What it is: Tongkat Ali is the common name for Eurycoma longifolia, a tree native to Southeast Asia whose root is used in traditional preparations.
Evidence context: A randomized trial evaluated a specific standardized Eurycoma extract in young men. Its material, dose and study population should not be treated as identical to this formula.
The formula makes the species, extract ratio and serving amount visible, which is essential when comparing concentrated botanicals.

The formulation rationale
Species + root: The Eurycoma longifolia identity and root source matter more than the common name alone.
Extract ratio + dose: A 200:1 ratio explains concentration but does not by itself establish potency, standardization or clinical equivalence.
Tradition + human research: Traditional use and modern trials can coexist, provided proprietary extracts and different populations are not blurred together.
