Rhodiola Rosea for Adrenal Function Support
Rhodiola is used for burnout-type fatigue. Signals are promising but the trial base is small and heterogeneous.
Overview
Verdict
Rhodiola shows short-term benefit for stress-related fatigue in small trials, with inconsistent cortisol effects.
How It Works
Dosing & Protocol
Typical dose
- Recommended dose
- 200-400 mg/day standardized to 3% rosavins
- Expected timeframe
- 1-4 weeks
Protocol
- form
- Rhodiola rosea root extract standardised to 3% rosavins and 1% salidroside - the SHR-5 extract was used in most Scandinavian trials. Adulteration with cheaper Rhodiola species is common, so third-party testing matters
- duration
- 4-8 weeks
- co factor
- Take on an empty stomach in the morning; avoid evening dosing, as it can be activating and disturb sleep. Evidence is mixed and the framing needs care. Rhodiola trials show reduced fatigue and improved stress-related symptoms, and some report reduced cortisol response to awakening or acute stress - which is the basis of adrenal claims. But no trial has measured adrenal gland function, ACTH stimulation response, or corrected any endocrine abnormality. Adrenal fatigue is not a recognised medical diagnosis, and a systematic review found no evidence supporting it as a condition.
- titration
- Increase to 400-600 mg/day, split between morning and early afternoon; doses above 600 mg/day are not better studied
- starting dose
- 200 mg in the morning, 30 minutes before breakfast
