Tongkat Ali
Traditional Southeast Asian herb (Eurycoma longifolia) studied for testosterone support, stress reduction, and athletic performance.
How it works
Mechanism of Action
Reduces cortisol and SHBG (sex hormone-binding globulin), potentially freeing more testosterone. Contains quassinoids and eurycomanone which may stimulate Leydig cell function.
Evidence-based uses
What Tongkat Ali Is Used For
Studies show improvements in testosterone, cortisol ratio, and subjective energy. Effects more pronounced in stressed or aging individuals.
Clinical Evidence
Tongkat Ali 200mg/day for 4 weeks significantly reduced cortisol (−16%) and increased testosterone (+37%) in moderately stressed subjects. Improvements in tension, anger, and confusion.
May support lean body mass and recovery via hormonal optimisation. More research needed in athletic populations.
Clinical Evidence
Tongkat Ali supplementation showed improved lean body mass and muscular strength in physically active males over 5 weeks of strength training.
Safety
Interactions & Warnings
Tongkat Ali may have additive effects with exogenous testosterone, potentially increasing hormonal side effects.
Tongkat Ali may slightly lower blood pressure. Monitor if taking antihypertensives.
