Tribulus Terrestris Fruit

Also known as: Puncturevine, Trib, *Tribulus terrestris*

Overview

*Tribulus terrestris* is a flowering plant commonly used in herbal medicine for various health issues, particularly sexual dysfunction and infertility. Rich in steroidal saponins and flavonoids, this supplement exhibits antioxidant and anti-inflammatory properties. Traditional uses include enhancing libido and improving erectile function, though studies have shown inconsistent effects on testosterone levels. The body of research around *Tribulus terrestris* includes systematic reviews and meta-analyses, highlighting its potential to benefit individuals experiencing sexual health issues. However, the maturity of research can be variable, with some evidence rated as moderate in quality.

Benefits

The primary evidence-based benefits of *Tribulus terrestris* include the enhancement of sexual desire and satisfaction, particularly for individuals experiencing sexual dysfunction. Clinical studies indicate significant improvements in sperm concentration (SDM = 0.624, 95% CI = 0.13 to 1.117, p = 0.013) and motility (SDM = 0.742, 95% CI = 0.331 to 1.152, p = 0.001). Secondary effects may include modest reductions in blood pressure and cholesterol levels. Most benefits are particularly pronounced in males facing infertility or sexual performance issues, though evidence remains mixed concerning its effects on testosterone levels.

How it works

*Tribulus terrestris* primarily works by enhancing the release of nitric oxide in the body, which leads to improved blood flow to the penis and relaxation of smooth muscle tissues. This action not only supports cardiovascular health but also plays a critical role in reproductive health. The interactions with nitric oxide pathways are essential for its proposed effects on sexual function, although specific absorption data remain sparse.

Side effects

Overall, *Tribulus terrestris* is generally considered safe with no significant adverse effects reported in clinical trials. Common side effects are not consistently reported; however, caution is advised in certain populations such as pregnant and breastfeeding women due to limited safety data. Potential drug interactions may occur with medications that affect blood flow or glucose levels, such as anticoagulants and diabetes medications. Special care should be taken for individuals with underlying health conditions, including diabetes and cardiovascular issues, although no major contraindications are noted.

Dosage

The recommended dosage for *Tribulus terrestris* typically starts at 750 mg per day, with an optimal range of 750 to 1,500 mg per day of the extract. While specific maximum dosages are not well-defined, studies have safely used up to 1,500 mg per day. There are no specific timing recommendations for administration, and the extract form is commonly utilized. Limited data on absorption factors suggest that individual responses may vary, and no cofactors have been established.
