Burnout and chronic stress are distinct from acute stress and require fundamentally different interventions — adaptogens modulate HPA axis dysregulation rather than simply suppressing it. The strongest human evidence supports Ashwagandha KSM-66 (cortisol ↓27.9% in 8-week RCT, n=272) and Rhodiola SHR-5 extract (only adaptogen with a dedicated burnout RCT showing fatigue reversal). Timing matters critically: Rhodiola in the morning for HPA normalization, Ashwagandha and Magnesium in the evening for cortisol lowering. Supplements are supportive — lifestyle (sleep, exercise timing, nature exposure) is the primary intervention; without it, adaptogens provide marginal benefit.
