Tribulus Terrestris & Weight Loss
Effects on Body Composition in Athletes
A study focused on the impact of Tribulus Terrestris supplementation on body composition and performance in CrossFit athletes. Over six weeks, participants took either a placebo or 770 mg of Tribulus daily.
The results indicated that while testosterone levels increased, there were no significant changes in body composition or performance metrics between the Tribulus and placebo groups. This suggests that Tribulus may not effectively aid in weight loss or muscle gain for athletes.
Tribulus Terrestris & Blood Sugar Management
Efficacy of Tribulus Terrestris in Diabetes Management
A study investigated the effects of Tribulus Terrestris extracts on diabetic rats. The researchers divided the rats into groups and treated them with different doses of Tribulus. They found that both types of extracts (low and high protodioscin content) significantly reduced elevated blood sugar levels after 12 weeks.
The extract with higher protodioscin showed faster results by lowering blood sugar from the first week. The study suggested that the blood sugar-lowering effect might be due to increased activity of certain enzymes that help manage glucose levels.
Comparison with Metformin
In a study comparing Tribulus Terrestris to the diabetes medication metformin, researchers found that both treatments helped lower blood sugar levels in diabetic rats. The Tribulus extract helped reduce blood sugar and also alleviated oxidative stress, which is harmful to the body.
Tribulus Terrestris & Hormone Balance
Hormonal Behavior and Health Biomarkers
A systematic review looked at various studies on Tribulus Terrestris and its effects on hormonal behavior in physically active adults. The review concluded that there is no conclusive evidence supporting the idea that Tribulus significantly influences hormone levels, including testosterone, in healthy individuals.
Hormonal Effects in Animal Studies
Research involving male rats found that Tribulus Terrestris could influence sex hormone levels and gonadotropins (hormones that stimulate other glands). The study suggested that Tribulus might have a role in boosting sexual function and hormone balance in these animals. However, it is important to note that results from animal studies do not always translate into replications in human trials.
Tribulus Terrestris & Menopause Management
Impact on Sexual Function in Menopausal Women
A clinical trial studied the effects of Tribulus Terrestris on sexual function in 60 postmenopausal women experiencing sexual dysfunction. After 90 days of treatment, the results showed significant improvements in sexual desire, interest, foreplay, arousal, and comfort during intercourse for those taking Tribulus compared to the placebo group.
Efficacy for Hypoactive Sexual Desire Disorder
Another randomized, double-blind study focused on women with hypoactive sexual desire disorder. The participants took Tribulus Terrestris for four weeks, and the findings indicated significant improvements in sexual desire, arousal, lubrication, and satisfaction, alongside reduced pain during intercourse. This study supports the idea that Tribulus can help improve sexual health in women experiencing decreased libido during menopause.

Tribulus Terrestris Interactions with Drugs or Supplements
Potential Drug Interactions
- Blood Pressure Medications: Tribulus may lower blood pressure, so it could interact with antihypertensive drugs and cause blood pressure to drop too low. This includes medications such as beta-blockers, calcium channel blockers, and ACE inhibitors.
- Diuretics: There is a possibility of interaction with diuretics, which could increase the effects of these medications and lead to dehydration or electrolyte imbalances.
- Diabetes Medications: Tribulus could interact with antidiabetic medications and increase the risk of hypoglycemia (dangerously low blood sugar) for those taking insulin or other diabetes medications.
- Blood Thinners: There have been reports of blood clots in patients taking Tribulus alongside blood thinners like clopidogrel. While it’s unclear if Tribulus directly causes these effects, caution is advised.
- Hormonal Medications: Tribulus may affect hormone levels, which could interact with medications like steroids or hormone replacement therapy.
Combining with Other Supplements
Tribulus Terrestris can be safely combined with some supplements, but caution is advised. For example, combining it with other hormone-balancing herbs like ashwagandha or ginseng can increase its effects. However, taking it together with other supplements that affect hormone levels or blood sugar should be done under the guidance of a healthcare provider.
