Liquefied German Tribulus Terrestris
Also known as: Puncture Vine, Gokshura, Bindii, Tribulus terrestris
Overview
*Tribulus terrestris* is a flowering plant belonging to the Zygophyllaceae family, native to regions of Europe, Asia, and Africa. Its aerial parts and fruits are utilized in traditional forms of medicine, acclaimed for diuretic, tonic, and aphrodisiac benefits. Athletes often use this herb for its proposed ability to improve testosterone levels and enhance physical performance, though research findings are inconsistent. It contains bioactive compounds, especially furostanol saponins like protodioscin, which are believed to elicit various physiological effects. Although some benefits for health and performance have been noted, the overall research is of mixed quality, characterized by variability in study designs and dosage regimens.
Benefits
Research on *Tribulus terrestris* suggests minimal direct efficacy in boosting testosterone levels among humans, yet it can potentially improve lipid profiles and some hematological markers, notably in physically active individuals. A systematic review indicates significant enhancements in lipid measures and moderate benefits on inflammatory and hematological markers. Furthermore, a meta-analysis revealed positive effects on male fertility indicators (e.g., sperm concentration and motility) and erectile function, with moderate effect sizes noted. Nevertheless, the evidence remains limited, necessitating further comprehensive studies to reinforce these findings.
How it works
The exact working mechanism of *Tribulus terrestris* is not fully elucidated. It may promote nitric oxide release, contributing to improved vascular health and potentially enhancing erectile function. The active compound, protodioscin, is believed to influence several biological pathways, which might include antioxidant effects and anti-inflammatory activity, likely enhancing overall physiological responses. Additionally, the interactions with the cardiovascular and reproductive systems could elucidate its purported benefits.
Side effects
*Tribulus terrestris* is generally deemed safe when used appropriately, with no major toxicities recorded in available literature. Common adverse effects are poorly reported, but no significant frequent side effects were identified in studies. Uncommon and rare side effects remain undocumented. While specific drug interactions are not established, users should consult healthcare professionals if concurrent medications are in use. Pregnant and breastfeeding women are advised to avoid this supplement due to a lack of safety studies. Generally, users should be cautious and seek advice if underlying health conditions exist.
Dosage
Dosage guidelines for *Tribulus terrestris* are not concretely defined, but common recommendations range from 500 mg to 2000 mg of dried extract daily. Generally, the formulation is consumed in divided doses to optimize effects. Taking it with meals may enhance absorption. There is no universally accepted upper limit, and doses up to 2000 mg daily have shown no reported adverse effects, but individual recommendations may vary based on specific health considerations.
