Form, dose and role.

What it is
Eurycoma longifolia, commonly called Tongkat Ali, is a root traditionally used in Southeast Asia and now one of the more heavily researched botanicals in male performance nutrition.
Why DEXO chose it
Human studies and a systematic review with meta-analysis have investigated standardized Tongkat Ali extracts in relation to testosterone status and male wellbeing. That places it among the small group of ingredients with direct human testosterone research.
Why this form
Standardized Eurycoma longifolia root extract. DEXO specifies a standardized root extract to align with forms used in human research. Where the final production lot uses a branded standardized extract, the exact form is printed on the label and shown on this page.
Why this dose
DEXO uses 200 mg per day, within the range used in representative human studies of standardized extracts.
Its role in the system
Direct human testosterone research exists for standardized extracts, including trials in men with lower baseline testosterone.
