What is Tribulus Terrestris?
Tribulus Terrestris is the Latin name of an herbaceous plant belonging to the Zygophylla family, also known as "Earth-Thorn" or "Earth Star." The plant grows in subtropical regions of Asia, Africa, and Southern Europe. It first came to prominence in the 1980s when studies in Bulgaria investigated its potential for improving libido and sexual performance in men. As a result, the first Tribulus supplements came onto the market, advertised as a multi-action testosterone booster.
The effect of Tribulus Terrestris
Tribulus Terrestris has been the subject of numerous studies due to its bioactive substances such as alkaloids, flavonoids, and saponins. Saponins, which are similar to steroid hormones, have attracted particular interest as they could potentially represent a healthy alternative to anabolic steroids. Various applications have been investigated, including potential improvements in exercise performance, blood sugar regulation, potency enhancement in men, and libido enhancement in women.
What is proven and what is not?
Study results from the 1990s and 2000s were promising, but their validity was questionable. More recent studies have produced a mixed picture:
- Increase testosterone levels:The increase in luteinizing hormone (LH) by Tribulus Terrestris did not lead to significant changes in testosterone levels in human studies, especially in individuals with already healthy testosterone production.
- Muscle mass and strength:Reliable studies on its muscle-building effect are lacking. Existing studies have not produced positive results, possibly due to lower administered doses compared to the recommended amounts.
- Improvement of potency and sexual desire:Studies have shown potential improvements in libido in men and women, without clear clarification of the underlying mechanism.
- Blocking carbohydrate absorption:Studies have suggested that Tribulus Terrestris blocks enzymes in the intestine responsible for carbohydrate absorption, which may have a positive effect on blood sugar and cholesterol levels.
- Drainage:The plant can have a diuretic effect, causing increased excretion of chloride and sodium, which at high doses can be comparable to medicinal diuretics.
Taking and dosage of Tribulus Terrestris
Tribulus Terrestris is typically offered as an extract in capsule form or as a powder. The dosage should be at least 750 mg per day to achieve effects. Powder is pure but difficult to dose and bitter, while capsules are more convenient to take.
Who should buy Tribulus Terrestris?
The use of Tribulus Terrestris may be of interest to individuals experiencing increased hormone production, performance plateaus during training, sexual problems, unwanted water retention, or difficulty making progress with a diet. It may also be useful for older athletes to support hormonal balance.
Side effects
Apart from possible temporary stomach upset at extremely high doses and a potential interaction with diabetes medications, no side effects are known. There is no evidence of damage to the prostate, liver, or heart.
What to look for when buying
The saponin content is crucial for the effectiveness of Tribulus preparations. The amount of saponin varies depending on the geographical origin of the plant. A standardized percentage on the label provides information about the saponin content.
