Tongkat Ali has become one of the most searched vitality ingredients in recent years — here's what the research actually says.
Testosterone Support
Several clinical trials have examined Tongkat Ali's effect on testosterone in men with below-average baseline levels, generally finding a supportive effect on levels within the normal range.
Mood and Stress
Some research has also linked Tongkat Ali supplementation to improved mood scores under stress, potentially related to its effect on cortisol.
What It's Not
Tongkat Ali is not a replacement for testosterone replacement therapy and won't meaningfully change hormone levels in men who are already within a healthy range.
