THURSDAY, Feb. 2, 2023 (HealthDay News) — Supplementation with vitamin D is associated with a reduced risk for suicide and intentional self-harm among U.S. Veterans, according to a study published online Feb. 1 in PLOS ONE<\/em>.<\/p>\n Jill E. Lavigne, Ph.D., M.P.H., and Jason B. Gibbons, from the Center of Excellence for Suicide Prevention in Canandaigua, New York, conducted a retrospective cohort study of U.S. Veterans supplemented with vitamin D to examine the association with suicide attempts and intentional self-harm. Veterans with any vitamin D3<\/sub> or vitamin D2<\/sub> fill between 2010 and 2018 were matched to untreated control veterans in a 1:1 ratio.<\/p>\n The researchers found that vitamin D3<\/sub> and vitamin D2<\/sub> supplementation was associated with a reduced risk for suicide and self-harm (hazard ratios, 0.552 and 0.512 for vitamin D3<\/sub> and vitamin D2<\/sub>, respectively). Compared with controls, supplemented Black veterans and veterans with 0 to 19 ng\/mL vitamin D serum levels had a significantly lower risk (hazard ratios, 0.362 and 0.359, respectively). Greater risk reductions were seen for supplementation with higher vitamin D doses than lower doses (log average dosage hazard ratio, 0.837).<\/p>\n “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,” the authors write.<\/p>\n
