Tribulus Terrestris: An Honest Look at the Evidence for Men

Tribulus is in almost every men's vitality formula. Here is what controlled trials found for testosterone, libido and performance, the saponin standardisation question and who should avoid it.

Traditional Use, Modern Hype

Tribulus terrestris is a creeping plant used in Ayurvedic and Traditional Chinese Medicine for vitality and urinary health. Its modern reputation as a testosterone booster came from bodybuilding marketing in the 1990s and has largely outrun the data.

What Trials Show

Multiple randomised trials in healthy men and athletes have found no effect of tribulus on testosterone, muscle mass or strength. A few trials in men with low libido report improved desire scores, and one small study in men with mild erectile difficulty reported improvement at a high standardised dose. The honest summary is no hormonal effect, a possible modest effect on desire, and nothing for performance in healthy men.

Standardisation Matters

Tribulus products vary widely in their content of protodioscin and other saponins depending on plant part and origin. Trials that reported libido effects used extracts standardised to high saponin levels. An unstandardised amount inside a multi-herb blend cannot be compared with those studies.

Safety

Tribulus is generally well tolerated short-term. It is usually avoided by men with prostate conditions because of theoretical hormonal effects, by anyone on diabetes or blood-pressure medication because of additive effects, and in pregnancy. A product page that lists these cautions is treating the herb seriously; one that calls it a natural steroid is not.
