Big effect

A systematic review of Rhodiola for stress found broad benefits across multiple outcomes — yet the underlying studies were small and varied too much to pinpoint a reliable dose.

This is among the first systematic reviews on Rhodiola for stress; while the results are consistently positive, the evidence is still preliminary and not strong enough for firm recommendations.

Researchers combined data from several small trials involving 590 people and concluded that Rhodiola rosea can reduce stress and anxiety. However, because the studies used different doses (290–1500 mg/day) and had diverse designs, it's unclear how well the effect holds across different populations and what dose works best.

Where this fits in the evidence

This is among the first studies we've indexed on Rhodiola for Reduced Stress — treat it as an early signal until more research accumulates.
