MODERATE EVIDENCEAdaptogenLast updated April 5, 2026
AVELOR SUMMARY
Rhodiola rosea is an adaptogenic herb traditionally used for fatigue, stress, and cognitive function. Our assessment: moderate evidence supports its anti-fatigue effects and potential mood benefits, but studies are generally small and short-term. It's one of the better-studied adaptogens after ashwagandha, with a favorable safety profile.
