Postpartum brain fog is neurobiologically real — pregnancy reshapes gray matter in regions governing social cognition, and these changes persist for at least two years (Hoekzema et al., 2017). Unlike PPD (where EPA-dominant omega-3 and mood support are primary), cognitive recovery emphasizes DHA repletion for structural brain support, Magnesium L-Threonate for synaptic plasticity, and B-vitamins to restore the methylation cycle depleted by pregnancy. Sleep deprivation is the #1 driver of postpartum cognitive impairment — supplements support recovery but cannot substitute for sleep intervention. Meaningful cognitive improvement typically emerges at 6–12 weeks with consistent DHA + MgT supplementation alongside sleep optimization.

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.
