Tribulus Alatus Extract
Also known as: Tribulus Alatus, Puncture Vine, Gokshura, Tribulus, Tribulus Terrestris Extract, Tribulus terrestris
Overview
Tribulus terrestris is a flowering plant native to warm and tropical regions of the Old World, particularly used in traditional medicine and as a dietary supplement. It has garnered attention primarily for its potential effects on sexual function, testosterone levels, and athletic performance. The plant contains bioactive compounds such as saponins, flavonoids, and alkaloids. Despite its popularity, the current research presents mixed results, particularly regarding its effectiveness; while some studies indicate benefits in enhancing sexual function in women, the overall evidence quality is low, primarily due to methodological flaws such as limited sample sizes. Tribulus terrestris is available in various forms, including capsules and powders, making it accessible for dietary supplementation.
Benefits
The evidence-based benefits of Tribulus terrestris include limited increases in testosterone levels, especially when combined with other supplements. Some studies highlight its potential to enhance sexual function in premenopausal and postmenopausal women, although this evidence remains of very low certainty. Additionally, laboratory studies suggest possible antihypertensive effects and antioxidant and anti-inflammatory activities. However, effect sizes are generally small, raising questions about the clinical relevance of these findings. Improvements in athletic performance are also suggested, yet high-quality evidence supporting this claim is lacking.
How it works
Tribulus terrestris is thought to facilitate the release of nitric oxide, which promotes vasodilation, hence potentially improving sexual function. The plant's saponins may influence multiple biological pathways associated with inflammation and oxidative stress reduction. It is believed to interact positively with the cardiovascular system by relaxing arterial smooth muscle, possibly contributing to lower blood pressure. Nonetheless, data on absorption and bioavailability in humans remain scarce, necessitating further research to clarify its mechanisms of action.
Side effects
Despite a generally favorable safety profile for Tribulus terrestris, it warrants caution due to potential adverse effects, particularly at high doses or with extended use. Common side effects are not well documented, though gastrointestinal symptoms and allergic reactions have been noted. Rare incidents include elevated liver enzymes and mild hepatic alterations, with isolated severe cases such as hyperbilirubinemia, acute renal failure, and neurotoxicity, primarily under high doses. Additionally, there may be interactions with medications metabolized by P-glycoprotein, raising concerns for individuals with existing liver or kidney conditions. As such, monitoring liver and kidney function is advisable for users.
Dosage
There is currently no established minimum effective dosage for Tribulus terrestris; however, typical daily dosages range from 500 mg to 2000 mg. It is recommended to take the supplement with meals to potentially enhance absorption and effectiveness. While no definitive maximum safe dose is established, caution is advised for doses exceeding 2000 mg due to increased risks of adverse effects. For consistency in levels of bioactive compounds, standardized extracts of the herb are preferable to ensure uniformity in supplementation.
