Rhodiola Rosea

Daytime energy · Fatigue resistance · Mental performance · Endurance

Rhodiola rosea is a botanical studied in humans for fatigue, mental performance under stress, and exercise-related endurance outcomes. DEXO includes 200 mg in PRIME to support sustained daytime energy, fatigue resistance and performance during demanding days.

200 mg

Part of PRIME / AM, taken in the morning.

Form, dose and role.

What it is
Rhodiola rosea is a perennial botanical whose root and rhizome have traditionally been used in northern European and Asian regions. Its human research is most relevant to fatigue, mental performance under stress, and exercise-related endurance.
Why DEXO chose it
PRIME already supports healthy testosterone and foundational male nutrition. Rhodiola adds a distinct daytime role: sustained energy, resistance to fatigue, mental performance during demanding conditions, and endurance-related support. This helps make PRIME a more complete daytime performance formula.
Why this form
Rhodiola rosea root extract, standardized to 3% rosavins + 1% salidroside. DEXO uses a Rhodiola rosea root extract standardized to 3% rosavins + 1% salidroside — the marker profile used in controlled human performance research. That specification is printed on the label.
Why this dose
200 mg per day of extract standardized to 3% rosavins + 1% salidroside, matching the specification used in controlled human performance research. Rhodiola extracts are not interchangeable, which is why the markers are disclosed alongside the dose.
Its role in the system
Rhodiola supports the daytime-performance side of PRIME. Its role is to support sustained energy, fatigue resistance, mental performance, stress resilience and endurance — complementing PRIME's testosterone and foundational-nutrition ingredients.
