Vitamin D & Suicide Risk? What Research Actually Shows (2025 Meta-Analysis)

Can low vitamin D levels increase suicide risk?

Research suggests people who attempt suicide often have significantly lower vitamin D levels compared to healthy controls. A 2025 systematic review and meta-analysis in BMC Psychiatry found consistent associations between low vitamin D and suicidal behaviours.

Large population studies, including U.S. veterans research, have also observed lower suicide attempt risk among individuals receiving vitamin D supplementation.

⚠️ Important: This is correlation, not proof of causation. Mental health is complex and influenced by many biological, psychological, and social factors. Nutrition may be one modifiable piece — but professional support saves lives.
