A 2022 meta-analysis published in the journal Medicina shows that Tongkat Ali (Eurycoma longifolia) effectively supports testosterone levels in men, particularly in cases of low energy related to physical stress. The 400 mg daily dose falls within the high end of the range validated by randomized clinical trials on this botanical. However, the claim that this optimization occurs primarily through a decrease in SHBG is exaggerated. The same scientific synthesis indicates that the majority of studies measuring SHBG revealed no significant decrease in this protein. The positive effect of this supplement seems to stem instead from a reduction in cortisol, the stress hormone, thereby creating conditions more favorable to overall vitality. Finally, the idea of consuming this product continuously without breaks lacks scientific perspective, as clinical trials generally do not assess its safety for use beyond 4 to 24 weeks.
