The Active Ingredient Is: Tribulus terrestris extract (Standardised to 20% steroidal saponins)

Tribulus terrestris extract is a natural ingredient containing bioactive saponins that are linked with supporting sexual vitality. This extract is extracted from the Tribulus plant and standardised to ensure a consistent level of steroidal saponins per capsule.

This formula also includes the plant’s steroidal saponins as the main active component, with other minor constituents contributing to the overall profile of the extract.

What Does Tribulus terrestris extract Do?

Tribulus terrestris extract helps support sexual health and vitality, with evidence suggesting potential benefits for sexual function in some populations. Some studies indicate effects on testosterone-related processes and blood flow in context with vascular health, aligning with EFSA-friendly wording about normal physiological functions.

Research observations show mixed results for testosterone changes, while other data point to possible arterial relaxation and blood pressure support, contributing to overall vitality as described in the research context. NHS/EFSA guidance emphasises normal hormone-related processes and vascular function in healthy individuals.
