The Active Ingredient Is: Tribulus Terrestris Extract

Tribulus terrestris extract is a plant-based supplement ingredient used to support normal physiological functions associated with vitality. This extract is standardised to a high saponin content to help deliver its bioactive components within a vegan capsule form.

This formula also includes zinc citrate as a supporting nutrient, which is essential for maintaining normal testosterone in the blood, aligning with the product’s overall focus on male vitality and exercise performance.

What Does Tribulus Terrestris Extract Do?

Tribulus terrestris extract may support natural testosterone production by stimulating luteinising hormone release, contributing to testosterone output in the body. Zinc in the formula supports normal testosterone maintenance, while the overall combination emphasises muscular and vitality-related functions in line with EFSA-style guidance.

Evidence from scientific research suggests these mechanisms may occur, reinforcing the role of this blend in supporting normal physiological processes without medical claims.
