Vitamin D Supplementation Associated with Lower Suicide Rates in Military Veterans
A study in conjunction with the Department of Veterans Affairs (VA) involving over 1.3 million veterans showed significant benefit from vitamin D regarding incidents of suicide attempts and intentional self-harm.
Supplementation with vitamin D2 or D3 was associated with 45% to 48% reduction in risk of suicide attempts and self-harm. Veterans with pre-study serum levels of vitamin D 25 (OH) D below 20 ng/ml had the most benefit from supplementation and those with measured levels of 40 ng/ml had lower incidence in general.
It should be noted that vitamin D3 supplementation more efficiently increases serum levels of 25(OH) D.
