Seasonal affective disorder and mood swings peak in winter, raising interest in omega-3s and vitamin D as a combined strategy. Both nutrients influence neurotransmitters and inflammation, but do they work synergistically? Evidence suggests modest additive effects: omega-3s support membrane fluidity and serotonin signaling, while vitamin D modulates stress hormones. Together, they may reduce depressive symptoms more effectively than either alone. For most adults, 1–2 fatty fish meals weekly plus 1,000–2,000 IU vitamin D supplementation offers accessible insurance. While not a cure-all, this duo provides a practical, evidence-based layer of mood resilience during darker months.
