Tribulus terrestris is a plant extract often marketed as a natural testosterone booster, though evidence for this effect is mixed. It contains saponins like protodioscin, which may support libido and athletic performance by indirectly influencing hormone pathways. Some studies suggest it enhances strength and aggression in athletes, but results are inconsistent.
While it’s popular in bodybuilding circles, its primary benefits may relate to vitality and sexual health rather than direct muscle growth. It’s commonly found in “testosterone support” blends alongside fenugreek or ashwagandha.
Synonyms: Puncture vine, Gokshura (Ayurvedic name)
Benefits:
- May support libido and sexual function.
- Potential mild boost to athletic performance.
- Used in traditional medicine for vitality.
Sources: Tribulus capsules, testosterone boosters.
Notes: Excessive use may cause stomach irritation. Not proven to significantly increase testosterone alone.
