Plain Language Summary
This review of clinical studies found that Rhodiola rosea (also called “golden root”) effectively reduces both physical and mental fatigue. It appears to work quickly, with some benefits seen even after a single dose. Rhodiola also improved thinking ability and focus, especially during stressful situations. Typical doses range from 200-600mg daily of standardized extract. It’s considered safe with few side effects, though it may be too stimulating for some people if taken late in the day.
Key Findings
- 1Significant improvements in physical fatigue symptoms
- 2Enhanced cognitive function under stress conditions
- 3Beneficial effects on mental fatigue and burnout
- 4Acute effects seen with single doses (200-680mg)
- 5Well tolerated with few adverse effects
Abstract
This systematic review evaluated the evidence for Rhodiola rosea in the management of physical and mental fatigue. The review included 11 randomized controlled trials examining fatigue, cognitive function, and stress-related symptoms.
Study Limitations
- Heterogeneity in Rhodiola preparations
- Varying standardization of extracts
- Some studies with small samples
- Need for more long-term studies
