Amino Z Tribulus Terrestris Powder
Tribulus terrestris is not a new kid on the block; rather, it has been around a number of years, and much longer than that in parts of Asia and Europe.
Also known as Devil’s weed or puncture vine, it is also very common in parts of the Western United States, being a mainstay in supplements that support men’s health.
If you’ve never heard of tribulus before, or are looking for a good starting point for hormonal optimization, you’re in the right place.
Let’s explore what makes tribulus so popular.
May Enhance Libido
If you’ve ever read the label of any male enhancement supplement that is supposed to improve your libido, then you’ve also likely seen tribulus as one of the first ingredients. The reason is simple- it works.
Studies have found that tribulus may not only improve libido in men, but also in women[i]! Its aphrodisiac properties have been used in ancient Ayurvedic and Oriental medicine for centuries. Dosages of between 500-1500mg daily were usually necessary to be consumed over the course of several weeks for these effects to manifest.
May Have Pro-Erectile Properties
Erectile dysfunction medications are a billion dollar industry. Men looking for a milder and more natural option may be pleased by the effects tribulus can deliver for them. One of the most popular studies on the subject investigated 30 men [ii]that had self-reported erectile dysfunction, with an average age of 60 years, placed into either placebo or subject groups.
Tribulus administered at the dose of 600mg daily in two split doses yielded significant improvement to their erectile function index, while placebo group reported no improvement. It is noteworthy, however, that testosterone values of these subjects did not increase at all, indicating that a non-testosterone related mechanism was at play.
May Improve Semen Quality
Tribulus may also have a place in the treatment of low sperm count (oligospermia), or to improve aspects of sperm health such as motility and viability. Although this effect is not drastic, there have been studies done which display improvements to men that were otherwise considered infertile[iii].
Tribulus Has Anti-Oxidant Properties
Tribulus supplementation may have a protective effect on organs such as the liver, kidneys and testes[iv], helping to reduce the oxidative damage and stress these organs may be subjected to. This effect may be more pronounced if you are living in an urbanized city with exposure to many toxins and possibly harmful by-products of manufacturing facilities.
It also has a strong protective effect on the kidneys, going as far as to possibly diminish your risk of developing kidney stones[v].
To finally address the elephant in the room- does tribulus increase testosterone levels? Unfortunately, the answer is leaning in the direction of no. It may modestly increase levels of luteining hormone, which in turn may increase testosterone a little, but this effect is primarily observed in men that have very low testosterone levels to begin with.
Try to shoot for a daily dose of 750-1500mg taken in two split doses for best results.
