5 Surprising Benefits Of Tribulus

Tribulus is a compound many people who work out have probably heard of, as it is a common ingredient in muscle-building supplements. However, stimulating muscle growth isn’t its main use. Do you know what it is most commonly used for? If your answer is no, don’t worry—you’re in the majority. That’s why we decided to publish an article on the 5 surprising benefits of Tribulus, to clear up misconceptions about its purpose.

In this article, we will explain exactly what Tribulus is, outline the benefits it offers, and show how it produces each of them. This will give you all the information you need to understand why Tribulus is so popular—and hopefully convince you to try it for yourself and experience its health benefits firsthand.

What Is Tribulus & How Does It Work?

Tribulus is a herbal extract made from the fruit of Tribulus terrestris, a small flowering plant in the caltrop family. It grows in warm, dry regions of Europe, Asia, Africa, and Australia.

For centuries, it has been used in traditional medicines across these regions, primarily for its reported health benefits linked to sexual health and function, especially in men.

Studies show that Tribulus must be consumed in doses of at least 225 mg to produce its benefits. Each serving of Prime Male Enhance contains 280 mg of Tribulus, making it an ideal amount. Combined with ingredients like Asian ginseng and L-arginine, the three work synergistically to boost each other’s effectiveness.

5 Surprising Benefits Of Tribulus

Regulates Hormone Levels

Tribulus is best known for its impact on sex hormones and is often promoted as a natural testosterone booster. It stimulates the pituitary gland in the brain, which increases luteinizing hormone (LH) production. LH then signals the testes to produce testosterone in men and stimulates the ovaries in women.

Tribulus also helps regulate androgen activity, which is crucial for controlling estrogen levels. This prevents estrogen from rising too high, which could otherwise lower testosterone and disrupt overall hormonal balance.

Its benefits extend beyond sex hormones. Tribulus also has adaptogenic properties that reduce cortisol, the stress hormone. Lower cortisol not only supports testosterone production but also improves energy, mood, and mental function.

Evidence suggests that Tribulus can benefit testosterone levels in all men and women, but it appears particularly effective for men with low testosterone or testosterone deficiency.

Improves Sexual Functions

Tribulus is one of the oldest known natural aphrodisiacs, with both clinical and anecdotal evidence showing it can boost libido in men and women. It works mainly by increasing dopamine, a neurotransmitter that controls pleasure and motivation, and by boosting nitric oxide (NO) levels, which enhances sexual sensitivity and desire.

In men, this often translates to greater interest in sex and stronger erections. In women, studies show it can increase arousal, lubrication, and sexual satisfaction. Tribulus may also support androgen precursors like DHEA, which further enhances these benefits and helps balance estrogen levels in both sexes.

Its effect on nitric oxide comes from stimulating nitric oxide synthase, the enzyme responsible for NO production. Nitric oxide relaxes blood vessels, improving circulation. This enhances blood flow to the penis, supporting stronger, longer-lasting erections and relieving symptoms of mild erectile dysfunction.

Tribulus also helps maintain hormonal balance, which supports libido, arousal, and reproductive health. Its adaptogenic effects reduce stress hormones, while the boost in energy improves sexual performance, stamina, and overall vitality (2).

Increases Fertility

Tribulus is also well-known for supporting fertility in both men and women. It works by influencing testosterone, estrogen, LH (luteinizing hormone), and FSH (follicle-stimulating hormone), all of which are vital for sperm production, ovulation, egg maturation, and menstrual cycle regularity.

Its antioxidant, anti-inflammatory, and adaptogenic compounds, including saponins and flavonoids, protect reproductive tissues and sperm from oxidative stress. This preserves sperm DNA, improves blood flow to the reproductive organs, and reduces stress, all of which can otherwise impair fertility.

In men, this leads to improved semen quality, including better sperm count, motility, and morphology, boosting the chances of conception. In women, it helps shield eggs from oxidative damage, particularly as reproductive age advances.

The benefits to sexual function and drive also support fertility. By enhancing libido, erections, sexual performance, confidence, and lowering stress, Tribulus makes sexual activity more likely, which in turn increases the chances of conception (3).

Boosts Energy Levels & Physical Performance

Tribulus can boost energy levels through its adaptogenic and hormonal support. By reducing physical and mental stress and balancing hormones, it increases vitality, motivation, drive, and even supports muscle growth, strength, recovery, and the desire to be active.

Its saponins, especially protodioscin, directly enhance cellular energy production, reducing fatigue and improving endurance. The antioxidant and anti-inflammatory properties protect muscles from exercise-induced damage, speed recovery, and reduce soreness after intense training.

Tribulus also boosts nitric oxide (NO) activity and blood flow, delivering more oxygen and nutrients to muscles. This improves endurance and performance, allowing longer, harder workouts more frequently.

These energy and performance benefits aren’t limited to exercise—they can also enhance stamina and performance in the bedroom (4).

Supports The Cardiovascular System

One of Tribulus’ most important yet least known benefits is supporting the cardiovascular system. Its saponins, flavonoids, alkaloids, and other active compounds reduce oxidative stress and inflammation in blood vessels and heart tissue. This helps protect against arterial stiffness, plaque buildup, and vascular damage.

Tribulus also boosts nitric oxide (NO) production, which relaxes and widens blood vessels through vasodilation. This improves blood flow, reduces strain on the heart, and supports healthy circulation. The same effects can lower high blood pressure by decreasing vascular resistance and can reduce systolic and diastolic blood pressure in people with hypertension.

Some studies suggest Tribulus may strengthen cardiac contractions and protect heart tissue from ischemia (low oxygen supply) and its damage. Its adaptogenic properties also reduce mental stress, further easing cardiovascular strain.

There is even evidence that Tribulus can help lower blood sugar, reduce LDL (“bad”) cholesterol and triglycerides, and maintain or raise HDL (“good”) cholesterol. These effects can lower the risk of chronic conditions like atherosclerosis and heart disease (5).
