Tribulus Terrestris Extract is a concentrated botanical extract derived from the aerial parts and fruit of Tribulus terrestris, a plant used in both Ayurvedic and Traditional Chinese Medicine for centuries as a male tonic, aphrodisiac, and kidney health herb. Standardised to contain more than 20% saponins (UV), this extract delivers a consistent dose of furostanol saponins — particularly protodioscin — which are the primary bioactive compounds associated with Tribulus’s testosterone-supporting, libido-enhancing, and athletic performance effects.
Tribulus Terrestris Extract is one of the most widely used men’s health supplement ingredients globally, with particular strength in sports nutrition and male sexual health formulations.
Applications:
- Men’s Health (testosterone support, libido enhancement, male vitality supplements)
- Sports Nutrition (muscle strength, power output, and recovery formulations)
- Nutraceuticals (kidney health, urinary support, and general men’s wellness)
- Traditional Herbal Medicine (Ayurvedic and TCM male tonic formulations)
Key Features & Benefits:
- >20% saponins (UV) – standardised protodioscin-rich testosterone support extract
- One of the most widely used men’s health botanical ingredients globally
- Supports testosterone levels, libido, and athletic performance
- Halal-certified & food-grade quality
- Suitable for capsule, tablet, and powder formulations
“20% saponins (UV)” is a total, not protodioscin
Tribulus extract is standardised to total saponins measured by UV (spectrophotometry). UV measures a broad group of saponins together, so its figure is higher than any single saponin measured by HPLC. Protodioscin, the furostanol saponin most often discussed, is measured by HPLC. If you want to compare extracts, ask for protodioscin by HPLC as well as the UV total.
Plant part and origin change the profile
Tribulus terrestris extract is made from the fruit and aerial parts. The saponin profile differs with the part used and the region where the plant grows, so two extracts with the same UV figure can contain different saponins. Ask for the plant part and origin on the specification.
Formulation notes
The extract is bitter and is mostly used in capsules and tablets. It is often formulated with Tongkat Ali Extract or Horny Goat Weed Extract. Claims about testosterone need care: see the research below.
What the research says
- A 2025 systematic review of 10 studies (483 men) found that tribulus at 400–750 mg a day for 1 to 3 months improved erectile function in 3 of 5 studies that measured it. Eight of 10 studies found no change in androgen levels, and the authors found no robust evidence that tribulus raises testosterone. Half the studies were of low methodological quality. [1]
- A 2025 meta-analysis of 8 studies in men with erectile dysfunction found higher erectile function scores with tribulus than with placebo, no difference in total testosterone, and no difference in adverse events. [2]
- A 2023 systematic review of 52 studies of “testosterone boosters” found that most fail to increase total testosterone; tribulus was not among those the authors considered effective. [3]
