Tribulus Terrestris

Tribulus is a vine that has been used as a general energy tonic and herbal treatment for impotence, it is found primarily in sports supplements for bodybuilders and weight lifters looking to increase testosterone.

Tribulus is known to raise blood levels of the Luteinizing hormone which indirectly results in an increase in testosterone.  LH is produced by the pituitary gland and one of its roles in the body is to balance testosterone.

Scientific studies- The main active ingredient in Tribulus is not known, but is thought to be a component called furostanol saponins.  There hasn’t been much research done on Tribulus suggesting that it causes a rise in testosterone like many Bodybuilding magazines and websites suggest.  Some european studies suggest that Tribulus can cause a raise in testosterone by 30-50%.
