    Rhodiola Rosea for Stress Hormone Regulation

    Rhodiola shows cortisol awakening response effects in small studies.

    Overview

    Rhodiola shows cortisol awakening response effects in small studies.

    Verdict

    Insufficient evidence

    How It Works

    Modulates HPA axis and monoamine signalling under stress load.

    Dosing & Protocol

    Typical dose

    Recommended dose
    200-400mg standardised extract in the morning
    Expected timeframe
    2-4 weeks

    Protocol

    form
    Rhodiola rosea root extract standardised to 3% rosavins and 1% salidroside
    duration
    The cortisol finding appeared over 28 days
    co factor
    Evidence is insufficient for the broad claim. One randomised placebo-controlled trial - Olsson and colleagues, 60 adults with stress-related fatigue - found 576 mg/day reduced the cortisol awakening response over 28 days alongside improved fatigue and concentration, and some acute-stress studies report attenuated cortisol responses. That is the extent of it. No trial has shown normalisation of a dysregulated HPA axis, change in 24-hour cortisol output, effects on ACTH, DHEA or catecholamines, or correction of any diagnosed endocrine abnormality. Regulation implies restoring a system to normal, which has not been demonstrated.
    titration
    Not applicable - no dose-response for hormonal endpoints exists
    starting dose
    Not established as a treatment target. The Olsson trial used 576 mg/day of SHR-5 extract

    Evidence

    What the studies say

    A small trial in burnout patients showed reduced cortisol awakening response. Replication is limited and populations are narrow.

    No studies are yet linked to both Rhodiola Rosea and Stress Hormone Regulation.

    Safety

    Caveats

    Activating in some people. Take early in the day.

    Less likely to help if

    People with genuine endocrine disease, and anyone treating a saliva test result rather than symptoms.
