Study, Trial or Testing Result Summary
Members Only7 human studies · 7 improved
This product gives 1500 milligrams of Tribulus fruit extract a day, which is at or above the amounts used in the studies below. A 2021 review that pooled trials of natural products for women's sexual problems found Tribulus beat placebo for overall sexual function, arousal, desire and orgasm [1]. In a trial of 67 women with low desire, a small daily dose of extract for 4 weeks improved desire, arousal, lubrication, satisfaction and pain more than placebo, with side effects similar to placebo [2]. In 45 postmenopausal women with low libido, 750 milligrams a day for about four months improved desire, arousal, pain and orgasm while placebo did not, and free testosterone rose [3]. A trial of 40 premenopausal women with low libido found similar gains over placebo, again with a rise in free testosterone [4]. In 60 postmenopausal women, an extract syrup taken for 8 weeks raised sexual satisfaction compared with before treatment [5]. A hospital record study with no comparison group found that most women taking 250 milligrams three times daily for 90 days improved [6]. The trials were small and short, so the evidence is consistent but not large. Animal and cell studies are never counted.

Review Totals and Summary
Members Only7,522 reviews · 93% positive
This Nutricost Tribulus Terrestris Extract product, specifically the 1500mg capsules, has garnered approximately 5763 ratings across various stores, with 70% of them being 4 or 5 stars. The overall sentiment is largely positive, with many users reporting beneficial effects. **What it did for buyers:** Many customers report positive outcomes, frequently noting increased energy and improved performance. Users describe a "minor to mild boost" in addition to other supplements, and it "works great for strength training." Some experience a "definite boost in energy after only 3 days" and find it "supports stamina, recovery, and testosterone levels." It is often praised for enhancing fitness, vitality, and overall wellness, with some noticing tangible benefits within a week. **What buyers complain about:** While generally positive, some users report not experiencing the desired effects. One customer stated, "Haven't noticed much of a difference," particularly regarding sex drive. Another felt the product was "very wimpy!" and suspected it was "grossly under dosed," noting they "didn't really notice anything." A few users also reported no noticeable benefit or an increase in urination. There was also an isolated complaint about receiving an incorrect product count and dosage compared to the order. **Taste, smell, and pill attributes:** The capsules are generally considered easy to swallow. Many customers find the "Capsules are easy to swallow, not too big," and note smooth digestion with no weird aftertaste during normal consumption. However, one user warned that if a capsule breaks open in the throat, "it has a horrible taste," prompting them to take it with juice. (Note: Reviews discussing the taste of a powder form were excluded as this summary focuses on capsules.) **Value for money:** Customers frequently highlight the product's excellent value. It is described as "cost efficient and effective quality" and a "great item for a great price." The generous supply of 240 capsules per bottle, providing 120 servings, is often appreciated for its overall value and large size. **Who it seems to suit and who it did not:** This supplement appears to be well-suited for individuals engaged in "strength training" and "work out purposes," as well as athletes and those seeking to enhance their fitness or daily wellness regimen, particularly for men's support. It may not be suitable for everyone, as some users, like one seeking to increase sex drive, reported, "Haven't noticed much of a difference." Similarly, those who found it "wimpy" or experienced no noticeable benefits did not find it suitable for their needs.
Biohacker Summary
Members Only4 of 10 recommend it
The panel is split on tribulus terrestris, the main ingredient here, and leans toward caution. Three of the seven who spoke about it warn against it in their latest statements, saying evidence for raising testosterone is weak or disproven, and one of them calls it junk and another says it does not build muscle. Two recommend it, mainly for libido or for raising testosterone in women, and two are neutral, with one of those having stopped using it and swapped it for another herb after seeing little effect on testosterone. The only dose given was 600 milligrams daily for libido, and others said results may depend on a high saponin content and good quality, or be short lived. Some past advice was to pair it with other compounds and a balanced diet.

More Details
Members OnlyBody systems · Combine with · Possible side effects
Body systems: Reproductive system, Endocrine system
Combine with: To enhance the effects of Tribulus Terrestris for female libido, consider combining it with Maca Root, which is known for its adaptogenic properties and ability to support energy, mood, and sexual desire. L-Arginine or L-Citrulline can also be beneficial as they are precursors to nitric oxide, potentially improving blood flow to sexual organs and enhancing arousal. Additionally, Ashwagandha, an adaptogenic herb, can help manage stress, which often negatively impacts libido, thereby indirectly supporting sexual health. Fenugreek extract is another option that has shown promise in supporting female sexual function and desire.
Possible side effects: In the trial that reported them, side effects were similar to placebo. A few buyers mentioned more frequent urination and a bad taste if a capsule breaks open in the throat.
