Artic Root Extract
Also known as: Arctic Root Extract, Golden Root, Roseroot, Arctic Root, Rhodiola rosea L.
Overview
Rhodiola rosea, commonly known as Arctic Root or Golden Root, is a perennial flowering plant native to cold, high-altitude regions. Its root extract is widely recognized as an adaptogen, a substance that helps the body adapt to and resist physical, chemical, and biological stressors. Traditionally used to combat fatigue, enhance mental and physical performance, and alleviate symptoms of stress and mild depression, Rhodiola rosea has been the subject of increasing scientific scrutiny. Research, including randomized controlled trials and systematic reviews, supports its efficacy in improving mental health, reducing fatigue, and potentially enhancing exercise performance. It is believed to exert its effects through various bioactive compounds like rosavin and salidroside, which modulate stress response pathways and cellular energy metabolism.
Benefits
Rhodiola rosea offers several evidence-based benefits. For mental health, a phase III randomized controlled trial demonstrated that 340-680 mg/day of standardized extract significantly improved symptoms of mild to moderate depression, including insomnia and emotional instability, with statistically significant reductions in HAMD scores compared to placebo. This suggests a strong potential for mood improvement. Regarding fatigue and physical performance, meta-analyses and RCTs indicate its ability to reduce both mental and physical fatigue. One RCT showed a reduction in C-reactive protein (CRP) after exhaustive exercise, suggesting anti-inflammatory effects, although creatine kinase (CK) levels were unchanged. A systematic review further concluded that Rhodiola supplementation enhances athletic performance and reduces fatigue with no significant adverse effects. While human data on exercise endurance are less conclusive, animal studies suggest it may increase endurance by improving mitochondrial ATP production and glycogen storage, showing promising but not yet definitive results for humans. Across multiple studies, Rhodiola rosea has consistently been well tolerated with no serious adverse events reported, indicating a favorable safety profile.
How it works
Rhodiola rosea's adaptogenic effects are primarily attributed to bioactive compounds such as rosavin, salidroside, and tyrosol. These compounds are thought to modulate the hypothalamic-pituitary-adrenal (HPA) axis, which is central to the body's stress response, thereby increasing resistance to various stressors. It is also believed to enhance mitochondrial function by upregulating ATP synthesis and increasing antioxidant enzyme activity, which helps reduce oxidative stress, particularly in muscle tissue during exercise. Furthermore, Rhodiola may exert anti-inflammatory effects, as evidenced by reductions in biomarkers like C-reactive protein post-exercise. Its adaptogenic properties also involve the modulation of neurotransmitters such as serotonin and dopamine, and stress hormones like cortisol, contributing to improved mood, reduced fatigue, and enhanced cognitive function.
Side effects
Rhodiola rosea is generally considered safe and well-tolerated when taken at doses up to 680 mg/day in clinical trials. Common side effects are rare and typically mild, occasionally including gastrointestinal discomfort or dizziness. While no significant drug interactions have been firmly established, caution is advised when combining Rhodiola rosea with antidepressant medications due to the potential for additive effects, which could theoretically lead to serotonin syndrome or other adverse reactions. Individuals on antidepressants should consult a healthcare professional before starting Rhodiola supplementation. There is insufficient data to recommend its safe use in special populations such as pregnant or breastfeeding women, or children; therefore, these groups should avoid its use. Overall, serious adverse events are uncommon, but users should be aware of the potential for mild side effects and exercise caution, especially if taking other medications.
Dosage
Effective dosages of standardized Rhodiola rosea extract in clinical trials typically range from 340 mg to 680 mg daily. The optimal dosage may vary depending on the specific health goal; lower doses are often used for general fatigue and mental performance enhancement, while higher doses have been studied for symptoms of mild to moderate depression. It is generally recommended to take Rhodiola once or twice daily, preferably with meals, to improve absorption and minimize potential gastrointestinal discomfort. For consistent efficacy, it is crucial to use standardized extracts that specify the amounts of key active compounds, such as rosavin and salidroside. While no strict upper limit has been established, clinical trials have not reported significant adverse effects within this dosage range. Always adhere to product-specific instructions or consult a healthcare professional for personalized dosing advice.
FAQs
Is Arctic Root Extract safe for long-term use?
Limited long-term data exist, but short- to medium-term use (up to 6 weeks) appears safe in randomized controlled trials, with no serious adverse events reported.
How soon do benefits appear?
Improvements in fatigue and mood have been observed within 2-6 weeks of consistent supplementation, though individual responses may vary.
Can it replace antidepressants?
While some evidence suggests efficacy in mild to moderate depression, Rhodiola rosea should not replace prescribed antidepressants without strict medical supervision.
Does it improve athletic performance?
Evidence supports modest improvements in endurance and recovery, particularly in fatigue resistance, but effects can vary by individual and study design.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC9228580/ – This Phase III RCT (Stojcheva et al., 2022) with 91 patients demonstrated that 340-680 mg/day of Rhodiola rosea extract significantly improved symptoms of mild to moderate depression, including insomnia and emotional instability, compared to placebo. It showed statistically significant reductions in HAMD scores, highlighting its potential as an antidepressant adjunct.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC3541197/ – This RCT (Ishaque et al., 2012) involving 30 adults found that Rhodiola rosea reduced C-reactive protein (CRP) levels after exhaustive exercise, suggesting anti-inflammatory effects. However, it did not significantly affect creatine kinase (CK) levels, and no adverse events were reported, indicating good tolerability.
- https://www.frontiersin.org/journals/nutrition/articles/10.3389/fnut.2022.856287/full – This systematic review (Lu et al., 2022) analyzed multiple RCTs and concluded that Rhodiola rosea has positive effects on athletic performance and fatigue reduction. It also noted the low toxicity of the supplement, despite some heterogeneity and small sample sizes in the included studies.
