Few studies reported a significant increase in testosterone levels with low clinical magnitude (~60–70 ng/dL) in men with hypogonadism 9,21. Furthermore, TT supplementation did not increase testosterone levels, while these studies did not focus on men with hypogonadism 8,11,12,13,18,23,24,25. The study eligibility criteria involved clinical trials and case reports that encompassed men submitted to TT supplementation alone and that assessed serum androgen levels or sexual function. Some studies indicate that TT supplementation modulates androgen profile through an increase in serum testosterone levels and the testosterone/estradiol ratio 8,9. Therefore, only 2 studies showed significant intra-group increase in total testosterone levels, which had low clinical magnitude (60–70 ng/dL) and involved subjects with hypogonadism. – Known to decrease cortisol levels in the body which work in association with testosterone-boosting supplements.
This condition doesn't just cause energy loss, fatigue, and reduced physical ability - it also leads to erectile dysfunction, which can really affect a man's health . The benefits vary a lot if you're an older man thinking about taking tribulus supplements. Today, companies market it as a natural way to boost testosterone and improve sexual health and energy levels. While it seems that Tribulus terrestris may improve libido in women and men, more research is needed to clarify the extent of the sexual effects of this supplement. Some research shows that taking 800 mg of this supplement per day may not effectively treat erectile dysfunction (11). However, studies in men with erectile dysfunction have yielded mixed results.. In both studies, subjects received 3 capsules daily (750 mg) of TT (Trib Gold, origin Bulgaria, 250 mg of TT and a minimum of 45% of saponins per capsule) over the course of 3 months. Concerning the main outcomes, all studies investigated the effects of TT supplementation on serum androgen levels. Zygophyllaceae (TT) has been used for centuries, mainly in India and China, as an herbal medicine and as a sexual stimulant to treat ED and augment testosterone levels. It is good to know that there are many testosterone-boosting supplements out on the market which is made up of high-quality all-natural ingredients.}
Elderly men thinking about tribulus dosage might see benefits beyond just testosterone increases. That's why some studies show better IIEF scores (International Index of Erectile Function) even without measuring higher testosterone levels . This suggests tribulus terrestris might help men with hormone deficiencies more than those with normal hormone levels. The treatment increased testosterone levels to about 150% of control groups .
Studies in rats showed that regular TT intake improved erections due to increased genital blood pressure. TT affects erectile function through nitric oxide (NO) mechanisms beyond hormonal pathways . Animal studies showed that taking TT improved LH levels by a lot . Protodioscin, the most studied compound in TT, helps increase how much testosterone converts to dihydrotestosterone (DHT) . This creates a feedback loop that gets the body to produce more testosterone . Your starting hormone levels play a big role in how well they might work. Tribulus terrestris can help men who have very low libido - one study found their sexual desire jumped 79% after taking 750–1,500 mg daily for two months.
Tribulus terrestris ended up offering modest but helpful benefits for specific men over 60, especially those with mild sexual dysfunction or low testosterone levels. Clinical studies have showed TT can boost sexual function even when testosterone levels stay the same. Importantly, studies that reported null effects of TT supplementation on testosterone levels did not focus on patients with low testosterone. These studies 9,21 reported an increase in testosterone levels (60–70 ng/dL) with a low clinical magnitude effect; therefore, this result can likely be replicated in real-world scenarios and future studies. In summary, the aforementioned studies 9,21 support a potential ~60–70 ng/dL increase in total testosterone levels following TT supplementation in men with low testosterone levels at baseline within a context of poor methodological quality.
In one study, researchers tested the herb in 24 elite rugby players. Here's a quick video I made to summarize some of the studies below More LH means more testosterone is made. The word Tribulus is Latin for "to tear", another reference to the plant's ability to do damage. The term puncture vine stems from rumors that the plant’s thorns are able to puncture bicycle tires. Tribulus (also called puncture vine), is a plant that is found throughout the world.
Most clinical studies use daily tribulus testosterone doses between 750–1,500 mg. A study of older men with partial androgen deficiency showed a clear link between testosterone levels (both total and free) and IIEF-5 scores after taking TT . TT supplements can substantially boost libido without changing hormone levels. This works especially well for those with reduced blood flow or mild erectile dysfunction linked to andropause.
This is where the traditional use of the plant aligns with modern science. Differences in physiology and metabolism mean that effects seen in animal models do not always translate to people. Much of the initial excitement came from studies on animals, such as rats and primates. The theory behind the testosterone claim involves the Luteinizing Hormone (LH). The central question for most users is its direct impact on testosterone. It was historically used for a variety of purposes, including issues related to urinary tract health and vitality. Tribulus terrestris is a small, leafy plant that has been a part of traditional medicine systems, like Ayurveda and Traditional Chinese Medicine, for centuries.
