotion of fat buming. The caffeine works to promote catecholamine production & also inhibit the enzyme phosphodiesterase. So this means caffeine has the enhanced ability to burn fatty acids due to the catechinpolyphenols & can act as an inhibitor of the phosphodiesterase enzyme, which turns off fat burning.

Synephrine Citrus Aurantium (Advantra-Zú ):

Is a Chinese fruit that contains several alkaloids with Synephrine being the principal compound. Synephrine is a related cousin of Ephedrine & according to its patent information, it does not act in the body as a stimulant. Synephrine is thought to only stimulate the beta 3 receptors, which control basal metabolic rate. This compound may provide the same fat burning, muscle sparing & appetite regulation as Ephedrine but with out any stimulant like side effects.

L-Tyrosine:

The amino acid L-tyrosine is converted to noradrenaline, which is one of the catecholeamines released by caffeine. The L-tyrosine conversion to noradrenaline causes catecholeamine rejuvenation & prolongs caffeine effectiveness. L-tyrosine is an amino acid that has been shown to enhance the effects of other thermogenic agents.

Forskolin:

The newest ingredient to enter the fat loss arena is Forslean or the Aurvedic herbal Forskolin standardized at 20% Coleus forskohlii. Research shows oral forskolin to be a potent stimulator of adenyl cyclase. Adenyl Cyclase is the controlling agent of fatty acid beta-oxidation or to put it simply when this enzyme is produced it forces the body to burn fat for energy or fuel. If this herb is combined with any beta-agonist say like synephrine it causes a supercharged release of fatty acids to be utilized for energy or fuel.
