Ingredient
Rhodiola rosea extract (3% rosavins, 1% salidroside)
Research dose
200 mg
Evidence: Weak Taken before training: what counts is the amount in the serving you take.
Extract standardized to at least 3% rosavins and 1% salidroside. For endurance, a review of the trials tentatively suggests 200 mg or more about an hour before exercise; trials that found effects on strength and power gave about 1,500 mg a day, about 500 mg of it before exercise. Results are mixed, so the evidence is graded weak.

Supports the research dose. Where: Recommendations for supplementation: "a tentative recommendation of an absolute dose of ≥200 mg RR containing ≥1 % salidroside and ≥3 % rosavin, consumed 60 min prior to exercise"; "a potentially ergogenic dose of RR for strength and power outcomes based on current research would be ∼1500 mg/d, with ∼500 mg consumed within 1 h before commencing exercise".
