Tongkat Ali, particularly in its LJ100 standardized extract form, is a traditional Southeast Asian botanical that has attracted growing scientific interest. Research suggests that supplementation may help support healthy testosterone levels, with studies indicating potential benefits for mood, stress resilience, and hormonal balance in both men and women. A notable body of research has explored its effects on cortisol, the primary stress hormone, with findings pointing toward improved stress-related mood states and a more favorable cortisol-to-testosterone ratio during periods of moderate stress. Some preliminary studies also suggest it may play a supportive role in body composition and weight management, likely connected to its influence on hormonal pathways. While the research is promising, results can vary and ongoing investigation continues to clarify its broader applications.
