The Short Answer
Tongkat Ali (Eurycoma longifolia) contains quassinoids, particularly eurycomanone, which enhance testosterone production by stimulating luteinizing hormone release from the pituitary gland. This Malaysian herb also reduces cortisol levels through modulation of the hypothalamic-pituitary-adrenal axis, improving stress response and energy metabolism.

Commonly consumed in extract or capsule form, with a dosage of 200-400 mg per day. Consult a healthcare provider before use.
Nutritional Profile
- Contains quassinoids, compounds with health benefits. - Rich in eurycomanone, supporting testosterone levels. - Provides antioxidants.
How It Works
Mechanism of Action
Tongkat Ali's primary bioactive compounds, eurycomanone and other quassinoids, stimulate the hypothalamic-pituitary-gonadal axis by increasing luteinizing hormone (LH) release, which signals testosterone production in Leydig cells. The herb also inhibits phosphodiesterase enzymes and modulates the HPA axis by reducing cortisol synthesis. Additionally, quassinoids enhance cellular ATP production through improved mitochondrial function and glucose metabolism pathways.
Clinical Evidence
Multiple randomized controlled trials involving 200-400 participants demonstrate significant testosterone increases of 15-37% with 200-400mg daily doses over 4-12 weeks. Studies show cortisol reductions of 16-26% and improved sexual function scores in both healthy and subfertile men. However, most studies are relatively small-scale (25-109 participants) and conducted primarily in Southeast Asian populations, limiting broader generalizability. Evidence quality is moderate, with some studies lacking proper placebo controls.
Safety & Interactions
Tongkat Ali is generally well-tolerated with mild side effects including restlessness, insomnia, and increased body temperature reported in some users. It may interact with diabetes medications by affecting blood glucose levels and could potentially interfere with hormone-sensitive conditions or medications. The herb should be avoided during pregnancy and breastfeeding due to insufficient safety data. Individuals with prostate cancer or other hormone-sensitive conditions should consult healthcare providers before use.

Frequently Asked Questions
How much tongkat ali should I take daily
Clinical studies typically use 200-400mg daily of standardized extract containing 0.8-1.5% eurycomanone. Most studies show benefits with 200mg taken once daily, while some use split doses of 200mg twice daily for enhanced effects.
How long does tongkat ali take to work
Testosterone increases typically appear within 2-4 weeks of consistent use, with peak benefits observed after 8-12 weeks. Energy and mood improvements may be noticed within 1-2 weeks, while sexual function improvements generally require 4-6 weeks of supplementation.
Does tongkat ali increase testosterone in women
Limited research suggests tongkat ali may provide modest testosterone increases in women, potentially improving energy and libido. However, most studies focus on men, and women should use lower doses (100-200mg) due to different hormonal sensitivities and potential masculinizing effects.
Can tongkat ali cause side effects
Common mild side effects include restlessness, insomnia, increased body temperature, and occasional digestive upset. These effects are typically dose-dependent and resolve with dosage reduction. Rare cases of mood changes or increased aggression have been reported with high doses.
Is tongkat ali safe to take with other supplements
Tongkat ali generally combines safely with most supplements, but caution is advised with other testosterone boosters, stimulants, or adaptogens to avoid overstimulation. It may enhance the effects of blood sugar-lowering supplements and should be monitored with diabetes medications due to potential glucose-lowering effects.
