What is Tribulus Terrestris?

Tribulus Terrestris is an over-the-counter supplement commonly marketed for increasing testosterone and enhancing fitness. Research on its effectiveness is mixed. According to Andrew Huberman, some studies found that it can increase free and bio-available testosterone in certain populations, like postmenopausal women, although total testosterone did not reach statistical significance. Additionally, there is evidence suggesting Tribulus may improve measures of sexual desire and function in women experiencing a loss of libido. However, the results are variable and more research is needed to confirm its effectiveness consistently 1.

For males and females, the dosage in studies that showed an impact ranged from 750 milligrams daily, divided into three doses, to 6 grams per day over various periods 1.
