Across 3 studies, 1 reported a beneficial small effect and 2 reported neutral small effects for Rhodiola supplementation on reducing muscle damage. The evidence is predominantly neutral, with no consistent benefit observed in larger systematic reviews covering over 260 adults.
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.
