Ashwagandha vs Rhodiola for Stress: Which One Fits You?
Ashwagandha and rhodiola are two of the most-asked-about adaptogens on the Estonian supplement market. Both are marketed "for stress" — but they do very different things and suit different people. This guide helps you decide.

Quick verdict

- Evidence-based dose: ashwagandha KSM-66 300–600 mg/day; rhodiola SHR-5 200–400 mg/day
