Tribulus Seed Extract
Also known as: Tribulus, Gokshura, Puncture Vine, Tribulus terrestris
Overview
*Tribulus terrestris* is a perennial plant native to tropical and temperate regions that has been used in traditional Ayurvedic and Chinese medicine for its alleged health benefits, particularly related to enhancing male reproductive health. It contains a variety of bioactive compounds, notably saponins and flavonoids, believed to contribute to its purported pharmaceutical properties. While it is frequently marketed for boosting libido, male fertility, and addressing erectile dysfunction, the scientific evidence remains mixed, with systematic reviews indicating that while some studies present promising results, the overall quality of research does not robustly support all the health claims associated with this supplement.
Benefits
Research indicates that *Tribulus terrestris* may significantly enhance male fertility, specifically improving sperm concentration and motility. A meta-analysis showed a standardized mean difference for sperm concentration of 0.624 (95% CI: 0.13 to 1.117, p = 0.013) and for motility of 0.742 (95% CI: 0.331 to 1.152, p = 0.001). While some evidence suggests potential benefits for erectile dysfunction, these findings are inconsistent, and further validation is needed. Overall, the benefits appear most pronounced in male populations focusing on fertility enhancement, but the clinical significance of these effects is still under scrutiny, requiring more substantial evidence.
How it works
*Tribulus terrestris* is thought to enhance nitric oxide production, which may facilitate vasodilation and improve blood flow, thereby positively influencing sexual function. Additionally, this herb may influence hormone levels, including testosterone, although the exact biological pathways and molecular targets remain largely undefined. Its components, particularly saponins, are believed to play a significant role in these effects, potentially interacting with various body systems, especially the reproductive and cardiovascular systems.
Side effects
The safety profile of *Tribulus terrestris* is generally considered favorable when used as directed, although comprehensive documentation on adverse effects is limited. Possible gastrointestinal disturbances occur in a small percentage of users (<5%), while other side effects are not well recorded. There are potential interactions with certain medications, particularly blood thinners and diabetes medications, and its use is not recommended during pregnancy or breastfeeding due to insufficient safety data. Additionally, caution is advised for individuals suffering from diabetes or bleeding disorders, as the effects of the herb on blood sugar levels and clotting parameters are not extensively studied.
Dosage
The recommended dosage of *Tribulus terrestris* typically ranges from 500-1000 mg per day. However, precise minimum effective doses are not well defined, and there are no specific timing guidelines associated with its intake. Common forms of supplementation include capsules and extracts. Despite a lack of exhaustive data on absorption factors, users should exercise caution with dosage, as maximum safe limits remain unclear.
