Tongkat ali benefits for men: testosterone, libido and safety
Tongkat ali, also called longjack, is a Southeast Asian herb sold as a natural testosterone booster. Interest has grown fast, so it is important to look at what tongkat ali benefits for men are actually supported by research.
In short: Tongkat ali (Eurycoma longifolia) has small studies suggesting it may raise testosterone in men with low levels, ease stress hormones and improve libido and sperm quality. Evidence is promising but limited, and product quality is a real concern, with some products found to contain heavy metals or hidden drugs. Get advice before you use it.
What is tongkat ali?
Tongkat ali is the root of a shrub from Malaysia and Indonesia, traditionally used as a tonic for men. Modern products are usually standardised root extracts.
What the research suggests
Testosterone
Several small trials and a review suggest tongkat ali may increase testosterone, mainly in men whose levels were low to begin with, such as older men or men under stress. Men with normal levels may see little change.
Libido and erections
Some studies reported improved sexual desire and satisfaction. Evidence for erectile dysfunction is weak and inconsistent.
Stress
One small study found lower cortisol and better mood in moderately stressed adults taking tongkat ali.
Fertility
Limited research suggests it may improve sperm quality in men with fertility concerns.
Typical dose
Studies commonly used 200 to 400 mg a day of a standardised root extract, often for 4 to 12 weeks.
Side effects and safety
- Generally well tolerated in short studies, but long-term safety is not well established.
- Possible side effects include restlessness, trouble sleeping and irritability.
- Men with heart conditions, hormone-sensitive cancers, or who take diabetes or blood pressure medicine should get advice first.
Product quality warnings
Testing of tongkat ali products in several countries has found some contaminated with mercury or lead, and some “tongkat” sex products contained undeclared prescription drugs. Only use registered products from reputable suppliers, and avoid unlabelled market products.
Should you try tongkat ali?
If you have symptoms of low testosterone, such as tiredness, low drive, reduced muscle and weaker erections, start by finding out why. Sleep, weight, alcohol and stress all matter.

Our naturopaths can advise whether a herb such as tongkat ali suits you, and refer you to an appropriately registered medical professional if blood tests are needed.
