Effex Tribulus [Tribulus Terrestris Extract]


Effex Tribulus is a herbal drug based on tribulus terrestris stem and leaves extract containing steroid saponins. It has a tonic effect and it stimulates the reproductive system functions. 

The studies show that the plant’s compound protodioscin is metabolized in the body to dehydroepiandrosterone (DHEA), which has a beneficial effect on the immune system, cell membrane integrity, erectile function and cholesterol metabolism. Cholesterol is known to be essential for the synthesis of all steroids, including DHEA, testosterone and estradiol, which explains the hypolipidemic effect of the drug. Other saponin components of the plant enhance the effect of protodioscin. The research showed the effect of a hydroalcoholic extract of tribulus terrestris on serum glucose and lipid profile of women with diabetes mellitus.
