Across 3 studies on Rhodiola for reduced muscle damage, only 1 reported a beneficial small effect that was statistically significant, while 2 studies found neutral effects. The predominant effect size across all studies is small, and the evidence base is too limited to identify a specific effective dose, population, or study duration. The aggregate finding does not support a reliable benefit for muscle damage reduction.
Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Many of the included studies did not reach statistical significance — effect may be smaller than the predominant direction suggests. Most studies were reviews or systematic reviews with limited primary data, and doses were not consistently reported.
Chronic supplementation may positively impact muscle damage during exercise.
Subjects taking RR showed a reduction in pain and muscle damage after exercise training
The effects of RR on muscle damage, inflammation, energy system modulation, antioxidant activity and perceived exertion are presently equivocal.
