Tribulus Terrestris

Last Updated: November 18 2022

Tribulus terrestris is a plant from Ayurveda where the root and fruits are used for male virility and general vitality, respectively. The roots enhance libido and sexual well being without affecting testosterone while the fruits appear to be potently protective of organ function.

Tribulus Terrestris is most often used for


Tribulus terrestris is a herb from Ayurveda that is mostly recommended for male health including virility and vitality, and specifically more catered towards cardiovascular and urogenital health. It is a common supplement for its libido enhancing properties and supposed testosterone boosting properties.

On the sexual side of things, tribulus does appear to be a relatively reliable and potent libido enhancer in rats and the lone human study assessing this has confirmed an increase in sexual well being and erectile function. While it is not exactly known how tribulus works, it is known to enhance androgen receptor density in the brain (muscle tissue not confirmed) which may enhance the libido enhancing properties of androgens. Limited evidence suggests that it is weak to non-effective in enhancing fertility.

A specific component, tribulosin, appears to be quite potently cardioprotective and is effective in the 1-10nM range. It has not yet been tested in living creatures, but remains a very promising option.

In animal research, the fruits of tribulus appears to protect the organs (mostly liver and kidneys) from oxidative damages at reasonably low dosages and also exert anti-stress effects; confirming the status of tribulus terrestris as an adaptogen.

Despite the above promise as an adaptogen and a libido enhancer, studies investigating tribulus in sports performance have all failed to find benefits. The herb seems to be a possibly healthy herb that enhances sexuality but with limited use for power output and testosterone enhancement (which it has repeatedly failed to do).

What else is Tribulus Terrestris known as?
Note that Tribulus Terrestris is also known as:
  • Trib

Dosage information

If rodent research applies to humans, then the dosage of 5mg/kg of tribulus terrestris saponins should be effective.

Traditional dosages of the basic root powder are in the 5-6g range while the fruits are in the 2-3g range.
