Quick Summary

Rhodiola rosea is a plant traditionally used as an adaptogen, with a range of bioactivities including modulation of stress response, antioxidant effects, and potential benefits in mental health and physical performance. Multiple clinical trials and reviews suggest it may support endurance, cognitive function, and stress resilience with a favorable safety profile, although evidence is limited by methodological variability and study heterogeneity.

What is it

Rhodiola rosea, commonly known as Rhodiola or golden root, is a perennial plant found in cold regions of the world. It has been used historically in traditional medicine systems to enhance physical and mental endurance and to help the body adapt to various stressors.

Traditional Uses

Traditionally, Rhodiola has been used as an adaptogen to support the body’s resilience against fatigue, physical stress, and mental exhaustion. It is also used traditionally to boost energy, endurance, and overall well-being.

Active Compounds

Rhodiola contains several bioactive compounds such as rosavin, salidroside, and tyrosol, which are thought to contribute to its adaptogenic, antioxidant, and neuroprotective effects.

Potential Benefits with Evidence Levels

  • Adaptogenic effects reducing stress and anxiety, and improving mental health (Moderate evidence)
    Supported by systematic reviews and narrative analyses showing reduction in stress, anxiety, and depression symptoms (Łuszczak & Kocki 2026; Li et al. 2026; Sánchez et al. 2023).
  • Improvement in physical performance and endurance (Moderate evidence)
    Clinical trials indicate enhanced VO2max, time to exhaustion, anaerobic performance, and cognitive function during exercise (Wang et al. 2025; Koozehchian et al. 2025; Sanz-Barrio et al. 2023).
  • Potential benefits in mild depression (Limited evidence)
    Evidence includes a systematic review featuring a single randomized controlled trial reporting improvement in depressive symptoms compared to placebo (Urata et al. 2025).
  • Possible effects on sleep quality (Preliminary evidence)
    Emerging reviews note improved sleep quality in some studies, though research is still early (Conti 2026; Łuszczak & Kocki 2026).
  • Support in heart failure with reduced ejection fraction (Limited evidence)
    Meta-analysis of standardized Rhodiola rosea injection suggests improvements in left ventricular remodeling and reduced inflammation (Du et al. 2025).
  • Enhancement of immune function (Preclinical and limited clinical evidence)
    Some studies report immunomodulatory effects in patients with non-small cell lung cancer (Cho et al. 2024).

Side Effects

Rhodiola rosea is generally well tolerated with minimal reported adverse effects. Reported side effects are uncommon and typically mild, including occasional gastrointestinal symptoms and dizziness. Randomized controlled trials have not shown a significant increase in adverse reactions compared to placebo or standard treatments.

Drug Interactions

High-quality clinical evidence on drug interactions with Rhodiola is currently insufficient. Caution is advised when using Rhodiola alongside medications affecting monoaminergic systems (such as antidepressants) or cardiovascular drugs, due to possible pharmacodynamic interactions.

Who Should Avoid It

Due to limited data, specific contraindications are not well defined. However, caution is recommended for individuals with bipolar disorder or those currently taking antidepressant therapy until further safety data becomes available. Rhodiola is not recommended during pregnancy or breastfeeding owing to a lack of clinical safety data.

Evidence Limitations

Available clinical evidence is limited by small sample sizes, short duration of interventions, heterogeneity in study designs, and variability in extract standardization. Many studies lack placebo controls and blinding. More rigorous, large-scale, and long-term randomized controlled trials are needed to confirm benefits and establish a comprehensive safety profile.
