What It Actually Is
Tongkat Ali (Eurycoma longifolia) is a flowering shrub native to Southeast Asia, with its root used for generations in traditional Malaysian and Indonesian medicine.
What Research Generally Shows
Tongkat Ali has a growing modern research base, studied for its potential role in supporting healthy testosterone levels already within a normal range and reducing stress-related cortisol.
The Honest Gap
ErecPower doesn't disclose the specific amount of Tongkat Ali included, so we can't compare it to doses used in the more promising research (often standardized extracts in the 200-400mg range).
