Tongkat Ali Lj100
Also known as: Tongkat Ali, Pasak Bumi, Longjack, Eurycoma longifolia
Overview
Eurycoma longifolia, commonly known as Tongkat Ali, is a medicinal plant native to Southeast Asia. Traditionally used in herbal medicine, its roots are primarily utilized for enhancing male fertility and sexual health. Increasingly popular as a dietary supplement, Tongkat Ali is primarily aimed at improving erectile function, raising testosterone levels, and supporting overall male vitality. Several meta-analyses have emerged in recent years, reflecting an increase in research activity surrounding its health benefits; however, while some evidence is promising, the methodological quality of the studies presents a challenge for definitive conclusions. Various supplement forms of Tongkat Ali exist, often processed into standardized extracts that are purportedly bioactive.
Benefits
Research has shown several benefits tied to Tongkat Ali supplementation, particularly its role in increasing testosterone levels. A systematic review and meta-analysis revealed a significant increase in total testosterone (SMD of 1.352, 95% CI 0.565 to 2.138, p = 0.001). Additionally, it showed positive outcomes in erectile function based on the International Index of Erectile Function (IIEF-5), despite noted methodological biases. Hypogonadal men appear to benefit most from supplementation, and observed effects usually manifest within 6-12 weeks. While evidence for secondary increases in free testosterone and cortisol exists, the clinical significance merits further exploration.
How it works
Though the precise mechanisms of Tongkat Ali are not completely elucidated, it is believed to enhance hormonal activity by regulating the hypothalamic-pituitary-gonadal axis, leading to increased testosterone synthesis. Active components in the plant may modulate steroidogenesis, although specific molecular targets remain inadequately identified. Variability in bioavailability among products can impact the efficacy of active compounds, necessitating further investigation.
Side effects
Tongkat Ali is generally well tolerated for short durations, but a few side effects have been reported. Common mild effects (occurring in >5% of users) are unknown due to limited data, while insomnia, restlessness, and rapid heartbeat fall into the uncommon category (1-5%). The long-term safety profile is not well established, with scarce evidence for rare adverse effects (<1%). Care should be exercised regarding potential interactions with medications such as propranolol, especially those impacting cardiovascular health. Contraindications exist for individuals with specific conditions (e.g., breast or prostate cancer, diabetes, and heart disease) as well as for vulnerable populations like children and pregnant women.
Dosage
While the minimum effective dosage is not definitively established, common dosing ranges from 200-600 mg per day, with an average around 300-400 mg. Typically, users take the supplement once or twice daily. Notably, studies exploring effects on testosterone and erectile function generally observe benefits in the 6-12 week timeframe. Root extracts are the standard form used, often standardized to specific bioactive constituent levels, with absorption impacted by product formulation. No overarching maximum safe dose is defined, but intake exceeding 600 mg daily is less common in research contexts.
FAQs
Is Tongkat Ali safe for long-term use?
Tongkat Ali is generally considered safe for short-term use; however, long-term safety data is lacking and should be approached cautiously.
How quickly can I expect to see results?
Improvements in testosterone and erectile function are typically observed within 6-12 weeks of consistent supplementation.
Can Tongkat Ali replace prescribed medications?
Tongkat Ali should not be considered a substitute for prescribed medications for underlying health issues and should be used under healthcare professional guidance.
