Vitamin D supplementation and incident dementia
Oral vitamin D is associated with a suicide attempt and intentional self-harm risk reduction of approximately 45%-48%. Supplementation with higher daily dosages of vitamin D3 was associated with lower suicide attempt and self-harm risk than supplementation with lower dosages. Further, the associated risk reduction in suicide attempt and self-harm was more significant among Black veterans receiving supplementation with Vitamin D than white veterans, among whom low Vitamin D serum levels are more common than among White veterans. As a relatively safe, easily accessible, and affordable medication, supplementation with vitamin D in the VA may hold promise if confirmed in clinical trials to prevent suicide attempts and suicide.
