Editorial evidence review

Rhodiola rosea for stress, cortisol, and fatigue: what the evidence shows

Also known as: golden root, arctic root, roseroot, SHR-5 extract

Evidence grade

Weak evidence

Rhodiola rosea is an adaptogen with several small randomized and open-label trials suggesting reduced stress-related fatigue and burnout symptoms, with inconsistent effects on cortisol itself. Trial quality is mixed, many studies are open-label or industry-linked, and extract standardization (rosavins and salidroside) varies, so the evidence is considered preliminary.

What is Rhodiola rosea?

Rhodiola rosea (golden root) is a dietary supplement commonly marketed for stress, fatigue, cortisol regulation. In the US it is regulated as a food, not a drug, so the FDA does not verify label claims or potency. This page summarizes what peer-reviewed research suggests about Rhodiola rosea and how clinicians typically weigh it against evidence-based prescription options.

Evidence for menopause and hormonal-health uses

Researchers have studied Rhodiola rosea for several symptom clusters relevant to women in perimenopause and midlife. The strongest evidence, where it exists, is summarized below — framed as what studies suggest rather than as clinical guarantees.

  • stress: studies suggest a small, inconsistent effect that may be indistinguishable from placebo.
  • fatigue: studies suggest a small, inconsistent effect that may be indistinguishable from placebo.
  • cortisol regulation: studies suggest a small, inconsistent effect that may be indistinguishable from placebo.
  • burnout: studies suggest a small, inconsistent effect that may be indistinguishable from placebo.
  • mental performance under stress: studies suggest a small, inconsistent effect that may be indistinguishable from placebo.

Typical dosing

Trials commonly use 200-600 mg/day of a standardized root extract (typically 3% rosavins and 1% salidroside, e.g. SHR-5), taken in the morning to avoid sleep disruption, for a few weeks to a few months.

Dosing above is what studies commonly use — it is not a personal medical recommendation.

Side effects and interactions

Common side effects

  • Activating effect — insomnia or jitteriness, especially if taken late in the day
  • Dizziness or dry mouth
  • Irritability at higher doses

Known interactions

  • Antidepressants (SSRIs, MAOIs) — theoretical additive serotonergic effect
  • Diabetes medication — may affect blood sugar; monitor
  • Blood-pressure medication — theoretical interaction
  • Stimulants — additive activating effect; may disrupt sleep if taken late

Who should avoid Rhodiola rosea

Speak to a qualified clinician before starting Rhodiola rosea if you are pregnant, planning pregnancy, breastfeeding, taking prescription medication, or living with a hormone-sensitive condition, kidney or liver disease, a bleeding disorder, or a thyroid condition. Supplement quality varies by manufacturer, so avoid products that do not disclose third-party testing.

Evidence-based alternatives and clinician-guided options

If you are considering Rhodiola rosea for perimenopause or midlife hormonal symptoms, a clinician can help weigh it against options with a stronger evidence base — including hormone therapy, non-hormonal prescriptions, and lifestyle interventions. Our editorial reviews cover telehealth providers that can prescribe and monitor these options:

Weighing costs matters too — our HRT cost estimator compares typical monthly out-of-pocket costs across HRT, non-hormonal Rx, and supplement-only strategies.

Frequently asked questions

Does Rhodiola rosea help with stress?
Rhodiola rosea is an adaptogen with several small randomized and open-label trials suggesting reduced stress-related fatigue and burnout symptoms, with inconsistent effects on cortisol itself. Trial quality is mixed, many studies are open-label or industry-linked, and extract standardization (rosavins and salidroside) varies, so the evidence is considered preliminary.
What is a typical dose of Rhodiola rosea?
Trials commonly use 200-600 mg/day of a standardized root extract (typically 3% rosavins and 1% salidroside, e.g. SHR-5), taken in the morning to avoid sleep disruption, for a few weeks to a few months.
Who should avoid Rhodiola rosea?
Speak to a clinician before starting Rhodiola rosea if you are pregnant, breastfeeding, taking prescription medication (especially Antidepressants (SSRIs, MAOIs)), or living with a chronic condition. Overall, our editorial synthesis rates the evidence as "weak evidence" — it is not a substitute for medical care.
Is Rhodiola rosea FDA-approved?
Rhodiola rosea is regulated as a dietary supplement in the US, not as a drug. The FDA does not verify efficacy claims on supplement labels, and product potency varies by brand. Discuss any supplement with a qualified clinician before starting.
