Rating (out of 5): 1

Tribulus terrestris is commonly marketed as a natural supplement to enhance athletic performance, increase strength, and boost testosterone levels. Its use for these purposes is primarily based on anecdotal reports and preliminary studies, rather than robust scientific validation. Early animal studies suggested that Tribulus might increase androgen levels, but these findings have not been consistently replicated in humans. Several well-designed clinical trials in athletes and healthy men have found no significant effects on testosterone levels, muscle mass, or athletic performance compared to placebo. For example, a 2005 randomized controlled trial in trained male athletes found no performance or hormonal benefit from Tribulus supplementation. Similarly, a 2014 meta-analysis concluded that there is insufficient evidence to support its efficacy for improving exercise performance or body composition.

Despite its popularity in traditional medicine systems such as Ayurveda and Traditional Chinese Medicine (TCM) for treating various ailments, the specific use of Tribulus as an athletic or exercise aid appears largely driven by modern marketing. The evidence supporting its application in this context is weak, with most reputable sources and sports medicine organizations not recommending it due to lack of demonstrated benefit. In summary, while Tribulus terrestris is widely used as an athletic and exercise aid, the scientific evidence supporting such use is minimal, and its effectiveness remains unproven.
