5) Tribulus Improves Insulin Levels

Compounds in Tribulus can help reduce diabetic effects. Tribulus reduces blood glucose levels while improving insulin levels in mice after 8 weeks of treatment (R).

6) Tribulus May Increase Libido

Tribulus supplementation can increase sperm count in men with oligozoospermia (low sperm count). It also found that Tribulus supplementation induced an improvement in erectile properties (R).


  • There is a gradual decrease in systolic blood pressure in both the drug treated groups A and B from the and of the 1st weeks of therapy (R).
  • The decrease of serum cholesterol was also observed in both the drug treated groups. However, the effect was more pronounced in Group A (10.23;<0.01) (R).
  • Pre-treatment with RGT and imipramine significantly reduced the immobility duration of mice in comparison to control group. However, in comparison to vehicle control, RGT non-significantly reduced the immobility duration (R).
  • After the pretreatment of 100 mg x L(-1) GSTT, compared with the H2O2 group, GSTT decreased the apoptotic percentage in cardiocytes damaged by H2O2 (P < 0.01) (R).
  • Moreover, the saponin attenuated the apoptosis in cardiocyte in response to NaCN (R).


If used for libido or erectile dysfunction reasons, take 6g of Tribulus root twice daily (before food in the morning and at night) (R)

If used for hypertension, take 3g of Tribulus fruit and aerial parts in the morning before food (R).


Athletes and bodybuilders use Tribulus because they believe it increases testosterone concentrations. However, evidence supporting such claims are lackluster. Multiple trials carried out with control groups revealed that taking Tribulus alone had no effect on testosterone levels in humans (RR).

Although Tribulus is widely marketed as a solution for sexual dysfunctions and infertility, such claims are unsubstantiated. It seems that sperm count and quality did not vary significantly between the control group and the experimental group. In a double-blind, placebo-controlled study, the Tribulus granules failed to significantly outperform the placebo (R).

Long term use does not show any major side effects (R).
