What Tongkat Ali is
Tongkat Ali (Eurycoma longifolia) is a Southeast Asian root long used as a men's tonic for energy and vitality.
The 2022 meta-analysis
Pooling five randomized controlled trials, researchers found Tongkat Ali significantly increased total testosterone (PubMed). The authors still called for more research.
Who benefits most
The clearest effect was in men who were low to begin with, the same pattern seen with zinc.
