Systematic supplementation targeting nutrient deficiencies can significantly reduce PPD risk. Key interventions: omega-3 (EPA-dominant, 2-3g/day), ferritin optimization (>50 μg/L), vitamin D (4000-6000 IU), magnesium glycinate (300-600mg), and L. rhamnosus HN001 probiotic. A three-phase protocol (prenatal → critical postpartum → extended) addresses the neurobiological cascade triggered by postpartum hormone collapse.
