Tribulus Terrestris: Evidence & Safety

Tribulus is marketed for sexual function and testosterone. Human research is mixed. NCCIH summarizes one trial reporting improvement in sexual function and an earlier trial finding no advantage over placebo for ED symptoms or testosterone. A 2025 meta-analysis reported improvements in erectile-function scores across included trials, but that does not establish efficacy for every formulation or combination product.

How this connects to product research

Evidence for an individual ingredient does not prove that a finished multi-ingredient supplement produces the same outcome. Dose, extract, formulation and study population matter.
