Tongkat Ali Extract for Men’s Health
Share
Fatigue. Reduced strength. Low motivation. Declining sex drive. These are issues we deal with as we age or are under prolonged stress. But we don’t have to just take it. Changes in testosterone levels and elevated cortisol, a stress hormone that can interfere with muscle maintenance, recovery, mood, and overall vitality, can impact our energy, strength, and drive, but natural supplements can help.¹,²
Tongkat ali (Eurycoma longifolia), a botanical traditionally used in Southeast Asia, has been shown to support men in a number of ways. Human and animal research suggests tongkat ali may help support testosterone balance, stress response, sexual well-being, and physical performance when used responsibly and in clinically studied forms.³,⁴
Key Takeaways
-
Tongkat ali extract may help support healthy testosterone levels and stress balance, particularly in men with low baseline testosterone or chronic stress.³,⁴
-
Clinical studies suggest potential benefits for libido, mood, sperm quality, energy, and physical performance, though responses vary.⁵,⁶,⁷
-
Most human research uses standardized extracts at doses around 200 mg per day.³,⁸
-
Side effects are generally mild at standard doses, but product quality and sourcing are critical.⁹,¹⁰
-
Tongkat ali may interact with certain medications, and long-term safety data remain limited.¹¹
What Is Tongkat Ali?
Tongkat ali, also known as Eurycoma longifolia or Malaysian ginseng, is a flowering plant native to Southeast Asia. Extracts from its root have traditionally been used to support vitality, physical performance, and male reproductive health.¹,³
Modern supplements typically rely on standardized extracts that concentrate naturally occurring bioactive compounds such as quassinoids, eurypeptides, and glycosaponins. These compounds are believed to influence hormone regulation, stress response, and energy metabolism.¹²,¹⁴
Potential Benefits of Tongkat Ali for Men
Supporting Healthy Testosterone Levels
Several clinical studies suggest tongkat ali may help support testosterone levels, especially in men with low or borderline values. In human trials using standardized extracts, daily supplementation has been associated with improvements in total or free testosterone alongside reductions in cortisol.³,⁴
Researchers propose that tongkat ali may help reduce sex hormone–binding globulin (SHBG), allowing a greater proportion of testosterone to remain biologically active. These effects appear most pronounced in men experiencing stress-related or age-associated hormonal decline, rather than in younger men with already normal hormone levels.³,¹¹
Libido and Sexual Well-Being
Tongkat ali has been studied for its effects on sexual desire and overall sexual well-being. Some trials report modest improvements in libido and sexual satisfaction after consistent use, particularly in men experiencing reduced desire linked to stress or hormonal imbalance.⁵,⁶
While tongkat ali is sometimes discussed in the context of erectile concerns, current evidence more strongly supports its role in sexual desire and perceived performance rather than as a replacement for prescription erectile dysfunction medications.⁹,¹¹
Male Fertility and Sperm Quality
Research has explored tongkat ali’s potential role in male fertility. In studies involving men with suboptimal sperm parameters, supplementation has been associated with improvements in sperm concentration, motility, and morphology.⁷,¹⁰
These findings are thought to be linked to improved testosterone balance and reduced stress-related interference with sperm production. Fertility outcomes depend on many factors, so results should be interpreted cautiously.
Physical Performance, Energy, and Recovery
Tongkat ali has also been examined as a supportive supplement for physically active men. Some studies suggest it may help improve muscular strength, training adaptations, or perceived energy when combined with resistance exercise.⁶
Reductions in cortisol observed in certain trials may contribute to improved recovery and reduced fatigue, particularly during periods of intense training, caloric restriction, or high stress.⁴,⁶ Tongkat ali is not a substitute for training, nutrition, or recovery, but may complement a structured fitness routine.
Stress and Mood Support
One of the more consistent findings in tongkat ali research is its potential effect on stress hormones. Several studies report reductions in cortisol alongside improvements in mood-related measures such as tension, fatigue, or perceived stress.³,⁴,¹⁰
By supporting a healthier stress response, tongkat ali may indirectly benefit focus, energy levels, and overall well-being in men exposed to chronic physical or psychological stress.
How Tongkat Ali Is Commonly Used
Typical Dosage Ranges
Most human studies use doses between 100 and 400 mg per day, with 200 mg of a standardized extract being the most common. Benefits, when observed, generally appear after several weeks of consistent use.³,⁸
Staying within clinically studied dosage ranges is considered the most conservative approach, as long-term safety data at higher intakes are limited.¹¹
Best Practices for Supplementation
-
Choose standardized extracts with clearly labeled bioactive compounds
-
Follow label directions and avoid stacking multiple high-dose supplements without guidance
-
Take earlier in the day if using for energy or stress support
-
Consider periodic breaks rather than continuous year-round use
Prime Labs’ Prime Test – Tongkat Ali Plus is formulated using standardized extracts designed to support testosterone balance, stress response, and overall vitality when used as directed.
Safety Considerations
Possible Side Effects
At commonly studied doses, tongkat ali is generally well tolerated. Mild side effects such as digestive discomfort or headaches have been reported in some individuals.⁹,¹¹
Most safety concerns in the literature involve excessive dosing, contaminated products, or poor-quality extracts. Choosing reputable brands with transparent sourcing and testing significantly reduces risk.¹⁰,¹³
Drug Interactions and Precautions
Tongkat ali may interact with certain medications, particularly those affecting hormones, blood sugar regulation, or liver metabolism. Individuals taking prescription medications or managing chronic health conditions should consult a healthcare professional before use.¹¹
Tongkat ali should be avoided by:
-
Individuals under 18
-
Those who are pregnant or nursing
-
People with hormone-sensitive conditions unless advised by a clinician
How to Choose a Quality Tongkat Ali Supplement
High-quality tongkat ali supplements typically:
-
Use standardized extracts
-
Provide transparent labeling and dosage information
-
Undergo third-party testing for purity and contaminants
Sustainable sourcing is also important, as Eurycoma longifolia is increasingly regulated due to overharvesting. Responsible brands disclose extraction methods and sourcing practices to protect both consumers and natural plant populations.¹²,¹³
Conclusion
Tongkat ali shows promise as a natural supplement for men seeking support for stress management, testosterone balance, sexual well-being, and physical performance. Evidence is strongest in men experiencing chronic stress or low baseline testosterone rather than as a universal enhancer.³,⁴
As with any dietary supplement, results depend on product quality, dosage, individual health status, and lifestyle factors. Tongkat ali should be used as part of a broader approach that includes proper training, nutrition, sleep, and medical guidance when appropriate.
