- Source
- Fruit of the Tribulus terrestris plant (puncture vine)
- Role in the formula
- The sole active ingredient in Bulgarian Tribulus, and included in VIRON PRO's botanical blend.
- Available research
- Tribulus has been studied in a range of small human trials and reviews. Findings vary by extract, dose, population and outcome measured.
- Limitations of the evidence
- Many studies are small or short in duration, and results have been mixed. Research on an isolated ingredient does not prove the effect of a finished product.
