What the AI looks for in Tribulus Herbal Supplements
- Saponin standardization
- Choose an extract that states a saponin percentage, commonly in the 40 to 60% range. Unstandardized powders vary widely in active content.
- Plant part and origin
- Prefer fruit or aerial-part extracts that name the origin. Protodioscin content varies by region. The chemistry of tribulus differs a lot between sources, and that variation shows up in studies.
- Realistic goal
- Judge it on libido, not on testosterone. Evidence for higher testosterone in healthy men is weak, while some data support effects on libido.
- Single ingredient
- Prefer tribulus-only products over 'test booster' blends. Proprietary blends hide doses and often add stimulants.
Brands that matter
- NOW Foods: Standardized extract tablets with broad availability.
- Nutricost: Budget single-ingredient capsules.
- Optimum Nutrition: Long-running sports-nutrition tribulus capsule.
What to avoid
- Testosterone-booster blends with undisclosed proprietary amounts.
- Products that claim steroid-like muscle gains.
- Taking it alongside blood pressure or diabetes medication without asking a doctor.
Questions
