Eurycoma Longfolia Jack
Also known as: Tongkat Ali, Malaysian ginseng, Longjack, Eurycoma, Pasak Bumi, Eurycoma longifolia
Overview
Eurycoma longifolia, commonly known as Tongkat Ali, is a herbal supplement originating from Southeast Asia, particularly in Malaysia and Indonesia. Traditionally, it has been utilized to enhance male fertility, boost libido, and promote overall wellbeing. The plant contains several active compounds, notably quassinoids, with eurycomanone being the most significant. Recent studies have increasingly focused on its potential for elevating testosterone levels, improving erectile function, and exhibiting antimicrobial and antiparasitic effects. Evidence regarding its efficacy is growing, especially for treating male hypogonadism, though additional long-term studies are necessary to fully confirm its safety and effectiveness for broader applications.
Benefits
Eurycoma longifolia has been shown to significantly increase testosterone levels, with evidence from a systematic review indicating a standardized mean difference (SMD) of 1.352 (95% CI 0.565 to 2.138, p = 0.001) in men with hypogonadism. Furthermore, there are indications that the supplement may improve erectile function, though the supporting data is less conclusive. Some studies have also reported antimicrobial and antiparasitic properties, as well as modest enhancements in muscle strength when combined with resistance training. Despite the clinically significant testosterone elevation, further research is warranted regarding its effectiveness for erectile dysfunction and muscle performance.
How it works
Eurycoma longifolia primarily influences the hypothalamic-pituitary-gonadal (HPG) axis, promoting increased testosterone production. It is believed to inhibit key enzymes such as phosphodiesterase and aromatase, which are necessary for steroid hormone synthesis. The active compounds, mainly quassinoids, interact with specific cellular mechanics that regulate hormonal levels. While studies on absorption are limited, it is suggested that these active components may be bioavailable when ingested as a supplement.
Side effects
Eurycoma longifolia is generally considered safe when taken within recommended dosages, and serious adverse effects are rare. While common side effects reported are insignificant (occurring in less than 5% of users), uncommon and rare side effects are not well quantified. Caution is advised since drug interactions are limitedly studied, particularly regarding medications affecting hormone levels. Pregnant or breastfeeding women and individuals with hormone-related health conditions should avoid use or consult a healthcare provider before use. Overall, data on long-term safety is sparse, necessitating careful consideration.
Dosage
The suggested dosage for Eurycoma longifolia typically ranges from 200 to 400 mg daily, preferably from standardized root extracts. Individual response may dictate variation in dosage within this range. There is no specific timing for administration, but maintaining a consistent schedule is recommended for optimal results. Current literature suggests that taking it with food may enhance absorption, although definitive evidence is limited. No established maximum dosage exists, but caution is advised when considering doses exceeding 400 mg daily due to insufficient research on larger quantities.
