PRIME / AM

Rhodiola Rosea

Daytime energy · Fatigue resistance · Endurance

Rhodiola rosea is a botanical studied in humans for fatigue, mental performance under stress, and exercise-related endurance outcomes. ROWR 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 ROWR 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
Standardized Rhodiola rosea root extract. ROWR specifies a standardized Rhodiola rosea root extract. Human performance research has used extracts standardized to rosavins and salidroside, so the finished marker-compound specification is printed on the label once it is confirmed with the manufacturer.
Why this dose
200 mg per day. Human research has used standardized Rhodiola extracts across a range of doses, and a 200 mg dose has been used in controlled human performance research with an extract standardized to rosavins and salidroside. Rhodiola extracts are not interchangeable.
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.
